POS Billing Software for Retail Stores: A Feature Checklist for Indian Shops

Nestmarketing Team · · 2 min read

A POS system is the one piece of software a retail shop uses every minute it's open. If it's slow at 7 PM on a Saturday, you lose customers at the counter. If its stock numbers are wrong, you lose money quietly every week.

Here's the checklist we work through when building POS systems for supermarkets and retail stores.

Billing at the counter

  • Fast barcode scanning that adds items without a mouse click
  • Search by name or short code for loose items and products without barcodes
  • Weighing scale integration for vegetables, grains and sweets
  • Quick quantity and discount edits from the keyboard
  • Hold and recall bills when a customer goes back for one more item
  • Thermal receipt printing that takes a second, not ten

GST done properly

  • Correct HSN codes and tax rates per product
  • CGST and SGST for local sales, IGST where needed
  • Your GSTIN and the customer's GSTIN on B2B invoices
  • GST summary reports your accountant can use for filing without retyping everything

Payments

  • Cash, card and UPI on the same bill
  • Split payments (part cash, part UPI)
  • Credit sales for regular customers, with outstanding balances tracked
  • End-of-day closing that matches cash in the drawer against the system

Stock

  • Stock reduces automatically with every sale
  • Purchase entries from suppliers that increase stock
  • Low stock alerts with reorder quantities
  • Batch and expiry tracking for packaged food, medicines and cosmetics
  • Stock adjustment for damage, theft and returns, with a reason recorded

Multiple counters and stores

  • Several billing counters on one live stock count
  • Branch-wise stock and stock transfers between stores
  • Head office view of every branch's sales

Customers

  • Phone number lookup at billing
  • Purchase history
  • Loyalty points or simple discounts for regulars
  • Bill sent on WhatsApp instead of, or as well as, paper. Customers like it and it builds your contact list

Reports owners actually open

  • Today's sales by counter and payment type
  • Item-wise sales: bestsellers and slow movers
  • Profit by category
  • Stock value and dead stock
  • Staff-wise billing

Works when the internet doesn't

Billing must continue during an internet outage and sync when the connection returns. This is non-negotiable for most stores outside big city centres.

Off-the-shelf or custom?

Ready-made POS software works well for standard shops. A custom POS makes sense when you have multiple branches, unusual pricing rules, your own loyalty scheme, or need it tied to your CRM, ecommerce store or WhatsApp. Here's how to think about that choice.

We build custom POS and CRM systems for supermarkets, bakeries, restaurants and retail chains. Tell us about your store.
