The complete procurement lifecycle: from demand to contract closing
Eleven steps take a purchase from a vague need to a closed contract. Here is what happens at each one, who owns it, and what to check.
Procurement is often described as "buying things", but a well-run purchase is a chain of connected steps. Skipping one usually causes trouble in the next: a missing approval becomes an audit finding, an unrecorded delivery becomes a payment dispute. Here is the whole path, step by step.
1. Demand
Every purchase starts as a need: a team needs new equipment, a project needs a contractor, a building needs maintenance. Capturing demand early, in a simple register, lets you see patterns, combine similar needs and plan the budget.
Check: is the need real, and is it already covered by an existing contract?
2. Requisition
A requisition turns the need into a formal request: what is needed, the estimated value, when it is needed and why. It goes to an approver with authority over the budget.
Check: is there a business justification, and is the budget available?
3. Sourcing
Once approved, you go to market. You choose the instrument (a tender, an RFQ or an RFP), publish the notice with its eligibility rules and scoring criteria, answer vendors' questions openly and wait for the closing date. See our guide to choosing between a tender, RFQ and RFP.
Check: are the criteria published before offers arrive, and did every bidder get the same information?
4. Award
Offers are evaluated against the published criteria. The best-value offer wins, and the decision is recorded. In many systems a contract award notice is then published, showing the winner and value.
Check: can you explain the decision from the scores alone?
5. Purchase order
The award is converted into a purchase order (PO). It states the vendor, price, delivery date and terms. The buyer's signature on the PO is the offer to buy.
Check: do the price and terms match the awarded offer exactly?
6. Vendor management
Procurement does not end at the award. You keep a view of each vendor: how reliable they are, whether they deliver on time and how often deliveries fail inspection. Over time you can mark vendors as preferred, put them on a watch list or block them.
Check: do you act on what the scorecard tells you?
7. Contract execution
The vendor accepts the purchase order and signs it electronically. From that moment the contract is binding, and work begins. The record should show who signed and when.
Check: is there a signed record, with the terms, before work starts?
8. Delivery
The vendor delivers the goods, services or works and records the delivery against the order. Notes on what was delivered, and when, make later disputes much easier to settle.
Check: was the delivery on time and complete?
9. Inspection
The buyer checks the delivery against the order. If it passes, the process moves on. If it fails, the buyer records why, and the vendor must put it right and deliver again.
Check: is every rejection explained clearly enough for the vendor to fix it?
10. Payment
Only an accepted delivery should be paid. The vendor sends an invoice for the accepted amount, and the buyer pays and records the payment against it. Never pay more than the order value, and never pay before acceptance.
Check: does the invoice match the order, and does the payment match the invoice?
11. Contract closing
When everything is delivered and paid, the contract is closed. The buyer records a performance rating, which feeds into future sourcing decisions, and the file is archived.
Check: is every obligation complete, and has the vendor's performance been recorded?
Why the whole chain matters
| If you skip... | You risk... |
|---|---|
| Requisition approval | Unauthorised spending |
| Published criteria | Challenges from losing bidders |
| A signed purchase order | Disputes about price and terms |
| Delivery records | Paying for things you did not receive |
| Inspection | Accepting defective work |
| Performance ratings | Re-hiring poor vendors |
The bottom line
Procurement works best as one connected process, with every step recorded and linked to the one before. That is what a good e-procurement platform provides: one place where the need, the notice, the award, the order, the delivery and the payment all tell the same story.
