POS Functionality Checklist
A comprehensive point of sale testing checklist for verifying user access, product lookup, prices, discounts, tax, payments, returns, receipts, loyalty, inventory updates, hardware, offline mode, reconciliation, and reporting.
About this checklist
What a POS functionality checklist should help you verify
Use it to test the complete transaction journey from login and item scan through payment, inventory update, receipt, shift close, reconciliation, and reporting.
Why teams use it
To replace informal POS spot checks with repeatable test scenarios, expected results, evidence, defect ownership, controlled retesting, and formal approval.
What is included
- Login, role permissions, product search, barcode, price, tax, and promotions
- Payments, returns, refunds, receipts, customer profiles, and loyalty
- Inventory, omnichannel orders, hardware, connectivity, and integrations
- Shift close, reconciliation, reports, incidents, retesting, and sign-off
Who should complete it
A trained store tester, retail IT analyst, implementation specialist, or QA owner runs the checklist, while finance, payments, operations, product, and engineering own relevant actions.
Complete checklist structure
POS checks across every major transaction and control area
Use these 60 questions as a starting point, then adapt them to your store format, markets, payment methods, tax rules, products, customer journeys, integrations, and approval process.
Test setup and transaction scope
- Select the store, POS terminal, device, application version, business date, and test environment being reviewed.
- Confirm the test user, assigned role, shift, and permission level match the scenario being tested.
- Verify the terminal displays the correct store name, terminal number, date, time, currency, and trading status.
- Confirm the latest approved product, price, tax, promotion, tender, and loyalty configuration has synchronized to the terminal.
- Review unresolved POS incidents, repeat defects, release notes, and previous test findings before starting the checklist.
- Confirm the approved rules for test transactions, customer data, payment test cards, screenshots, and evidence retention.
Login, user access, and role permissions
- Verify a cashier can log in with valid credentials and is assigned to the correct store, terminal, and shift.
- Test invalid password handling, retry limits, lockout behavior, and password reset or support flow.
- Verify supervisor authorization is requested for restricted actions such as voids, overrides, refunds, and drawer access.
- Confirm each role can access only the menus, reports, tenders, discounts, and transaction functions approved for that role.
- Verify automatic logout, screen lock, session timeout, and user switching work without exposing the previous user session.
- Test shift opening, till assignment, opening float entry, and cash drawer association for the logged-in user.
Product lookup, barcode, pricing, and promotions
- Scan a standard barcode and verify the correct product description, SKU, unit, tax category, and selling price appear.
- Search for a product by SKU, name, category, or alternate identifier when the barcode is unavailable.
- Test alternate barcodes, weighted products, variable-price items, bundles, and pack-size conversions where applicable.
- Verify the POS selling price matches the approved price master, shelf label, promotional communication, and effective date.
- Test automatic promotions, coupons, bundles, buy-one-get-one offers, and start or end date rules.
- Verify blocked, recalled, expired, restricted, or unavailable products cannot be sold without the required warning or approval.
Cart, quantity, discount, tax, and total calculation
- Add items, remove items, change quantities, and verify the cart updates without duplicate or missing lines.
- Apply approved line-item and basket-level discounts and verify authorization, limits, reason codes, and audit trail.
- Enter a coupon or promotion code and verify validation, eligibility, expiry, single-use rules, and customer messaging.
- Verify tax is calculated correctly by product, location, customer type, transaction type, and tax-exemption rule.
- Confirm currency, decimal precision, rounding, minimum charge, and change calculation follow the approved market rules.
- Verify subtotal, discount, tax, fees, deposits, and final payable amount recalculate correctly after every cart change.
Payments and tender processing
- Complete a cash transaction and verify amount received, change due, drawer opening, receipt, and cash ledger entry.
- Complete chip, swipe, and contactless card payments supported by the business and verify approval details are returned once.
- Test split tender using two or more approved payment methods and verify the remaining balance updates correctly.
- Test gift cards, store credit, vouchers, and loyalty value for balance checks, redemption, partial use, and expiry rules.
- Complete approved mobile wallet, QR, online link, or alternative payment methods and verify confirmation reaches the POS.
- Test declined, timed-out, cancelled, reversed, and retried payments to confirm no duplicate charge or duplicate sale is created.
Returns, exchanges, refunds, voids, and cancellations
- Process a return with the original receipt and verify item, quantity, price, tax, reason, and eligibility are retrieved correctly.
- Test a return without receipt and verify identity, value limit, manager approval, tender, and fraud controls.
- Complete an exchange for an item of equal, lower, and higher value and verify the balance calculation and receipt.
- Verify refunds are sent to the approved original tender or controlled alternative and cannot exceed the original paid amount.
- Void an item and cancel a transaction before payment, then verify reason codes, approval, stock, and audit trail.
- Test post-payment cancellation or reversal and confirm the POS, payment terminal, inventory, receipt, and reports reconcile.
Receipts, invoices, customer profiles, and loyalty
- Print a receipt and verify store details, transaction number, items, quantities, prices, discounts, tax, tender, date, and time.
- Send a digital receipt by approved channel and verify consent, masked contact details, delivery status, and content.
- Generate a tax invoice or business receipt and verify customer, tax registration, address, and invoice sequence fields.
- Search, create, and update a customer profile while verifying duplicate detection, required fields, and access permissions.
- Earn, redeem, reverse, and adjust loyalty points or rewards and verify balance, eligibility, and receipt messaging.
- Confirm customer consent, privacy notices, data masking, opt-in choices, and deletion or correction requests work as designed.
Inventory, orders, and omnichannel workflows
- Complete a sale and verify on-hand stock, available stock, reserved stock, and item movement update correctly.
- Test low-stock, zero-stock, and negative-stock rules and verify warnings or sale restrictions follow policy.
- Retrieve and complete a click-and-collect or pickup order and verify customer, items, payment, status, and handover evidence.
- Create or complete a home-delivery or ship-from-store order and verify address, delivery charge, inventory reservation, and status.
- Test reservation, layaway, deposit, pre-order, or hold functions used by the business.
- Verify POS sales, returns, transfers, orders, and reservations synchronize once with inventory and order systems.
Hardware, connectivity, offline mode, and integrations
- Test barcode scanner accuracy, scan speed, duplicate-scan handling, and fallback manual entry.
- Test receipt printer, paper status, print quality, cutter, reprint, and printer-failure handling.
- Test cash drawer opening, locking, no-sale access, manual override, and drawer event logging.
- Verify payment terminal, customer display, scale, label printer, signature device, and other connected hardware communicate correctly.
- Test approved offline mode, transaction limits, user warnings, receipt behavior, and synchronization after connectivity returns.
- Verify payment, ERP, inventory, tax, loyalty, CRM, and reporting integrations process each transaction without loss or duplication.
Shift close, reconciliation, reporting, incidents, and sign-off

How to use it
Turn POS testing into a controlled release and store-readiness workflow
The questions define what to test. Standard scenarios, expected results, evidence, severity, ownership, deadlines, retesting, and approval make the process reliable and auditable.
Define the scenario
Set the store, terminal, software build, test user, product, payment, expected result, and business rule before execution.
Run controlled tests
Use approved test data, payment methods, products, customer records, and evidence rules.
Capture proof and defects
Record actual results, screenshots, receipts, transaction references, severity, owner, due date, and reproduction steps.
Retest and approve
Close defects only after a controlled retest confirms the fix across the POS and connected systems.
