Moneybird is a leading cloud-based accounting software from the Netherlands, widely used by freelancers, small businesses, and SMEs. The platform simplifies invoicing, expense management, VAT handling, and bank reconciliation through a clean interface and strong local compliance coverage.
Integrate Moneybird alongside dozens of other accounting and ERP systems through Maesn Unified API.

Moneybird uses system-specific response structures, dedicated /filter endpoints and pagination without total page counts. Maesn abstracts all of it behind a clean unified REST API.
Every Moneybird request requires an administration ID resolved per customer after OAuth. Maesn stores and injects it automatically — no tenant-level ID management required on your end.
Moneybird provides a native sandbox environment. Maesn gives you access from day one so your team can build and test without a live customer instance.
Clockin helps small and mid-sized businesses digitize time tracking. From work hours to project times. User log everything via app or terminal, even offline, eliminating paper-based processes entirely.
"We use Maesn to successfully leverage integrations and partnerships as a key driver for lead generation and expansion into new markets and customer segments. By connecting Clockin to our customers' accounting systems, project data flows directly into their existing tools, ensuring a smooth, reliable data exchange with the systems they already use."

Moneybird uses system-specific response structures with format handling via .json and .xml endpoints. Maesn normalizes all responses to JSON and maps them to a common data model shared across every system connected through Maesn — no Moneybird-specific parsing or format handling required in your code.
JSON normalization across all endpoints
Common data model shared across all connected systems
No system-specific parsing logic required
Every Moneybird API request requires an administration ID in the URL path, resolved per customer after OAuth and required on every subsequent call. Maesn resolves and stores the administration ID per tenant during onboarding and injects it automatically on every request. No tenant-level ID management required on your end.

Moneybird requires a full OAuth implementation including authorization flow, token storage and token refresh per tenant. Maesn handles the complete token lifecycle centrally - your team authenticates once per customer and Maesn manages everything from that point forward.

Token storage and refresh managed per tenant
No auth logic required on your end
Moneybird uses dedicated /filter endpoints instead of standard query parameters and does not return total page counts — requiring iterative traversal to determine when results are exhausted. Maesn unifies both to a standard limit and page model and handles background page calculation automatically.

Moneybird's app directory requires a manual submission with formal technical requirements: at least 25 active connections, a minimum of two months live, OAuth with refresh tokens, correct rate limit handling and webhooks instead of polling. Maesn's architecture satisfies all technical requirements by default and supports you through the submission process.
Minimum 25 active administrations and 2 months live required
OAuth, webhooks and rate limit handling all required
Maesn supports submission
The Maesn docs cover every Moneybird endpoint, authentication flow and implementation detail, plus a full overview of the current coverage, which is continuously being expanded.

Moneybird is a Dutch cloud accounting platform widely used by small and medium-sized businesses in the Netherlands and Belgium for invoicing, expense management and financial administration. It offers an open REST API and is particularly popular in the Benelux market, making it a common integration target for software teams building accounting automation or multi-system financial workflows in that region.
A direct Moneybird integration requires handling system-specific JSON and XML response formats, dedicated /filter endpoints instead of standard query parameters, pagination without total page counts, OAuth with token refresh per tenant, administration ID management per request and rate limit handling at 150 requests per 5 minutes. Maesn abstracts all of this behind a unified REST interface — so your team builds once and reaches Moneybird and every other system Maesn supports without maintaining any of the complexity directly.

Yes. Moneybird webhooks are registered at the application level rather than per user. Maesn normalizes these to user-based payloads which are consistent with every other system connected through Maesn.
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.
