Hi

I created a budget inside an analytical account to know the rentability of the construction of a house. My client is paying me in installments, so month by month I`am registering them in the invoice. 

I would like the budget to reflect the current economical state of the proyect, but when I associate the invoice to the analytical account, the whole total is applied inmediatly to the budget.

A solution that I found is to put the analytical account inside the accounting seat that it's generated when I register a Payment. But with this method there is the problem that the gross margin register more money than it should.

Does anyone have a good solution for this?
