What a POS system does
POS stands for point of sale: the place where a customer pays. A POS system is the software and hardware at that counter. It finds the item, prices it, applies any discount, prints a GST bill, takes the payment and records the sale.
A good POS also does the work behind the counter: it reduces stock as items are sold, keeps a record of every cashier’s shift, and closes the day with a figure that the cash in the drawer can be checked against.
Retail POS and restaurant POS
| Retail POS | Restaurant POS | |
|---|---|---|
| The sale | Scan or search items, bill, pay | Take an order for a table, add to it, bill at the end |
| Kitchen | Not needed | Kitchen order tickets (KOT) or a kitchen display |
| Stock | Reduces the item sold | Reduces the ingredients, through a recipe |
| Typical extras | Barcodes, loyalty, offers | Tables, modifiers, happy hours, split bills |
The hardware
- A terminal a PC, a touchscreen or a tablet.
- A thermal receipt printer, and in restaurants usually a second one or a screen in the kitchen.
- A barcode scanner for retail.
- A cash drawer, and a card machine or UPI QR for digital payments.
What Indian businesses need from it
- A proper GST bill, with the tax worked out per item and the right HSN codes.
- Payment split by mode, because one bill is often paid partly in cash and partly by UPI or card.
- Credit customers on account, the familiar khata, with a running balance.
- Cashier shifts with an opening float and a counted close, so shortages are found the same day.
- Offers, coupons and loyalty applied by rule, so a discount is never a cashier’s private decision.
Why the POS should not stand alone
A standalone POS knows what was sold but not what is left in the godown, and its day-end figures have to be typed into the accounts. That is where stock mismatches and missing cash hide.
When the POS is part of the same system as inventory and accounts, each bill reduces stock and posts the sale, tax and payment to the ledger directly. The day close then becomes a check rather than a reconstruction.
Cloud POS and connectivity
Many modern POS systems run in the cloud, which lets an owner see every outlet live and keeps prices the same everywhere. The trade-off is that the counter needs internet. If a product cannot bill offline, plan a backup connection, such as a mobile hotspot, for outlets with an unreliable line.
In short
- A POS system is the software and hardware at the counter: it bills, takes payment and records the sale.
- Restaurants add kitchen tickets, tables and recipes; retail adds barcodes, loyalty and offers.
- Indian counters need GST bills, split payment modes, khata and a counted day close.
- A POS connected to stock and accounts avoids re-typing and hidden mismatches.
