Off-the-shelf billing software works, until it doesn’t
Most businesses in Butwal, Bhairahawa and across Nepal start with an off-the-shelf billing or accounting package. As they add branches, warehouses, staff and product lines, they end up running the business on a mix of billing software, Excel sheets and WhatsApp messages.
This guide explains when a custom ERP, POS or accounting system makes sense, what Nepal’s IRD e-billing rules mean for your software, and how to plan the project.
What is an ERP, and how is it different from billing software?
Billing or POS software records sales and prints invoices. An ERP (Enterprise Resource Planning) system connects every part of the business in one place: purchase, sales, inventory, production, HR, payroll and accounting. When a sale is billed at the counter, stock is reduced, the ledger is updated, and the owner sees it on a dashboard, all without re-entering data.
Signs your business needs a custom system
- You re-enter the same data in billing software and Excel every day.
- Stock figures never match what is physically in the godown.
- You run more than one branch or warehouse and cannot see them together.
- Your workflow (credit limits, schemes, batch/expiry, production, commissions) does not fit the software you bought.
- Month-end closing takes days because reports must be built by hand.
Custom vs off-the-shelf: an honest comparison
Off-the-shelf software is cheaper to start and quick to set up. It is the right choice for a single shop with a standard workflow.
Custom software costs more upfront but is built around how you actually work, integrates with your other tools, and grows with you. It usually pays off for distributors, manufacturers, multi-branch retailers, hospitals, schools and any business with unusual processes.
A common middle path is to start with one custom module, such as billing with inventory, and add accounting, HR and reporting in later phases.
IRD e-billing and CBMS: what to know
Nepal’s Inland Revenue Department (IRD) regulates computerised billing. Businesses that issue bills from software are expected to use billing software listed with the IRD, and businesses above the turnover threshold must connect their billing to the IRD’s Central Billing Monitoring System (CBMS). The threshold has changed over the years and differs for sectors such as hotels and restaurants, so always confirm the current rule with your tax office or auditor.
For a custom system this means planning for VAT/PAN details, continuous non-reusable invoice numbers, Bikram Sambat dates, proper cancellation (credit notes instead of deleting bills), audit logs, and CBMS integration where required.
What modules should a Nepali business ERP include?
- Sales & POS: counter billing, barcode, receipt printing, discounts, offline mode.
- Inventory: multi-warehouse stock, batch and expiry, reorder alerts, stock valuation.
- Purchase: purchase orders, supplier ledger, landed cost for imports.
- Accounting: ledgers, VAT reports, receivables/payables, bank reconciliation, financial statements.
- HR & Payroll: attendance, salary, SSF and tax deductions.
- Reports & dashboards: daily sales, branch comparison, profit by product.
How much does custom ERP or POS software cost in Nepal?
Cost depends on the number of modules, users, branches and integrations. A focused billing and inventory system is a much smaller project than a full multi-branch ERP. The best way to control cost is to define the first phase tightly and add modules once the core is in daily use.
