Initial Situation
Manual Excel processes for order management and warehouse — 3 full-time staff occupied daily with data entry.

70% time savings in order processing, 2 full-time positions freed for value-adding tasks, error rate reduced to zero.
Off-the-shelf software never fits 100% — yet still costs a lot
- Every business has unique processes — standard software forces compromises that slow your team down every day
- License costs grow with your team: what costs €500/month today becomes €5,000 tomorrow
- Integrations with SAP, DATEV, or existing systems are missing or cost extra as add-ons — always
Custom software that fits your exact process — a one-time investment with lasting advantage
- Built for your requirements: no feature bloat, no license traps, no compromises on core processes
- Native SAP and DATEV integration plus connectors to all your systems — included in the fixed price
- Fixed-price quote after the discovery workshop: you know the cost before a line of code is written

Our Approach
How we work

UX & Architecture
Clickable prototype and technical architecture for validation before a line of code is written — you see the product before it is built.
Agile Development
Development in 2-week sprints with working demos. No status reports — you see real software.
Launch & Handover
Deployment on EU servers, acceptance testing, employee training, and complete documentation.

Is this right for me?
An honest assessment — before you call us
Custom software is not the right solution for everyone. We would rather tell you in advance whether we are the right partner — than waste your time.
Good fit
- Companies with 20–500 employees with clear digitization goals
- Manual processes (Excel, paper, email) that need to be automated
- Existing systems (SAP, DATEV, ERP) that need a modern interface
- Budget from $15,000 — you know the value of custom software
- You can provide an internal point of contact for the project
- You want a real product — not a PowerPoint prototype
Probably not the right fit
- Startups that need an MVP for under $5,000
- Projects without a defined business process in the background
- "Some app" without a concrete use case or target audience
- Those who cannot name an internal point of contact for the project
- Those who cannot or will not make decisions (too many approval levels)
None of these apply? Then we are probably a great team.
Frequently Asked Questions
Everything you need to know about App Development at a glance.
01What does custom app development cost?+
A simple web portal starts at €15,000 fixed price. More complex applications with SAP integration typically run €40,000–120,000. After a free discovery workshop you receive a binding fixed-price quote within 5 business days.
02How long does development take?+
For standard business applications we plan 8–16 weeks from kick-off to production version. In 2-week sprints you regularly see working versions — no black box, no waiting for the grand finale.
03Can you integrate our existing systems (SAP, DATEV, ERP)?+
Yes. SAP S/4HANA, SAP Business One, DATEV, and other ERP systems are standard for us. We identify the required interfaces in the discovery workshop and include them in the fixed price — no surprise surcharges after project start.
04Where is the data hosted?+
Always on EU servers (Hetzner, IONOS, Azure EU region). Your data never leaves the EU — GDPR compliance is not an add-on, it is our standard.
05What happens after launch — who handles updates and bugs?+
We offer SLA-based support from launch: response time <4 hours for critical issues, monthly maintenance windows, and regular security updates. Ongoing development in running sprints is available anytime.
06Can we split the project into phases to limit risk?+
Yes, and we recommend it. We start with an MVP (Minimum Viable Product) covering the most important processes — typically ready in 8–10 weeks. Real user feedback then feeds into phase 2. This reduces risk and secures ROI early.
Free Assessment Workshop — no commitment
