Foreign supplier reconciliation: check invoices, payments and open balances

GURI Journal · Published 31 October 2026
A supplier's statement and the buyer's ledger can show different totals without immediately revealing which figure needs correction. The reports may cover different dates, currencies or accounts. A payment may be allocated differently, or a credit may appear on one side only. Reconciliation begins by defining what is being compared before deciding how a difference should be treated.
GURI approaches the review as a traceable explanation of the account. Each material amount should connect to the relevant transaction and supporting records. The exercise supports accounting decisions; it does not replace the professional assessment of recognition, currency translation or tax treatment under the entity's applicable rules.
Match the parties and the reporting boundary
Confirm the legal supplier, buyer, account reference, currency and statement date. A trading name may differ from the legal entity, while one supplier may maintain separate accounts for branches or contracts. Clarify the relationship rather than matching records solely because the names look similar.
Use the same cut-off for the comparison or explicitly bridge the difference. A statement prepared before the latest payment will naturally differ from a current bank report. Keep the dates visible so that a timing difference does not become an unexplained balancing adjustment.
Check whether the supplier statement and internal report include the same types of items. One may show invoices and credits, while another includes payments awaiting allocation. Understand the report definitions before concluding that an amount is missing. Similar column headings do not guarantee identical content.
Establish the opening position
Obtain the previous reconciliation and the items making up the opening balance. Mark unresolved differences carried forward. Treating an unexplained beginning figure as confirmed can make every later calculation appear consistent while preserving the original problem.
Where historical information is incomplete, state the limitation and agree the necessary follow-up. Do not manufacture an opening adjustment simply to make the new period balance. The responsible accountant needs the available evidence and context to determine the appropriate action.
A simple hypothetical movement can illustrate the arithmetic. An opening payable of 1,000 units, additional invoices of 600 and allocated payments of 900 would leave 700, assuming no other items. This is only a movement check. It does not prescribe ledger entries, tax treatment or foreign exchange calculations.
Match documents before matching totals
Compare invoice references, dates, original currency amounts, order numbers and any credits or returns. Confirm that the documents refer to the intended goods or services. Similar amounts alone are a weak basis for matching, particularly where recurring orders have the same price.
Look for duplicate delivery of the same record through different channels. An invoice emailed by the supplier and later uploaded by a colleague should not be mistaken for two separate events. Equally, a corrected document must remain connected to its earlier version so that the team understands what changed.
Check goods and service evidence where relevant to the question. An invoice, receipt record and bank transaction may describe different stages. The accountant needs the actual sequence and supporting information to assess the entries; the reconciliation should not collapse every stage into the word paid.
Trace how each payment was allocated
One transfer may settle several invoices, and one invoice may be settled in instalments. Obtain the allocation information and compare it with the supplier's records. An account total can agree even when individual orders are incorrectly marked as complete.
For example, a hypothetical payment intended for two shipments might be assigned entirely to the first. The total cash movement remains unchanged, but the order-level picture is wrong. The review should identify the intended and recorded allocation, then send the difference to the person authorised to resolve it.
Separate the amount instructed, the bank movement and the amount the supplier confirms as received where those differ. Fees, timing, currency conversion or a partial payment may be relevant, but none should be assumed without evidence. Ask for the records needed to establish the cause.
Keep original currency and translated amounts distinct
Start the transaction comparison with clearly labelled original amounts, then examine translated figures using the applicable accounting basis. Record the relevant dates and the source of any rate already used. A converted management total may answer a different question from the supplier's statement.
The IFRS Foundation describes IAS 21 as addressing foreign currency transactions and the reporting effects of exchange-rate changes. Where IFRS applies, the entity must assess the relevant requirements; a difference between two figures should not automatically be labelled an exchange difference.
Other reporting frameworks or local obligations may require their own assessment. The review should preserve enough information for that decision rather than forcing all records into a single convenient conversion. If the basis is unclear, identify it as a question for the accountant.
Build an exception list with a next action
For each unresolved item, record the amount, currency, affected document, observed difference and evidence required. Assign an owner who can obtain the information or make the decision. A general note saying “awaiting supplier response” is unhelpful when nobody knows which document was requested.
Distinguish missing evidence, a factual error and a matter of accounting judgement. They require different responses. The purchasing team may explain an agreed price reduction; the supplier may need to provide a corrected record; the accountant may need to assess how the confirmed facts should be reflected.
Do not alter source documents to make them agree. Keep the original material and follow the appropriate correction process. The resulting record should show why a change was made and who approved it, especially where the information has already been used in other reports.
Close the review without hiding remaining uncertainty
After agreed corrections, check the affected balances and relevant reports. Preserve the reconciliation, supporting references and unresolved items that remain outside the completed scope. A supplier's confirmation is useful evidence, but an agreed total does not by itself explain every transaction within it.
Tell the people using the figures what changed. Purchasing, finance and management may hold separate schedules, and correcting one system does not automatically update them all. A useful reconciliation leaves the business with an explainable balance, a clear list of remaining questions and a dependable starting point for the next period.
