Do your books tie to your bank?

Bank reconciliation is the single biggest time sink in a bookkeeping firm. Paste your bank export and your ledger — this independently recomputes the tie-out and shows every line that's in one but not the other, whether the totals agree, and whether the balance foots. It finds the disagreements; it does not replace your accounting software.

What it checks, and what it honestly doesn't

Reconciliation is checking that two records agree: the bank's record of what actually cleared, and the ledger of what was recorded. Nobody re-derives it independently — they eyeball it, and a missing entry or a fat-fingered amount slips through and compounds.

What it checks

  • Totals tie. The sum of the bank equals the sum of the ledger.
  • Every line matches. Each bank line has a ledger line (amount within a cent, date within a few days; a matching reference wins outright) and vice versa. Unmatched either way is flagged — cleared but unrecorded, or recorded but never cleared.
  • The balance foots. Opening + bank activity = closing, when you supply both.
  • Duplicates. The same line recorded twice on either side.

The verification slice, not the automation

This does not categorize transactions or replace QuickBooks/Xero. It's the independent recompute on top — it tells you where the two records disagree. That's the part that contains no opinion and produces the same list for anyone who re-runs it.

What it honestly does not do

A clean reconciliation shows the two records you supplied agree — not that either is correct. If both are wrong the same way, they reconcile perfectly. Same engine as the ARR reconciler.
