Convert your ERP, CAS, POS or storefront data into the current EIS schema.

Secure signing

JWS signing and AES-256 transport using keys protected inside an HSM.

Straight answers

Questions we get in the first call

Clear ownership, clear limits and no compliance theater.

Does using Traxion make us compliant?

It makes you capable. Compliance stays with you: you hold the EIS Certification and the Permit to Transmit, and the Bureau examines your records. What we remove is the engineering and the archive — the two things that make most projects slip past the deadline.

We already have a CAS Acknowledgement Certificate. Is that enough?

No. They are separate approvals. A valid CAS permit covers how you keep books and issue invoices; EIS Certification and the PTT cover transmitting sales data to the Bureau. You need both, and an inactive AC will cause EIS to reject your payloads.

How long do we have to transmit an invoice?

Three calendar days from the transaction. Our queue counts down per document and escalates at day two, so a stalled integration surfaces while you can still fix it. For B2C the transaction is normally recognised on payment; for B2B it may be delivery rather than payment, which is a mapping decision we make with your tax team during stage 03.

What happens to an invoice the EIS rejects?

You see the Bureau's error code and the offending field in the console, with the document held in a repair queue. Most rejects are schema errors (a missing mandatory field, or an extra one) or a signature problem from an expired certificate. Our pre-transmission validation catches the large majority of both before they leave the gateway.

Can we split a mixed VATable and exempt sale on one invoice?

The EIS expects them separated by tax classification, so a sale with both becomes two e-invoices. The gateway performs the split and links them under a common source reference, so your ledger still reconciles to one sale.

Who holds the signing key?

The private key sits in our HSM and never leaves it, issued under a certificate bound to your taxpayer identity. If you prefer to hold your own key, bring-your-own-certificate is supported on Enterprise and National; you sign, we transmit.

What if we leave?

You take a full export: original JSON, JWS artefacts, BIR acknowledgements, and transmission logs, in the structure the Bureau examines. Nothing about the archive is proprietary to us. We keep a copy only for as long as your contract requires.
