How the Electronic Invoicing System BIR (EIS) Works in the Philippines
The BIR Electronic Invoicing System (EIS) automates how businesses report their sales invoices and receipts to the Bureau of Internal Revenue. It ensures every transaction—including those required under BIR eSales—is digitally recorded, securely transmitted, and properly validated for compliance.

A company issues a sales invoice, official receipt, credit note, or debit note. Each document must follow BIR’s required format and include key details like the document number, issue date, UIN, and seller–buyer information.

The system converts the invoice details into a JSON file, which is the format required for electronic transmission through the EIS platform.
Step 3: The File Is Digitally Signed and Sent to BIR
A JSON Web Signature (JWS) is applied to verify authenticity. The signed file is then transmitted to the BIR via the EIS API, and businesses must submit it within three days after issuance.
Step 4: BIR Validates and Returns the Status
The BIR checks the submitted data and responds with an acceptance or rejection. If rejected, the business must correct and resend the document to remain fully compliant.
