Custom Software & Integration

Sooner or later standard software runs into its limits: a process needs an exception, two programs should exchange data, a report is missing. That is when we build exactly the piece that was not there. Written in whatever language suits the job, and maintained for years afterwards.

When standard is not enough

Custom development and interfaces

From a single web application to a chain of connected systems: we build the piece you are missing and fit it in properly. We write new code where it pays off; what already works stays.

Custom web applications built to your process
If nothing on the market fits, we build the application that mirrors your actual process: a customer portal, an internal tool, a report. We choose the technology to suit the job, so that it stays maintainable.
System integration and API work
Two systems that know nothing about each other mean double entry and mistakes. We connect them through their interfaces (APIs), for instance an inventory system to a shop, so that data moves once instead of being typed twice.
E-commerce connections and automation
A shop only earns its keep once orders carry on into the rest of your systems without a detour. We connect it and automate the path from order to invoice. Whether Shopify, Shopware or something of your own, we work with what you already use.
E-invoicing (ZUGFeRD, XRechnung)
Since 2025, German companies must be able to receive electronic invoices. We handle the formats, ZUGFeRD and XRechnung, and connect them to what you already run, so that invoices arrive where they belong.
Scripts and automation for recurring work
Recurring chores such as exports, data comparisons or reports can be done by script. We automate what pays off, so that nobody loses time copying and pasting between programs.
Maintenance and further development over years
After go-live we stay involved: we maintain what we build, fix faults and develop it further when your processes change. That way the application grows with your business.

How it works

First the process, then the code

Understand the need

Where the process sticks and which systems should work together.

Build

Custom applications and interfaces, written to be maintained.

Connect and automate

Inventory, shop and the rest mesh, and the manual work goes away.

You stay free to leave

Anything we run on a monthly basis can be cancelled monthly: hosting, mailboxes, SEO work, managed servers. If you decide to move on, we release the domain and hand over your data. We would rather earn your staying than lock it in.

What should be talking to what?

Describe the process and we will look at the interfaces.
