System Integration & APIs in Braunschweig

Your systems don’t talk to each other? That costs you time every day.

Your inventory system runs separately from your online shop. Invoices are manually entered into accounting. Customer data exists in three different systems. Orders travel from A to B via CSV files or copy-paste.

Every manual connection costs time, creates errors, and frustrates your team.

I build the connections so your data flows automatically.

What you get

• Automatic data transfer — orders, customer data, or invoices flow from one system to another without anyone typing anything
• Connection to your systems — JTL, Xentral, Billbee, Lexoffice, DATEV, SAP, or other software you already use
• Online shop integration — your shop and inventory system are always in sync
• Fewer errors — no more typos, no forgotten entries
• Clear documentation — so you know what was built and how it works

Clear fixed price per project

Every project — whether a single connection or a complete solution across multiple systems — gets a fixed price we agree on upfront. No surprises, no open-ended hourly billing. You describe your systems, and I give you the scope and the price.

Typical projects

• Automatically transfer online shop orders into JTL or Xentral
• Send invoice data automatically to DATEV or Lexoffice
• Sync customer data between CRM and email marketing
• Automatically import supplier data instead of using CSV files

Why me

I’ve spent 12+ years building software systems that reliably process millions of records. At FlixBus and GetYourGuide, I developed complex system integrations. I now bring that experience to businesses in Braunschweig and the surrounding area — just explained more simply.
