My bank balance in Ledgri doesn't match the bank

Look at the size of the difference first. If it equals one transaction, search for that amount with Ctrl K.

Common causes:

1. Transactions waiting for review. Anything still under For review in Transactions isn't in your books yet.
2. Duplicates. A customer payment recorded by hand and categorized again from the bank. Undo the categorized one and match it instead.
3. A wrong starting balance. Check the account's balance on your start date against your statement for that day.
4. Uncleared cheques. Cheques you've written that haven't been cashed are in Ledgri but not yet at the bank. That's normal; they'll clear.
5. Wrong account. A payment recorded to the wrong bank account.

Reconciling each month finds these quickly.
