You can combine clients onto one invoice by moving the accounts of one client to another client in BillFin. If I had client Jane Smith with accounts #1 and #2 and a client John Smith with accounts #3 and #4. I would move John’s accounts to Jane’s client, and then change Jane’s client name to Jane and John Smith.
To Move an Account to a Different Client/Invoice:
Go to the Clients page
Find the client with the account(s) you want to move
Click on the client name to display the account(s) underneath
Move your cursor to the account you want to move
A pencil will display next to the account name
Move the mouse to the pencil to display the menu
Click “Move Account"
This will open a popup box where you can select the client to which the account should belong
-After moving the accounts, you can edit the client name. (In the example above I would change "Jane Smith" to "Jane & John Smith." Don't delete any clients even if they no longer have any accounts.)
