What is bank reconciliation and why does it matter

Bank reconciliation is the check that your books agree with your bank. You take what the bank says happened, the statement, and confirm every line is recorded in your books once and correctly, with nothing missing and nothing invented.

Why it matters. Your reports are only as good as the data under them. If a transaction was entered twice, or a bank fee never made it into the books, or a deposit was recorded for the wrong amount, your profit and your cash balance are both wrong, and you will not know it until the numbers are questioned. Reconciling is what catches those before they reach a report or a tax filing. It is also how you spot a charge you did not make.

What it looks like in practice. You pick an account and a period, enter the closing balance from the statement, and tick off each transaction against the book entry until the two match to the cent. A leftover difference is the flag that something needs attention, not a rounding quirk to wave off.

Where TALISK_HQ fits. TALISK_HQ reconciles under Ledger › Banking › Reconciliation: connect the account or import a statement, then work down the list. If a statement does not tie out, TALISK_HQ points at the specific rows rather than the whole month: see why doesn't my statement tie out.
