Hi Quickbooks Gurus,

We do engineering consulting at an hourly rate.  We normally create an estimate for the project, then accept a 50% down payment up front before the work has started. My client has asked me to invoice them for the down payment, but if I create an invoice and they pay it, it's not going to remain a credit towards their account. How do I create an invoice for a down payment for a client for a project and still keep the credit in the system to be applied towards the hours we work on their project?

Thanks for your advice!
