Integrations
API integrations for payroll, HR and accountancy
We have built integrations with the most widely used payroll, HR, accountancy and reporting packages in the Netherlands: Nmbrs, Loket.nl, Silverfin, Visionplanner and FiscaalGemak. Every integration has been tested in production with real administrations.
Nmbrs integration
SOAP API · REST API · Reports
The package we have the most experience with. From an open source SDK that makes the SOAP API accessible to every Python developer to custom integrations that process thousands of mutations every month.
What we have built
Open source Nmbrs SDKs in Python for the SOAP API (nmbrs) and the REST API (nmbrs-rest-api), free to use for fast and reliable integrations
Payroll Check Tool: 100+ control points on the administration in Nmbrs
Automatic pension filings from Nmbrs data, combined with Microsoft 365
Loket.nl integration
REST API · Documents
Firms switching from or to Loket lose a lot of time on documents and employee data. We built conversion tooling that takes over that work.
What we have built
Web application for document conversion from Loket to Nmbrs
Export of employee and employment data for migrations
Completeness and consistency checks after migration
Silverfin integration
Silverfin API
Figures and tax returns from the Silverfin file no longer have to be transferred by hand. The integration retrieves them automatically and submits them to the Dutch Tax Administration.
What we have built
Built for an accountancy software vendor: retrieving figures and tax returns from the Silverfin file
Automatic submission to the Dutch Tax Administration from the accountant portal
No more manual exports or retyping
Visionplanner integration
Visionplanner API
Retrieve tax returns, signing dates and other file data from Visionplanner automatically, present them clearly and submit them to the Dutch Tax Administration.
What we have built
Built for an accountancy software vendor: tax returns, signing dates and more straight from Visionplanner
Presented clearly in the accountant portal
Automatic submission to the Dutch Tax Administration
FiscaalGemak integration
FiscaalGemak REST API · Webhooks
New tax returns and status changes in FiscaalGemak no longer have to be copied over by hand. Through FiscaalGemak's webhooks they arrive in the accountant portal automatically, with statuses kept in sync on both sides.
What we have built
Built for an accountancy software vendor: integration between the accountant portal and FiscaalGemak
New tax returns delivered to the portal via webhooks, statuses synchronised
Knowledge of FiscaalGemak's REST API, authorisation, portal and webhooks
Microsoft SSO
Microsoft Entra ID · OAuth2 / OpenID Connect
Users sign in with the Microsoft account they already have. No extra passwords, but central management of access and permissions via Entra ID.
What we have built
Microsoft Single Sign-On (Entra ID) built for the platform of an accountancy software vendor
OAuth2 / OpenID Connect integration with role and permission management
Secure access for firms and their staff, without extra accounts

If there is an API, an export or even just a file exchange, we can integrate it. Integrations with AFAS, Exact and Twinfield, for example, are built on request.
