Build · Integrations & APIs
Make your systems talk to each other.
CRM, ERP, shop, payments and AI agents connected, so data is entered once and arrives everywhere.
Who it is for
Sounds familiar?
For companies whose systems do not talk to each other.
- Orders, contacts and invoices are copied by hand between tools.
- E-invoicing in Germany becomes mandatory for B2B and the ERP is not ready.
- Every new tool means another login and another export.
- AI agents cannot reach the data they need.

FAQ
Questions we hear often.
When do German companies need e-invoices?
Receiving e-invoices in B2B has been required since 2025, and issuing them becomes mandatory in stages until 2028. We set up XRechnung or ZUGFeRD in your current tools.
What if a system has no API?
We look for export interfaces first. If there is nothing, a software robot (RPA) can work with the old system, see Automation.
What is an MCP server?
A small service that lets AI agents use one of your systems in a controlled way: which data they see and which actions they may take.
