The contact is set up with billing rules, and the project type is fixed price The project is linked to a customer A, but we need to invoice one part of this customer and the other to another customer B.
I've added the customer B as an additional funding source to the contract, but by default, when I generate the invoice, it uses the initial customer.
Is it possible to set a funding source by milestone: for one customer and another for another?
Or while generating the invoice proposal choose the funding source?
How to manage this scenario?
