Real-time stock sync
This is the whole point. Stock should update in seconds on every channel. If you have more than one branch, make sure you can see stock by location and move items between branches.
Fast barcode billing
The counter must stay quick when the shop is busy. Look for barcode scanning, hold and resume bills, discounts, returns, and support for the receipt printer you already use.
13% VAT billing
If your business is VAT registered, your system should work out 13% VAT correctly and print invoices with the details the Inland Revenue Department (IRD) expects, such as your PAN, the invoice number and the VAT amount. It should also keep a clean sales record for your VAT returns. Rules and formats can change, so check the latest IRD requirements or ask your accountant before you choose software.
Local payments
Your customers pay with eSewa, Khalti, bank QR and cash on delivery. Make sure the system handles the ones your customers actually use, online and at the counter.
Delivery management
You should be able to send orders to your courier, follow their status and keep track of cash on delivery money.
Reports and staff permissions
Look for daily sales, best sellers, low-stock alerts and profit by product. Staff roles help too, so only the right people can change prices or give discounts.
Cloud access
With a cloud system you can check sales from your phone, add a branch without buying a new server, and avoid losing data if a computer breaks. Ask what happens during a short internet cut.
