MISAC eBilling Lite User Guide

Nepal IRD CBMS e-invoicing Multi-tenant SaaS v1.0.0

Everything you need to run day-to-day billing in MISAC eBilling Lite - raising tax invoices, issuing credit and debit notes, recording receipts and purchases, maintaining your masters, and keeping every document in sync with the Inland Revenue Department (IRD) CBMS portal. Each guide walks through the screen field by field.

New here? Start with the basics

If this is your first time, read Getting Started first. It covers logging in, the dashboard, how dates work (Bikram Sambat vs English), what gets sent to the IRD, and the document locks that protect issued bills. The rest of the guide assumes you know those concepts.

At a glance

A few ideas appear in almost every screen. Skim these now; each guide links back here.

ConceptWhat it means for you
Bikram Sambat (BS) dates Nepal's official calendar. Issue and transaction dates are shown in BS, but every calculation uses the English (AD) equivalent behind the scenes. The system stamps today's BS date on issue - you cannot back-date a tax invoice.
IRD / CBMS The Central Billing Monitoring System. Each tax invoice and credit note is reported to the IRD automatically. The IRD / CBMS screen shows the sync status of every document. (Debit notes are internal purchase returns and are not sent.)
Document locks (immutability) Once issued, an invoice or credit note can never be edited or deleted - the database itself blocks it. To correct a mistake you void the invoice (which issues a credit note) rather than changing it.
Fiscal year Documents are numbered within a Nepali fiscal year (for example 2081/82). Numbering restarts each year and the year is printed on every bill.
Demo mode A new or trial company starts in demo mode so you can practise safely. Demo documents are not sent to the IRD and can be cleared. Going live freezes that.
Roles What you can see and do depends on your role (admin, biller, viewer…). If a menu or button is missing, your role may not grant it - ask your company admin.
Why some things cannot be changed

eBilling Lite is certified against IRD rules. Fields and actions that affect a filed tax position - issued amounts, document numbers, the company PAN, the print layout - are deliberately locked after approval. Where you see a lock note in this guide, it is a compliance rule, not a bug. MISAC Intelligence Pvt. Ltd can lift a lock with an approved request from IRD. In no case locks can be lifted without approval from IRD.
