What Is a Dynamic Purchasing System and When Is It Used

Antoine Simon2026-03-269 min readv1.0.0

The Dynamic Purchasing System — commonly abbreviated as DPS — is one of the most supplier-friendly procurement mechanisms in European public procurement. It combines the efficiency of pre-qualified supplier panels with a critical feature that traditional framework agreements lack: the door never closes. New suppliers can join at any time.

Despite its advantages, the DPS remains less well-known than frameworks among suppliers new to public procurement. The European Commission's procurement guidance notes DPS as an important tool for promoting competition. This guide explains what a DPS is, how it works in practice, when contracting authorities use it, and why it matters for your B2G strategy.

What is a Dynamic Purchasing System?

A Dynamic Purchasing System (DPS) is a completely electronic procurement process for commonly used purchases. It operates as an open-access pre-qualification system: any supplier that meets the published criteria can join at any point during its lifetime, and individual contracts are awarded through electronic mini-competitions among qualified participants.

The legal basis is Article 34 of Directive 2014/24/EU, which defines the DPS as:

A completely electronic process which is open throughout its duration to any economic operator that satisfies the selection criteria. It may be divided into categories of products, services or works.

Three defining characteristics set the DPS apart:

  1. Always open — New suppliers can apply to join at any time
  2. Fully electronic — The entire process, from application to award, must be conducted electronically
  3. No fixed duration limit — Unlike frameworks (maximum four years), a DPS can run indefinitely

DPS vs framework agreement: the key differences

Since both DPS and framework agreements serve similar purposes — creating pre-qualified supplier panels for recurring purchases — understanding the differences is essential.

Feature Framework Agreement DPS
Supplier panel Closed after award Open throughout duration
Maximum duration 4 years (with exceptions) No limit
New entrants Not permitted after establishment Welcomed at any time
Process Can be partly paper-based Must be fully electronic
Procedure for award Open, restricted, or negotiated Must follow restricted procedure rules
Call-off mechanism Direct award or mini-competition Always mini-competition
Categories Lots Categories (functionally similar)

The "always open" characteristic is the most strategically significant difference. If you miss the deadline for a framework competition, you are locked out for up to four years. If you miss the initial DPS setup, you can apply next week — or next year — and join the same DPS.

How a DPS works in practice

Phase 1: Establishment

The contracting authority publishes a contract notice on TED (for above-threshold DPS) announcing the establishment of the Dynamic Purchasing System. The notice includes:

  • Scope — What goods, services, or works the DPS covers
  • Categories — If the DPS is divided into categories (similar to lots)
  • Selection criteria — The qualification requirements suppliers must meet
  • Duration — How long the DPS will operate
  • How to apply — The electronic platform and application process

The notice remains published on TED for the entire duration of the DPS. This is unusual — most procurement notices are published once and then archived. A DPS contract notice is a standing invitation.

Phase 2: Initial qualification

Suppliers submit their applications (requests to participate) through the contracting authority's electronic procurement system. The application follows restricted procedure rules and includes:

  • Evidence of meeting selection criteria (financial standing, technical capability, etc.)
  • Self-declarations or completed European Single Procurement Document (ESPD)
  • Any required certifications or registrations

The contracting authority must evaluate applications within 10 working days of receipt during the initial setup phase. After the DPS is established, the standard evaluation period is 10 working days for each new application.

If you meet the criteria, you are admitted to the DPS. If your application is rejected, you receive the reasons and may re-apply after addressing the deficiencies.

Phase 3: Ongoing operation — call-offs

When the contracting authority has a specific requirement, it runs a mini-competition among all suppliers admitted to the relevant DPS category:

  1. Invitation — All qualified suppliers in the relevant category receive the call-off specification
  2. Response — Suppliers submit proposals and pricing electronically
  3. Evaluation — The contracting authority evaluates responses against stated award criteria
  4. Award — The winning supplier is notified; standstill period applies for above-threshold awards

The call-off deadlines are typically shorter than full procurement timelines, but all qualified suppliers get an equal opportunity to compete.

Phase 4: Ongoing admission

Throughout the DPS's operation, new suppliers can apply to join. The contracting authority must:

  • Keep the original contract notice accessible
  • Evaluate new applications within 10 working days
  • Admit any supplier that meets the published selection criteria
  • Include newly admitted suppliers in all subsequent mini-competitions

This ongoing admission process is what makes the DPS "dynamic."

Directive 2014/24/EU, Article 34

The primary legal basis for DPS in classic public procurement. Key provisions:

  • DPS must be run as a completely electronic process
  • Open throughout its validity to any economic operator satisfying the selection criteria
  • May be divided into categories, each defined objectively based on the characteristics of the contracts
  • Establishment must follow the rules for restricted procedure
  • All communications within the DPS must be electronic

Directive 2014/25/EU (Utilities)

Article 52 provides equivalent rules for utilities sector DPS, with similar provisions adapted for the utilities context.

National implementation

Member states implement DPS rules through national procurement legislation:

  • Germany — GWB (Section 120ff) and VgV (Section 22) implement DPS provisions. The tool has seen growing adoption by federal and state procurement offices.
  • France — Code de la Commande Publique (Articles R2162-37 to R2162-45) transposes the DPS rules. French contracting authorities increasingly use systemes d'acquisition dynamiques for standardized purchases.
  • UK — Post-Brexit, the Procurement Act 2023 retained and expanded the DPS concept under the term "Dynamic Market" with additional flexibility.

When contracting authorities use a DPS

Commonly available goods and services

The DPS is designed for purchases that are "commonly available on the market." This includes:

  • Office supplies and consumables — Paper, toner, stationery
  • IT hardware — Laptops, monitors, network equipment, servers
  • Temporary staffing — Agency staff across various categories
  • Training services — Professional development, language courses
  • Vehicle fleet — Cars, vans, specialist vehicles
  • Construction trades — Electrical, plumbing, painting, specialist works
  • Facilities supplies — Cleaning products, catering supplies

Markets with many potential suppliers

The "always open" feature is most valuable when there are many potential suppliers, including small and medium enterprises that might not be tracking procurement opportunities at the precise moment a framework is competed. A DPS for IT consulting, for example, recognizes that new companies form, existing companies expand their capabilities, and the market evolves over time.

Long-term recurring needs

Because there is no statutory duration limit, DPS suits long-term programs of work where the buying authority wants to maintain access to the full market over many years without periodically re-procuring a framework.

Innovation-driven markets

In fast-moving sectors where new entrants and new solutions emerge frequently, a closed framework panel becomes outdated quickly. A DPS allows the supplier base to evolve with the market.

Practical implications for suppliers

Lower barrier to entry

The DPS is the most accessible above-threshold procurement mechanism for suppliers. You do not need to compete against established incumbents in a single high-stakes evaluation. You need to meet published selection criteria — which are typically pass/fail qualification requirements, not competitive assessments. If you are qualified, you are in.

Ongoing opportunity

Unlike framework agreements where missing the competition window means waiting four years, a DPS lets you join when you are ready. Launched your company last year? Expanded into a new service area? Obtained a new certification? You can apply to join an existing DPS immediately.

Competition at call-off level

While joining a DPS is relatively straightforward, winning call-offs requires competing against every other qualified supplier on the panel. DPS panels tend to be larger than framework panels (because of the open-access policy), which can mean more competition for each call-off.

Electronic capability is mandatory

A DPS is entirely electronic. You must be able to receive invitations, submit proposals, and manage the commercial process through the contracting authority's e-procurement platform. This is not optional — it is a legal requirement of the DPS process.

Stay active and responsive

Being admitted to a DPS does not mean you will be notified through personal channels. You need to actively monitor the e-procurement platform for call-off opportunities. Setting up notifications and checking regularly is essential — missed call-offs are missed revenue.

Common misconceptions

"A DPS is just a framework by another name." The "always open" feature fundamentally changes the dynamics. Framework panels are static; DPS panels are fluid. This affects competition intensity, market entry strategy, and long-term planning for both buyers and suppliers.

"Anyone can join a DPS regardless of capability." The DPS has published selection criteria that must be met. The difference from a framework is that these criteria are applied on a pass/fail basis for admission, rather than competitively. You still need to demonstrate financial standing, relevant experience, and technical capability.

"DPS call-offs are easier to win than framework call-offs." If anything, the opposite may be true. DPS panels are typically larger than framework panels, meaning more competitors for each call-off. The qualification barrier is lower, but the competition at call-off level can be fiercer.

"The DPS is rare in practice." While historically less common than framework agreements, DPS adoption has accelerated significantly since the 2014 directives simplified the process. Countries like the UK (with its "Dynamic Markets" under the Procurement Act 2023), the Netherlands, and Nordic countries have embraced DPS extensively.

"Small companies cannot compete on a DPS." The DPS is arguably the most SME-friendly above-threshold mechanism. The ongoing admission process, electronic management, and absence of a winner-takes-all framework competition all favor smaller suppliers who can compete effectively on specific call-offs.

How Duke helps

Dynamic Purchasing Systems create a specific monitoring challenge: the contract notice stays live for years, and call-offs may be published only to admitted suppliers on the e-procurement platform. Knowing which DPS opportunities exist across European markets — and which ones are relevant to your business — requires systematic tracking.

Duke supports DPS strategy by:

  • Identifying active DPS notices — Filtering TED and national platform data to surface DPS opportunities in your sectors and geographies
  • Tracking DPS categories — Understanding which categories are available within each DPS and matching them to your capabilities
  • Monitoring DPS awards — Analyzing call-off award data to understand competitive dynamics, pricing levels, and buyer patterns
  • Alerting on new DPS establishments — Notifying you when new DPS systems are set up by contracting authorities in your target markets

For suppliers building a B2G pipeline, DPS systems represent ongoing, accessible market entry points. Having visibility into the full landscape of active DPS opportunities across Germany, France, and other European markets is a significant competitive advantage.

Conclusion

The Dynamic Purchasing System is a procurement mechanism designed for the realities of modern markets: evolving supplier bases, recurring needs, and the imperative to keep competition open. Its "always open" admission policy makes it the most accessible form of above-threshold EU procurement for suppliers of all sizes.

For B2G companies, the strategic implications are clear. Every active DPS in your sector and geography is a potential market entry point that you can pursue on your own timeline. The qualification barrier is manageable, the process is electronic and efficient, and the ongoing mini-competition model rewards suppliers who deliver value consistently.

The challenge is visibility. Knowing which DPS systems exist, which categories are relevant, and when call-offs are happening requires structured procurement intelligence. Companies that combine DPS awareness with active call-off participation build the kind of consistent public sector revenue pipeline that spot-bidding on individual tenders cannot match.
