When the balance in your business records differs from the amount reported by a customer or supplier, the first step is to investigate the cause. Before changing entries to make the balances match, compare account transactions prepared for the same date and currency. A missing invoice, a payment recorded on a different date or a receipt posted to the wrong account can create a difference that is not immediately explainable.
When an account reconciliation discrepancy arises, the objective is to identify which transaction differs and why, make any necessary corrections using supporting documents, and confirm the outcome with the other party in writing. Following this process improves the reliability of receivables and payables tracking and helps prevent unresolved differences from carrying forward into subsequent accounting periods.
What Should You Check First When Account Reconciliation Shows a Discrepancy?
Start by checking whether the records cover the same scope. Review the reconciliation date, accounting period, business name, relevant customer or supplier account, and currency together. If transactions with the same business are tracked across several branches or account records, the parties may be comparing different sets of transactions. Also remember that an amount receivable by one party will normally be payable by the other; this difference in perspective does not indicate an error.
Next, check the opening balance and the total debit and credit movements during the period. If the amount brought forward already differs, begin the investigation there. Comparing a current statement with an older report can also produce misleading results. Both parties should therefore exchange detailed account statements using the same cutoff date, ensuring that the review starts with comparable records.
What Causes Discrepancies in Customer and Supplier Account Reconciliation?
Many discrepancies arise because the same transaction appears in the parties’ records at different times or for different amounts. Common examples include an invoice missing from one set of records, a document posted twice, a return that has not yet been processed, or a payment allocated to another account. Even correctly recorded transactions can produce different balances if activity close to the period end falls within different reporting cutoffs.
For foreign currency accounts, confusing the transaction currency with its Turkish lira equivalent, applying different exchange rates or comparing revaluation entries inconsistently can also create differences. Bank charges deducted from a transfer may mean that the amount sent differs from the amount received. When investigating an account balance discrepancy, avoid assuming there is only one cause: several missing or incorrect entries may lie behind an apparently small net difference.
How Can You Find a Discrepancy by Comparing Account Statements?
It is helpful to start from the most recent date on which both parties agreed on the balance. Match subsequent transactions using document numbers, transaction dates, amounts and currencies. Matching by date alone is insufficient because the same transaction may have been recorded on different days in the two systems. Once matched transactions have been set aside, the remaining entries provide a clearer view of the items requiring investigation.
Check whether the total difference equals the amount of a particular document, but do not treat that similarity as conclusive evidence. Several transactions may have identical values, while separate errors may partially offset one another. Adding an explanation and supporting document details beside each unmatched entry makes discussions with the other party more specific and prevents unnecessary repetition of work already completed.
How Can You Identify Reconciliation Discrepancies Caused by Invoices and Returns?
When comparing invoices, check the document number, issue date, recipient details and total amount together. If a document is absent from one party’s records, establish whether it was received and posted to the correct account. For returns, review the physical return of goods separately from the recording of the related documentation. Examine partial returns, cancelled documents and duplicate entries to identify the specific transaction responsible for the difference.
How Can You Identify Reconciliation Discrepancies Caused by Payments and Receipts?
Compare payments and receipts with bank transfer confirmations and bank account transactions. Review the sender, receiving account, transaction date, amount and payment reference together to confirm that the transfer relates to the relevant business relationship. Posting a payment to the wrong customer or supplier account, treating a partial receipt as full settlement, or overlooking bank charges can create differences. For payments covering several invoices, also check how the amount was allocated across individual documents.
How Should an Identified Account Reconciliation Discrepancy Be Corrected?
Before making a correction, clearly establish the cause, the supporting document and the entry containing the error. If a document is missing, verify its status; if there is a duplicate posting or an incorrect account allocation, examine the relevant accounting entry. The responsible accountant should assess the appropriate treatment based on the nature of the error. Where earlier periods are affected, concentrating solely on matching the current balance can leave other inconsistencies unresolved.
The correction should include a clear explanation linking the adjustment to the relevant transaction and supporting documentation. Unsupported amounts should never be posted simply to force agreement between balances. If the difference relates only to timing, assess the reconciliation cutoff alongside the date on which the transaction was recorded. Once the necessary work is complete, generate an updated statement and check that both the relevant transaction and the closing balance reflect the intended correction.
What Should You Do If the Cause of the Discrepancy Cannot Be Found?
If the difference remains unexplained, send the other party a detailed schedule of unmatched transactions rather than only the closing balance. Clearly state which documents have been checked, which entries appear to be missing and what explanations are required. Direct discussions between accounting teams can be supported by documents and information held by sales or purchasing staff. This turns a general disagreement about the balance into specific transactions that can be reviewed.
While the investigation continues, track the unresolved amount separately and assign a responsible person and a follow-up date. Communicate the disputed items in writing instead of providing unconditional confirmation of an unexplained balance. A significant amount, transactions spanning earlier periods or complex records may require a more detailed accounting review. If professional assistance is needed, prepare the statements, relevant documents and previous correspondence together so they can be assessed as a complete record.
How Should Account Reconciliation Be Confirmed After the Discrepancy Is Resolved?
Confirm the resolution using updated records prepared by both parties as of the same date. The information exchanged should clearly identify the business, relevant account, currency, balance and which party owes the amount to the other. Recheck the corrected transactions and obtain written confirmation from the people authorised to confirm the account. New transactions arising during the investigation should be kept distinct from the comparison relating to the original cutoff date.
Retain the confirmation correspondence, compared statements and documents supporting the corrections together. Use the identified cause to improve the relevant process, whether that involves document delivery, payment references or account selection. Sharing this documentation during accounting work with STB CPA Turkey can also support the assessment of discrepancies and consistent follow-up. Completing the reconciliation requires both agreement on the balances and a clear record of the transactions and corrections that explain that agreement.
