When custom software makes sense
Many companies run critical processes in Excel sheets, email and several disconnected tools. That works – until errors, double data entry and missing overview start costing time and money. Custom software maps your exact process in one system, connects existing tools and gives everyone the same, current data.
Custom does not mean starting from zero: we combine proven frameworks, open-source modules and standard products (for example SAP or Microsoft 365) with tailored parts only where they create value.

Build, buy or extend?
We are honest about it: sometimes a standard product is the better choice. This is how we decide together.
| Option | Choose when… | Example |
|---|---|---|
| Buy standard software | Your process is standard and the product fits ≥ 80% | Accounting software, Microsoft 365 |
| Extend / integrate | A standard product fits, but needs connections or add-ons | SAP BTP extension, Shopify ↔ ERP sync |
| Build custom | Your process is your competitive advantage or no product fits | Production planning for a special manufacturing process |
| Low-code | Simple internal apps, quick wins | Power Apps, approval flows |

Frequently asked questions
Do we own the software?
Yes. You receive the source code, documentation and full rights to use and change it.
Can you connect our new system to SAP or DATEV?
Yes. We regularly integrate with SAP (OData, RFC/BAPI, IDoc), DATEV exports, Microsoft 365, shops and banking interfaces.
Cloud or on-premise?
Both. We recommend based on data sensitivity, existing IT and budget, and can host in Germany.
How do you avoid a failed IT project?
Small MVP first, two-week demos, clear acceptance criteria and early involvement of real users. You always see what you pay for.
