we are a company that does project based work with a request at the begining of each project for a deposit payment.

At the moment we are creating invoices for the deposit and an invoice for the completion of the project, however they are completely seperate invoices.

Has anyone got a suggestion on how we can do this as a single invoice in Zoho Books, for instance.

Project ABC 

Total Cost $50,000

Deposit Payment $25,0000

Then when we invoice for the final amount it is clear that it is all one invoice

thanks in advance
