bexio is a cloud-based accounting and business software platform widely used by SMBs and fiduciaries in Switzerland, offering tools for invoicing, bookkeeping, contact management, and more.
Integrating via Maesn eliminates all bexio-specific complexity. ID mapping, synthetic webhooks, and all bexio-specific implementation details are handled automatically behind one unified API. Plus, you immediately gain access to dozens of other accounting and ERP systems.
bexio uses numeric IDs instead of named object types throughout its data model. For example, a contact is not labelled as "customer" or "supplier", it is identified by a numeric type ID. Maesn resolves and maps all these IDs automatically into the Common Data Model, so you work with clean, named objects without any bexio-specific lookup logic.
bexio does not offer webhooks natively. Maesn fills this gap with synthetic webhooks, covering every object and every event in a normalized payload, consistent with every other system in your stack.
bexio uses OAuth for standard integrations and OpenID Connect for marketplace-listed apps. Maesn supports both authentication flows, so your integration is ready for direct use and bexio App Marketplace listing without any additional auth implementation.

Maesn uses HTTPS and TLS for all data transfer and does not store any customer data. The platform is hosted on Microsoft Azure in Frankfurt, Germany, and is fully GDPR & ISO 27001 compliant.
