This guide is for owners of kirana, garment, electronics and similar shops in Nadiad, Anand, Vadodara and across Gujarat who are choosing billing software for the first time, or replacing one that no longer fits. It starts with what the software must do at the counter, then covers internet, hardware, your data and the questions to ask before you pay.
What features must a POS system have for a retail shop?
A POS (point of sale) system is the software at your counter that makes the bill. For a shop, these seven things matter most.
- GST-ready invoices. The invoice should carry your shop details and GSTIN, show the tax split and number bills in a clear sequence. Whether you also need HSN codes, e-invoicing or e-way bills depends on your business, so confirm current GST requirements with your CA before you choose.
- Stock that drops when you sell. Every bill should reduce stock by itself, so the number on screen matches the shelf without a weekly count.
- Credit customers (udhaar). Each regular customer needs a ledger: what they bought, what they paid and what is still due. You should be able to take part payments and see everyone who owes you on one screen.
- Returns and exchanges. A return should put the item back in stock and adjust the customer’s balance or refund, with a record of who approved it.
- A day-end summary. At closing you should see sales by cash, UPI, card and credit, plus returns and discounts, so you can match the drawer in minutes.
- Staff roles. The owner sees everything. Counter staff can bill, but cannot change prices, delete bills or see profit unless you allow it.
- Speed at the counter. Search by name or code, scan a barcode, repeat a recent bill. A slow screen costs you patience in the queue.
Other features, such as loyalty points, an online store link or several branches, can wait until the basics work. Also ask whether the software can send a bill as a PDF on WhatsApp, because some customers prefer it to a printed slip.
Test with a real day. Ask for a trial and enter one real day of bills, including a return and a credit sale. Software that looks good in a demo can feel slow with your full item list.
Should a shop choose cloud or offline billing software?
Cloud software runs over the internet. Offline software runs on a computer in your shop. Neither is always better. The useful question is what happens at 7 pm on a busy day when your internet drops.
| What you care about | Offline (on one computer) | Cloud only | Works offline, syncs later |
|---|---|---|---|
| Billing when internet drops | Keeps working | Stops | Keeps working |
| Checking sales from home | Usually not possible | Possible | Possible after it syncs |
| Backups | Your job, so set a routine | Handled by the provider; ask how | Handled by the provider; ask how |
| If the computer breaks | Data is at risk without a backup | Log in from another device | Log in from another device |
| More than one counter or branch | Harder to combine | Natural fit | Natural fit |
Ask any vendor exactly which parts work without internet: billing, printing, stock lookup and credit balances are not always the same. If your connection is unreliable, the third column is worth the extra conversation.
What hardware does a billing counter need?
Decide the software first, then buy hardware it supports. A typical counter has:
- a computer, tablet or phone to bill on
- a barcode scanner (many scanners behave like a keyboard, but confirm the model with your vendor)
- a receipt printer, and the paper size it takes
- a cash drawer, if you handle a lot of cash
- a label printer, if you print your own price tags
- power backup for the billing computer and the router
Ask which of your existing devices can be reused before you buy anything new.
Who owns your data, and can you take it with you?
Your item list, customer ledger and bills are the record of your business. Ask for three things in writing before you start:
- Export. You can download items, customers, bills and credit balances in Excel or CSV at any time, not only when you leave.
- Backup. You know how often data is backed up, where it is kept and who restores it. Ask to see a restore.
- Admin access. The main account is in your name, not in a staff member’s or the vendor’s.
Your CA will probably ask for sales and purchase data at filing time, so check that the export suits what they need.
Also ask what happens to your data if you stop using the software, or if the vendor stops offering it. A clear answer now is easier than a hard conversation later.
Is custom software better than an off-the-shelf billing app?
Not automatically. Many shops are well served by a standard billing app, and starting with one is a sound choice.
An off-the-shelf app usually fits when:
- your billing is standard: items, quantity, tax, payment
- you want to start this week
- you have one counter and a few staff
Custom software is worth discussing when:
- your credit rules, price lists or WhatsApp orders do not fit a standard app
- billing must connect to other systems, such as stock, a website or Tally exports
- you have outgrown the app but keep paying for features you do not use
If you are weighing custom work, read what decides the cost and timeline of custom business software first. If you also sell to dealers or wholesale customers, our guide on billing, stock and dispatch for distributors covers that side.
What should you ask before you buy? A buyer’s checklist
- Can I try it with my own item list and one real day of bills?
- Can you show a credit customer’s ledger and the list of who owes me?
- What happens to billing when the internet is down?
- Which printers and scanners work with it?
- Can I export all my data to Excel today?
- How are backups done, and who restores them?
- Can I set what each staff member sees and changes?
- Who updates GST settings when rules change, and what does my CA need from the reports?
- Who do I call when it stops, and how quickly will I get a reply?
- What does the first month look like: setup, training and checks?
