What it means
A customer tells the collections team it will pay an overdue invoice next Friday. The date is useful for a cash forecast, but only if the amount, account and terms are recorded and the promise is later checked against actual receipt, and customer payment promise reliability measures that follow-through.
Resolut describes the operational value and limitations of a recorded promise to pay and OpsDog describes a kept-promise percentage, but the precise grace period and amount threshold must be set locally, and a casual statement is not the same as a verified payment. Define a qualifying promise by recording the customer, invoice or account, amount, expected date and source of the commitment, and exclude vague "soon" notes.
Set the checkpoint by deciding whether payment must arrive by the stated date, a permitted grace day or the end of the agreed week, and state the choice. Set the amount rule too, since a small partial payment may not satisfy a promise to clear the whole balance, so track partial fulfilment separately.
Use bank or ledger evidence, because a customer confirmation or screenshot does not prove settled cash, and reconcile receipts and returned payments. Match remittances, as an unapplied receipt may have arrived but not been linked to the right invoice, so investigate before calling the promise broken.
Check payment method and holidays, since bank transfers, card settlements and cheques have different clearing times and a promise for a banking holiday may settle next business day, so use a consistent receipt date convention and local banking calendars. Avoid duplicate promises, because a collector might record multiple updates on the same invoice, so keep the history but prevent denominator inflation, and track changed commitments by retaining both versions if a customer genuinely renegotiates a date before the first one passes and defining which promise is scored.
Segment by customer, since a few large accounts can dominate cash impact while many small accounts dominate a simple count, so show amount-weighted context. Consider dispute status, as an unresolved quality complaint or billing error may explain nonpayment and a promise score should not replace dispute resolution.
Avoid coercive use: collections practices and debt rules vary by country, and customers should not be pressured into promises they cannot keep merely to lift a contact metric. Review collector incentives, since rewarding the number of promises can create low-quality commitments, so pair the measure with kept-rate and customer-treatment checks.
Trace root causes, because repeated broken promises can signal affordability, a disputed invoice, unclear terms or poor collector documentation. Distinguish paid late, since a promise missed by one day but paid later is not identical to an account that never pays, so track recovery timing as well, and measure by age, because promises against invoices 10 days overdue may differ from those 180 days overdue.
Use a fair denominator by counting all qualifying commitments due during the period, not only those that were paid or contacted again, and report uncertainty by classifying outcomes as pending if bank feeds are delayed. Compare forecasts and link to credit policy carefully: promise-to-pay records can inform expected receipts when historical reliability is applied, and persistent nonpayment can affect credit limits or order holds subject to contract and fair-treatment rules, but a metric alone should not trigger a block; for an owner, reliability makes collection dates more credible and cash forecasts more useful, managed with evidence and respectful customer contact.
In practice
Real-world examples.
Example
A customer promises $10,000 by Friday, and the settled amount arrives on Friday: the promise qualifies as kept. The collector checks the bank record, not the customer's message. The result is added to the month's kept count.
Example
A $1,000 partial receipt does not meet a $10,000 full-payment promise under a strict amount rule. The collector records it as partial fulfilment and agrees a new date for the balance. Both the original and the new promise stay in the history.
Example
A disputed invoice is flagged separately instead of treated as unexplained nonpayment. The customer says the delivery was incomplete. The promise is paused while the dispute is resolved, and the reason is visible in the report.
Formula
Calculation
Kept-promise rate = qualifying promises due and met under the policy / all qualifying promises due x 100. Also show amounts and late recoveries.
Worked example. A fictional collections team records 60 qualifying promises due in a month, and 42 are met under the agreed date and amount rule.
- Kept-promise rate = 42 / 60 x 100 = 70%.
- By value, the 60 promises total $300,000 and $195,000 arrived by the stated dates, so amount-weighted rate = $195,000 / $300,000 x 100 = 65%.
- A further $45,000 arrived within seven days after the due dates; this is reported as late recovery, not as kept, so $195,000 + $45,000 = $240,000 was collected in total.Case study
Seen in the real world.
This entirely fictional example follows Seabrook Supplies. Collections recorded payment dates on 60 invoices, then matched promised amounts to bank receipts. Only 42 met the defined deadline, and many misses came from invoices in dispute. Seabrook fixed invoice errors and adjusted its cash forecast rather than pressing staff to collect more unreliable promises.
The case does not describe a legal collection method for any jurisdiction. In the following quarter the kept rate improved as invoice errors fell, and the finance team applied the historical rate to its forecast of promised receipts. It still treated each promise as an estimate rather than guaranteed cash. Seabrook is an invented company, and the figures are for illustration only.
Watch out
Common mistakes.
- Treating a customer's message as settled cash without bank evidence.
- Counting repeated updates on one commitment as separate successful promises.
- Rewarding the number of commitments without checking whether they were reasonable and kept.
Questions
People also ask.
Does a partial payment count as kept?
Only if the stated policy and actual promise allow it; report partial fulfilment separately.
What if a date changes?
Retain the original and revised commitments and apply a consistent scoring rule.
Can promises be used in a cash forecast?
Yes, with evidence and an allowance for historical reliability, not as guaranteed receipts.
