Buyer No-bid Response / Reason

Buyers can specify the reason of not bidding in their No Bid Responses (NBRs) to BidSwitch. A no-bid response contains the nbr field which indicates why the Buyer did not bid on the request. The currently supported no-bid reasons are listed in the table below.

By returning this information to Suppliers, it allows them to address potential problems in their system. If a No Bid Reason is returned, BidSwitch will send that to the Supplier and should a recurring problem surface steps can be taken to fix it.
