Multi-tenant SaaS platform

Negometrix, nowadays Mercell, was a Dutch e-procurement platform that we built from the ground up. Over fifteen years, our team took it from an idea to the dominant e-tendering solution in the Netherlands — serving thousands of organizations and processing billions of euros in contract value.

The platform was later acquired by Mercell, one of Europe's largest procurement groups, and is still operational on the Dutch market.

The challenge

Public procurement is one of the most demanding domains to build software for.

1.

Government buyers expect zero downtime, airtight compliance, and workflows that handle every edge case in the tendering process.

2.

Suppliers needed a portal that feels simple and intuitive — even when the underlying processes are anything but.

3.

The platform required multi-tenant architecture with strict data isolation, advanced contract management, a public API, and the reliability standards that come with government clients.

Our solution

We started building in 2006 and treated the platform as our own product — architecture designed for scale from day one on .NET.

We launched NX3 in 2009, then rebuilt the platform from the ground up and relaunched as NX4 in 2017 with a modern frontend and the lessons of eight years baked into every decision.

The same dedicated team delivered every sprint, every release, and every migration across the full twelve years. No handoffs, no ramp-up periods, no lost context.

Results

Fifteen years of compounding work — and a successful exit.

Thousands of organizations across the Netherlands — municipalities, water boards, healthcare institutions, and private companies.

Billions of euros in public and private contract value processed through the platform.

Acquired by Mercell after fifteen years, validating both the technical foundation and the market position.

Still operational on the Dutch market today, serving the same clients we onboarded years ago.

Working with the Dextrasoft team was a game-changer. Their expertise in building scalable platforms helped us grow to become the leading e-procurement solution in the Netherlands.
