Sync data with sevdesk
Unified. Reliable. Secure.
sevdesk is a cloud accounting platform for SMEs and freelancers in Germany and Austria. It covers invoicing, expense management, contacts, and financial accounting with support for German GoBD compliance. The API is REST-based with token authentication and is available from the Buchhaltung Pro plan. Tokens have an infinite lifetime and are tied to a specific user account.
Integrate sevdesk alongside dozens of other accounting and ERP systems through Maesn Unified API.
Infinite-Lifetime API Tokens Tied to User Accounts: Token Deletion Risk on User Removal
sevdesk API tokens do not expire. They are tied to a specific user account and exist as long as that user exists. If the user is deleted, the token is permanently lost with no recovery path. For multi-tenant SaaS products, this creates a specific risk: if a customer removes the sevdesk user whose token powers the integration, the connection breaks silently. Maesn documents this constraint clearly during onboarding and handles token storage securely per tenant.
German GoBD and SKR Accounting Standards: Chart of Accounts Mapping Required Per Tenant
sevdesk is built for the German market and supports GoBD-compliant document management and German chart of accounts structures. Voucher and posting operations reference account codes that are tenant-specific. Maesn handles German account code mapping through its integration configuration layer, applying the correct codes per tenant automatically.
API Available on Paid Plan Only: Buchhaltung Pro Required in Germany
The sevdesk REST API is only available from the Buchhaltung Pro plan in Germany (system version 2.0). Customers on lower plans cannot access the API. Maesn's onboarding flow communicates this requirement clearly so your customers are guided correctly from the start.

sevdesk is a cloud accounting platform for SMEs and freelancers in Germany and Austria. It covers invoicing, expense management, contacts, and financial accounting with GoBD compliance. The API is REST-based with token authentication and is available from the Buchhaltung Pro plan.
The main challenges are managing infinite-lifetime tokens that are tied to specific user accounts and lost permanently if the user is deleted, mapping German chart of accounts codes per tenant for posting operations, ensuring customers are on the Buchhaltung Pro plan before attempting connection, and structuring vouchers and postings in GoBD-compliant format.
sevdesk API tokens do not expire by design, which simplifies implementation but creates a specific risk: the token exists only as long as the user account it belongs to. If the user is deleted from sevdesk, the API token is permanently gone with no recovery. For a multi-tenant SaaS product, this means a customer who removes the connected user account will lose API access with no automated recovery.
GoBD (Grundsätze zur ordnungsmäßigen Führung und Aufbewahrung von Büchern) is the German regulation for maintaining and storing accounting records. sevdesk is GoBD-compliant, which means documents and postings must meet specific requirements for format, audit trails, and immutability. Integrations that write data to sevdesk must respect these requirements.
A direct sevdesk integration requires managing infinite-lifetime tokens with deletion risk, mapping German account codes per tenant, handling the Buchhaltung Pro plan restriction, and ensuring GoBD compliance in all write operations. Maesn handles all of this through a single unified API.
