DPS stands for Dynamic Purchasing System. A DPS is a procurement procedure that can be used by a contracting authority (buyer) to purchase commonly used goods, works and services. For example, food, building works and cleaning services. A DPS is usually set up by a central purchasing body (TUCO) and made available for use by the public sector (our membership). It’s designed to provide buyers (our membership) with access to call-off from a pool of pre-qualified suppliers. Once live, a DPS is effectively a list of pre-qualified suppliers for buyers (our members) to draw from.
