What is a dynamic purchasing system or dynamic market?
2 min read · Prepared by TenderChecker
Short answer
A dynamic purchasing system (DPS) is a list of approved suppliers that buyers can invite to compete for specific contracts, and new suppliers can apply to join at any time. Under the Procurement Act 2023, the equivalent arrangement is called a 'dynamic market'.
Key points
- ✓Open to new suppliers throughout its life, unlike most frameworks
- ✓Joining does not guarantee work
- ✓Each contract is then competed among members
How it differs from a framework
Frameworks are usually closed once awarded, so if you miss the window you wait years for the next one. Dynamic arrangements let you apply when you are ready.
How to win work through one
Getting on is usually a suitability check. Winning work means responding well to each mini-competition, often at short notice, so keep strong standard content ready.
