OneFlow – Nepal’s IRD Approved E‑Billing & Accounting Software for 2025 - Best Accounting Software In Nepal

IRD Directives & Procedures: The Legal Backbone

The Inland Revenue Department (IRD) has set strict rules for electronic billing through:

Public Notice (Jestha 20, 2079 / June 2022)
- Mandatory e‑billing for:
  - VAT‑registered businesses with annual turnover above NPR 10 crore.
  - Hospitality/restaurant/canteen sectors above NPR 5 crore.
  - Certain sectors like department stores and flooring businesses above NPR 10 crore.
Public Notice Updates
- The NPR 250 million (Rs 25 crore) CBMS sync threshold was already in place; the 2023 notice was a compliance reinforcement urging businesses to complete migration.
Electronic Billing Procedure, 2074 (4th Amendment, Oct 2021)
- Defines technical and procedural requirements for e‑billing software, including CBMS integration, invoice formatting (Annex‑5/6), hosting conditions, and audit‑trail standards.
Directives
- Reinforces the above rules, detailing submission process for software listing, technical compliance checks, and enforcement guidelines for tax offices.

👉 These rules make it clear: if you meet the turnover thresholds or are in a listed sector, you must use IRD‑approved billing software—and OneFlow is fully compliant.

Under the Electronic Billing Procedure, 2074 (4th amendment) and directive 1958456687, any IRD‑certified software must:

Support CBMS integration for real‑time or scheduled data sync.
Generate fiscal‑year based invoice numbers with proper reprint labeling (Copy of Original–2/3…).
Maintain an immutable audit trail—no hard deletes; every edit must record user, time, and reason.
Store data securely—cloud hosting must be in Nepal (or with local backup accessible to IRD).
Enable VAT rebate reporting (Schedule‑8 format) for digital payments like QR and card.

OneFlow meets all these standards—from Annex‑5 invoice formats to CBMS API communication and secure local hosting.
