Procurement cycle
The procurement cycle is the sequence of planning a need, engaging the market, choosing a route, inviting and evaluating offers, awarding and mobilising a contract, managing delivery and closing or re-procuring it. The detail varies by buyer, jurisdiction and contract.

A public purchase does not end when a supplier submits a tender: the procurement cycle covers the sequence from defining the need through contract delivery and exit. It is a useful planning model rather than one universally fixed legal checklist. The stages and notices depend on the buyer, contract, value, jurisdiction and applicable regime.
Common stages
A buyer may define the business need, analyse the market, engage suppliers, choose a route and prepare the specification and contract. It then publishes or issues the opportunity, receives participation information or tenders, evaluates against the stated criteria, communicates the outcome, completes any standstill and awards the contract. Mobilisation, performance management, payment, change control, exit and transition follow.
Map supplier activity to the cycle
Suppliers should map their own work to the cycle. Capture and bid decisions happen before submission; tender response and clarification happen during procurement; mobilisation planning tests whether promises can be delivered; contract management turns those promises into performance. Do not assume that an early pipeline or market notice means a contract will be issued.
The Procurement Act 2023 changed the notice and procedure framework for new in-scope procurements from 24 February 2025, while transitional procurements continue under their applicable previous rules. Scottish procurement has separate legislation and guidance.
For example, a supplier may spot a planned procurement, attend market engagement, bid at tender stage, prepare mobilisation after award and support a service review before renewal. Each stage has different evidence and decision owners.
