Once contract “A” is entered into by a supplier (see description for the term contract “A”), the acceptance of that contract is considered to by an invitation from that supplier for the buyer to enter into what’s referred to as contract “B” (also referred to as the “performance contract”). Contract “B” can be entered into with any of the suppliers that have entered into contract “A”. Contract “B” typically defined working parameters, goods and services to be delivered, and pricing obligations to be upheld by both the buying and supplying parties. On Tradogram, contract “B” can be considered as entered into when the terms provided in a supplier response are accepted and used to create a contract or a purchase order document on the system (multiple contract “B” arrangements can be created through the system, depending on the situation).
