A payment plan agreement restructures a debt that already exists — an unpaid invoice, a personal loan gone overdue, money owed for work already done — into a defined schedule of installments, with an acceleration clause that makes the whole balance due if a payment is missed.

This document is a general-purpose template provided for information only. It is not legal advice, it does not create a lawyer–client relationship, and nobody has reviewed it against your situation.
Laws differ by country, state and province, and they change. A clause that is standard in one place can be unenforceable — or illegal — in another. Terms that are ordinary between two businesses can be void in a consumer or employment context.
Read every clause before you use it, fill in every blank, and delete anything that does not apply. For anything high-value, unusual, or that you could not afford to lose a dispute over, have a qualified lawyer in your jurisdiction review it before it is signed.
Creditor & debtor names and addresses
Full legal names and addresses for both the party owed money and the party who owes it.
Acknowledgment of the existing debt
What is owed, how much, and where it came from — an unpaid invoice, an informal loan, goods or services already delivered. This is the recital that makes the debt undeniable later.
Installment schedule
The number of payments, the amount of each, and the exact due dates — not a vague "in installments," but a schedule someone can check a payment against.
Acceleration clause
The clause that gives this document its teeth: if a payment is missed, the entire remaining balance becomes due immediately, not just the missed installment.
Late fee
A fee for a late installment, separate from — and smaller than — the consequence of a full default triggering acceleration.
Effect on the original obligation
A clause stating this agreement replaces the old payment terms without releasing other rights or duties under the original deal (a warranty, an indemnity, a performance obligation unrelated to payment).
Governing law
Which state or jurisdiction's law governs the agreement if a dispute over it ends up in court.
Signatures & date
Both the creditor and the debtor sign and date it — the acknowledgment of the debt is only worth as much as the signature confirming it.
A payment plan agreement and a loan agreement solve two different problems, even though both end in a repayment schedule. A loan agreement is for new money: a lender hands funds to a borrower today, and the document sets the terms that new debt is repaid under. Nothing is owed until the document is signed and the money moves.
A payment plan agreement starts from the opposite situation — the debt already exists. Maybe it’s an invoice a client hasn’t paid, a favor between friends that turned into an informal loan now overdue, or a balance owed for goods or services already delivered. Instead of originating a new obligation, the document recites the existing one — what’s owed, why, and as of what date — and then converts a demand for payment in full into a defined schedule of installments. That recital matters: it is the clause that pins down the amount so it can’t be disputed later, and it is what gives the creditor something to fall back on if the new schedule isn’t followed.
That is also why the acceleration clause carries so much weight here. A creditor who agrees to installments is giving up the right to demand immediate payment — the acceleration clause is what gets that right back the moment a payment is missed, rather than leaving the creditor to chase each installment separately as it comes due. If you’re originating a brand-new loan instead of restructuring one that already exists, use a loan agreement or promissory note — this template assumes the debt is already there.
