About

Maesn is a Unified API for ERP and accounting integrations. Software teams build one integration to Maesn and connect to DATEV, SAP, Sage, Microsoft Dynamics 365, Exact Online, Lexware, sevdesk, Xero, Odoo, Fortnox and 30+ more systems through a single REST API. Maesn unifies authentication (API keys, OAuth, database credentials, 2FA), pagination and filtering, webhooks, logging, monitoring and error handling, and normalises responses into a common data model for invoices, journal entries, contacts, payments and more. Custom fields are mapped into one schema, and synthetic webhooks cover systems without native ones. SDKs, sandboxes and quickstarts are available for Python, JavaScript, PHP, Go, Ruby and Java. Integrations run white-label under your brand, including certified marketplace listings and an embedded auth flow. Maesn is built and hosted in Germany, ISO 27001 certified, GDPR compliant and DORA-ready, and processes API calls in real time without storing customer data.

Pros & Cons from Real Users

Pros

  • - Fast and straightforward implementation; our engineer got it running quickly and mentioned how smooth the setup process was. - The dashboard with full logging is a big win. It gives us great visibility and helps us debug or monitor integration issues easily. - What really stands out is the team: we’ve had a direct line to the CEO and felt that they genuinely care. They’ve been very open to feedback and actively working with us on connector improvements.
  • Connectivity and ease of integration to existing systems. Support multiple accounting softwares with good coverage.

Cons

  • Some connectors (e.g., for HRIS systems) are still missing a few endpoints we’d like to see. That said, the team is transparent about it and open to prioritizing additions based on our needs.
  • They still need to work on integrating stripe and payments.
