What is Procurement Policy?

Updated: 22 March 2026

A procurement policy is a formal set of rules and guidelines that determines how an organisation purchases goods and services. It defines who is authorised to buy, from which suppliers, under what conditions and with what approval levels. For SMEs, a procurement policy prevents uncontrolled spending, ensures consistent supplier selection and creates the foundation for effective contract management.

How does procurement policy work?

A procurement policy sets the boundaries within which employees may make purchasing decisions. It answers the practical questions that arise every time someone in the organisation needs to buy something: who approves this purchase? Do we need multiple quotes? Is there a preferred supplier? What is the maximum value I can sign off on my own?

Without a written policy, purchasing decisions are made on an ad-hoc basis. One employee orders from a supplier they found online, another uses a contact they know personally, and a third simply picks whoever is cheapest today. The result is inconsistent pricing, fragmented supplier relationships and contracts that nobody monitors after signing.

A good procurement policy does not need to be long or complex. For most SMEs, it covers four elements: spending thresholds with corresponding approval levels, a list of preferred suppliers by category, rules for obtaining competitive quotes above a certain value, and a requirement to record all purchases above a minimum amount in a central system.

The policy should also clarify who is responsible for supplier selection, contract negotiation and ongoing contract monitoring. Many procurement problems in smaller businesses arise not because people act in bad faith, but because nobody has defined who is responsible for what.

Implementation matters more than documentation. A policy that exists only as a PDF on the intranet achieves nothing. The rules need to be embedded in the actual purchasing workflow, whether that is through software controls, approval chains or regular training.

Why does this matter for SMBs?

Without a procurement policy, every purchase is a standalone decision made without consistent criteria. This leads to maverick buying, where employees bypass preferred suppliers or agreed pricing. According to the Hackett Group, 10 to 20 percent of targeted procurement savings are lost to this kind of uncontrolled spending. Given that external purchasing accounts for an average of 43 percent of total business costs (Bain & Company), the impact on margins is substantial.

A clear policy also protects the organisation legally and financially. It ensures that contracts include the right terms, that spending stays within budget and that suppliers are selected based on objective criteria rather than personal preference or habit.

How to manage this correctly

1Define spending thresholds with clear approval levels, for example under 500 euros requires no approval, 500 to 5000 requires a manager, above 5000 requires the director
2Maintain a preferred supplier list per category and require justification when purchasing outside that list
3Require at least two competitive quotes for any purchase above a defined threshold
4Review the policy annually and update it when the organisation grows or its supplier base changes
5Make the policy accessible and train new employees on it during onboarding rather than burying it in a document library
