We are trying to implement Acumatica (Construction) and we would like to have 2 allocation rules 1) for fixed price projects where COGs and Revenue is recognized as a % of completion and 2) an Allocation Rule where costs, including overhead, accumulate in WIP until the project is invoiced.

We are 99% there with the fixed price, but for time and material, the Allocation Rule is crediting the overhead expense for the correct amount, but is showing a negative expense balance on the project.  The GL accounting is correct, but the project accounting is not.  Any help on modifying the allocation rule would be appreciated.
