Who is this for?
Especially for small and mid-sized businesses: you get professional software without a big investment, without your own IT staff and without long contract commitments. Whether 3 people in the trades or 50 in consulting – the system grows with you.
How safe is my data?
With us, all data is stored exclusively on German servers – under the strict requirements of the GDPR. Encryption, daily backups and a data processing agreement (DPA) are standard. If you switch or cancel, you get your data back in open formats.
Recognise these situations?
Twelve typical problems from the everyday life of small businesses – and how we solve them concretely with tailored software.
Industry solutions that work.
Six industries, six concrete problems, six proven approaches.
Trades & construction
Measurements on paper, quote in Word, invoice in Excel – nothing connects.
Our solution: Capture measurements via photo, transfer them automatically to quotes, convert into invoices with one click. Material management and time billing directly linked.
Service providers & consultants
Appointments in Outlook, hours on slips, invoices forgotten – time evaporates.
Our solution: Appointments, time tracking, and invoicing in one flow. Online booking for customers, automatic reminders, invoices with DATEV export.

Hospitality & hotels
Reservations by phone, orders on paper, staff planning in your head.
Our solution: Online reservation with table/room occupancy, digital order processing, shift planning with time billing.
Standard software doesn't fit your processes?
Let's talk about a solution built exactly for your business. Free and non-binding.
Tailored. Not off the shelf.
We don't believe in off-the-shelf software packages. Every business is different – and the right software adapts to your processes, not the other way around.
Standard forces compromise
With ready-made standard software, your processes have to bend to the software, not the other way around. What doesn't fit becomes a permanent crutch – or isn't done at all.
We build your workflow
You show us how you work today and what should be different. From this we build a solution that does exactly that – and nothing you don't need.
Ownership model on request
On request you receive the full source code with documentation. You're not dependent on us – we want you to stay because you choose to.
How your software is built – in five steps.
From the first conversation to ongoing operation we accompany you personally. You have a dedicated point of contact – no rotating project team.
Workshop
1–2 daysWe get to know your business. Processes, pain points, wishes – honest and concrete, on site or digital.
Concept
1–2 weeksYou receive a binding fixed-price offer with a module plan, timeline, and a clickable prototype.
Development
4–16 weeksWe develop in two-week sprints. You see every step of progress live and can give feedback continuously.
Go-live
1–2 weeksData migration, training, soft launch. We stay until everything runs smoothly – including an on-site visit.
Operation
OngoingHosting, updates, support, further development – all from one source. You focus on your business.
Honestly: we're not a fit for everyone.
Instead of generic promises, we give you a clear orientation on whether custom software is really the right tool for you.
When custom software makes sense
- ✓Your processes are industry-specific or unique
- ✓You've already tried standard software – without success
- ✓You need custom interfaces (DATEV, ERP, POS, …)
- ✓You're growing and standard licenses are getting too expensive
- ✓You don't want to depend on the vendor (avoid vendor lock-in)
When not – honestly
- —When an existing standard covers 80% of your processes
- —When you have to start tomorrow (standard goes live faster)
- —When you don't have 4–6 weeks for a pilot module
- —When you have only 1–2 users
- —When requirements change fundamentally every week
In these cases we deliberately recommend ready-made standard software – and on request we support you in selection and rollout.
Hosting on German servers, GDPR compliant, monthly cancellable after 12 months minimum term.
