The Hexit website is live: custom development, AI and ERP integration

Our website is live. You'll find the detail of our expertise, the projects we have delivered, and a direct way to reach us and talk them through.

Hexit is a French software development company based in Mérignies in the Hauts-de-France region, about twenty minutes from Lille. We work with small and mid-sized businesses and public bodies across the Lille metropolitan area and the whole of France, from scoping the need through to production, and well beyond.

Our craft is building bespoke software. When an off-the-shelf product imposes its constraints on your organisation rather than the other way round, we design the application that matches how you actually work: web, mobile or line-of-business, built around your users and your real processes.

We connect those applications to the management system you already run. Interfacing with Sage 100, Sage X3 or Batigest: product reference data, negotiated pricing and stock levels stay governed by your ERP, and anything entered on the web side flows back into it automatically. That is what removes duplicate entry and stops two systems drifting apart.

Artificial intelligence integration extends the same logic. AI agents, augmented search across your own documents, automation of repetitive tasks and decision support: the aim is not to add AI for show, but to save time where your teams actually lose it.

We also work on business workflow optimisation — automating a process, connecting tools that ignore each other — and on rewriting low-code or no-code applications that have hit their limits, turning them into durable software with no vendor lock-in. Our consulting and project management support rounds out the offering.

The Projects section shows what that looks like in practice: a B2B e-commerce platform interfaced with Sage X3, a field CRM that works with no network and syncs with Sage 100, an incident and asset management tool, and a field service management application. Each page sets out the original need, the solution and the technical choices.

Got a project in mind? We offer a free thirty-minute audit to pin down your need, identify the levers and point you towards the most suitable approach — including when the best answer is not to build anything at all.

This section will carry our future posts: project deliveries and field notes on ERP integration, offline-first applications and AI applied to business processes.
