Custom development

Custom software development for businesses that genuinely need it.

When off-the-shelf doesn't fit, patches don't fix it either. We design, build and maintain software that adapts to your real-world operations — with the code open from day one and a first working version in weeks, not months.

When it genuinely pays off

Custom software isn't for everyone. And that's fine.

If your operations fit any off-the-shelf template on the market and there's nothing about the way you work that sets you apart, a standard package probably works for you. That makes sense, and we won't try to convince you otherwise.

But if you've spent a while fighting software that never quite fits — modules nobody uses, parallel spreadsheets, processes that still depend on email and on whoever knows the trick — then the patches are already costing more than building it properly once. That's where we come in.

Unique processes

The way you work is part of why you work well, and you don't want to give it up just to fit a piece of software.

Systems that don't talk to each other

You use several programs and pass information between them by hand. Or worse: you don't pass it at all.

Excel as a permanent plan B

Whatever the software doesn't cover well ends up being solved outside the software, with everything that implies.

Growth held back by the tool

To scale, you'd need to hire someone just to make up for what the system doesn't do.

What we build

From internal apps to full ERPs. All adapted to how you work.

01

Custom ERP →

Management system adapted to your real-world operations. Purchasing, sales, warehouse, production, CRM and analytics in one single system.

02

WMS and logistics

Real-time warehouse management, batch and location traceability, route optimisation and digital signing of delivery notes.

03

Operational apps

Mobile and desktop applications for field teams, points of sale, warehouse operators or service technicians.

04

Integrations and APIs

Connectors between ERP, CRM, online stores, payment gateways, accounting software and any other system you already use.

05

Automation

Repetitive manual processes turned into automatic workflows. Fewer errors, less wasted time, more traceability.

06

Dashboards and BI

Dashboards with the metrics the business checks every day. Data consolidated from several sources, without opening five applications.

Not on the list? Ask us anyway. Half of real projects don't fit a standard box — that's why they come to us.

How we work

A process with no mysterious phases, no surprise deliveries.

01

Diagnosis

We spend time with the people who run the processes. We map out where it actually hurts and why.

02

Scope and prototype

We agree what gets built in the first phase. Within weeks there's a working version you can already try.

03

Iteration

Short sprints with continuous demos. You use what already works while new modules get added.

04

Handover and support

Technical documentation, handover to your in-house team and ongoing support if you need it. The code is yours from the very first commit.

Non-negotiable principles

How we work when nobody's watching.

Custom software works when there's trust. These four principles are what makes that trust survive the project.

The code is yours

Your repository, your access, your licence. No lock-ins or closed modules that only we understand.

Delivery in phases

The first version lives in production within weeks, not months. We iterate on real feedback, not assumptions.

Proven stack

Standard, mature technologies with a community behind them. No experiments that only we can maintain.

Documentation included

Commented code, technical and user documentation, and handover to your team whenever you want to take it in-house.

Ways to hire us

Closed project or continuous evolution.

Closed project

Defined scope, delivery in phases

Ideal when you know exactly what you need and want a concrete delivery. We agree scope and phases, work in sprints with demos, and there's a full handover at the end.

Includes technical and user documentation. Ongoing support is contracted separately if you need it.

Monthly retainer

Continuous development team

For businesses whose system never stops evolving and who'd rather have dedicated development capacity every month. A mix of new features, fixes, enhancements and support.

No annual commitment. If a month doesn't need anything, it rolls over.

Frequently asked questions

What people ask us before getting started.

When does custom software pay off compared to a standard one?

When you've spent a while fighting a standard package: modules nobody uses, parallel spreadsheets to cover what it doesn't do, fragile integrations that break with every update. If those patches are already costing more than building it properly once, custom software pays off — and keeps paying off as the company grows, because the system grows with you.

What kind of projects do you build?

Custom ERPs, warehouse management systems, operational apps for field teams, integrations between systems that don't talk to each other, automation of manual processes, dashboards for management, connectors to legacy ERPs or online stores. If it's about digitising a company's real-world operations, we've either done it or can do it.

What's the process once we contact you?

First a conversation to understand what's hurting. If there's a fit, we spend a few days with the people who actually run the processes to build a real diagnosis. From there we agree scope and a first phase — usually within a few weeks there's something functional in production. The rest gets built in short iterations, with the company using the system from day one.

Can we see the project as it progresses?

Yes, and we consider it non-negotiable. You have access to the repository from the start, we run demos every sprint, and the test environment is available 24/7. No projects that kick off and stay invisible until final delivery.

What happens with maintenance once it's delivered?

You can contract monthly support for enhancements, fixes and new features. If you'd rather run it with an in-house team, we leave technical documentation and hand it over properly. The code is yours from the very first commit — no vendor lock-in.

Is it possible to migrate from standard software to a custom one?

Yes, it's one of the most common scenarios. We do it in phases: first we cover the processes that work worst today, the old system gets switched off module by module, and in the end there's a single system that actually fits. Data migration is part of the project, not a separate phase left for the end.

Tell us what doesn't fit. We'll tell you if custom software makes sense.

First conversation, no strings attached. If we don't see a fit, we'll say so and that's it — not everyone needs custom software, and we won't try to convince you otherwise.
