Promise to pay letter template
Reviewed in November 2026
A promise to pay letter is a short signed letter in which a customer commits to pay an overdue amount by a date. Creditors ask for it when a customer cannot pay at once.
What it includes
- Date
- Creditor name
- Customer name and contact
- Amount owed in words and figures
- Origin of the debt
- Payment dates and amounts
- Payment method
- Signature
Promise to pay letter: full text
[Date] To: [Creditor name] [Address] Subject: Promise to pay I, [customer name], of [address], acknowledge that I owe [creditor name] the amount of [amount in words] ([amount]) for [origin, for example invoice number or rent]. I promise to pay this amount as follows: [date 1] [amount] [date 2] [amount] I will pay by [method] to [account or place]. If I cannot pay on a date, I will tell you before that date. ____________________________ [Customer name] [Phone] Accepted by: ____________________ Date: ____________
When to ask for it
- A customer says the payment is coming but gives no date.
- An overdue account needs a new date in writing.
- A tenant asks for a few extra days on the rent.
- A buyer needs two or three parts to clear a balance.
For a full repayment plan with many installments, a payment agreement letter fits better.
What goes in the letter
| Part | What it says |
|---|---|
| Date and parties | Who promises and to whom |
| Amount | The overdue amount in words and figures |
| Origin | The invoice, rent or fee it comes from |
| Date or dates | When the payment or payments will be made |
| Method | Transfer, cash or another agreed way |
| Signature | The customer's name and signature |
A promise to pay worked out
Liam Carter owes Bayview Gym USD 270.00 for three months of membership. He cannot pay all at once.
He signs a promise to pay USD 135.00 on 15 November and USD 135.00 on 15 December.
The gym sends a reminder two days before each date and a receipt after each payment.
How to ask for one without pressure
Ask on WhatsApp with a short message after a missed payment.
«Hi Liam, no problem about the delay. Could you confirm in writing the dates you can pay? Then I will send the reminders.»
A signed promise turns a vague «soon» into dates both sides agreed.
Common mistakes
- No date, only «as soon as possible».
- An amount that does not match the account.
- No signature from the customer.
- Changing the dates without a new letter.
Field by field
- Date and parties: the date signed, the customer's full name and the creditor. «To: Bayview Gym» opens the letter.
- Amount: USD 270.00 in figures and two hundred seventy dollars in words. Match it to the account statement.
- Origin: the invoice, rent or fee behind the debt. «Membership fees for August to October» is enough.
- Dates: one line per payment with its own amount. The lines must add up to the total.
- Method: card, transfer or cash at the front desk. Name the account for transfers.
- Signature: the customer's name, signature and a phone number. The phone lets reminders reach them.
Variants for other debts
Each version changes the main promise and keeps the rest of the letter.
- Single date: «I promise to pay the full amount of [amount] on [date].»
- Rent: «I promise to pay the rent of [amount] for [month] by [date], with next month's rent on time.»
- Supplier invoice: «I promise to pay invoice [number] for [amount] in two parts on [date 1] and [date 2].»
- Promise note to pay a loan: «I promise to repay the loan of [amount] received on [date] by [due date].»
A second example from the Philippines
Ronaldo owes a water refilling station in Laguna PHP 4,800.00 for deliveries.
He signs a promise to pay PHP 2,400.00 on 15 and 30 November.
The owner keeps the letter and sends a text two days before each date.
Ronaldo pays both parts and gets a receipt each time.
The owner writes «paid in full» on the letter after the second payment.
Ronaldo keeps a photo of it in case a question comes up later.
The station keeps delivering water to him on the same terms.
When the promise is broken
Send a reminder the day after the promised date passes.
«Hi Liam, the USD 135.00 planned for 15 November has not arrived. Could you send a new date?»
Agree the new date in writing and update the letter if the plan changes.
After two broken dates, move to a collection letter with the full balance.
Keep the signed letter with the messages. Together they show what was agreed.
A message to confirm the signed letter
«Hi Liam, thank you for the signed promise to pay. The dates are 15 November and 15 December for USD 135.00 each. I will send a reminder two days before.»
Send it the same day so both sides hold the same dates.
Promise to pay letter or payment agreement
| Point | Promise to pay letter | Payment agreement letter |
|---|---|---|
| Who signs | The customer only | Both parties |
| Number of dates | One to three | Often many installments |
| Typical amount | Small overdue balances | Larger debts |
| Extra terms | Few or none | Fees, default and settlement terms |
Start with the letter for a short delay. Move to an agreement for a longer plan.
