Thank you for your reply.
It is a CPFF contract. A certificate was not submitted for the year I am preparing the incurred cost for because it was competitive. The proposal did not take into account the mandatory source of supply and materials were proposed based on quotes from other vendors.
There are no critical parts involved, most of the items that should have been purchased from AbilityOne are office supplies, some office furniture such as chairs and mats, toner cartridges, and cleaning supplies. Yes, these are typically overhead but are direct on this contract.
