Why Your International Payment Arrived Short—and Whether to Top Up

Your supplier reports a short payment. Your wire transfer confirmation shows the full invoice amount. Before approving a top-up—or treating the confirmation as proof that nothing is owed—consider that both can be right.

The confirmation may show what you instructed, while the supplier is reporting what reached its account. Resolving the difference means answering two distinct questions: what happened to the money, and who agreed to bear the cost? Finding a deduction answers the first. It does not automatically answer the second.

Start with the invoice, not the bank debit

There are four figures to keep separate: the amount and currency required by the business agreement, your total account debit, the payment amount instructed, and the recipient’s actual credit. They need not all match, even when the payment has been handled as instructed.

Consider a hypothetical supplier invoice for USD 10,000, payable in USD. Your account is debited USD 10,025: the payment principal plus a USD 25 sending fee charged separately. Your confirmation records an instruction for USD 10,000. The supplier’s account record shows USD 9,970 credited.

The potential invoice shortfall is USD 30—not the USD 55 difference between the two account entries. The separately paid USD 25 increased your cost without reducing the payment principal. Whether the remaining USD 30 is still payable to the supplier depends on the agreement about charges.

Currency matters just as much. A debit in your home currency and a credit in the supplier’s currency cannot be compared as though they were the same unit. The starting point is the amount owed on the agreed currency basis, not the difference between two account balances.

For fees, location matters more than the total

International payment fees explain a short receipt only when you establish how they were collected. A fee charged to you outside the principal makes the transfer more expensive. A fee deducted from the principal reduces what arrives. A fee charged separately to the supplier after a full credit reduces its cash, but presents a different reconciliation question: reimbursement of a charge rather than missing payment principal.

In the hypothetical transfer, evidence that USD 30 was withheld from the principal would explain the USD 9,970 credit. The net credit alone, however, does not identify which institution took the amount or establish whether the charge was expected.

OUR and SHA bank charges are relevant because they describe the intended allocation of transfer costs. OUR is intended to place charges with the sender; SHA shares costs between sender and recipient. Check what your bank’s option actually covers, particularly its treatment of intermediary bank fees. Do not treat an OUR label as a universal guarantee of the final net credit.

Nor does a charge instruction rewrite your supplier agreement. Selecting SHA does not, by itself, establish that the supplier accepted a smaller receipt.

A conversion difference is not necessarily a deduction

Currency conversion can produce a disappointing receipt without any money being withheld as a fee. The question is what was fixed: the invoice-currency amount, an exchange rate, or the amount the recipient was to receive in another currency.

Suppose, as a variation on the example, the supplier receives the full USD 10,000 and then converts it into its local currency. A lower local-currency value than it expected does not, by itself, establish underpayment of the USD invoice. If you instead agreed to deliver a fixed local-currency amount, that amount becomes the relevant benchmark.

Where conversion happens before the account credit, establish the amount converted and the applicable rate. Do not infer a missing deduction solely from the final balance.

An earlier calculator result is not necessarily a payment commitment. Check whether a rate or recipient amount was actually fixed for this transfer. If a rate guarantee depended on funding by a deadline, check whether that condition was met. This separates a genuine failure to deliver an agreed amount from an expectation based on a quote that no longer applied.

The confirmation is evidence, not the verdict

Read the confirmation for what it actually says happened. An accepted instruction, a sent payment and a recipient-bank credit are different milestones. A transaction reference and instructed amount help identify and trace the payment; they do not, on their own, prove the recipient’s final net credit.

Tracking information can add processing-stage evidence, potentially showing progress through an intermediary or payee bank. It should not be assumed to itemise every downstream deduction.

The supplier’s account record answers a different question: what was actually credited, and in which currency? Ask for the relevant payment entry and any associated fee or conversion entries, rather than just the account’s current balance. A balance alone can conceal the distinction between a reduced credit and a full credit followed by a separate charge.

Compare those records using the payment reference, amount and currency. If the difference remains unexplained, ask the sending bank to reconcile the instructed amount with the reported credit and identify any deductions it can substantiate. The combined records may narrow the cause without revealing every institution’s contribution.

Whether to top up depends on the promise you made

If you agreed that the supplier would receive the full invoice amount, with you bearing delivery charges, the verified USD 9,970 receipt leaves USD 30 to resolve in the example. A full sending instruction does not close that gap.

A deduction inconsistent with what your bank agreed to cover should also be questioned with the bank. But that is a separate issue from the supplier obligation: raising a bank-fee query does not itself settle a shortfall you agreed to cover. You may need to make the supplier whole while pursuing the charge separately.

If the supplier agreed to bear the relevant downstream charges, a deduction consistent with that allocation may not require a top-up. The useful response is a reconciliation showing the instructed amount, actual receipt and agreed charge treatment—not simply another copy of the confirmation.

If the difference comes from an unpromised conversion expectation, correct the benchmark rather than automatically funding it. If the agreement is silent or ambiguous about charges, banking records cannot resolve that ambiguity. Agree how to treat this payment and record whether any additional amount settles an invoice balance or reimburses a fee.

Finally, check how a corrective payment will be charged. Sending another USD 30 through a route that deducts charges from principal may leave another residual balance. The aim is to settle the agreed obligation, not merely to issue a second instruction for the apparent difference.

Conclusion

The right response is not automatically to pay again or reject the request. Establish the credit on the agreed currency basis, then apply the agreed allocation of costs. For future cross-border business payments, make that allocation explicit before choosing the bank’s charge option.
