About us

Good for buyers.
Good for suppliers.
Built for European procurement.

Procurement works better when access is fair and competition is based on merit. Buyers get a platform they can trust. Suppliers compete on the quality of what they offer, and public and private spending has a more transparent, responsible impact. That's the marketplace we've been operating for more than two decades. And it continues to guide how we function.

WHO WE ARE

Founded in Europe.
Built on conviction.

Unite is a European procurement platform headquartered in Leipzig, operating across 12 countries and serving thousands of public and private organisations. Founded in Munich in 2000 as Mercateo, we recognised an opportunity to make procurement work better for everyone. As we expanded across Europe and broadened our services, we rebranded as Unite in 2022.

WHAT MAKES US DIFFERENT

Built on fairness and transparency.

Our focus is on making procurement simpler, fairer and more transparent. That commitment continues to shape our platform, our partnerships and the way we do business across Europe.

The choices we made to build a procurement platform people can trust. It's what makes Unite different.

Full accountability.

As your single-creditor partner, we take on the financial risk – giving you one accountable partner for every transaction.

Millions of products with data consistency.

Good decisions depend on reliable product data. We classify, structure and maintain data across your procurement journey because the quality of your foundation determines the quality of every decision built on it.

Transparency is at the heart of how Unite works. Our clear service fee is separate from the purchase price, so organisations always understand what they are paying for and why.

Our experts will guide you.

Our specialists work alongside your team from day one. Not just to implement, but to remain embedded in your operations, supporting, adapting and evolving with your procurement setup.

Your interests. Our priority.

We've no supplier commissions and no hidden incentives. We succeed when you achieve better procurement outcomes, not when you spend more. This has always been our commercial model.

OUR RESPONSIBILITIES

We measure our business against independent benchmarks.

Doing business responsibly is part of who we are – not a programme we run, but a conviction we act on. That's why we choose recognitions that can be independently verified.
