DC’s Certified Business Enterprises (CBEs) can legally charge 12% over retail for supply contracts but often charge significantly more if the contract administrator doesn’t pay attention.

I’m not sure about service or construction contracts, but I am aware of at least one construction contract that was DOUBLED because the private firm had to work under a CBE. And many CBEs are District businesses in name only. It’s a good idea but horribly executed. in its current state.
