Managed compliance infrastructure
Traxion carries the engineering load
Your team should not have to become experts in EIS schemas, cryptographic signing or transmission retry logic. We operate the layer between your source systems and BIR, with every event visible in one console.

Field mapping
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.
Pre-validation
Catch schema, arithmetic and certificate issues before they become BIR rejects.
10-year archive
Preserve payloads, acknowledgements, errors and repair history for examination.
Retry & reconciliation
Track the reporting window that applies to you, replay safely and prevent duplicate filing.
Certification support
Evidence pack, Annex B matrix and guided preparation for BIR testing.

Cut over & operate
After your Permit to Issue is granted, complete a shadow run and move to live electronic-invoice issuance with monitoring and support.
TRAXION SETUP · 2–5 DAYSBefore you can issue
Electronic invoicing starts with a Permit to Issue from the BIR. Reporting your sales data to the Bureau is a separate obligation with its own permit, and it starts only when the BIR issues its implementing guidelines and tells you so. We get you ready for both and hold the second one dormant until your notice arrives.

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 Permit to Issue and, when BIR activates sales reporting for you, the Permit to Transmit and EIS Certification. 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. A CAS Acknowledgement Certificate or Permit to Use covers how you keep your books and run your system. Issuing electronic invoices needs a separate Permit to Issue from the BIR. Reporting sales data to the Bureau later needs a Permit to Transmit, which the BIR issues only when it directs you to start reporting.
You need both, and an inactive AC will cause EIS to reject your payloads.
What is a Permit to Issue and how long does it take?
It is the BIR's authority for you to issue electronic invoices, and it is separate from your CAS permit. You apply to the Bureau, which evaluates the application within twenty working days. Once your permit is granted you have six months to complete EIS Certification. We prepare the technical evidence the application asks for and track both dates against your account, but the permit is issued to you and the application is yours to file.
When do we have to report a sale to the BIR?
Not yet. Under RMC 98-2026, electronic sales reporting begins only once the Bureau issues its implementing guidelines and notifies you directly. Until that happens you issue electronic invoices and nothing is transmitted. When your notice arrives, we record it against your account and start measuring the reporting window the Bureau sets for you.
Can we amend an invoice after issuing it?
No. An issued electronic invoice is never edited or deleted. To reduce an amount you issue a credit note against it. To increase one you issue a new electronic invoice. The platform enforces both, so the original document and its correction stay linked and auditable.
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 Platform; you sign, and we handle BIR reporting once it is activated for you.
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.
