Bank Reconciliation

Pronunciation: BANK rek-un-sil-ee-AY-shun

Definition

Bank reconciliation compares an organization's accounting cash balance with bank statements and bank transaction data. It identifies timing differences, fees, interest, returned payments, deposits in transit, outstanding items, duplicates, omissions, and unauthorized activity. Bank Reconciliation requires named ownership and auditable controls for matching evidence, cutoff control, and exception resolution. Controls should define legal and operational roles, enforce least privilege, preserve immutable postings, use approved account mappings, lock accounting periods appropriately, and reconcile by currency and cutoff.

Overview

Bank reconciliation compares an organization’s accounting cash balance with bank statements and bank transaction data. It identifies timing differences, fees, interest, returned payments, deposits in transit, outstanding items, duplicates, omissions, and unauthorized activity. Exports need versioned schemas and stable identifiers.

The operational record should capture source record, counterpart record, matching rule, cutoff, amount, currency or asset, exception reason, and resolution evidence for Bank Reconciliation, including the handoff to Reconciliation . The operating record should identify the source population, counterpart data, matching rule, cutoff, amount or value, tolerance, exception reason, owner, and resolution evidence.

Bank Reconciliation should remain distinct from Reconciliation and Reconciliation Exception, because each can represent a different stage, record, control, or financial outcome.

The failure model should include misidentified owners, excessive authority, stale balances, wrong currencies, duplicate postings, cutoff mismatches, unmapped fees, unsupported exports, unresolved suspense items, and reconciliation that hides rather than explains differences. Important failure modes include missing records, duplicate matches, timing differences, hidden fees, currency mismatches, stale files, and adjustments that force balances to agree without explaining the cause.

Controls should keep original source records immutable, use stable match keys, explain many-to-one or one-to-many relationships, and route unresolved differences to an aged exception queue. For Bank Reconciliation, the authoritative record and completion rule should be documented before any irreversible operational, customer, or accounting action is released. Teams using Bank Reconciliation should preserve the evidence behind each decision so retries, corrections, support reviews, and audits can reproduce the final outcome. Changes affecting Bank Reconciliation should be versioned, tested under normal and degraded conditions, and reconciled after incidents or manual intervention.

Key Takeaway

Bank reconciliation compares an organization's accounting cash balance with bank statements and bank transaction data. Its matching scope, cutoff, exceptions, and resolution evidence must be explicit.
