APMP is the global professional association for bid, proposal and capture practitioners, and in the UK the APMP UK chapter provides certification, best practice guidance and networking for those working on contracts for contracting authorities.

The technology suppliers use to automate and streamline the process of creating, tracking, and submitting bids for public or private contracts.

A formal document a contracting authority or private business uses to ask suppliers how they would deliver a solution, including price, method, and timing, when the requirement isn’t fully defined.
