A small payment arrives but the promise covered the whole overdue balance

The receipt changes only part of the position
A hypothetical contractor is owed $50,000 and receives $2,000 after a promise to clear the account on Friday. The receipt is useful, but it does not explain when the remaining amount will arrive. Before thanking the customer for settling the account, reconcile the payment and check exactly what was promised. Keep the discussion factual and acknowledge the money actually received.
Allocate the receipt accurately
Confirm the payment has reached the correct account and identify the invoice allocation using the available records. If the customer specifies a different allocation from your ledger, resolve that discrepancy with appropriate accounting assistance. Avoid presenting an unchanged statement that ignores the receipt. Equally, do not mark the whole invoice paid because one bank entry carries its invoice number.
Ask what the customer is proposing now
Business.gov.au recommends discussing payment timing or a payment schedule when an account remains unpaid. Ask whether the small receipt was intended as an instalment and what amount and date are proposed next. A unilateral part payment is not a complete repayment agreement. Have any proposed arrangement reviewed where it could affect existing rights, security or ongoing recovery steps.

Explain the remaining amount clearly
Send a reconciled statement showing the original balance, the received payment and the amount still outstanding. In the hypothetical example, the statement would show $48,000 remaining, assuming no other adjustments. Refer to the earlier promise without accusing the customer of dishonesty. Ask them to confirm or explain the difference between that promise and what actually occurred.
Make a decision beyond another reminder
Review the response alongside the payment history, any genuine dispute and the cost of further action. A small payment may improve the cash position without making an open-ended arrangement workable. Obtain advice before accepting settlement language or threatening a particular legal step. Record who will make the next decision and which evidence they need to make it.
Keep the account status visible
Update the ledger, collection notes and cash forecast consistently. Record the receipt as actual cash and future payments as uncertain until received. CRP can help assess a sensible next step for the remaining debt. The useful outcome is a clear position on the unpaid balance, rather than allowing a small receipt to restart the same vague promise cycle.
