Freeze the period and source copies
Anchor the comparison to the statement closing date and retain both the issued statement and a ledger export for that account and period. Note the export timestamp, accounting basis, currency, and applied filters.
Freeze the exported ledger during matching. Enter corrections through the bookkeeping system's normal controls, then generate a fresh report after the reconciliation schedule explains why the original records differed.
Matching decision order
Resolve these questions and preserve the answers before any adjustment is posted.
Same scope
Verify that account, currency, and cutoff are identical across both records.
Same event
Confirm the event through value, direction, reference, and counterparty evidence even when dates differ.
Timing or error
Decide whether later clearance is expected or one source requires a controlled correction.
Closure
Identify the evidence that demonstrates clearance, correction, or a valid continuing outstanding status.
Match with more than amount and date
Test identity with value, direction, references, counterparty, check number, batch information, and timing. Processor settlements may combine several sales, while one invoice payment may arrive through multiple deposits.
Distinguish full, grouped, partial, and unmatched results. Any one-to-many relationship needs a component schedule whose values reproduce the bank entry.
Use grouped matching when a bank event represents multiple book entries. If 3,000 of recorded sales becomes a 2,940 processor deposit after a 60 fee, link the batch, fee, and deposit rather than forcing a false direct match. Show gross books, deductions, net bank value, dates, references, and explanatory rule to preserve revenue and fee evidence.
Support grouped matches explicitly. A processor deposit of 2,925.00 may correspond to 3,000.00 of recorded sales less 75.00 of processing fees. Link the sales batch, fee record, and net bank deposit in one match group instead of changing the book receipt to the bank amount. The group should show gross amount, deductions, net amount, dates, references, and evidence. This preserves revenue and fee treatment while explaining why no single book entry equals the bank row.
Classify the reason for each difference
Treat deposits in transit and uncleared payments as timing differences. Fees, interest, direct debits, returns, and bank corrections can require new book entries, while duplicates or entries in the wrong amount or account require controlled correction.
Never alter the issued statement or remove a ledger entry solely because no matching bank row appears. First establish whether cutoff, another account, payment failure, or entry error explains the difference.
Classify unmatched items before posting: a fee shown only by the bank may need entry in the books, a payment found only in the ledger may still be outstanding, a duplicate may need reversal, and an unexplained value may need evidence instead of adjustment. Record proposed treatment, owner, support, posting date, and account; keep temporary suspense items open until evidence closes them.
Classify unmatched items before adjusting anything. A bank-only service fee may require a book entry, a book receipt not yet on the statement may be a timing difference, and a duplicate book payment may require reversal. Record the proposed treatment, evidence, account, owner, and posting date. An unexplained suspense entry can temporarily isolate work, but it should remain on the exception schedule with a deadline. Agreement created by an unnamed plug is not a completed match.
Close and carry forward responsibly
Agreement is required between adjusted bank and book balances, with evidence behind every adjustment. Carry valid open items forward without changing their original date or assigned owner.
Age unresolved items separately. When a difference persists across periods, it may require a stop-payment decision, counterparty follow-up, or a correction made under the organization's accounting policy.
Close the period with an exception aging view. Separate items expected to clear in the next period from items needing correction or third-party evidence. For each open item, capture its first date, value, identifier, planned clearance, responsible reviewer, newest update, and follow-up deadline. When the next statement arrives, test every carried item before starting new matching work. This prevents an old outstanding payment or deposit from being copied forward indefinitely and makes later clearing evidence part of the original reconciliation record.
When a matched row represents money moving between accounts or returning from a merchant, apply the transfer, refund, and reversal handling rules before changing its category.
