Is any accounting software BIR-accredited? What the BIR requires, and where Odoo fits

Most BIR questions we hear before an Odoo project start the same way: "Is Odoo BIR-approved?" The honest answer is that the BIR does not approve software brands the way people expect. It sets rules in Revenue Regulations (RR), explains them in Revenue Memorandum Circulars (RMC), and tells its own offices how to apply them in Revenue Memorandum Orders (RMO). Your system has to meet those rules, and your business registers it. This guide lists the issuances that matter for a company running its books in an ERP, and where Odoo fits.

Has the BIR said anything about Odoo?

No. We found no BIR issuance, advisory or published list that names Odoo or any Odoo partner. That includes registered CAS lists and anything about e-invoicing providers.

• No accredited e-invoicing providers yet. In a public advisory dated 14 September 2026, the BIR said it has not accredited, authorised, certified, recognised or endorsed any entity as an e-invoicing service provider, and warned against claims such as "BIR-accredited" or "BIR-certified".
• Accreditation rules now exist. RMC 110-2026 (12 October 2026) sets out the requirements for e-invoicing service providers to be accredited. No list of accredited providers had been published when we wrote this.
• The permit is yours. Under RMC 98-2026 the BIR issues the PTI to the taxpayer, specifying the approved software or system. If you change or migrate systems, you need a new or amended PTI.

So treat any "BIR-accredited ERP" claim with care. What you can say accurately is: your business registers Odoo as its computerised books and uses it to apply for a PTI.

TechNext is an Odoo Ready Partner. We are not affiliated with, accredited by or acting for the BIR or any government agency, and we do not file or register on your behalf.

The issuances that matter

Older CAS rules (RMO 29-2002, RR 9-2009 and RMC 5-2021) still shape how computerised systems are registered, but the procedure has changed several times. Check the current process with your revenue district office before you apply.

E-invoicing: who is covered by 31 December 2026

• E-commerce and internet sellers that are small, medium or large. Micro taxpayers are exempt.
• Taxpayers under the Large Taxpayers Service, and large taxpayers under RA 11976 and RR 8-2024.
• Businesses on a CAS or CBA with electronic invoicing or other invoicing software.
• Exporters, incentive-registered enterprises and POS users join later, through a separate regulation.

RMC 98-2026 is explicit that invoices made in Word, Excel or Google Sheets are not e-invoices, and that a system that only prints invoices is not e-invoicing. For the full checklist, read our BIR e-invoicing guide.

Where Odoo fits

Odoo's Philippine localisation produces the data for the recurring BIR reports from the entries you already post:

• Withholding taxes with their ATC codes, and the 2307 per payee
• SAWT and QAP as DAT files for the BIR's tools
• SLSP as a DAT file, and the 2550Q VAT summary
• Your TIN, branch code and RDO on the company record

Odoo's documentation does not cover the BIR's EIS: Odoo has no built-in connection to it, and TechNext has not built one. If you are covered, we assess the options with you and quote any connection separately. See what the reports look like in our sample BIR reports (fictitious data).

What to do next

1. Confirm your classification and group with your accountant: covered now, later, or exempt.
2. Register or update your books in ORUS, and keep the acknowledgement on file.
3. Set up withholding and VAT in Odoo so the 2307, SAWT, QAP, SLSP and 2550Q come from your entries, not from spreadsheets.
4. Prepare the PTI application with process flows and sample invoices from the system you will actually use.
5. Plan the EIS connection and the EIS Certification that follows within six months.

You don't need to hire your own team. A TechNext adviser maps your BIR reports and invoice flows first, then our team in Taguig City sets Odoo up for them and supports it after go-live. You file and register with the BIR yourself. See how we set up Odoo for BIR requirements.
