If your business works with cash transactions, you are in some countries required by law to keep a cash book. Billit lets you keep this cash book digitally.
To link an invoice to a particular transaction, click on the transaction after adding it in the cash book. A screen will appear with the transaction details. You can manually link the correct invoice (or invoices) to it. You do this by clicking ‘Link to transaction’ at the desired invoice (or invoices).
If you cannot find the invoice in the list, use the search function.
You can also add additional internal information about the transaction in the details screen.
