What a VAT invoice in Nepal must contain (and when e-billing becomes mandatory)
Rule 17 fields, Bikram Sambat numbering, the IRD e-billing and CBMS thresholds, and how to get all of it from your billing system instead of a template.
Draft — thresholds and wording to be confirmed with your accountant before relying on them.

A tax invoice in Nepal is a regulated document. Getting it right is not hard, but getting it right every time, in sequence, for the right fiscal year is a systems problem.
The fields
Guides to VAT Rule 17 list the essentials: the heading “Tax Invoice” (कर बीजक); your name, address and PAN exactly as registered; a sequential, fiscal-year-based invoice number that never skips; the date in AD and BS; the customer's name, address and PAN where they are registered or the amount is NPR 10,000 or more; line descriptions with quantity, unit and rate; discounts as a separate line; and the VAT amount shown separately from the total.
Numbering and the fiscal year
Nepal's fiscal year runs Shrawan to Ashadh. Invoice numbering restarts each fiscal year and must be gapless. Reprints must be labelled as copies. A spreadsheet can do this until the day two people issue invoices at once.
E-billing and CBMS
The IRD's Electronic Billing Procedure requires businesses above a turnover threshold to issue bills through IRD-listed software, and larger ones to connect that software to the Central Billing Monitoring System. Current guidance cites NPR 10 crore for e-billing approval (lower for hotels and restaurants) and real-time CBMS sync above NPR 25 crore, with the FY 2083/84 budget announcing CBMS linkage for e-billers above NPR 10 crore. Cloud systems must keep the central server in Nepal with IRD access. Treat these numbers as a moving target and confirm them with your accountant.
What Tola Pay prints
Every invoice is in NPR with the 13% VAT split, your legal name, PAN and bank details, sequential numbering per workspace and a PDF your accountant can file. Tax-inclusive or exclusive is a per-plan setting. CBMS integration is on our roadmap for workspaces that cross the threshold.
