Integrations for the European market


In collaboration with our e-invoicing and payment transfer partner OpenText, we offer a ready-made solution for small and medium-sized companies looking to internationalise. This solution is designed for the European market and we offer it through the purchase and sales invoice solutions of Heeros. Our solution supports transfer formats defined in the EU's e-invoicing standard, such as Finvoice 3.0, TEAPPS 3.0 and PEPPOL.


APIs, or Application Programming Interfaces, serve as collaborative interfaces connecting software systems. Through these interfaces, data seamlessly moves from one system to another, formatted in a way that each software can interpret it. This dynamic, real-time automation of data transfer not only streamlines information processing but also significantly boosts the efficiency of financial management operations.

For sales invoices, we provide a JSON REST API , allowing you to import sales invoices created in another system into Heeros for billing or direct processing by the sales ledger.

Our APIs for purchase invoices enable the import and retrieval of purchase invoices, posting details, various registers, as well as images and attachments from external systems.
