Custom Software

Custom software & integrations for SMEs.

When no tool fits, we build it. Software and integrations that give you hours back every week – docked onto the systems you already have.

Integration, not replacement

Your systems stay. We dock on.

Custom software, the way we do it, doesn't mean starting over. It means building the missing piece. Integrations instead of system swaps – so your ERP, CRM, accounting, inventory management, and email inbox finally talk to each other.

Ehrliche Antwort

Often a standard tool is enough.
When isn't it?

Custom software development is not an end in itself. If Make.com or n8n solves your problem, we'll tell you – it's cheaper, and you're live sooner. Custom software pays off when:

Your process doesn't fit any tool.

You've tried it in three tools and ended up bending your workflow every time – instead of the tool.

Your systems don't talk to each other.

The integration that would connect your ERP and your shop simply doesn't exist. So we build it.

License costs are getting out of hand.

30 users × €40 × 12 months – past a certain size, owning your solution is cheaper than renting one.

The process is your business.

What sets you apart from your competitors doesn't belong in a tool anyone can rent.

The building blocks

Five things we build – when they're missing.

Integrations & APIs

ERP ↔ shop, CRM ↔ accounting, legacy system ↔ cloud. Data flows automatically – nobody retypes anything anymore.

Internal Tools & Dashboards

The Excel file three departments are failing at simultaneously becomes a tool with permissions, history, and one version of the truth.

Customer Portals

Orders, status, documents – your customers look it up themselves instead of calling you.

Automation Backends

The machine behind the machine: order processing, data pipelines, billing logic – runs at night, only speaks up on exceptions.

AI Features in Your Existing Software

Your system stays and still gets AI: text recognition, classification, suggested replies – built into what you already have.

Die Methode

How we build:
agentic coding
with Claude Code.

We develop AI-assisted – with Claude Code, one of the leading tools for agentic coding. In practice, that means a small senior team delivers in weeks what classic projects need months for. At a fixed price, in 3-week sprints, with no hourly-rate games.

And honestly: AI writes a lot of code for us – but no code goes live that an experienced developer hasn't reviewed and tested. The speed comes from AI. The responsibility stays with humans. How that looks day to day is in Agentic coding & Claude Code.

The proof

From 30 down to 3 minutes per order.

30 → 3Minutes per order

For a family-run e-commerce company, we rebuilt the order backend: processing time down from 30 to 3 minutes per order – minus 90%, across 30,000+ orders. That's not an optimization. That's a different company. Built with the tool that fit – not the most expensive one. Read the case study →

FAQ

We know the questions. Here they are – answered honestly.

“What does custom software cost?”

Most SCALE² sprints fall between €2,500 and €13,000 – a fixed price, agreed up front. Larger projects get split into several sprints, each with its own usable result.

“How long does it take?”

Three weeks per sprint. After the first sprint, something real is running in your business – not a concept paper, not a prototype that never ships.

„Having custom software developed – how does it work?“

In five phases over three weeks: analysis of your real process, a concept with a clear scope, AI-assisted development, testing alongside daily business, go-live with handover. What Claude Code costs a team – and how that compares to Codex and Cursor – is in our guide: Claude Code pricing explained.

“Who owns the code?”

You do. All repositories, access, and licenses run in your name. You can carry on with any other developer at any time – that's by design, not by accident.

“What about maintenance?”

Three weeks of support after go-live are part of the sprint – handover, documentation, and onboarding included. After that, it's your call: a maintenance agreement with us – or your team takes over. No mandatory retainer.

“Why not just use a standard tool?”

Often: exactly! If a standard tool or a Make.com automation solves your problem, that's precisely what we recommend – even though we earn less on it. We only build custom software where it measurably brings back more hours.

“Is AI-generated code safe?”

As safe as its review process. Our rule: every line passes review by an experienced developer, plus automated tests before every go-live. AI makes us faster – not sloppier.
