What is bank reconciliation?
Bank reconciliation is the process of comparing your company's internal financial records — typically your General Ledger (GL) — against your bank statement to ensure they match. Any discrepancies are identified, investigated, and resolved before the period is closed.
It sounds simple. In practice, it's one of the most time-consuming, error-prone tasks in accounting.
Why does bank reconciliation matter?
Without regular reconciliation, errors go undetected. That means:
- Fraud goes unnoticed. Unauthorized transactions that don't match your GL can hide for months.
- Errors compound. A $45 bank fee not recorded in your GL becomes a growing discrepancy each period.
- Audits become nightmares. Auditors expect a clean, locked reconciliation trail. Manual spreadsheets don't cut it.
- Cash flow reporting is unreliable. If your books don't match the bank, your cash position reports are wrong.
The traditional bank reconciliation process
Most accounting teams follow these steps manually:
- Export the bank statement — download a CSV or PDF from online banking
- Pull the GL entries — export transactions from your accounting system for the same period
- Match transactions — line by line, find each bank transaction in the GL
- Investigate discrepancies — unmatched items need to be explained or corrected
- Adjust and record — book any missing entries (bank fees, interest, etc.)
- Sign off and close — document the reconciliation and lock the period
For a company with one bank account and 200 transactions a month, this process can take 4–8 hours. For companies with multiple banks and thousands of transactions, it can consume entire days — every single month.
Common types of reconciliation differences
Not every discrepancy means something is wrong. Common timing differences include:
- Outstanding checks — issued but not yet cleared at the bank
- Deposits in transit — recorded in your GL but not yet processed by the bank
- Bank fees — charged by the bank but not yet recorded in your GL
- Interest earned — bank credits not yet booked
- Errors — data entry mistakes on either side
The goal is to explain every difference until your adjusted GL balance equals your adjusted bank balance, and your variance hits $0.00.
How automation changes everything
Modern bank reconciliation software like BankRecon eliminates the manual matching step entirely. Instead of comparing transactions line by line, a rules engine automatically matches bank transactions to GL entries based on amount, date, and description.
The result: 90%+ of transactions reconcile automatically. Your team only touches the exceptions — which typically takes minutes, not hours.
How often should you reconcile?
Monthly at minimum. Most organizations reconcile at the end of each accounting period. High-volume businesses often reconcile weekly or even daily for critical accounts.
The longer you wait, the harder it gets. A 30-day backlog of unmatched transactions is manageable. Six months of backlog is a project.
Key takeaway
Bank reconciliation is non-negotiable for financial accuracy and fraud prevention. The question isn't whether to do it — it's how to do it without consuming your accounting team's most valuable time.
That's exactly the problem BankRecon was built to solve.
