Abstract: Systems and processes are disclosed for validating and processing invoices for labor, service contracts, equipment and/or other resources against data representing actual expenditures and expectations set forth by project management systems and software. An accrual and validation database identifies duplicate invoices, erroneous contractor rates and/or erroneous contractor hours by identifying and reporting variances, accrued costs and other information. A project management database associates approved work with sponsoring budget centers so that general ledger transactions may be generated to allocate approved invoice charges.
