Proof of Payment: What a Useful Receipt Should Show
What to include on payment receipts for cards, checks, cash, bank transfers, partial payments, and client account records.

A client sends a screenshot that says money left their bank. Your account does not show it. Another client paid cash and now nobody remembers which invoice it covered. Proof of payment is strongest when it connects a settled transaction to a specific balance, not when it merely shows that somebody clicked Send. Issue a receipt after funds are confirmed. It should name the payer, invoice, amount, date, method, and remaining balance, while keeping sensitive payment data out of the document.
Wait for the Right Kind of Confirmation
Card approvals, ACH submissions, and transfer screenshots may appear before settlement. Use the processor or bank status that your accounting process treats as received. Cash and cleared checks can be recorded directly, with check number or a limited method reference when useful. Do not include full account or card numbers. If a payment later reverses, keep the receipt history and mark the reversal rather than deleting evidence that the first event occurred.
Connect the Receipt to the Invoice
Show invoice number, payment amount, payment date, method, and balance after payment. For a partial payment, the receipt should say exactly how much remains and keep the invoice open. When one payment covers several invoices, list the allocation or attach a statement. 'Payment received, $2,000' is not enough when the client has four open balances. The connection is what makes the receipt useful to a bookkeeper months later.
Handle Cash With Two Records
Give the client a receipt immediately and record the cash in your own ledger or point-of-sale system before it leaves the work site. Use sequential receipt numbers. If an employee accepts cash, the handoff to the office should be documented too. Cash disputes are difficult because there is no bank trail, so the routine must create one. A photo of a handwritten note may help temporarily, but a duplicate receipt in the client account is much stronger.
Keep Processor Screenshots Out of the Main Record
Screenshots can help investigate a missing transfer, but they are easy to edit and may expose personal details. Ask for the transaction reference, date, amount, sender name, and originating institution, then verify through your own bank or processor. Once confirmed, issue your receipt. The client's screenshot does not become your official receipt, and your receipt should never promise final settlement while the money is still reversible under the payment method.
Send Receipts Automatically After Settlement
A prompt receipt reduces 'did you get it?' messages and gives the client a clean file for bookkeeping. Automation should follow the settled event, not merely the payment attempt.
Frequently asked questions
Is a bank screenshot proof that I was paid?
It is evidence that a transaction may have been initiated, not confirmation that funds settled in your account. Use the reference to investigate, then issue a receipt when your bank or processor confirms payment.
Do partial payments need separate receipts?
Yes. Each settled payment should have a record showing the amount applied and balance remaining. The invoice stays partially paid until the full balance is settled or formally adjusted.
