Partner programme for system integrators and ERPs
You build and run the integration; Elyonar is your Access Point Provider. Connect once to the Yona Access Point API, and the invoices you submit for each taxpayer are validated, given their IRN and QR code, and transmitted to the NRS under our licence.
Live in production, with a sandbox to test first.

The Yona business app is built on this same API.
You build, host and support the e-invoicing integration for your clients or your own group. Elyonar is the licensed Access Point that carries it to the NRS.
System integrators
Deliver e-invoicing projects for your clients on an Access Point that is licensed and live.
ERP and accounting software vendors
Transmit the invoices your software already issues, for every customer, through one connection.
Enterprise IT teams
Run your own integration and reach the NRS through a licensed Access Point.
Banks, fintechs and marketplaces
Submit invoices on behalf of the businesses you serve, each with its own grant.
One API, one integration, every customer. The same API the Yona business app is built on.
Signing and transmission under our licence
Every invoice gets its reference number and QR code and reaches the NRS through Elyonar, a licensed Access Point Provider.
Many taxpayers, one integration
Each business you serve selects Elyonar as its Access Point and grants you access. You submit, track, receive and reconcile for all of them.
Receiving
Invoices that other access points send your customers arrive through the same API.
Buyer checks
Confirm a buyer is on the e-invoicing network before you submit.
Signed webhooks
Every status change is pushed to you and signed, so you can verify it came from us.
History import
Bring in a taxpayer's earlier invoices from the NRS.
Sandbox first
Build and test against the sandbox with test credentials before you go to production.
A partner portal
Your account and credentials, managed at partners.useyona.com.
Four steps. The sandbox is open from day one.
01
Apply as a partner
Sign up and complete KYB.
02
Build in sandbox
Integrate against test data with sandbox credentials.
03
Get approved for production
Elyonar reviews your account and issues production credentials.
04
Connect taxpayers and submit
Each business selects Elyonar as its Access Point and grants you access. Then you submit, track, receive and reconcile their invoices.
Partner pricing is agreed per partner, on volume and on how you serve your customers. Your customers never pay Yona directly unless you want them to.
The same licensed Access Point serves the Yona app and the API.
Yes, in one of two ways. To use Yona's invoicing inside your own systems, create a Yona account and build on the Yona API (see /developers). If you are a system integrator or ERP running your own integration, join the partner programme: sign up at partners.useyona.com, complete KYB, and connect to the Yona Access Point API; your customers select Elyonar as their Access Point and grant you access.
No. They enable e-invoicing on the taxpayer portal of the NRS, select Elyonar as their Access Point and grant your product access. The licence is ours; the integration is yours.
Yes. Sandbox credentials come with your partner account. The sandbox runs the real flow against the test system of the NRS, with no legal effect.
Partner pricing is agreed per partner, on volume and on how you serve your customers. Talk to us and we will set it up with you.
Every webhook delivery is signed. Verify the signature, then read the current state through the API before acting on it.
Sign up on the partner portal, build on the sandbox, and go live when you are ready.
