The bank reconciliation first pass
Bank feeds and suggested matches do the bulk of the work. What is left is the exception list, and in small batches it stays short enough to close in one sitting.
- Unrecognised bank charge Investigate same week
- Duplicated payment Reverse and re-file
- Supplier invoice entered twice Void the duplicate
- Unmatched transfer between own accounts Match both legs
- Missing receipt on a card transaction Chase from staff
- Bank feed gap from a new account Reconnect feed
Reconcile within the week and these are the six exceptions you actually see. Let the month close before you start, and the same list becomes a research project.
