BANK RECONCILIATION SOFTWARE
Bank reconciliation software checks that your books match your bank. ZeraBooks reconciles every account month by month as soon as a statement is uploaded: the statement must add up, follow the previous statement, and agree with the ledger. When a month doesn’t tie, AI re-reads the statement and proposes the fix for you to apply.

DEFINITION
Bank reconciliation is the process of comparing a business’s accounting records with its bank statement for the same period, explaining every difference, and correcting the books so the ledger balance for the account matches the closing balance the bank printed.
HOW A MONTH TIES
Every statement prints an opening and a closing balance. If every transaction between them is in your books, the numbers must agree.
Opening balance plus every transaction on the statement equals the closing balance printed on it.
This statement’s opening balance matches the previous statement’s closing balance, so nothing went missing between statements.
The ledger balance for the account equals the closing balance printed on the statement.
Try it on your own documents. One-week free trial, both apps included.
HOW IT WORKS
THE TIMELINE
Reconciliation runs as soon as a statement is uploaded. Each account gets one row and each month one dot: tied, needs a look, not covered by any statement, finalized, or reopened because its numbers changed after sign-off. Bank accounts and credit cards both reconcile, month by month.
How reconciliation works
FIND THE DIFFERENCE
A month that doesn’t tie opens on three tiles comparing the statement and the ledger: deposits, withdrawals and net (payments, charges and net for a card). Flags name the cause: a statement that doesn’t add up, a chain break, a ledger difference, a coverage gap, or a payment that may be counted twice.

AI VERIFICATION
Click Verify against the document and ZeraBooks transcribes the original statement line by line and compares it with your rows. It proposes only fixes that make the statement tie, each quoting the line it’s based on: a missed or phantom line, a flipped sign, or a misread amount, date or balance. You apply them with one click.

SIGN OFF AND CLOSE
Sign off each month that ties, then close the books through it so nothing reconciled can change by accident. If a finalized month’s numbers change later, it’s marked reopened for review. With Autopilot on, tied months can be signed off and closed for you.

IN A SPREADSHEET
The manual method, for one account and one month.
Put the bank statement’s transactions in one table and your ledger’s transactions for the same account and month in another.
Tick off every item that appears in both, matching on date and amount.
Deposits in transit and uncleared checks are in your books but not yet on the statement.
Statement closing balance plus deposits in transit minus outstanding checks should equal your ledger balance.
Record bank fees, interest or errors that appear only on the statement, then check that the two balances agree.
SOFTWARE VS SPREADSHEET
| Feature | ZeraBooks | Excel or a manual tick-off |
|---|---|---|
| How a month is proven | Three checks against the printed balances | Line-by-line matching |
| Missing statements | Chain breaks and coverage gaps are flagged | Easy to miss |
| Misread or missing lines | AI re-reads the document and proposes fixes | Found by hand |
| When it runs | As soon as a statement is uploaded | When someone sits down to do it |
| After sign-off | Closed periods are locked; changes are flagged as reopened | Depends on file discipline |
Look for software that proves each month against the statement’s own printed balances, flags missing statements, and locks a period once it’s signed off. ZeraBooks does all three automatically as statements are uploaded, and uses AI to re-read a statement when a month doesn’t tie.
AI can do the slow part: reading the statement, spotting a missed, duplicated or misread line and proposing the fix. In ZeraBooks the arithmetic is done by the ledger, not the AI, and fixes are only proposed when they make the statement tie. You apply them and sign off the month.
Every month, when each statement arrives. In ZeraBooks reconciliation happens automatically on upload, so the only work is reviewing months that don’t tie and signing off the ones that do.
No. ZeraBooks reconciles from the statements you upload as PDF or CSV. That is what makes the proof possible: each statement carries the bank’s own printed opening and closing balances.
Yes. Credit cards reconcile month by month like bank accounts, with payments, charges and net compared between the statement and the ledger.
The month shows a coverage gap, and the next statement shows a chain break because its opening balance doesn’t meet the last closing balance. Upload the missing statement and both clear.
