Three steps. Zero exports.

From question to action — without leaving your AI tool.

01 — Connect

We handle the technical setup

Maesn’s team configures your ERP connection, authentication, and access permissions. Guided, fully managed, no internal dev resources required.

02 — Configured for you

Your systems, your data, your team

We map your specific ERP structure, define access boundaries per team or user, and ensure data flows securely through the Maesn API layer.

03 — You bring the questions

Start acting on your data

Your team opens Claude and asks. Pull reports, reconcile entries, write bookings — all in plain language, directly inside the AI tool you already use.
