Software and registered books are different questions
Books of accounts registration with BIR should be considered before adopting a bookkeeping method. Buying an accounting app does not automatically complete the registration or any required system authorization.
Understand the client’s transaction volume, reporting needs and staff capacity. Choose a process the team can maintain accurately.
Three ways to maintain books
Manual books use written entries in registered books. Loose-leaf books use printed records that are permanently bound. Computerized books use the approved or applicable computerized recordkeeping arrangement.
The output, registration and authorization requirements differ. Confirm the procedure for the method and the taxpayer’s current setup, including branches.
ORUS and timing
RMC 3-2023 sets online registration through ORUS and QR-code evidence. Existing taxpayers generally register manual books before use. The circular provides annual deadlines of 15 days after year-end for bound loose-leaf books and 30 days for computerized books, subject to applicable rules and approved extensions.
RMC 4-2026 reiterated mandatory ORUS registration for loose-leaf and computerized books and specified exceptional manual procedures for system issues. Check current advisories; do not assume an old temporary extension is permanent.
Build a recordkeeping handover
Keep the registration evidence, book details and responsible person. Explain how entries are reviewed, corrections made and supporting documents retained. Confirm that the year-end output can be produced.
