Sync data with Visma eAccounting
Unified. Reliable. Secure.
Visma eAccounting is a cloud accounting platform widely used by SMEs and freelancers across Norway, the Netherlands, and Sweden - where it is called Spiris/Bokföring & Fakturering. The platform supports core bookkeeping processes such as invoicing, VAT handling, bank reconciliation, and financial reporting, with strong alignment to local compliance requirements across all three markets.
Integrate eAccounting alongside dozens of other accounting and ERP systems through Maesn Unified API.

OAuth 2.0 Done Right — Scopes, Tokens, and Multi-Tenant Auth Handled
eAccounting's OAuth flow requires precise scope declaration upfront, token refresh logic per tenant, and correct prompt and parameters. Maesn standardizes the entire flow: you register your app once, and we handle scopes, token refresh, and re-authorization automatically for every tenant.

Pagination That Actually Returns All Your Data
eAccounting returns 50 results per page by default. Without explicit pagination handling, your sync silently returns incomplete data. Maesn paginates all collection endpoints automatically, so you always receive the dataset without writing a single line of pagination logic.

VAT Codes and Account Mapping
VAT codes, account structures, and fiscal year references are tenant-specific and differ per country. Maesn handles this through a standardized integration configuration layer. This workflow is consistent across all supported systems and removes any country-specific or tenant-specific logic from your codebase entirely.
"Adding Qonto to our existing integrations was a piece of cake with Maesn. It is a game changer for our customers with all the integration cababilites!"

Why companies choose Maesn
3 Reasons why it is better to integrate Visma eAccounting API with Maesn

Secure & Compliant
We have a strong relationship to Visma. This ensures that the Maesn API is always up-to-date and any maintenance is covered on our end.

Common Data Model
We provide a clean, unified data model that abstracts away system-specific quirks, so teams can build reliable integrations without dealing with ERP-specific complexity or workaround-heavy implementations.

Visma eAccounting Sandbox
We provide you with everything you need, so you can focus on what counts.
Visma eAccounting is a cloud accounting platform used by SMEs and freelancers in Norway, the Netherlands, and Sweden. In Sweden, the same product is sold by Spiris (formerly Visma Spcs) under the name Bokföring & Fakturering. In Finland, Visma ePasseli runs on the same underlying API.
Yes. Spiris (formerly Visma Spcs) and Visma eEkonomi are the Swedish brand names for the same product. The API, authentication flow, and endpoint structure are identical across all markets. A name change does not require changes to your integration.
If a request fails, Maesn automatically responds with a corresponding error code. Further information can be found here.
You can monitor the status of your requests and resolve any errors using the Maesn Dashboard, which provides real-time observability and logs for better issue detection.
Setting up a Visma eAccounting integration from scratch through Maesn typically takes anywhere from a few days to a few weeks, based on the complexity of your use-cases. The greatest thing is, once the integration is implemented, you can access more than a dozen additional accounting integrations, including DATEV, Exact Online, Qonto and Sage.
Maesn uses HTTPS for all data transfer. All connections are secured using TLS with industry-standard, state-of-the-art encryption.
We don't store any of your customer data at Maesn to be 100% GDPR compliant - our platform is hosted at Microsoft Azure in Frankfurt, Germany.A direct integration requires building OAuth scope configuration, per-tenant token refresh logic, complete pagination handling, fiscal-year-scoped account lookups, and country-specific VAT mapping for Norway, the Netherlands, and Sweden. Maesn handles all of this out of the box through a single unified API that works the same way across eAccounting and every other system in the Maesn portfolio.
The most frequent blockers are: declaring the correct OAuth scopes upfront — missing one requires full re-authorization by your customer; handling 60-minute token expiry and silent refresh token invalidation on password change; building complete pagination logic since the API returns only 50 results by default; resolving fiscal-year-scoped account references before any write operation; and mapping VAT codes and account structures that differ per country and per tenant.
Yes. Maesn supports Visma eAccounting across all markets through a single integration. Country-specific differences in VAT codes, account structures, and API field availability are handled automatically by Maesn's integration configuration layer.
