What is maesn?

maesn is a Unified API platform built in Germany that lets SaaS companies, fintechs and banks launch integrations with Odoo and more than 50 other European accounting and ERP systems in days instead of months. Instead of building and maintaining every integration yourself, you integrate once with maesn and reach an entire category of systems through a single, normalized data model: including DATEV, SAP, Microsoft Dynamics, Sage, Visma, Exact Online and, of course, Odoo.

Companies like Tipalti (US payables automation), Rally (Y Combinator), Findity (spend management) and Agicap (cash flow management) use maesn to offer their customers native accounting and ERP integrations without building them in-house.

Frequently Asked Questions

How do I integrate the Odoo API into my software?

Odoo's native API runs on XML-RPC and JSON-RPC rather than REST. maesn abstracts the entire RPC layer, session-based authentication and per-customer base URLs behind one clean REST interface. You build against the maesn Unified API once and reach every Odoo deployment. Details on the maesn Odoo integration page.

Do I have to build a separate integration for DATEV, SAP or Sage?

No. With maesn you do not build point-to-point connections. Your one integration with the maesn Unified API covers Odoo, DATEV, SAP, Sage, Visma, Exact Online and 50+ other systems through the same normalized data model.

Is this module free?

Yes. The module is free and open. The maesn platform itself is a commercial service with plans based on the number of connections and API usage.

Who is maesn for?

maesn is built for SaaS companies, fintechs, neobanks and banks that want to offer their customers native integrations with Odoo and other accounting and ERP systems, without building and maintaining each one internally.

Is maesn GDPR compliant?

Yes. maesn is developed and operated by maesn GmbH, based in Düsseldorf, Germany. The platform is ISO 27001 certified, fully GDPR compliant and hosted in the EU, and it supports regulatory requirements such as DORA for financial services customers.

Does the module change my Odoo data?

No. This module only adds a menu entry. Any data access runs through the maesn platform and is configured explicitly by you, with full control over scopes and connected systems.

Which Odoo versions are supported?
