By the AIA retainage invoice, are you referring to the AIA worksheet report that you could print in Plus Job Costing? Indeed this report was not included in the initial release of Adagio JobCost.

Or are you referring to an invoice specification in Adagio Invoices, which you wish to customize in order to print certain (job cost related) information to conform to AIA requirements? We haven't created any Adagio Invoice sample specifications to meet these requirements - could you indicate what information is necessary?
