Compliance & Credentials
We don't claim credentials we don't have. Here is exactly what BlackZero holds, what your business holds, and what the difference means for your CAS registration and EIS obligations.
What your business holds
These credentials are issued to your business — not to BlackZero. They are specific to your TIN and your registered accounting system.
BIR issues the AC to your business after evaluating your CAS registration packet. It certifies that your specific accounting system has been reviewed and approved. BlackZero generates the registration packet; your business submits it to your RDO and receives the AC.
After your AC is issued and EIS pipeline testing is complete, BIR issues the PTT. This authorizes your business to transmit live e-invoices via your registered ASP (BlackZero). Transmission before PTT issuance is not permitted.
What BlackZero holds
These credentials are held by BlackZero as the service provider. They authorize BlackZero to operate the EIS transmission infrastructure on your behalf.
Accredited Service Provider status authorizes BlackZero to transmit e-invoices to BIR on behalf of registered taxpayers. This is the credential that enables the EIS pipeline. Without ASP accreditation, a software vendor cannot legally transmit EIS data to BIR.
Electronic Taxpayer Service Provider certification is a separate BIR designation for providers operating e-invoicing infrastructure. BlackZero is pursuing eTSP certification. Current status: application submitted — expected Q3 2026. We will update this page when certification is issued.
The process
From registration packet to live transmission — the six steps and who is responsible for each.
BlackZero generates your complete Annex A-1, A-2, A-3, sample invoice, and system guide from your business profile. Takes under 10 minutes.
Your BOA-accredited accountant reviews and co-signs the Annex A-2. The taxpayer (you or an authorized signatory) signs the Sworn Statement.
The complete packet is submitted to your Revenue District Office. BlackZero provides a submission checklist and cover memo template.
BIR reviews the Annex B technical requirements against your submitted documentation. RDO processing timelines vary. BlackZero tracks status in your dashboard.
BIR issues the AC to your business. Your AC number is entered into BlackZero to activate the EIS pipeline configuration.
After AC issuance, BlackZero guides the PTT application. Once PTT is issued, live EIS transmission begins automatically. Every invoice is transmitted within the 3-day window.
Our commitment
When our accreditation status changes, this page updates first. The Compliance page is the source of truth — not marketing copy. If a credential is pending, we say it is pending. If a credential is held by your business rather than by us, we say so plainly.
This page is designed to be cited. The URL is stable. Every credential status has an anchor link. If you need to reference BlackZero's compliance posture in a client engagement or an RDO meeting, you can link directly to this page.
