It's great to here again from you, @Kitkat2.

Allow me to join the conversation and provide additional details on how to determined whether a recorded invoice is billable.

If I may ask, are you perhaps referring to the invoice your vendor gave to you? If yes, when you received an invoice from a vendor it will be recorded as a bill in the system.  You can verify whether an invoice is billed if there's a check mark on the column that says Billable.

On the other hand, to ensure the estimates and invoices you created are tracked accurately, here's the correct workflow:

1. Create an estimate  
2. Create a sales order 
3. Create an invoice 
4. Record a payment 
5. Deposit customer payments

That should do it! If you need further help with the workflow above, I'd recommend contacting our Customer Care Team. An agent will be able to further assist you via secured remote access session.
