Payment Terms Contract: What to Include & How to Enforce

Why Your Payment Terms Contract Is the Most Important Clause You're Probably Getting Wrong

I've worked with thousands of agencies and service providers. The number one cash flow problem I see isn't that they can't close deals - it's that they close deals on vague contracts and then spend three weeks chasing an invoice. The fix is almost always the same: they have weak or ambiguous payment terms.

Here's how bad the problem actually is. According to a QuickBooks survey of more than 2,400 small businesses, 56% reported being owed money from unpaid invoices, averaging $17,500 per business. Separately, survey data from Chaser found that 87% of businesses report their invoices get paid after the due date. Nearly 9 in 10. And a Bluevine survey found that nearly 3 in 10 small business owners delayed paying themselves because customers paid late. This isn't a rare edge case - it's the default state of B2B commerce when contracts are weak.

The good news: almost all of this is preventable. Payment terms in a contract are the agreed conditions that define exactly how and when a client must pay for your work. A solid payment terms clause protects your cash flow, eliminates disputes, and establishes professional credibility from day one. A weak one is an open invitation for clients to pay when they feel like it.

This guide breaks down every element you need in a payment terms contract, what each option means in practice, how to handle international clients, what the law actually allows on late fees, and exactly how to write language that stops you from losing sleep over overdue invoices.

What Are Contract Payment Terms - and Why Do They Matter So Much?

Contract payment terms are the specific conditions that govern when, how, and under what circumstances payments must be made between contracting parties. They establish the financial framework for the entire business relationship - defining not just payment schedules but also the consequences of non-compliance, acceptable payment methods, and dispute resolution mechanisms.

Most people treat them as boilerplate. That's the mistake. Your payment terms clause is where your cash flow lives. Get it right, and you have a system. Get it wrong, and you're a collection agency working for free.

The data backs this up hard. According to one report, the average annual cost from late payments hits $39,406 per company. Ten percent of companies suffer over $100,000 in late payment-related expenses. And 64% of small businesses have invoices 90 or more days overdue on their books at any given time. If you think your clients are different, you're probably the owner who hasn't gotten burned yet.

The businesses that get paid on time share one thing: they set explicit expectations in writing before the work starts, and they enforce those expectations consistently. That's it. The magic is in the specificity of the contract, not in having nicer clients.

The Main Types of Payment Terms - and When to Use Each One

Not all payment structures are the same. The model you choose should match the type of work you do, the size of the client, and how much cash flow risk you're willing to carry.

Net 30 (and Net 15, Net 60, Net 90)

Net 30 means payment is due 30 days after the invoice date. It's the most common B2B payment term and the default baseline most professional service contracts start with. Net 15 gets you paid faster and works well with SaaS or recurring engagements. Net 60 is common in enterprise and government contracts where procurement cycles are longer. Net 90 is typically reserved for large enterprise deals or government contracts where the buyer has significant leverage - and it can crush a small agency's cash flow if you're not prepared for it.

Net 30 strikes a practical balance - giving buyers enough time to process invoices through their accounts payable workflow while still allowing sellers to collect cash relatively quickly. But here's the practical rule that most people ignore: the smaller your business, the shorter your payment window should be. Don't let a Fortune 500 logo talk you into Net 90 if you can't float 3 months of payroll.

One tactical note: technology companies often use Net 15, while industries like construction lean toward Net 45 or longer. Know what's standard in your sector before you negotiate - but don't accept extended terms just because a client claims they're standard. Everything in a contract is negotiable.

Due on Receipt

Payment is due the moment the client receives the invoice. This is the most aggressive term from the supplier's perspective, and it's perfectly reasonable for smaller transactions, first-time clients, or situations where you simply don't want to extend credit. Some clients will push back - but the clients worth keeping usually don't. The clients who howl the loudest about immediate payment terms are often the same ones who would've gone 60 days past due anyway.

Upfront / Advance Payment

The client pays before you start work. This is the gold standard for protecting yourself on new relationships. It eliminates all collection risk on the front end. The downside is that some clients will walk - but those are often the same clients who would've been slow-pay nightmares anyway. For retainer-based agency work, a widely-used clause structure looks like this: "Client will pay the retainer fee in advance each month, which is earned on receipt in exchange for the reservation of the resources described in this SOW."

Milestone Payments

For larger projects with distinct phases - website builds, marketing campaigns, software launches - milestone payments tie your invoice directly to deliverable completion. A common approach is a 50/50 split: 50% upfront to begin work, 50% upon final delivery. For more complex builds, a three-part structure works well: 30% upfront, 40% upon delivery of a beta or midpoint, and 30% after final delivery and client acceptance. This keeps both sides accountable and aligns your compensation with progress rather than arbitrary calendar dates.

Installment Payments

The total project fee is broken into multiple smaller payments at agreed intervals. This works well for high-ticket engagements where a lump sum is a sticking point for the client, but you still want predictability. Just make sure each installment date is explicitly written out in the contract - "payable in three equal installments on the 1st of each month" beats "payable in installments" every single time. Ambiguity here always resolves in the client's favor.

Early Payment Discounts (2/10 Net 30)

This means the buyer gets a 2% discount if they pay within 10 days; the full amount is due in 30 days. On a $10,000 invoice, paying within the discount window saves the client $200. It's a useful incentive structure when you need faster cash collection and your client has the liquidity to act early. Research consistently shows that early payment discounts like 2/10 Net 30 often accelerate payments more effectively than penalties alone - so if you're torn between a carrot and a stick, the carrot often works better for willing payers. Just run the math - that 2% discount applied across your whole book of business adds up fast. Don't offer it if your margins can't sustain it.

Cash Before Shipment (CBS) and Cash with Order (CWO)

These terms are more common in product-based businesses, but service providers can adapt the logic. CBS requires a down payment before delivery; the down payment typically covers 25% to 50% of the total invoice value at minimum, protecting you from loss if the client walks. CWO requires full payment before production even begins. If you do highly customized work - custom software builds, bespoke creative, long research projects - consider CWO or a significant upfront percentage. You're investing real time and resources before anything ships.

The 6 Elements Every Payment Terms Clause Must Include

Vague contracts create disputes. Specific contracts get you paid. Every payment terms section in your contract should spell out all six of these elements clearly.

• Payment due date: State the exact window - "Payment is due within 30 days of the invoice date" - and specify whether the clock starts on the invoice date, delivery date, or receipt date. Most B2B contracts use the invoice date. Make it explicit. "Payment due within 30 days" with no anchor date is an invitation for a debate you don't want to have.
• Invoice details and PO requirements: Require that the invoice reference a specific purchase order or project name, and specify the exact amount. This eliminates the "we can't process this without a PO number" delay game that large clients play constantly. If they need a PO, make it their responsibility to provide one within a set number of days of contract signing - not your problem to chase after you've already delivered work.
• Accepted payment methods: Clearly state how you accept payment - bank transfer (ACH), wire, credit card, check. Removing friction from the payment process speeds collection. Include routing numbers or a link to your payment portal in every invoice. The easier it is to pay you, the faster you get paid. On the flip side, specify who covers transaction fees for wire transfers or credit card processing - don't assume the client knows.
• Late payment penalties: This is non-negotiable. Without a late fee in the contract, you have no enforcement leverage. A typical policy charges 1.5% per month on overdue balances, often with a short grace period. Write it into the contract explicitly: "Overdue amounts shall accrue interest at a rate of one and one-half percent (1.5%) per month, or the maximum rate permitted by applicable law, whichever is less." Always include the "whichever is less" language to stay compliant across jurisdictions. The practical reality: only 19% of small businesses actually charge late fees on overdue invoices, even though 59% experience late payments. That gap is your leverage - use it.
• Suspension of services: Your contract should state clearly that you reserve the right to pause work if a payment goes unpaid past a certain threshold. This is your most powerful enforcement mechanism. Don't keep delivering value to a client who hasn't paid last month's invoice. The moment you continue working for free, you've signaled that the late fee and the suspension clause are empty threats.
• Dispute resolution: Outline how payment disputes will be handled - arbitration, mediation, or specific court jurisdiction. Include a deadline for raising disputes: "Any disputes regarding invoice amounts must be submitted in writing within 10 days of the invoice date." After that window closes, the invoice is deemed accepted. This single clause eliminates the "we have concerns about the invoice" stall tactic that sophisticated clients use to run out the clock.

Sample Payment Terms Contract Language You Can Use

Stop trying to write this from scratch. Here's a clean, practical template you can adapt:

"Payment Terms: All invoices are due and payable within [15/30] days of the invoice date. Client agrees to pay via [ACH / wire transfer / credit card]. Invoices unpaid after the due date shall accrue interest at a rate of 1.5% per month on the outstanding balance, or the maximum rate permitted by applicable law, whichever is less. A grace period of [5] business days applies before late fees are assessed. Service Provider reserves the right to suspend all services immediately upon non-payment of any overdue invoice. Transfer of ownership or license of any deliverables occurs only upon receipt of payment in full. Any disputes regarding invoice amounts must be submitted in writing within [10] days of the invoice date; failure to dispute within this window constitutes acceptance of the invoice."

Short. Specific. Enforceable. You can pull our free Agency Contract Template and customize this language directly into it, or use our One-Page Contract Template if you want something lighter for smaller engagements.

Retainer Contracts: Special Payment Terms Considerations

If you run a retainer-based agency - and most of the agencies I work with do - your payment terms need additional structure beyond a standard project contract.

The single most common mistake I see is treating a retainer like a post-work invoice instead of a pre-work reservation. A retainer is payment for your availability and capacity. The moment a client treats it like an invoice-after-delivery model, scope creep and non-payment become inevitable.

For retainer contracts, your payment terms should cover:

• Advance billing: The retainer fee should be billed and paid before work begins each period - not after. This protects your time and signals to the client that they're reserving capacity, not just buying deliverables.
• Non-refundability: Include language stating the retainer is non-refundable once the period begins. This prevents clients from requesting refunds mid-month because "we didn't use all the hours."
• Overage rates: If you bill by hours, specify your overage rate explicitly. Ambiguity here leads to awkward conversations at the worst possible time.
• Automatic renewal and payment: If your retainer auto-renews, say so in the contract. The client should know that the next month's invoice generates automatically on a specific date unless they've provided written termination notice within the required window.
• Termination notice: Most retainer agreements include a 30-day termination notice requirement. This gives both parties time to wind down cleanly and ensures you're not left without income while scrambling for a replacement client.
• Work holdback: It's reasonable - and common - to retain ownership of deliverables until invoices are paid in full. Include a line stating that transfer of ownership or license occurs upon receipt of payment. This is one of the most underused leverage points in agency contracts.

How to Handle International Clients in Your Payment Terms Contract

Domestic payment terms are relatively straightforward. International clients add a layer of complexity that most service providers don't account for until they're already in the middle of a currency dispute or a wire transfer that arrived $200 short because of undisclosed intermediary bank fees.

Here's what your payment terms need to address when working across borders:

Currency Specification

Always specify the currency in which you will be paid. "All payments to be made in USD" is sufficient - but make it explicit. Currency fluctuations between contract signing and invoice payment can materially change what you actually receive. If you're comfortable accepting payment in the client's local currency, specify the exchange rate source and date for conversion calculations, and add a short clause confirming the currency: "All amounts are payable in [USD/EUR]. Client bears full responsibility for any currency conversion fees or exchange rate differences."

Extended Payment Windows

International payments often require longer processing windows due to banking delays and currency conversion. Consider extending terms by 15 to 30 days for international clients beyond your standard domestic window. A client in the UK paying via international wire transfer to a US account has more friction in the process than a domestic ACH. Build that into the contract so neither party is surprised.

Who Pays the Wire Fees

Specify clearly who is responsible for any international bank transfer fees. Traditional wire transfers move through correspondent banking networks and routinely incur multiple intermediary fees along the way. If you don't address this in the contract, you'll regularly receive short payments and have an awkward conversation about whether the client needs to top up the difference. One line in the contract saves you months of irritation.

Tax and VAT Obligations

For international contracts, include a clause clarifying tax responsibilities. Depending on the jurisdiction, value-added tax (VAT), withholding tax (WHT), or goods and services tax (GST) may apply. The contract should specify which party is responsible for local tax obligations and whether invoiced amounts include or exclude applicable taxes. This isn't just good practice - it's essential to avoid compliance risk.

Governing Law

State explicitly which country's laws govern the contract and where disputes will be resolved. Without this clause, a payment dispute with an international client becomes a jurisdictional nightmare. Pick the jurisdiction where you operate, and make sure it's in the signed agreement before work starts.

How to Negotiate Payment Terms Without Losing the Deal

Most people treat payment terms as a take-it-or-leave-it item. Experienced operators know they're negotiable - the leverage just depends on which side of the table you're on.

If you're a supplier pushing for shorter terms, lead with the discount card. Offering 2% off for payment within 10 days is often cheaper than carrying 60-day receivables on your balance sheet, and clients with good cash positions love the savings. This creates a genuine win-win: you get cash faster, they pay less.

If you're dealing with an enterprise buyer pushing for Net 60 or Net 90, don't just roll over. Counter with milestone payments or a partial upfront - structure it so some cash lands in your account before you've delivered 90 days of work on faith. Large enterprises with strong balance sheets regularly push for extended terms as a default tactic with smaller suppliers. Push back with data: if you can show them your standard terms, most procurement teams will accept a reasonable counter. The key insight is that large enterprises use extended terms to effectively borrow money from their suppliers for free. You are not a bank. Don't act like one.

For new clients specifically, require upfront payment or at minimum a 50% deposit. You don't know these people yet. Your contract should reflect that risk, not paper over it. Starting a new client relationship with Net 30 is extending credit to a stranger. Starting with 50% upfront is professional and signals that you run a serious operation.

One more negotiation tactic worth knowing: term graduation. Start new clients on shorter terms and "graduate" them to more favorable terms only after they've established a track record of on-time payment. This significantly reduces exposure to bad debt while still giving good clients the terms they eventually earn.

How to Structure Payment Terms by Client Type

Not every client gets the same terms. Smart operators segment their payment policy by risk profile, not by how much they like the client. Here's a practical framework:

New Clients (Unknown Payment History)

Require 50% upfront minimum, with the balance due on a fixed date or upon delivery - whichever comes first. No exceptions until they've proven they pay on time. New clients who refuse upfront payment terms when asked professionally are a yellow flag. New clients who argue loudly about it are a red flag.

Established Clients (Strong Track Record)

Net 30 is a reasonable default for clients with a proven history of on-time payment. If they've been consistently early, you can explore Net 45 as a goodwill gesture - but don't offer it proactively. Let them ask, which gives you a negotiation moment where you can get something in return (a contract extension, a rate increase, a referral commitment).

Enterprise / Fortune 500 Clients

Large companies have procurement teams specifically trained to push terms as long as possible. Go in expecting to negotiate. Your opening position should be shorter than what you'll accept. Counter Net 90 demands with a milestone payment structure that gets at least 30-40% of the fee in your account before the engagement is halfway through. If they insist on Net 90, factor the cost of carrying that receivable into your pricing.

Government Contracts

Government clients often have mandated payment cycles that you can't change. What you can do is price your work to account for the longer collection window, make sure your invoice format matches their exact requirements (wrong format = delayed payment), and submit invoices immediately upon completion of each deliverable milestone rather than waiting until the end of the engagement.

Late Payment Penalties - What the Law Allows and How to Structure Them

Late fees are only enforceable if they're in the contract before the payment is late. You cannot add a late fee to an invoice after the fact and expect to collect it. Get it in the signed agreement first.

There are three main structures for late payment penalties in B2B contracts:

• Percentage-based interest: The most common approach for B2B contracts. You charge a percentage (typically 1.5% per month) on the overdue amount. On a $10,000 invoice, that's $150 per month. It escalates with each passing billing cycle, which creates increasing pressure on slow payers. Always include the "or the maximum rate permitted by applicable law, whichever is less" language - late fee caps vary by state.
• Flat fee per period: A fixed dollar amount added to overdue invoices. Simpler and more predictable, but less effective on large invoices where a flat fee feels trivial. Better suited for small transactions or freelance work where percentage-based math creates awkward small numbers.
• Hybrid structure: Some businesses combine both approaches - a flat fee (say, $25 or $50) triggers immediately when an invoice goes past due, then percentage-based interest accrues monthly if the invoice remains unpaid. This provides an immediate deterrent plus ongoing pressure for extended delinquencies.

One nuance worth knowing: late fees are typically assessed per contractual agreement, not automatically by law in most US states. The invoice sending the fee should reference the specific clause in the signed contract that authorizes the charge. This paper trail matters if you ever need to escalate to collections or small claims court.

Enforcing Late Payments: What Actually Works

Writing the right terms is step one. Enforcing them when a client goes quiet is step two - and most service providers get it wrong.

The data is revealing here: 60% of small business owners say they avoid confronting clients over delinquent bills out of fear of damaging the relationship. Meanwhile, 53% of those same businesses have had to turn down growth opportunities because of reduced cash flow from overdue invoices. They're protecting a relationship with a client who is actively damaging their business. That's backwards.

When an invoice goes overdue, move through this sequence fast:

• Day 1 past due: Send a brief, professional email referencing the invoice number, due date, and the late fee clause in your contract. Keep the tone neutral - most late payments at this stage are administrative oversights, not bad faith. A politely worded reminder often resolves it immediately.
• Day 7 past due: Follow up by phone. Email is easy to ignore. A direct call to your main contact (or anyone at the company if your main contact has gone dark) often surfaces whatever's blocking the payment - missing PO number, wrong invoice format, approval chain delay. Solve the administrative problem and your money usually arrives within days.
• Day 15 past due: Invoke the work suspension clause. Don't keep delivering if they haven't paid for last month. Send a written notice stating that per Section [X] of your agreement, services are paused effective immediately pending payment of the outstanding balance. This is the most effective lever you have - clients who want the work to continue will suddenly find a way to process the invoice.
• Day 30+ past due: At this point you're looking at formal collections or legal action. Keep records of every communication attempt - dates, channels, responses. Never keep working for a client who refuses to pay without cutting off your output first. Your leverage drops to near zero the moment you complete and deliver the final deliverable.

The key insight here: structure your payment schedule so you always have something they want that you haven't handed over yet. Intellectual property transfer, final files, account credentials, access codes - these are leverage. Retain them until payment clears. This is why the work holdback clause in your contract isn't just legal protection; it's a cash flow enforcement mechanism.

Using Invoicing Tools to Automate Payment Enforcement

The contract sets the terms. Your invoicing process is where those terms either get enforced automatically or fall apart due to human error and inconsistency.

Research from the QuickBooks late payments report found that businesses with lower digital adoption rates were significantly more likely to experience late payments - specifically, 4 to 28% higher digital adoption rates were found among businesses less affected by late invoice payments. The businesses that get paid on time are using systems, not just writing better contract language.

Here's what an effective invoicing system does for you:

• Sends invoices automatically on the trigger date - invoice date, milestone completion, or recurring billing cycle - so nothing falls through the cracks because you forgot to invoice.
• Sends automated reminders before the due date (not just after), on the due date, and at regular intervals after the due date, so you're not manually tracking 30 open invoices across 30 spreadsheet rows.
• Calculates and adds late fees automatically based on the contract terms, so you don't have to have the awkward "I need to add a late fee" conversation - it just shows up on the next statement.
• Provides a direct payment link in every invoice, reducing friction to a single click for the client.
• Maintains a complete audit trail of when invoices were sent, opened, and paid - critical documentation if you ever escalate to collections or legal action.

CRM tools like Close can help you track client communication history alongside deal and invoice data, which is useful when you need to document a non-payment escalation. If you're managing a high-volume client roster, project management platforms like Monday.com also integrate invoicing and contract milestones in a way that reduces the manual tracking burden significantly.

Common Payment Terms Mistakes That Cost Agencies Real Money

A few patterns I see over and over with the agencies I work with:

• Mismatched contract and invoice terms: The contract says Net 30, the invoice says Net 15. This discrepancy creates disputes that delay payment and embarrass you professionally. Make sure your invoices mirror the contract language exactly. When in doubt, pull the contract and copy-paste the terms onto the invoice footer.
• No late fee clause at all: Without a contractual basis for the late fee, you can't enforce it. A credit manager who adds a fee to an invoice without contract backing is creating a dispute, not enforcing a policy. Get it in writing before the work starts.
• Vague start date for the payment clock: "Payment due within 30 days" - 30 days from what? Invoice date? Delivery? Receipt? State it explicitly. Most B2B contracts use the invoice date; just say so in plain language.
• Mixing payment models in one SOW: Don't write a contract where one paragraph quotes a flat fee and another references hourly billing. These hybrid structures create ambiguity that always resolves in the client's favor, not yours.
• No work suspension rights: If your contract doesn't give you the right to pause services for non-payment, you're contractually obligated to keep working even when you're not getting paid. Fix this before you sign the next one.
• No dispute window clause: Without a stated deadline for the client to raise invoice disputes, they can challenge an invoice months after delivery. A 10-day dispute window clause eliminates this tactic entirely.
• Ignoring international payment complexity: If you work with overseas clients and your contract doesn't specify currency, who pays wire fees, and governing law, you're building in conflict. Every international contract needs these elements explicitly addressed.
• No IP holdback language: Delivering final files before payment clears is giving away your only remaining leverage. Transfer of intellectual property and deliverables should always be conditioned on receipt of payment in full.

What Happens When You Have to Actually Collect

At some point, if you run an agency or service business long enough, you'll face a client who simply refuses to pay. Here's how to handle it without destroying your reputation or wasting months in limbo.

Demand Letter

Before you involve a lawyer or collections agency, send a formal written demand letter via certified mail and email. Reference the contract, the specific clause they're violating, the total amount owed including any accrued late fees, and a deadline for payment (typically 10 to 14 business days). The act of sending a formal letter on letterhead, even without a lawyer, resolves a surprising percentage of disputes because it signals that you're serious and organized.

Collections Agency

For invoices under a certain threshold where legal action isn't cost-effective, a commercial collections agency is worth considering. They typically work on a contingency fee basis - they take a percentage (often 25-40%) of what they collect. You lose some of the amount, but you recover something from what might otherwise be a write-off. Only use agencies with B2B commercial collections experience, not consumer debt collectors - the regulatory environments and tactics are different.

Small Claims Court

For invoices in the range that qualifies for your state's small claims court (limits vary by state, typically between $5,000 and $25,000), this is often faster and cheaper than hiring a litigation attorney. You'll need your signed contract, invoices, and documentation of your collection attempts. Having clean paper trail from day one - which your contract and invoicing system should provide automatically - makes small claims filings almost routine.

When to Walk Away

Some debts cost more to chase than they're worth. If a client owes you a small amount, has no assets, and the legal fees plus time cost exceed the balance, write it off, document it for tax purposes, and blacklist the company from future engagement. The write-off is at least partially recoverable as a business bad debt deduction. The three months of stress chasing $2,000 is not.

Proactive Strategies That Prevent Late Payments Before They Start

The best enforcement strategy is one you never have to use because the client pays on time. Here's what the agencies with the strongest payment cultures do differently:

Conduct Basic Due Diligence Before Signing

Before you extend credit terms to any client, do the same basic diligence you'd do before any significant business decision. How established is the business? Does the company have a history of on-time payments with other vendors? Is there a pattern of disputes or complaints? Ask for a reference from another vendor they currently work with. Most legitimate clients with good payment practices won't object to this - the ones who do are telling you something.

Discuss Payment Terms During the Sales Conversation

Don't bury payment terms in the contract and hope the client doesn't notice until after they've signed. Walk them through your payment structure during the sales conversation. Explain why you require upfront payment or a deposit (it's how you protect both parties and ensure project continuity). Clients who agree to terms they've discussed out loud are significantly more likely to honor them than clients who felt surprised by terms buried in fine print.

Use Electronic Invoicing with Payment Links

The easier it is to pay you, the faster you get paid. Every invoice should have a direct payment link - not instructions for how to initiate a wire transfer. Every additional step between the client's intention to pay and the actual payment is friction that delays you by days. Businesses that use digital invoicing and payment links consistently collect faster than those relying on check or manual wire requests.

Invoice Immediately

Don't let invoices pile up. Invoice at the trigger point - completion of a milestone, end of the billing period, or start of a new retainer cycle - not whenever you get around to it. Every day you delay sending an invoice is a day added to your collection timeline. Industries that bill on project completion, including consulting, creative services, and professional services, tend to feel payment pressure the most precisely because they often delay invoicing after delivery.

Set Up Recurring Billing for Retainer Clients

For retainer clients, recurring billing through a payment platform eliminates the invoice-chase cycle entirely. The client authorizes automatic payment, the payment runs on schedule, and the invoice is generated automatically as a record. You do the work; the payment shows up. This is how the most efficient agencies operate their retainer books.

Get Your Contract Right Before the Conversation Even Starts

The best time to establish strong payment terms is before you have a client relationship to protect. That means starting with a well-structured template, not a blank Google Doc you cobbled together the night before the kickoff call.

Grab our free Agency Contract Template - it includes a complete payment terms section, termination language, scope protection, and IP ownership clauses. If you're proposing to new clients and want something that converts prospects while locking in the right commercial terms, our Proposal AI Templates include payment term language built directly into the proposal structure so there's no gap between what they sign and what you invoice.

If your engagements are smaller or you want something leaner for quick-close deals, our One-Page Contract Template covers the essentials without the overhead of a full MSA.

For anyone working through more complex contract structures or trying to pressure-test their payment terms with operators who've been on both sides of these agreements - I go deeper on this inside Galadon Gold.

Get the contract right once. Stop renegotiating it on every deal. And stop finishing the work before the money is in your account - that's the single most expensive habit most service providers have, and it's entirely within your control to change.

Payment Terms Contract - Quick Reference Cheat Sheet

Here's a fast reference summary of everything covered in this guide:

• Net 30: Most common B2B default. Invoice due 30 days from invoice date.
• Net 15: Faster collection, works well for SaaS and recurring work.
• Net 60/90: Enterprise and government standard. Price your work to account for the float.
• Due on Receipt: Best for new clients and smaller transactions.
• 50% Upfront: Standard best practice for new client relationships. Non-negotiable.
• Milestone Payments: Tie invoices to deliverable completion. 30/40/30 or 50/50 are common splits.
• 2/10 Net 30: Early payment discount. Often accelerates collection better than penalties alone.
• Late Fee Rate: 1.5% per month is standard. Always include "or max rate permitted by law."
• Dispute Window: 10 days from invoice date. After that, invoice is accepted.
• IP Holdback: Ownership transfers only upon payment in full. Non-negotiable.
• Suspension Clause: You have the right to pause work for non-payment. Use it.
• International Clients: Specify currency, who pays wire fees, and governing law. Extend terms 15-30 days to account for banking friction.

Every one of these elements belongs in your contract before you send a proposal. Not after you've already started the work. Not after the first invoice goes unanswered. Before. Get the template, adapt the language, and stop running your business on handshake deals and hope.
