Zoho Books e-Invoicing in the Philippines: Frequently Asked Questions

1. What is Philippines e-invoicing?

It is the requirement to issue invoices as structured, digitally signed data and transmit them to the BIR’s Electronic Invoicing System (EIS) within the allowed window. 

Zoho Books generates and sends invoices to customers, but BIR reporting needs a specific JSON schema, JWS signing and secure API transmission. An integration provides these. 

Do not assume it does. Confirm the current status with Zoho. In most cases a certified connector, middleware or custom development is needed to meet the Philippine schema. 

 Advintek retrieves invoice data from Zoho Books, maps it to the BIR schema, signs and transmits it to EIS, and returns the result and BIR unique ID to your team. 

 The TRAIN Law, the EoPT Act and the CREATE MORE Act, operationalised through Revenue Regulations 11-2025 and 26-2025. 

 Sales invoices, service billings, credit notes and debit notes. Notes must reference the original invoice. 

Phase 1 covers e-commerce and internet businesses, Large Taxpayers Service taxpayers, large taxpayers under the EoPT Act, and users of CAS, CBA or invoicing software. Using Zoho Books for invoicing can bring you into scope. 

 31 December 2026. 

 Micro-taxpayers are currently exempt unless they already use an electronic invoicing system. Small is different from micro, so check your classification. 

 No. They fall under a later phase to be announced through a separate Revenue Regulation. 

Yes. Each branch with its own four-digit branch code must issue e-invoices and be set up separately. 

 No. Covered sellers transmit to the BIR, and the buyer receives the invoice as usual. 

 An invoice is created in Zoho Books, Advintek captures it, converts it to BIR JSON, signs and transmits it to EIS, and the BIR’s response is returned for tracking. 

Through the Zoho Books API and, where useful, webhooks or workflow automation, so new invoices, credit notes and updates are captured without manual entry. 

Often yes. Custom fields for buyer TIN, branch code and BIR document references make mapping reliable. 

 Tax rates and exemptions are matched to BIR categories for 12% VAT, zero-rated and exempt sales so totals reconcile. 

 Use the Philippines edition or your localised organisation setup where available, and confirm tax settings with your accountant before integrating. 

 The BIR schema separates Senior Citizen, PWD, Regular and Special discounts. Generic discounts in Zoho Books may need classification. 

 Four withholding buckets exist in the schema. Record these amounts separately so they can be mapped to the right fields. 

Yes, but each invoice must carry the transaction currency and the PHP equivalent. 

About six to ten weeks, including mapping, the Acknowledgement Certificate, certification, testing and the Permit to Transmit. 

Structured JSON with a JWS digital signature using RS256. 

The BIR’s approval to send live data to EIS after certification and sandbox testing. 

 The BIR’s acknowledgement of your invoicing software, filed at branch level. Without an active one, EIS can reject your payloads. 

 Within three calendar days of the transaction date. 

Up to 1,000 line items per invoice and 100 invoices per API call. 

 Your private key stays in your control, and rotations of the BIR public key must be handled so transmissions do not fail. 

The rejection concerns the data sent to the BIR. Correct and retransmit under the same invoice reference. The customer’s copy is only affected if the content itself was wrong. 

 No. Corrections must be made with credit notes, debit notes or cancel and reissue so the BIR record stays consistent. 

Fines for failure to issue, daily penalties for late or failed transmission, and potentially imprisonment or closure in serious cases. Responsible officers can be personally liable. 

Ten years, in a retrievable digital format, including the complete signed invoice. 

 Only until you go live on EIS. After that, covered transactions must use the e-invoicing process. 

CREATE MORE allows an additional deduction for reporting system costs, subject to eligibility. Confirm with your tax adviser. 

 Contact Advintek to review your Zoho Books setup, confirm scope and plan certification ahead of 31 December 2026.
