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.

Payroll

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

Payroll & HR

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

Accountancy

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

Reporting

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

Tax

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

Identity

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.
