In this case, you'll want to create the invoice with the correct items, quantities and amounts, approve it, then go to the reconcile screen. When you match the invoice with the corresponding payment, you'll notice that Billy will ask you why the two amounts are different. You'll then code that small amount to the bank fee expense category.
Bank Fee Account
If using Billy's default Chart of Accounts the system is already set up to change the bank fees to account 815 - Bank Fees
To use a different account in your Chart of Accounts you'll need to make a small adjustment to the set up.
- go to Settings > App Settings
- look for Bank synchronization settings section
- update Bank fee account
