Types only: no company or product is named. Step by step ## Seven steps to automate the match Work through them in order. Each step shrinks the pile the next one has to handle. 1. ### Bring bank data in automatically Use a bank feed or scheduled statement files so nobody retypes a single line. 2. ### Set matching rules Match on amount, date window and reference. Start strict, then loosen one rule at a time. 3. ### Let AI propose fuzzy matches Accept suggestions only above a confidence threshold you set. Below it, a person decides. 4. ### Route unmatched items to a person Send leftovers to one owner with the bank line and the closest ledger candidates. 5. ### Post adjustments with approval Fees, interest and corrections get a journal entry that a second person approves. 6. ### Lock the period with an audit trail Close the month so nothing changes silently, and keep who matched what, and when. 7. ### Measure close time and unmatched rate Track days to close and the share of lines needing a human, then tighten the rules. Side by side ## What reconciliation costs by hand Estimated. Replace the illustrative inputs with your own and rerun the formula. | | Value | Source and year | | ----------------------------------- | ------------------------------- | ----------------------------------------------------- | | Accounts reconciled per month | 4 (illustrative) | Your own count | | Minutes to match, per account | 180 (assumption) | Time one real month | | Minutes to review, per account | 45 (assumption) | Time one real month | | Median hourly wages before benefits | $24.36 clerk; $40.23 accountant | BLS, May 2025 | | Estimated monthly cost | About $410 before benefits | Accounts x (match x clerk + review x accountant) / 60 | ## Bank reconciliation in one paragraph Bank statement * Deposits and withdrawals * Fees and interest * Timing differences Your ledger * Invoices and payments * Entries you recorded * Items not yet cleared Reconciliation compares the bank's record of your money with your own books and explains every difference. The full definition lives in our [bank reconciliation](https://nexumautomations.com/glossary/bank-reconciliation) entry. One finance-automation vendor puts it plainly: at its core, it is a matching problem. That is why rules and AI fit it so well. ## What reconciliation costs by hand 1. Accounts Count the accounts you reconcile monthly. 2. Matching time Minutes spent pairing bank lines to entries. 3. Review time Minutes an accountant spends checking. 4. Hourly wages Multiply each by its median wage. 5. Monthly cost Add them up before benefits. Manual matching hides a real cost. Here is a transparent estimate you can rerun with your own numbers; the minutes and volume are assumptions, not measured results. Formula: accounts x (minutes to match x clerk wage + minutes to review x accountant wage) / 60. With 4 accounts, 180 minutes to match and 45 to review, the clerk costs about $73 and the review about $30 per account. That is roughly $410 a month before benefits, and it grows with every account. Outside research points the same way: Parseur's 2025 survey, run with QuestionPro, puts manual data entry at an average of $28,500 per employee each year. ## Controls that stay in place Keep these controls * Separate preparer and approver * Approval on adjustments * Audit trail on every match Drop these habits * One person posts and approves * Silent edits after close * Accepting every AI suggestion Automation changes who does the matching, not the need for control. Keep one person from both posting entries and approving them. Adjustments such as fees or corrections still need an approver, and every change should leave a trace. The audit trail is what lets you answer questions months later. Decide in advance which tasks AI may handle alone and which stay manual. Low-risk matches suit automation; unusual or large items deserve a person. * Separate preparing from approving * Approve every adjusting entry * Keep a log of who changed what * Review AI matches below the threshold by hand ## Common mistakes to avoid * Messy source data Clean names and references before matching. * Loose threshold Low confidence lets wrong matches through. * Orphan exceptions Give leftovers an owner and a deadline. * No audit trail Log every match and every change. The biggest mistake is automating a messy process. If the same vendor appears under five names, fix that first, or the rules will miss. Another is setting the AI threshold too low to chase a higher match rate. Wrong matches cost more than a leftover line. Teams also forget the exceptions queue. Without an owner and a deadline, unmatched items pile up until the close. ## When to get help Start on your own * One or two bank accounts * Clean references on payments * Low monthly volume Bring in help * Many accounts and entities * Messy or missing references * Month-end close runs late Simple setups can start inside the tools you already use. Get help when volume is high, several banks feed one ledger, or matching depends on messy references. Reconciliation sits next to invoice and payment work, so it often pairs with [accounts payable automation](https://nexumautomations.com/solutions/accounts-payable-automation).

Gather the bank statement and the ledger for the same period, match each line, list what is left, explain each difference, post any needed adjustments, and sign off the closing balance. * ### What is reconciliation automation? Software that matches bank lines to ledger entries using rules and, often, AI suggestions. People review only the exceptions instead of checking every line themselves. See [how to automate expense reports](https://nexumautomations.com/how-to/automate-expense-reports). * ### What is automated payment reconciliation? Payments received or sent are paired to invoices and bank lines automatically, using amounts, dates and references, so cleared items need no manual touch. Read about [how to automate employee onboarding](https://nexumautomations.com/how-to/automate-employee-onboarding). * ### Can AI perform bank reconciliations? AI can propose matches and flag odd items, but a person should still approve low-confidence matches and adjusting entries. Set a confidence threshold and review below it. * ### Can ChatGPT do bank reconciliation? A general chatbot can help compare small sample files, but it lacks audit trails and approvals. For monthly closes, use a controlled workflow built on your accounting data. * ### How do you decide which tasks to trust to AI? Trust it with repetitive, low-risk matching where errors are easy to spot. Keep people on large amounts, unusual items and any posting that changes the books. * ### Will automating reconciliation cut bookkeeping jobs? Software already handles many routine tasks, and the Bureau of Labor Statistics projects employment of bookkeeping clerks to fall 6 percent from 2025 to 2035. * ### What does automation do to the unmatched rate? Rules clear the obvious lines and AI suggestions cover fuzzy ones, so fewer items remain. Track the unmatched rate each month and tighten rules where it stalls. --- Source: https://nexumautomations.com/how-to/automate-bank-reconciliation Free AI diagnosis (30-minute call): https://nexumautomations.com/#book - Services: https://nexumautomations.com/services - Guides: https://nexumautomations.com/guides
