This payment plan agreement is written for businesses offering instalments to a customer, not for personal loans. It records the balance and the invoices it covers, the deposit, the instalment schedule, autopay authority, and exactly what happens if a payment is missed. Download it free below in Word or PDF, no email required, then walk through every clause so you know what you are signing people up to.

Key takeaways

  • Nearly every free payment plan agreement online is a debtor and creditor loan document. This one names a Business and a Customer, references the invoices, and is built to be enforced by your AR process afterwards.
  • The clauses that do the real work are the acknowledgment of the balance, the autopay authority, and acceleration on default. Most templates skip at least two of them.
  • If you regularly let consumers pay in more than four instalments, US Truth in Lending rules can apply to you. Business-to-business plans generally sit outside them. Know which lane you are in.
  • A signed agreement is half the system. Reminders per instalment, auto-charging, and late fees on misses are what make the schedule stick.

Three documents cover the whole arrangement. Fill in the bracketed fields, have your lawyer sanity-check anything sizeable, and keep a signed copy with the invoice.

Payment plan agreement
The signed contract: parties, invoices, balance acknowledgment, deposit, schedule table, autopay, late instalments, acceleration.
Arrangement offer letter
For an overdue balance: the written offer that puts a deposit, dates, and consequences on the table today.
Autopay authority
Card or direct debit authorisation for the schedule, so instalments collect themselves instead of relying on memory.
Free, no email wall. Templates are general information, not legal advice: laws differ by state and country, so have a lawyer review before relying on them for large balances or consumer customers.

Why this template is different

Search this term and the results are loan documents: a Debtor acknowledges owing a Creditor, with clauses about collateral and promissory notes. Fine for lending a mate $5,000. Wrong shape for a business that has invoiced a customer and agreed to spread the payment, which is who actually needs this page.

This agreement starts from the invoice. The parties are a Business and a Customer, the balance is tied to invoice numbers and original due dates, the deposit is the first instalment, and the payment method clause assumes autopay because arrangements that rely on the customer remembering to pay have a short life expectancy. It also assumes something no template site mentions: a document only works if something enforces it afterwards. Every clause here maps to a thing your AR process can actually do, remind, charge, apply a fee, accelerate.

Every clause, explained

Ten clauses, each earning its place. Copy the wording, adapt the bracketed parts, delete nothing until you know why it is there.

Acknowledgment of the balance
Why it matters: if the plan collapses and you end up in court, this clause stops the customer arguing the work was faulty or the debt disputed. They signed a document agreeing the balance is owed. It is the single most valuable sentence in the agreement.
The Customer acknowledges owing the Business the total of [AMOUNT] under invoice(s) [NUMBERS] dated [DATES], confirms the underlying goods or services were delivered as agreed, and raises no dispute over the Balance.
Deposit as the first instalment
Why it matters: a customer who cannot fund a deposit today will not fund instalment four either. The deposit is your commitment test and your loss ceiling in one. 20 to 30% is the working norm for overdue balances, up to 50% for new work.
The Customer will pay a deposit of [AMOUNT] ([%] of the Balance) on signing this Agreement. The deposit is the first instalment under the Schedule.
The schedule, with exact dates
Why it matters: "monthly" is an argument waiting to happen. "$1,575 on the 1st of each month from 1 September to 1 December" is collectable. Use the builder below and paste the table straight in. Instalments do not have to be equal: a fixed weekly amount with a final settlement payment for the remainder is common and completely fine, as long as it is written down.
The Customer will pay the remaining Balance in the instalments set out in the Schedule. Time is of the essence for each payment date.
Autopay authority
Why it matters: the plans that complete are the ones nobody has to remember. Card or direct debit authority signed with the agreement turns ten collection conversations into zero. No generic template includes this clause; it is the difference between a plan and a promise.
Payments will be collected automatically by [card / direct debit] under the authority signed with this Agreement. The Customer will keep a valid payment method on file for the life of the Schedule.
Late and failed instalments
Why it matters: a payment plan is not a fee holiday. Keeping your standard late fee and interest live on missed instalments preserves the incentive to keep the plan current. Rates differ by region: in the UK, statutory interest on late commercial payments runs at 8% plus the Bank of England base rate (11.75% at July 2026) even without a clause; in the US, 1 to 2% per month is the convention, subject to state caps; in Australia and New Zealand the clause itself is the entitlement, so write it in.
If an instalment fails or is not paid on its date, the Business may charge a late fee of [AMOUNT] and interest at [RATE] on the overdue amount, and may re-attempt collection.
Default and acceleration
Why it matters: without acceleration, a customer who stops paying at instalment three of ten technically only owes you the missed instalment, and you get to chase the rest one month at a time. This clause makes the whole remaining balance fall due after a short cure window, which is the leverage that gets a stalled plan moving again.
If an instalment remains unpaid [7] days after its date, the Customer is in default and the whole remaining Balance, plus accrued fees and interest, becomes immediately due and payable without further notice.
Costs, no waiver, and whole balance preserved
Why it matters: three short clauses that close the exits. Recovery costs shift agency and legal fees to the defaulting customer where the law allows. No waiver means accepting one late payment does not rewrite the schedule. And stating the arrangement is not a settlement stops anyone claiming the plan discounted the debt.
The Customer will reimburse the Business for reasonable costs of recovery, including collection agency fees and legal costs, to the extent permitted by law. Accepting a late or partial payment does not waive the Business's rights or vary the Schedule. This Agreement is a payment arrangement, not a settlement, release, or novation.

Build the schedule

Enter the numbers, get the table, paste it into clause 3. The running balance column is what makes the schedule auditable at a glance.

DateAmountRunning balance
Rounding lands in the final instalment, so the last payment settles the exact remainder. That mirrors how real plans are run.

Four instalments is a legal line in the US

One distinction no template site mentions. Under US Truth in Lending rules, a business that regularly extends credit to consumers, payable in more than four instalments or carrying a finance charge, can meet the definition of a creditor under Regulation Z, with formal disclosure obligations to match. "Regularly" has a specific meaning (broadly, more than 25 such extensions in the preceding year), and business-purpose credit is exempt.

The practical read: B2B payment plans on invoices sit outside this regime. If your customers are consumers and instalment plans are part of how you sell, keep plans to four payments or fewer, or get proper advice before scaling the programme. Australia runs a similar split: the National Credit Code covers credit for personal and household purposes, while business-purpose arrangements generally sit outside it. Not legal advice, just the map of which lane you are in.

A template is half the system

Here is what happens to most signed payment plans: they get filed, the first instalment arrives, the third one quietly does not, and nobody notices until month end. The agreement gave you rights; nothing exercised them.

That second half is what Paidnice does. Set the plan up on the actual invoice in Xero or QuickBooks and the schedule is written onto the invoice and the customer PDF, instalments auto-charge through Stripe or Pinch Payments under the authority you just collected, reminders run before and after every instalment, and a missed one triggers your late fee instead of your memory. Deposits work as the first instalment, any frequency works, and uneven amounts (weekly payments with a final settlement) are fine. Plans are included on Pro plans from US$99 a month, and customers cut their average wait for payment in half within 30 days. The payment plans feature page has the two-minute tour, and the payment plan calculator models amortisation and interest if you charge it.

Common questions

How do I write a payment plan agreement?

Name both parties and the invoices, state the balance with an acknowledgment that it is owed, set a deposit (20 to 30% is the norm for overdue balances), lay out every instalment date and amount in a table, attach autopay authority, keep late fees and interest live on misses, add acceleration on default with a short cure window, and have both parties sign before the first payment date.

Is a payment plan agreement legally binding?

Yes. It is an ordinary contract: offer, acceptance, and consideration on both sides (you give time, they commit to a schedule). The acknowledgment clause also strengthens your position on the underlying debt if you ever need to enforce it. For large balances or consumer customers, have a lawyer review the wording for your jurisdiction.

Does it need to be notarised?

Usually not; signatures are enough for an ordinary commercial arrangement. Some businesses notarise very large balances as belt and braces, and some US states have specific requirements in consumer contexts, which is a question for your lawyer rather than a template.

What deposit should I ask for?

20 to 30% for an arrangement on an overdue balance, and up to 50% when the plan is agreed before work starts. The deposit tests commitment and caps your downside. A customer who cannot fund any deposit is asking for unsecured credit, not a payment plan.

Can I charge interest on a payment plan?

Generally yes for business customers, at your contractual rate: in the UK statutory interest of 8% plus the Bank of England base rate applies to late commercial payments regardless, in the US contract rates around 1 to 2% per month are typical subject to state caps, and in Australia and New Zealand the written clause is what creates the right. Consumer plans can trigger credit regulation; see the section above.
