greenfield translates tax requirements into technical and operational processes. The partnership combines this expertise with ecosio’s e-invoice validation: ecosio provides the technical basis, and greenfield adds the tax checks.
With ecosio, we have a technology partner that provides a scalable validation solution. We bring the tax expertise and make sure invoices are technically valid and correct from a VAT perspective.

Different e-invoicing and e-reporting requirements make international projects complex. greenfield needed a reliable technical basis covering multiple countries and formats that it could combine with its own tax checks. A technically valid invoice must also contain correct data. The partnership also needed to go beyond referrals. Direct access to specialists and an open exchange of knowledge were important to greenfield.
Our work with ecosio goes well beyond leads and referrals. What matters is the direct exchange of technical knowledge and tax expertise between equals. That’s what makes the partnership valuable to us.
greenfield builds greenvoice on ecosio’s API-based e-invoice validation. ecosio provides the technical foundation and checks format and business rules. greenfield adds its tax expertise by checking VAT content and process logic. This allows greenfield to scale its testing without building its own technical validation.
The partnership began with joint marketing activities before expanding into technology and implementation. ecosio supplied the API credentials; greenfield completed the connection itself and integrated the validation into its work with greenvoice.
For France and countries using Peppol, greenfield was able to develop a test data set quickly and use ecosio to check whether the invoices it contained met the technical requirements.
The connection was straightforward. ecosio gave us the API credentials, and we were able to add the validation directly to our work. That practical approach is typical of the partnership.
Test invoices with deliberate errors show whether client systems identify and handle issues correctly. For incoming invoices, greenfield creates test invoices with deliberate errors and makes them available to clients. This shows whether client systems identify and handle issues correctly (greenvoice.IN).
For outgoing invoices, greenvoice.OUT supports implementation projects: e-invoices generated by clients are validated through ecosio. In addition, greenvoice.OUT performs its own quality checks on how the EN 16931 fields are populated and whether VAT requirements are met.
Regular contact with ecosio’s partner management team and direct access to product specialists support further joint development.
With the ecosio API, I didn’t have to implement, host or maintain the validation myself. I also have access to extensive validation options for different formats. This gives us a dependable technical basis on which we can build further tax checks.
