What is bank reconciliation?

Matching GL cash to bank statements, clearing timing differences, and investigating breaks. Unreconciled cash means revenue, expenses, and tax balances cannot be trusted.

How often should you reconcile?

Monthly at minimum, weekly for high-volume or fraud-prone accounts. Daily feed review plus monthly signed rec is best practice.

What causes differences?

Outstanding checks and deposits, bank fees and interest, duplicates, FX, intercompany transfers, and posting to wrong accounts.

Preparer plus independent reviewer. No one reconciles their own disbursements without oversight.

Bank Reconciliation Guide 2026: How to Reconcile Cash in 20 Minutes Without Errors

Why Cash Comes First

If cash is wrong, every flux, covenant, and tax return inherits the error.

Use this with Month-End Close, Bookkeeping Software, and QuickBooks vs Xero.

20-Minute Workflow

Pull statement; confirm feed completeness.
Match automatically; manually match only with support.
Clear outstanding >30 days — follow up, do not auto-write-off.
Post fees/interest to correct accounts with support.
Reconcile payroll clearing to Payroll Guide.
Attach statement + rec + discrepancy log; sign and date.
Reviewer signs; lock period.

Document per Audit Procedures: who, when, support, conclusion.

Error Fixes

Symptom	Fix
Duplicate feed	Break link, delete duplicate, re-match with support
Wrong account	Journal with reason, re-rec both accounts
Stale outstanding	Investigate, reissue or accrue, never plug
FX break	Revalue at close rate, tie to FX Hedging memo

Link patterns to Fraud Prevention and Occupational Red Flags.

KPIs

Days to rec (target WD-1)
Outstanding >30 days (target zero)
Post-close adjustments (target declining)

Report to Audit Committee quarterly.

Worked Example: The $18,400 Duplicate That Rec Discipline Catches

March: vendor paid $18,400 by ACH; AP clerk re-enters the invoice (different invoice number typo) and pays again by check. April bank rec shows an uncleared $18,400 check aging past 30 days with no support. Investigation (same vendor, same amount, 6 days apart) → duplicate → stop-payment + recovery. Without monthly rec discipline, this surfaces at year-end as a stale outstanding, written off or — worse — re-paid a third time. The control is boring and total: every outstanding item over 30 days gets a named owner and a date, reviewed by someone who didn’t post it.

Multi-Account and FX Operations

Situation	Practice
5+ operating accounts	One rec per account, one reviewer summary page with all balances tied to GL cash
Payroll clearing	Must zero monthly; non-zero means unposted payroll or duplicate — see Payroll Year-End
Intercompany cash	Confirm both sides same day; breaks investigated, not netted — see Related Party
FX accounts	Revalue at close rate, book gain/loss with memo tying to FX Hedging policy
Merchant/processor clearing (Stripe, etc.)	Reconcile payouts to sales reports gross-to-net (fees separated), not net-to-net

Stripe-style netting is the modern outstanding-item swamp: gross sales, fees, refunds, and reserves all collapse into one payout. Reconcile the payout report line-by-line monthly; auditors sample these accounts precisely because companies don’t.

Fraud Patterns the Rec Exposes

Round-dollar outstanding checks to unfamiliar payees, never clearing — shell-vendor candidates. Cross-check against Occupational Red Flags.
Voided checks that cleared — segregation failure; voids require independent approval and bank confirmation — see AP Fraud.
Deposits in transit that never land — classic lapping indicator; trace to validated deposit slips immediately.
Recurring “bank error” adjustments without bank letters — demand the letter; banks document their errors.

Escalate via Whistleblower channels when patterns involve personnel, and report themes to the Audit Committee.
