Custom ERP for companies a generic system was never built to fit

A custom ERP built around your actual production, stock and costing logic, with full source code ownership and no per-seat licensing.

The problem

Your ERP wasn't built for you — it was built for a category of company you resemble on paper. It handles the generic 80% fine and fights you on the 20% that makes your business what it is: a costing method specific to your industry, a stock model that mixes raw materials and finished goods in a way the software's data model doesn't anticipate, an approval chain shaped by your ownership structure rather than a textbook org chart. You end up customizing configuration screens as far as the vendor allows, then bolting spreadsheets onto the gaps, then paying a consultant every time a report needs a field the standard install doesn't expose. License costs climb every year regardless of whether you're using the modules you're paying for, and a platform migration — when you finally consider one — looks so expensive that companies stay on ERPs they've outgrown for years past the point they should have moved, simply because the alternative looks worse than the status quo.

What we build

We build the ERP around your actual operations instead of asking your operations to conform to a vendor's template. That starts with mapping your real production, stock and costing logic — not a generic workshop, but concrete decisions about which module ships first and what the data model needs to represent correctly from day one. The system is built on Next.js with a PostgreSQL database, covering the modules you actually need — inventory, purchasing, production, costing, reporting — rather than a fixed bundle you pay for whether you use it or not. We migrate your existing data in as part of the build, so go-live isn't a blank system. Delivery happens in phases, each one tested against real transactions with your team before the next begins, so you're never staking the whole operation on a single high-risk cutover weekend. At the end, you own the full source code, the database, and the infrastructure outright — no annual license, no per-user fee that grows every time you hire, and no dependency on us to keep the system running if you ever want to change providers.

What you get

Stack

Timeline

Mapping and module prioritization: 2 to 3 weeks. First module live: 6 to 8 weeks. Subsequent modules on a 4 to 6 week cadence based on priority, with a parallel-run period before retiring the old system.

Indicative cost

From roughly €12,000 for a focused single-module ERP replacement up to €25,000+ for a full multi-module system with production, costing and reporting. Each module is quoted after mapping, so cost is tied to what you actually need.

Frequently asked questions

Why replace an ERP we already paid to implement?

If the current system fits your business well, you shouldn't. This is for companies where the fit has become the problem — where every year brings more workaround spreadsheets and more consultant hours just to keep the standard install usable. At that point the sunk cost of the old implementation is smaller than the ongoing cost of working around it.

Is this riskier than staying on an established ERP vendor?

The risk is managed through phased delivery and a parallel-run period — the old system keeps running until the new one is proven on real transactions, so there is no single point where everything has to work perfectly on day one.

What happens to years of historical data in the old system?

We migrate what your operations actually need going forward — current stock, open orders, active accounts, and as much history as is useful for reporting — as part of the build, validated against the source system before cutover.

Does this replace our accounting software too?

Not necessarily — in most builds we integrate with your existing accounting system rather than replacing it, since accounting compliance requirements are usually well served by established software. We scope this during mapping based on what you actually need.

What is the real cost difference versus a licensed ERP over time?

A licensed ERP charges per seat indefinitely, so the cost compounds as you grow. A custom build has a higher upfront cost and no recurring license fee, so the total cost crosses over in your favor once you're past a certain headcount and timeframe — we can work through the comparison with your actual numbers.
