Introduction
Walk into a POS software demo and everything looks impressive. Clean screens, fast billing, colourful dashboards. Every vendor says the same things: “GST ready”, “easy to use”, “complete inventory”, “24/7 support”.
Then you buy it, and the problems begin. The barcode scanner does not work with the software. Billing freezes when the internet drops. Returns are confusing. Your cashier makes mistakes on discounts. The vendor takes three days to answer a support query.
The gap between a good demo and a good daily experience is where most POS buying mistakes happen.
This guide closes that gap. Instead of a long list of everything a POS can do, it focuses on 10 features that decide whether a POS works for an Indian shop. For each one, you will see:
- Why it matters
- What to look for
- How to test it in a demo
- Red flags to watch for
At the end, you will find a scorecard to compare vendors side by side, a short implementation plan, and FAQs.

Before You Compare Features: Know Your Own Needs
A feature is only valuable if your shop needs it. Spend ten minutes answering these questions first:
- What do you sell, and how many items (SKUs) do you have?
- How many bills do you create on a busy day?
- How many counters and cashiers do you have?
- Do you sell on credit?
- Do you have size, colour, batch, or expiry requirements?
- Do you plan a second shop or online sales in the next two years?
- How reliable is your internet connection?
- What is your total budget, including hardware, setup, and support?
Keep these answers beside you while you evaluate each feature below.
Feature 1: GST-Compliant Billing
Why it matters
Every registered Indian retailer must issue correct tax invoices. Errors in tax rates, HSN codes, or invoice formats create problems at filing time and can attract notices.
What to look for
- Tax invoice, bill of supply, and composition scheme formats
- CGST, SGST, IGST, and cess handling
- Item-wise HSN or SAC codes and tax rates
- Easy bulk update when GST rates change
- Inclusive and exclusive tax pricing
- GSTR-1 and GSTR-3B ready reports
- Credit notes and debit notes for returns
- E-invoice and e-way bill support (or a clear upgrade path)
On e-invoicing specifically, it applies to GST-registered businesses whose aggregate annual turnover crossed ₹5 crore in any financial year since 2017-18, a threshold in force since August 2023 and unchanged as of June 2026. Most small shops are below this, but if you are growing, pick software that can add it later without a switch. accountune
How to test it in a demo
- Create a bill with items at different tax rates and check the tax split
- Create an inter-state sale and confirm IGST is applied
- Process a return and generate a credit note
- Export a GST summary report and ask your accountant to review it
Red flags
- Tax rates are hard-coded and need a developer to change
- No HSN-wise summary report
- The vendor cannot explain how they handled past GST changes
Feature 2: Offline Mode That Actually Works
Why it matters
Internet cuts happen, especially in smaller towns and busy markets. If billing stops, you lose sales and customers walk away.
What to look for
- Full billing without internet, including discounts and returns
- Local storage of items, prices, and customer data
- Automatic syncing when the connection returns
- Clear indication of sync status
- Conflict handling if two devices change the same data
How to test it in a demo
- Disconnect the internet and create several bills
- Process a return while offline
- Reconnect and check that every bill appears in reports and stock updates correctly
Red flags
- “Offline mode” only lets you view data, not bill
- The vendor cannot explain how sync conflicts are resolved
- Bills created offline do not reduce stock after syncing
Feature 3: Fast Billing with Barcode Support
Why it matters
Speed at the counter directly affects customer experience and queue length. Typing item names for every sale is slow and error-prone.
What to look for
- Barcode scanning with common USB and Bluetooth scanners
- Built-in barcode generation and label printing
- Quick search by name, code, or partial text
- Keyboard shortcuts for frequent actions
- Hold and recall bills
- Weight-based billing with scale integration for loose items
- Touchscreen-friendly layout if you use a tablet or touch terminal
How to test it in a demo
- Scan 20 items in a row and time the process
- Print a barcode label for a new item and scan it
- Hold a bill, serve another customer, and recall the first bill
Red flags
- Scanner needs special settings or drivers that the vendor cannot support
- Searching for items is slow with a few thousand products
- Label printing needs a separate tool
Feature 4: Real-Time Inventory Management
Why it matters
A POS that bills but does not manage stock leaves you guessing. Accurate inventory prevents lost sales from stockouts and cash tied up in slow items.
What to look for
- Automatic stock reduction on every sale and increase on purchase or return
- Low-stock alerts and reorder levels
- Purchase entry and supplier records
- Variants for size, colour, and style (clothing, footwear)
- Batch and expiry tracking (pharmacy, food, cosmetics)
- IMEI or serial number tracking (mobile and electronics)
- Stock transfers between shops or godowns
- Physical stock audit and adjustment tools
- Stock valuation reports
How to test it in a demo
- Sell an item and check that stock reduces immediately
- Receive a purchase and confirm stock increases
- Run a stock audit with a deliberate mismatch and check how adjustments are recorded
Red flags
- Variants are handled as separate unrelated items
- No audit trail for stock adjustments
- Negative stock is allowed without any warning or permission control

Feature 5: Multiple Payment Modes and Smooth Reconciliation
Why it matters
Indian customers pay by cash, UPI, cards, wallets, and sometimes credit. Mismatched payment records are a common source of daily cash differences.
What to look for
- Cash, UPI, card, wallet, and cheque support
- Split payments (part cash, part UPI)
- Dynamic UPI QR with the bill amount
- Integration with card machines and payment apps where available
- Daily cash register opening and closing
- Payment-mode-wise sales reports
- Customer credit (udhaar) with ledger and due reminders
How to test it in a demo
- Create a bill paid partly in cash and partly by UPI
- Close the day and check whether the cash report matches
- Create a credit sale and record a later payment
Red flags
- No day-end closing or cash reconciliation
- Credit sales are not linked to customer ledgers
- UPI payments must be marked manually, with no verification support
Feature 6: Returns, Exchanges, Discounts, and Offers
Why it matters
Real retail is not only straight sales. Returns, exchanges, festival discounts, and combo offers are daily realities, and mishandling them causes stock and accounting errors.
What to look for
- Returns against the original bill or without it, with controlled permissions
- Exchange handling with price difference
- Item-wise and bill-wise discounts, with limits per role
- Coupons, buy-one-get-one, combos, and time-based offers
- Loyalty points and customer-specific pricing
- Discount approval for high percentages
How to test it in a demo
- Return one item from a multi-item bill
- Exchange an item for a higher-priced one
- Apply a combo offer and a manual discount together
Red flags
- Returns do not update stock or tax records properly
- Any cashier can give any discount
- Offers need manual calculation
Feature 7: User Roles, Permissions, and Audit Trail
Why it matters
Billing counters are where leakage happens, through unrecorded sales, unauthorised discounts, deleted bills, or cash mismatches. Control features protect you.
What to look for
- Separate logins for owner, manager, and cashier
- Permission settings for editing prices, deleting bills, giving discounts, and viewing profit
- Activity logs showing who did what and when
- Alerts for suspicious actions such as repeated cancellations
- Cashier-wise sales and collection reports
- Shift opening and closing
How to test it in a demo
- Log in as a cashier and try restricted actions
- Delete or edit a bill as a manager, then check the log
- Generate a cashier-wise report
Red flags
- One shared login for everyone
- Bills can be deleted without any trace
- No way to restrict access to profit and cost data
Feature 8: Customer Management, Digital Receipts, and Marketing Tools
Why it matters
Repeat customers are the cheapest source of sales. A POS that captures customer details lets you build loyalty without a separate tool.
What to look for
- Customer database with purchase history
- Loyalty points or membership tiers
- Birthday and anniversary reminders
- WhatsApp, SMS, or email receipts
- Bulk messaging for offers (with consent and platform rules followed)
- Feedback collection
- Credit limits and outstanding balances
How to test it in a demo
- Add a customer during billing in under 10 seconds
- Send an invoice by WhatsApp or SMS
- Check how loyalty points are earned and redeemed
Red flags
- Customer data cannot be exported
- Messaging requires a third-party subscription with unclear costs
- No way to see what a customer bought last time
Feature 9: Reports, Dashboards, and Multi-Store Control
Why it matters
Data is only useful when it is easy to read. Owners need to know what sells, what makes profit, and what to reorder, without being at the counter all day.
What to look for
- Daily, weekly, and monthly sales reports
- Item-wise, category-wise, and brand-wise sales
- Profit and margin reports
- Fast-moving and dead stock reports
- Peak hour analysis
- Purchase and supplier reports
- Tax summary reports
- Mobile dashboard for owners
- Central view across multiple stores, with store-wise comparison
- Export to Excel or PDF
How to test it in a demo
- Ask the vendor to show a profit report for a sample month
- Check whether you can filter by date, item, cashier, or store
- View the dashboard on a phone
Red flags
- Reports are limited to total sales only
- Profit cannot be calculated because purchase cost is not tracked
- Multi-store reporting is “coming soon”
Feature 10: Hardware Compatibility, Security, Support, and Pricing Transparency
This final feature is really a bundle of practical factors that decide how smooth daily life will be.
10a. Hardware compatibility
Confirm support for your thermal printer, barcode scanner, label printer, cash drawer, weighing scale, customer display, and any card machine. Ask for a list of tested models. Mismatched hardware is a common source of frustration.
10b. Data security and backups
- Encrypted data and secure logins
- Automatic cloud backup and easy restore
- Clear data ownership (your data stays yours)
- Easy export of all your data in Excel or CSV format
10c. Support quality
- Support channels (phone, chat, remote screen sharing)
- Support hours and language
- Response time commitments
- Onboarding help and training materials
- Active product updates
10d. Pricing transparency
Ask for a written quote covering:
- Software fee (subscription or licence)
- Setup and data import
- Training
- Hardware (if bundled)
- Charges for additional users, counters, or stores
- Message credits (SMS, WhatsApp)
- Annual maintenance and renewal rates
How to test it
- Contact support before you buy, with a technical question, and note how fast and clearly they respond
- Ask a current customer in your trade about their experience
- Request a trial or pilot period
Red flags
- Vague answers about backups or data export
- Support only by email with long delays
- Pricing that changes with every conversation
- Pressure to sign immediately
The POS Software Scorecard
Rate each vendor from 1 (poor) to 5 (excellent). Multiply by the weight that matches your priorities, then total.
| Feature | Weight (1 to 3) | Vendor A | Vendor B | Vendor C |
|---|
| 1. GST billing and compliance | 3 | | | |
| 2. Offline mode | 3 | | | |
| 3. Barcode and billing speed | 3 | | | |
| 4. Inventory management | 3 | | | |
| 5. Payments and reconciliation | 2 | | | |
| 6. Returns, discounts, and offers | 2 | | | |
| 7. Roles, permissions, and audit | 2 | | | |
| 8. Customer management and receipts | 1 to 2 | | | |
| 9. Reports and multi-store | 2 | | | |
| 10. Hardware, security, support, pricing | 3 | | | |
| Total | | | | |
Tip: Raise the weight on features that match your business. A pharmacy should give more weight to batch and expiry tracking. A clothing store should weigh variants heavily.
7 Mistakes Shopkeepers Make When Choosing POS Software
- Buying on price alone. A cheap tool with poor support or missing features can cost more in lost sales and workarounds.
- Skipping a trial with real data. Demo data always looks clean. Test with your products.
- Ignoring cashier feedback. The people who use it all day should try it before you decide.
- Overbuying. Paying for advanced modules you will not use for two years.
- Underbuying. Choosing a basic billing app and then needing to migrate in six months.
- Forgetting hardware. Buying software first and discovering your printer or scanner does not work.
- Not checking exit terms. If you cannot export your data, switching later becomes painful.
A Simple 7-Day Plan to Evaluate and Decide
| Day | Action |
|---|
| Day 1 | Write down your needs, budget, and must-have features |
| Day 2 | Shortlist 3 vendors based on trade fit and reviews |
| Day 3 | Attend demos; use your own product list and scenarios |
| Day 4 | Test offline mode, returns, discounts, and reports |
| Day 5 | Let your cashier try billing for 30 minutes |
| Day 6 | Check support responsiveness; call a reference customer |
| Day 7 | Fill the scorecard, compare total 3-year costs, and decide |

“Giving cashiers limited permissions stopped unauthorised discounts. Our daily cash now matches the reports.”
Manager, apparel store (sample)
“The scorecard method made the decision easy. We compared three vendors on the same points instead of going by sales pitches.”

Frequently Asked Questions
1. What is the most important feature in POS software for India?
GST-compliant billing, reliable offline mode, and accurate inventory are the core three. After that, priorities depend on your trade.
2. Do I need cloud or desktop POS?
Cloud POS offers remote access, automatic updates, and backups. Desktop POS can work well in stable single-shop setups. Many modern products combine both with offline capability.
3. Is a free POS good enough?
It can work for very small or new shops. Check limits on invoices, users, and reports, plus support quality and data export.
4. How much does POS software cost?
It depends on the pricing model (subscription, one-time licence, or hybrid), users, stores, and add-ons. Compare the total 3-year cost, including hardware and support.
5. Will POS software file my GST returns?
It prepares return-ready data and reports. Filing is usually done through the GST portal or with your accountant. Some products integrate with filing tools.
6. Can I use my existing printer and scanner?
Often yes, but confirm compatibility with the vendor before buying.
7. How long does setup take?
A simple shop can be ready in a few days once the product list is ready. Larger catalogues and multi-store setups take longer.
8. What if my staff finds it difficult?
Choose a product with a simple interface and good training. Let staff test it before you decide.
9. Can I change POS software later?
Yes, but it takes effort. Pick a vendor that lets you export all your data, so you are never locked in.
10. Should I choose an industry-specific POS?
If your trade has special needs, such as expiry tracking, size and colour variants, or IMEI tracking, an industry-specific POS often saves time and prevents workarounds.
Conclusion
The best POS software for your shop is not the one with the longest feature list. It is the one that handles GST correctly, keeps billing running offline, tracks stock accurately, controls your cashiers, and comes with support you can rely on.
Use the 10 features in this guide as your checklist. Test each in a real demo with your own products. Score vendors fairly, check total costs, and involve the people who will use the system every day.
A few hours of careful evaluation now can save you months of frustration later.
