POS System Features Checklist: 25 Must-Have POS Features (2026)

The POS features that matter most are fast barcode checkout with split payments, stock that updates on every sale, offline selling, customer credit and loyalty, shift cash-up reports and staff permissions. This POS system features checklist lists 25 in six groups, with what to test in a demo.
Choosing a POS without a checklist is how businesses end up with software that does not fit how they work. Use the list when comparing vendors, during demos, or to audit the system you have.
What features should a retail POS system include?
Every retail POS should cover the essentials in the first two groups below: checkout and inventory. Customer, reporting, hardware and integration features decide how well it fits as you grow. The printable table at the end marks what is essential and what depends on your business.
POS software features for sales and checkout (essential)
- Multiple payment methods: cash with change, card, bank transfer, mobile wallets and split payments across them.
- Barcode scanning: USB or Bluetooth scanners, plus search by name or SKU when a label is missing.
- Discounts and promotions: line and basket discounts, percentage or fixed amount; ask about multi-buy offers if you run them.
- Tax management: several tax rates, tax per item, tax shown on the receipt and reported for filing.
- Receipt customisation: your logo, contact details, return policy and message, in the paper sizes your printers use.
- Offline mode: selling continues when the internet is down and syncs when it returns. Essential where connections are unreliable.
Inventory features (high priority)
- Real-time stock updates: every sale, return and adjustment shows immediately on every till and location.
- Low-stock alerts: a threshold per item, shown on the dashboard or sent as a notification.
- Purchase orders: raise, send and receive POs; turn low-stock items into a PO quickly.
- Multi-location inventory: see, transfer and manage stock across branches and warehouses from one login.
- Batch and expiry tracking: essential for pharmacy, grocery and food; batch numbers, expiry dates and near-expiry reports.
- Variants and units: size and colour variants under one product, and one item sold in several units (box, pack, piece). Essential for garments, cosmetics and hardware.
- Bundles and recipes: combo products and bills of materials that deduct component stock.
Customer features (medium priority)
- Customer profiles: contact details, purchase history, balance and notes.
- Loyalty: points earned and redeemed at checkout.
- Credit accounts: sell on credit with limits, statements and aging.
- CRM and messaging: customer records linked to follow-ups and SMS, email or WhatsApp campaigns.
Point of sale software features for reporting (high priority)
- Daily sales summary: revenue, transactions, average sale and payment-method breakdown, live.
- Product performance: top sellers, slow movers, dead stock and margin by product.
- Staff performance: sales by cashier and salesperson, refunds and shift cash differences.
- Inventory valuation: stock value at cost, for the accounts and insurance.
- Filterable, exportable reports: filter by date, branch, product or customer and export to Excel or CSV.
Hardware compatibility (practical)
- Peripherals: receipt printers (thermal and A4), cash drawers, barcode scanners, label printers and, if you sell by weight, scales.
- Devices: runs on the computers, tablets or phones you plan to use at the counter.
Integrations and scalability (future-proofing)
- Accounting: sales post to the books automatically, either through a built-in accounting module or a tested link to your accounting package.
Bonus features worth asking about
- E-commerce: online store orders and stock in the same system.
- Mobile POS: selling from a phone or tablet away from the counter.
- Kitchen display: for restaurants, orders sent to a kitchen screen instead of paper.
- Table management: orders tracked by table for dine-in.
- Multi-currency: if you buy or sell in more than one currency.
- Role-based access: what cashiers, supervisors and managers can see and do.
POS system functional requirements: turning the checklist into a requirements list
A checklist tells you what exists; functional requirements say what your business needs it to do. Rewrite each item you care about as a testable sentence, give it a priority, and note how you will test it:
| Requirement | Priority | How to test |
|---|---|---|
| A cashier can split one bill between cash and card | Must | Ring up a sale and pay part of it each way |
| Selling continues when the internet drops | Must | Disconnect, sell three items, reconnect, check stock |
| One item sells in boxes and pieces with stock converted | Must (if relevant) | Sell 1 box and 3 pieces, check stock |
| Expiring stock is listed 30 days ahead | Must (food/pharmacy) | Receive a batch with a near date, run the report |
| Credit sales stop at the customer's limit | Should | Sell above the limit and see what happens |
| End-of-shift report shows expected vs counted cash | Must | Close a shift with a deliberate difference |
Send the list to every vendor and ask them to answer line by line, then test the "Must" lines yourself.
How to use this checklist during a demo
- Ask the vendor to show each feature live, not on slides.
- Test edge cases: partial payments, returns, transfers between locations.
- Ask: "What happens to my data if I cancel?" and "How do I export it?"
- Run a trial of at least two weeks on your own products and hardware before committing.
