Quotes used to be assembled by hand from ERP data, price lists and emails. Today an internal tool produces the finished quote: checked, calculated, delivered as a PDF.
Costing tool + ERP integration
We build
what you need.
An internal tool that calculates quotes. Or a client portal connecting several locations. We develop digital solutions for the work your business does. The scope follows your needs and budget. That does not mean starting from scratch: we first check which existing software fits and how your current systems can be extended.
Every project starts with a sentence like this.

Diagnosis
Your systems are islands. Every bridge between them is currently a person with two screens: expensive, slow, and the main source of errors.
How we build it
We connect the systems through their interfaces, bidirectionally and fault-tolerantly. What used to be retyped flows automatically, with a log, so you can always see what was transferred when.
Outcome
Zero duplicate entry, no more transfer errors, and your people get back to their actual jobs.
Diagnosis
The spreadsheet was once a stopgap. Now costing, planning or scheduling depend on it. A file only one person truly understands is a business risk.
How we build it
We turn the spreadsheet into a small, robust application: same logic, but multi-user, with permissions, history and a connection to your real data. Your people recognise the process immediately.
Outcome
A tool instead of a wobbly spreadsheet. Everyone can work with it, nothing gets lost anymore.
Diagnosis
Standard software covers 90%. But the missing 10% is often exactly your competitive edge. Asking the vendor for features takes years. If they ever come.
How we build it
We build the missing 10% alongside it: docked on via interfaces or the database, without touching the industry software. Vendor updates remain possible.
Outcome
Your software finally does what your business needs. Without a risky system migration.
Diagnosis
The real problem is rarely the technology, it’s the order: which process pays off most when automated? What’s a quick win, what’s a bottomless pit?
How we build it
We run a digitisation audit: one day on site, your processes from order to invoice. You get a prioritised list: what pays off, what it costs, where to start.
Outcome
A plan with priorities instead of gut feeling. And a first step that pays for itself in weeks, not years.

What we do for you.
/01
Consulting & concept
We analyse your processes and tell you honestly what is worth digitising. And what isn’t. The result is a plan with priorities, effort estimates and sequence.

Why clients stay with us.
Principle 01
Buy software or have it built?
If an existing product fits the task, we recommend it. If a feature or a connection to another system is missing, we add what is needed. Custom software makes sense where your processes otherwise involve too many workarounds. We assess that with you before we build.
Principle 02
Fixed price, no surprises.
We discuss your budget early and agree what will be most useful first. That might be a single tool or an application used across several departments. After the analysis you receive a fixed-price proposal for the agreed scope and schedule. Larger projects can be planned in stages. We agree any additional work before it incurs costs.
Principle 03
Your code belongs to you.
You receive the source code and documentation for your application. The agreed usage rights transfer to you once payment is complete. Existing components remain subject to their own licences. Another development team can continue the work.
Principle 04
We stay on it.
Software is finished when it runs. And it only runs when it’s looked after. Monitoring, updates, evolution: from one team, the one that built it.
