Incremental funding of GSA FSS orders in Schedules, GWACS, MACs, IDIQs Posted Wednesday at 03:12 PM · Report reply Let’s start here. Have you read FAR part 32? To add context take a look at the DFARS supplement part 232that drills down further to incrementally funded contracts. Does your agency have a FAR supplement that does the same? Finally read the terms and conditions of the specific GSA FSS contract that the order will be placed against and if not addressed do you believe you can add further terms and conditions to the order to allow for the incremental funding. If this effort does not answer your questions, if not why not?
