A supplier asks about an unpaid invoice. Your accounts payable team says the transfer has already been made. Sending the same screenshot again may not resolve the query: the supplier could be looking for the transfer, or could already have the money but lack the information needed to apply it to the right invoices. Establish which question remains open before asking either team to repeat its work.

Amazon Business's October 27, 2026 announcement describes invoice allocation, payment scheduling and issue resolution as separate tasks for its payment assistant, with the user retaining control. The described features are limited to Amazon Business customers in the United States. This is not evidence that the tool is available for every international supplier relationship; it highlights a distinct administrative task that a transfer alone does not complete.

Tell the supplier what the payment covers

A transfer reference helps locate money. An invoice allocation explains what that money pays for. The two can travel in the same remittance advice, but they answer different questions. Where your company pays several invoices together, the supplier needs the relevant invoice numbers and the amount assigned to each, rather than only the total transferred.

The reverse situation matters too. An invoice may be paid in instalments, so a transfer smaller than its face value is not automatically an unexplained short payment. The supplier needs to understand whether this is an agreed instalment, a payment against several items, or an amount that still requires investigation. Those are different conversations, and the invoice balance should not be altered simply to remove a discrepancy.

Before requesting a correction, compare the payment details held by both sides. Check the currency, payer identity and references, then identify any charges or deductions that need explanation. An explanation does not by itself establish that a deduction was agreed. The people authorised to approve commercial adjustments still need to decide how the amount should be treated under the actual arrangement.

Avoid matching a payment solely because its amount resembles an open invoice. Repeated orders and similar values make that shortcut unreliable. A plausible match can clear one invoice while leaving another incorrectly overdue. Ask the paying team for the intended allocation and have the supplier confirm it against the funds it has actually received.

When checking records, retain the relationship between shipment facts and their documents. Matching totals by changing an unsupported field can hide the original discrepancy rather than explain it.

Find the person who can answer the remaining question

The buyer who placed the order may not control the payment run. Equally, the supplier's salesperson may not be able to see bank receipts. Copying more people into an email does not identify the missing fact. State whether the query concerns receipt of funds, allocation to invoices or a disputed balance, and direct it to the team with access to that information.

If the supplier cannot find the transfer, provide the payment date, payer and transfer reference through an established secure channel. Share only the information needed for the check. If the receipt has already been located, move on to the allocation detail instead of asking the buyer to prove that a transfer was initiated for a second time.

The supplier's response should be just as specific. “We received the remittance advice” does not mean “we received the funds.” “Funds received” does not necessarily mean every invoice in the payment run is settled. A useful reply identifies what has been confirmed and what is still being checked, without turning an administrative delay into an accusation that the buyer has not paid.

After the allocation is confirmed, make the remaining balance understandable. Explain whether it belongs to a different invoice, a later instalment or an unresolved difference. Keep an unmatched amount visible as unmatched until there is enough information to assign it. Quietly choosing an order can make the immediate query disappear while creating a harder one for the next payment run.

Finally, do not assume that resolving the invoice automatically authorises shipment. Release conditions, order requirements and internal authority still depend on the actual agreement. A payment screenshot should not trigger a shipping promise, and an allocation query should not be presented as proof that no money was sent. The practical objective is narrower: let both finance teams identify the same payment and agree which obligations it has satisfied.
