BIR Electronic Invoicing System (EIS), 12% VAT and ATP-bound receipts: validation acknowledgements for Philippine business
The Bureau of Internal Revenue (BIR) administers the Electronic Invoicing System (EIS) under the TRAIN Law (RA 10963). The largest taxpayers in the Philippines have been onboarded since 2022 and the rollout is widening to the rest of the economy. Every covered taxpayer must transmit sales invoices and official receipts to the EIS within the cut-off, with the 12% value-added tax broken out per line. 4notify wires into Philippine accounting stacks and delivers acknowledgements, validation states and routed notices to the right accountant.
Whereas, pursuant to the National Internal Revenue Code (RA 8424) as amended by Republic Act No. 10963 (TRAIN Law) and the BIR's regulations on the Electronic Invoicing System, the present Diaryo is issued on the delivery of acknowledgements and validation reports for electronic invoicing.
Foundation of the Electronic Invoicing System and the 12% VAT regime.
Technical specs for EIS transmission, ATP bindings and document-control numbers.
Accounting webhook
4notify subscribes to the electronic-invoice queue of the ERP or accounting software; validation runs before the document is transmitted to the BIR.
Acknowledgement + validation report
Acknowledgement to the issuer within 60 seconds; validation state (accepted / accepted with notes / rejected) within five minutes.
Routed to the right accountant
With the accountant's TIN, the acknowledgement is routed to the responsible professional.
Ten-year custody
Each invoice and acknowledgement is retained with a signed hash for ten years, matching the BIR's retention rule.

- ERP / accounting webhook configured
- Invoice validated at the API edge before BIR transmission
- Acknowledgement P50 ≤ 60 seconds measured
- Ten-year custody documented for BIR audits
4notify is the only A2P provider with native integration to Philippine accounting stacks, EIS validation at the API edge and a signed ten-year audit trail matching the BIR's retention rule.
Does 4notify need the BIR EIS credentials?
No. 4notify handles the acknowledgement envelopes that the accounting software emits; the BIR EIS connection itself stays inside the taxpayer's own stack.
What if the taxpayer is not in the EIS-covered tranche yet?
Even outside the EIS scope, 4notify handles the local sales-invoice / official-receipt acknowledgement to the buyer and to the accountant, ready to switch on EIS transmission once the taxpayer is onboarded.
