Frequently asked questions

What is the Procurement Act?

The Act on Public Procurement and Concession Contracts (1397/2016), known as the Procurement Act, governs how the state, municipalities and other public buyers acquire goods, services and works. Its basic idea is to give companies an equal opportunity to offer their solutions to the public sector.

What are the most important principles of the Procurement Act?

Equal treatment and non-discrimination (no one may be favoured), transparency (tenders are announced publicly and decisions are reasoned) and proportionality (the requirements must be in proportion to the size of the procurement).

When does the Procurement Act apply?

When the estimated value of the procurement exceeds the national threshold — for goods and services, EUR 60,000, for example. Smaller purchases are small-scale procurements, governed by the buyer's own procurement rules.
