Why custom
Copying data between systems isn't work. It's a risk.
An order gets retyped into accounting, a web lead into the CRM, stock levels into the online store. By hand or through an Excel export. Every transfer takes time, and sooner or later someone makes a mistake.
Manual retyping and exports

- ErrorsTypos and forgotten records
- OutagesYou find out when something's missing

A to Z
Data map first. Then the connections.
Every integration starts with three questions: where the data comes from, who owns it and what happens when a connection drops.
Analysis and data map
We go through your systems, their APIs and data flows. We decide which system is the source of truth for which data.API design
We design the interface, permissions and data format. You get the documentation before any coding starts.Development and testing
We build the connections, data mapping and error handling, then test everything on a copy of your real data.Monitoring and maintenance
We monitor every integration. When a partner changes their API, we update the connection.Examples
Every one different. Every one custom-built.
