Philippines BIR E-Invoicing (EIS) Integration

Section 237-A of the Philippine Tax Code, introduced by the TRAIN Law, requires electronic invoicing and electronic reporting of sales data to the BIR for specific taxpayer groups. Coverage started with:

• Taxpayers engaged in the export of goods and services.
• Taxpayers engaged in e-commerce.
• Taxpayers under the jurisdiction of the Large Taxpayers Service.

The BIR onboards covered taxpayers in phases, and later legislation (including the Ease of Paying Taxes Act) updated invoicing rules. Confirm current coverage and timelines with the BIR's latest regulations.

The EIS is primarily an electronic invoicing and sales data reporting system. Your system issues the invoice to the buyer and transmits the invoice and sales data to the BIR EIS, which acknowledges receipt. Unlike a strict clearance model, the invoice is not held back waiting for approval, but transmission must be complete, accurate and timely.

Before production, the taxpayer's system goes through registration, testing and certification steps defined by the BIR.

• Structured JSON payloads following the EIS data specification.
• Security: signing and encryption of transmissions and secure credential management.
• Identifiers: seller TIN, branch codes and registered system details.
• Tax data: VATable, zero-rated and exempt sales breakdown, discounts and totals.
• Acknowledgements and logs retained as proof of transmission.

We add a transmission service beside your ERP or POS. It collects issued invoices, builds and signs the EIS payloads, sends them through the BIR API, records acknowledgements and alerts your team about failures. One service can handle multiple branches and source systems, with a dashboard showing what was sent and what still needs attention.
