Why Word, Excel, Google Docs, and Google Sheets Do Not Qualify as BIR E-Invoices

Executive Summary

Many businesses prepare invoices using Microsoft Word, Microsoft Excel, Google Docs, or Google Sheets and then save or send them electronically.

Under BIR Revenue Memorandum Circular No. 98-2026, however, invoices manually created using these office productivity applications are not considered valid electronic invoices for tax compliance purposes.

This does not mean that these programs cannot be used for internal recordkeeping or document preparation. The issue is that a BIR-compliant electronic invoice must satisfy additional requirements.

It must be generated through a duly registered, approved, or accredited accounting or invoicing system, use structured electronic data, be capable of electronic issuance to the buyer, and contain data that can be electronically extracted and processed for BIR reporting.

For covered taxpayers preparing for the December 31, 2026 e-invoicing deadline, relying only on Word, Excel, Google Docs, or Google Sheets is therefore not enough.

Why These Applications Do Not Qualify as E-Invoicing Systems

Word, Excel, Google Docs, and Google Sheets are primarily productivity tools.

They allow users to type, calculate, format, and save information, but simply creating an invoice in one of these applications does not satisfy the BIR definition of an electronic invoice.

RMC No. 98-2026 expressly states that invoices manually created using office productivity applications, including Microsoft Word, Microsoft Excel, Google Docs, Google Sheets, and similar programs, are not valid electronic invoices for tax compliance purposes.

The important distinction is between a digital document and an electronic invoice.

A digital document may simply be something created or stored electronically.

A BIR electronic invoice must come from a compliant invoicing system and contain structured data that can be processed electronically.

What Makes a BIR-Compliant Electronic Invoice?

Under RMC No. 98-2026, an electronic invoice must satisfy several requirements.

It must be generated through a duly registered, approved, or accredited accounting or invoicing software or system.

It must use a structured electronic format, meaning the underlying information is organized in a way that computers can automatically read and process.

The invoice must also be capable of being electronically issued to the buyer through channels such as email, online viewing, QR code, mobile application, or web-based platform.

Finally, the invoice data must be capable of electronic extraction, processing, and transmission for BIR electronic sales reporting purposes.

This is why manually typing an invoice in Excel and sending the resulting file by email is not enough.

Step-by-Step Guide: Check Your Current Invoice Process

Step 1: Identify How Your Invoice Is Created

Start with the actual process used by your business.

If employees manually enter the invoice information into Word, Excel, Google Docs, or Google Sheets, the resulting document is not considered a valid electronic invoice under RMC No. 98-2026.

Saving that document as a PDF does not change this.

Step 2: Check Whether You Are Using an Accounting or Invoicing System

A compliant electronic invoice must originate from the appropriate accounting or invoicing software.

This could include a computerized accounting system, ERP, POS, dedicated invoicing platform, or other compliant software.

The important question is not simply whether the invoice was made on a computer.

It is whether it was generated by a system capable of meeting the BIR's electronic invoicing requirements.

Step 3: Check Whether the Data Is Structured

Structured data allows computers to identify and process information such as the invoice number, buyer details, transaction date, taxable amount, VAT, discounts, and total sales automatically.

A manually formatted spreadsheet may look organized to a person, but that does not automatically mean it satisfies the BIR's structured-data requirements.

The BIR's existing electronic reporting framework uses JSON for transmitting sales data, although businesses may use other structured formats internally if the required information can ultimately be converted into the BIR-prescribed format.

Step 4: Confirm That the Invoice Can Be Issued Electronically

A compliant system should be capable of sending or making the electronic invoice available to the buyer electronically.

Examples include email transmission, online customer portals, QR-code retrieval, mobile applications, and web-based platforms.

Simply printing an invoice generated from a computerized system does not make it an electronic invoice if the system cannot electronically issue the invoice and support the required data transmission.

Step 5: Review Whether Your System Needs to Be Upgraded

Businesses that currently rely on Word, Excel, Google Docs, or Google Sheets for invoicing should review whether they need to migrate to or implement proper invoicing software.

Covered taxpayers should also consider the BIR authorization and system requirements that apply before electronic invoices are issued.

Do not wait until the deadline to begin evaluating your current process.

Why Saving the Invoice as PDF Does Not Fix the Problem

A common assumption is that converting an Excel or Word invoice into PDF turns it into an electronic invoice.

It does not.

The BIR looks at the system and data behind the invoice, not merely the final file format.

If the original invoice was manually created using an office productivity application, turning it into a PDF and emailing it does not make it a compliant electronic invoice.

The PDF may still be useful for viewing or sharing, but the underlying invoicing process must independently meet the BIR requirements.

Risks and Penalties

Businesses that assume their current Word or Excel invoicing process is already compliant may discover gaps when the mandatory e-invoicing rules apply to them.

This can lead to rushed software changes, implementation problems, incomplete data, or inconsistencies between invoices and accounting records.

For covered taxpayers, failure to comply with the applicable electronic invoicing requirements may also result in penalties under relevant BIR rules.

There is also a practical audit risk.

If the business cannot properly extract or reconcile invoice information with its accounting records and future electronic sales reporting requirements, compliance reviews may become more difficult.

Practical Examples

Example 1: Excel Invoice Emailed to a Customer

ABC Consulting prepares every invoice using Microsoft Excel.

The employee enters the customer name, services, VAT, and total manually, saves the file as PDF, and sends it by email.

Although the invoice is transmitted electronically, it is not a valid BIR electronic invoice simply because it was emailed.

The invoice was manually created in Excel, which RMC No. 98-2026 expressly identifies as an office productivity application that does not qualify for electronic invoicing purposes.

Example 2: Google Sheets Invoice

XYZ Trading uses a Google Sheets template containing formulas that calculate VAT automatically.

Employees enter customer information and print or email the completed sheet.

The presence of formulas does not automatically make the spreadsheet a compliant electronic invoicing system.

The business would still need a system meeting the BIR's structured-data, electronic issuance, and data-processing requirements.

Example 3: Accounting System That Generates a PDF

A business uses dedicated accounting software that automatically creates invoice data and generates a PDF copy for the customer.

If the underlying system is properly registered or approved, creates structured invoice data, supports electronic issuance, and allows the required information to be electronically extracted and processed, the resulting invoice may qualify as an electronic invoice.

The PDF itself is not what makes it compliant the system behind it does.

Frequently Asked Questions

Can I use Excel to create a BIR electronic invoice?

Not by manually creating the invoice in Excel.

RMC No. 98-2026 specifically states that invoices manually created using Microsoft Excel and similar applications are not considered valid electronic invoices.

What about Google Sheets with automated formulas?

Automated calculations do not by themselves turn Google Sheets into a compliant electronic invoicing system.

The BIR specifically includes Google Sheets among the office productivity applications that do not qualify when invoices are manually created through them.

Can I create an invoice in Word and email it?

You may use Word to prepare a document, but a manually created Word invoice does not qualify as a compliant electronic invoice under RMC No. 98-2026.

Does converting the document to PDF make it compliant?

No.

A manually prepared invoice does not become a compliant electronic invoice simply because it is converted into PDF or transmitted electronically.

Do I need expensive software?

Not necessarily.

The important issue is whether the invoicing solution meets the applicable BIR system, structured-data, electronic issuance, and authorization requirements.

Businesses should assess their size, transaction volume, accounting setup, and compliance needs before choosing a solution.

What should covered businesses do before December 31, 2026?

They should review their current invoicing process, identify whether they are covered by the mandatory e-invoicing rules, evaluate their accounting or invoicing software, and address system and BIR authorization requirements before the deadline.

Review Your Invoicing Process Before the Deadline

Word, Excel, Google Docs, and Google Sheets may be convenient tools for preparing business documents, but convenience does not automatically equal BIR e-invoicing compliance.

RMC No. 98-2026 makes the distinction clear: a compliant electronic invoice must come from the appropriate invoicing system, use structured electronic data, support electronic issuance, and allow invoice information to be electronically processed.

If your business is still creating invoices manually through office productivity applications, now is a good time to review whether your current setup needs to change.
