What this builds

A single document: the signed payment plan for a customer who owes you money and cannot pay the balance at once. It records five things: the outstanding balance both parties agree on, the down payment the customer makes now, the installment schedule for the rest, what happens if a payment is missed, and the late-fee terms that already apply under your own agreement. Fill the fields, print two copies, and both parties sign. There is no signup and no email wall, and the draft saves in your browser rather than on a server.

This page sits one step past the past due invoice letter template, whose final notice sets a date and offers an arrangement. When the customer’s answer to that notice is “I can pay half now,” this is the document that makes the arrangement real.

The balance: one number, not two invoices

The “Total amount now owed” field is one number that covers the invoice and any late fees already applied. Do not split it. If your service agreement provides for a late fee, work the figure on the invoice late fee calculator first, add it to the original invoice amount, and enter the total. The agreement then records the figure both parties agree on, and no one needs to re-derive the fee during a dispute.

Down payment and installments

The down payment is due before the installment schedule begins. Ask for it on signing: the customer pays something today, and the schedule covers the rest. Keep the number of installments small and the intervals regular. Write specific dates, not “monthly,” so both parties know exactly when each payment is expected.

The default clause

The template prints one consequence: on default, the entire remaining balance becomes due immediately. That is an acceleration clause, not a legal threat. No suit, no court, no credit-bureau language, no lien: those are claims that belong to an attorney licensed where you work, not to a fill-in template. What the default clause does keep is the connection to your original agreement, so the remedies you already negotiated apply to the accelerated balance.

Late fees point at your own terms

The late-fee section says the same thing the past due invoice letter template says: your own agreed terms govern. It prints no rate, no percentage and no statutory cap, because what you can charge comes from what the customer signed and from the law where you work. If your service agreement carries a late-fee provision (the service agreement clauses guide covers the wording), reference it. If they do not, untick the section: a fee you never agreed is a fee you will end up waiving.

After the plan is signed

Keep a copy. Note each installment date in whatever you use to track receivables (the how to get paid faster guide covers the whole sequence). If a payment arrives late but within the grace period, call and confirm rather than triggering default. If the customer stops paying altogether, the acceleration clause makes the full remaining balance due and the account is back where it was before the plan, which is where you decide whether to collect yourself or refer it out.

Everything runs in your browser. No account, no email gate, and nothing typed here is uploaded. A starting-point template only, not legal advice: payment arrangements, default provisions, late fees and collection rights vary by jurisdiction, so have a licensed attorney where you work review anything you intend a customer to sign.

Frequently asked questions

What is a payment plan agreement?

A signed document between you and a customer who cannot pay an outstanding invoice in one sum. It records the balance both parties agree on, the down payment the customer makes now, the installment dates, what happens if a payment is missed, and the late-fee terms that already apply under your service agreement. It does not create new debt: it restructures an existing balance into a schedule the customer can keep.

When should I offer a payment plan instead of sending to collections?

When the customer is willing to pay but short on cash. A payment plan collects more money than a collection agency does, keeps the customer relationship intact, and costs nothing to set up. This template is the document for that conversation: fill in the balance, the down payment and the dates, print two copies, and both parties sign. If the customer will not agree to a plan or stops paying once they do, that is when the account leaves your hands.

Should the payment plan include a late fee?

Only if your own service agreement or invoice terms already provide for one. The template includes an optional late-fee section that points at those terms and prints no rate, because what you can charge comes from what your customer agreed to and from the law where you work. Size the fee on the invoice late fee calculator first, then reference the result in the balance. If your terms carry no late-fee provision, untick that section.

What happens if the customer misses an installment?

Whatever this agreement says, which is whatever you write in the grace-period field. The default clause printed here says that if an installment is not received within the grace period and the customer has not called to agree on a new date, the arrangement is in default and the full remaining balance becomes due immediately. That is the strongest term the template will print: no suit, no court, no credit-bureau threat. If the balance reaches that point, speak to an attorney licensed where you work.

Is this legally binding?

Once both parties sign it is meant to work as a contract; whether it and each clause is enforceable depends on your jurisdiction. That is exactly why this page says it is a template and not legal advice, at the top and at the bottom. Have a licensed attorney where you work review the document before you ask a customer to sign it.
