Customer Says They Paid Your Invoice, but You Haven’t Received the Money?

“We already paid.”

You check the account. No matching payment.

Before another reminder goes out, find out what the customer means by paid. The invoice may be approved, scheduled for a payment run, sent to the bank, or paid but sitting unmatched in your own books. Each situation needs a different response.

Start with four details: the amount, date actually sent, payment method, and bank or payment-provider reference.

Check your receipts before chasing the customer

Search your bank and payment-processor records, unapplied customer payments, and grouped deposits. Look by amount and date, rather than relying only on the invoice number.

If one transfer covers six invoices, ask for the allocation: which invoice numbers and how much against each? Otherwise, your team can chase six balances while the money sits unidentified.

In QuickBooks, matching links a bank transaction to the existing invoice or payment record. Verify receipt before completing the match.

Ask which step has actually happened

Use one direct question: “Has the payment been released, or is it still awaiting approval or scheduled?”

If the customer means…	Your next request
Approved internally	Who can release it, and on what date?
Scheduled for a payment run	Confirm the date, amount, and method.
Sent through the bank or payment provider	Send the payment confirmation and reference.
Received but not matched in your books	Identify the deposit and invoice allocation.

Portal labels vary. Treat a status screenshot as a starting point, then check the underlying payment records.

Request evidence someone can use

• ACH: Ask for the amount, send date, and trace number. If your bank cannot locate it, ask the customer to have their bank trace the payment. The Federal Reserve describes bank-to-bank ACH payment trace requests for checking whether an entry was received, returned, or posted.

• Wire: Request the bank confirmation, amount, date, and payment reference. Ask the sender to arrange an investigation through their bank if necessary.

• Check: Request the check number, mailing date, payee, and mailing address. If it cleared, request a paid-check image with unrelated information redacted.

Keep the original invoice number and due date. Track the investigation separately so the search for a payment does not become a fresh billing cycle.

A short email you can send today

Subject: Payment details needed — invoice [number] Hi [Name], We haven’t matched a payment to invoice [number] for [amount]. Please confirm whether payment was sent or is still awaiting approval or release. If sent, please provide the amount, send date, payment method, bank or payment-provider reference, and the invoices covered. If it has not been sent, please confirm the release date and who is authorizing it. Please copy the person who can verify these details and respond by [date]. [Your name]

Give the next action an owner and a date

A payment trace needs a follow-up date based on the bank’s guidance. A payment awaiting approval needs a named person who can release it.

Record the next action, who will take it, and when you will review the result. If repeated claims of payment produce no usable evidence or payment date, consider having the account reviewed for collections. Include the claimed payment details and your verification attempts in the supporting account file.

If the payment went to unfamiliar bank details: call a verified contact using a number already in your records. If fraud is suspected, contact the banks immediately. The FBI recommends independently verifying payment changes.
