I am often asked to translate the French expression: "appel d'offre". In the beginning I didn't have a clue, but after a couple of times I decided to check the English equivalent.
Appel d'offre = Call for tenders
= Call for bids
= Invitation to tender (ITT)
= Request for proposal (RFP) private sector
= Request for tender (RFT) public sector
Répondre à un appel d'offre: = to submit a bid
= to submit a tender
