The process of matching bank account ledger entries in Business Central against the bank statement, done on the Bank Acc. Reconciliation page.
Bank reconciliation is the process of matching the bank account ledger entries in Business Central against the transactions on your bank statement, so the bank account in BC provably reflects reality. In BC this happens on the Bank Acc. Reconciliation page, one reconciliation per bank account and statement.
You import the statement using a bank statement import format (for example CAMT.053 or a CSV layout defined for your bank), or enter the lines manually. The Match Automatically action pairs statement lines with open bank account ledger entries by amount, date, and text; the rest you match manually. Statement lines with no counterpart in BC, such as bank charges or interest, can be transferred to a general journal, posted, and then matched.
The reconciliation can only be posted when the statement ending balance matches and the difference shows zero. Posting closes the matched bank account ledger entries and stores a Bank Account Statement; recent versions also let you undo a posted reconciliation if a mistake slips through. BC also offers Reconcile with Copilot, which suggests matches and can propose G/L accounts for unmatched lines; the suggestions still require your review before posting.
Do not confuse this page with the Payment Reconciliation Journal: that journal also imports bank statements, but it applies and posts customer and vendor payments, and can optionally reconcile the bank account in the same run.
