Every collector knows the call. You phone about an overdue invoice and the customer says, “We will pay on Friday.” You thank them, hang up and move on to the next account. Then Friday passes, nothing arrives, and nobody remembers exactly what was said. A promise to pay is only useful if it is recorded, checked and acted on. This guide explains what a promise-to-pay is, how to log it and what to do when it is broken.
What is a promise to pay?
A promise to pay (PTP) is a commitment from a customer to pay a specific amount on or by a specific date. It usually comes from a phone call, an email reply or a message from the customer’s accounts payable team. It is not a payment, and it is not a legal agreement. It is a short-term, good-faith commitment that turns a vague “soon” into a date you can measure.
That distinction matters. A PTP gives you a reason to wait a few days without escalating, and it gives you a clear point at which to act if the money does not arrive.
What a good PTP record contains
A note like “customer will pay soon” is almost useless. Capture the details that let anyone on the team pick up the account:
- Amount. The exact sum promised, and which invoices it covers. Partial promises are common.
- Date. A specific day, not “next week”. If the customer is vague, ask for a date.
- Who promised. The name and role of the person, and whether they can actually release the payment.
- Payment method. Bank transfer, card, cheque or direct debit, because it affects when funds arrive.
- Context. Any reason for the delay, such as a missing purchase order or a dispute on one line.
- Source and date logged. Whether it came by phone or email, and when.
How to log a PTP step by step
- Confirm the amount, date and method before you end the conversation.
- Record it on the customer account the same day, against the specific invoices.
- Send a short written confirmation: “Thank you for your call. We understand that $4,200 for invoices 1042 and 1051 will be paid by bank transfer on 21 October.”
- Set a follow-up reminder for the day after the promised date, not before it.
- Pause further dunning on those invoices until that date, so the customer is not chased while keeping their word.
Writing the confirmation is the step most teams skip, and it is the most valuable. It creates a shared record and gently signals that you will be checking.
How to follow up
Check on the day
Look at your bank or ledger the morning after the promised date. Funds can take a day or two to clear, so confirm whether the payment is pending or simply absent.
Keep the tone factual
If the money is not there, avoid accusation. “We expected the payment on the 21st and have not yet received it. Can you confirm it has been sent?” is firm and polite, and often reveals a simple cause such as a missed approval.
Ask for proof
If the customer says it was paid, ask for a remittance advice or a transfer reference. That settles the question in minutes.
What to do when a promise is broken
Some promises will be missed. The response should be proportionate and quick, ideally within one working day.
- Contact the same day. Ask what happened and request a new date. One missed promise is often a process delay, not bad faith.
- Look for the real blocker. Approvals, wrong invoice details, a dispute or a cash flow problem need different answers.
- Accept a smaller payment. A partial payment now with a firm date for the rest is better than nothing.
- Escalate after a second break. Involve a manager, call a more senior contact or move the account to a firmer reminder stage.
- Record the pattern. Note each broken promise. Two or three on the same account is a risk signal that may justify tighter terms or a credit hold.
Common mistakes
- Accepting vague dates. “Early next week” cannot be tracked.
- Not writing it down. Notes in your head or a personal notebook disappear when you are on leave.
- Following up too early. Chasing before the promised date damages goodwill.
- Following up too late. Waiting a week turns a small slip into a habit.
- Treating every customer the same. A reliable payer with one slip deserves a different tone from a repeat offender.
Measuring how well PTPs work
Two numbers are enough to begin. The PTP kept rate is the share of promises that were paid in full by the promised date. The PTP value kept is the same measure weighted by amount. If your kept rate is low, customers may be promising just to end the call, which is a sign to ask for firmer commitments. Review them monthly by collector and by customer segment.
A spreadsheet can handle this for a small ledger. Once you have dozens of open promises, reminders and history are easier in a tool built for it. FulcrumGrid Collection lets you log a promise against an invoice, schedules the follow-up for the day after, pauses reminders in the meantime and keeps a record of broken promises per customer. It will not make customers pay, but it stops promises from slipping through the cracks.
The principle is simple: get a specific date, write it down, confirm it in writing and check on time. Do that consistently and a promise to pay becomes a reliable signal rather than a polite delay.
Frequently asked questions
Is a promise to pay legally binding?
Usually not on its own. It is a good-faith commitment, not a contract. It still matters as evidence of the debt and of your attempts to collect it, so keep a written record.
How long should I wait for a promised payment?
Check the morning after the promised date. Allow a day or two for bank clearing if the customer says it was sent, and ask for a transfer reference to confirm.
Should I accept a partial promise to pay?
Generally yes, if it comes with a firm date for the remainder. Log each part as its own promise so you can follow up on both.
What is a good PTP kept rate?
It varies by industry and customer base, so compare against your own history first. A rate that falls over several months is a sign to ask for firmer dates or review your reminder process.
