Can I ask some opinions on what the correct terminology This is important for my software haha. I dont want to confuse people. 1. Tender vs Bid. Which word do you use to describe the set of documents your client sends you? 2. Direct vs Indirect cost. What do you call a cost you incure, but don't want to show in the cleient pricing schedule 3. Letter of offer. Is that the word you use to dsecribe the letter you submit to your client detailing your inclusions and exclusions?
