Customer-Facing Display Checklist for Retail Teams
A customer-facing checkout display is ready only when it shows the right sale, stays readable from the customer's position, and clears correctly between transactions. A powered-on screen is not enough. Before opening a new lane or returning a repaired display to service, test the whole customer journey with the store manager and an authorized POS administrator.
This checklist is for retail teams accepting a display installation or checking a changed checkout layout. It is not a payment-terminal repair guide or a substitute for your provider's setup instructions. Keep payment security settings intact, use an approved testing process, and avoid experimenting on a live customer's transaction.
Identify exactly what the screen is supposed to do
Write down the POS platform, display model, register identifier, connection type, and supported functions. Some screens show an itemized basket; others also collect customer input or provide payment prompts. Do not assume two screens with similar hardware support the same features. Confirm compatibility with the exact software edition and hardware combination before purchasing replacements.
Lightspeed's customer-facing display overview describes showing sale information such as items, quantities, discounts, and totals. Treat that as a platform-specific example, not a promise that every display supports every field. Your acceptance checklist should reflect the capabilities documented for your own installation.
Separate the customer screen from the cashier screen in your notes. Mirroring an entire employee desktop can expose information that does not belong in public view. Ask the authorized installer to demonstrate the intended customer-only interface, including what appears when the register is locked or the POS application is closed.
Check placement from the customer's side
Stand where a customer normally waits, then check the screen from more than one viewing height and angle. Look for glare from windows or overhead lights, small text, clipped totals, and signs or merchandise that obscure the display. The cashier being able to read it does not prove it is useful to customers.
Keep access and cable routing practical
Check that the display does not obstruct the payment device, bagging area, or normal counter access. If customers must interact with it, review reach and visibility with the people responsible for the store's accessibility requirements. Do not treat this operational walkthrough as a formal accessibility certification. Record problems for the installer rather than improvising mounts or stretching cables.
Use the manufacturer's approved mounting and power arrangement. Stop if you find a damaged connector, unstable stand, exposed wiring, unusual heat, or signs of liquid damage. Staff should not open equipment housings or change electrical connections. Keep the station out of service as appropriate and follow the store's escalation procedure.
Run a controlled basket test
Schedule the test away from active customer checkout. Use the provider's documented training or test mode where available, and confirm how it affects inventory and reporting. If the provider requires a real transaction, obtain the store's approval and follow its accounting procedure. Never invent payment-card details or repeatedly charge a card just to see whether the display changes.
Add one approved test item and compare its description and price on both screens.
Change the quantity and confirm the customer view reflects the current basket.
Apply an authorized test discount and compare the displayed adjustment and total.
Remove an item and confirm it disappears rather than remaining as a stale line.
Cancel the test using the documented process and confirm the customer view returns to its intended idle state.
If payment or receipt prompts are supported, verify their sequence through the provider-approved test procedure.
Compare results with the configured POS transaction, not a guessed calculation. If tax, discounts, or pricing are wrong on both screens, the display may simply be showing an upstream configuration problem. Record the discrepancy for the authorized owner. Do not change tax rules or product prices as an informal screen troubleshooting step.
Test the transition to the next customer
After the test, start another approved basket and confirm it appears on the correct lane. Check that details from the previous interaction are no longer visible. Review any loyalty, email, or receipt-entry screens for unintended personal information. Use fictitious test records permitted by your provider, and exclude customer information from photographs or support screenshots.
Separate connection failures from transaction problems
Describe the symptom precisely: blank screen, frozen basket, wrong lane, cropped content, or delayed updates. Note whether the cashier screen is functioning and whether another checkout has the same problem. Capture the first observed time and any recent approved change, such as moving the counter or replacing a cable.
A stale display does not establish whether a payment succeeded or failed. Check the transaction status through the POS provider's normal process before repeating any payment action. Follow the store's approved alternate checkout procedure while support investigates; do not bypass payment protections to keep the screen working.
Our IT support ticket template provides a useful structure for recording the affected lane, observed symptom, attempted actions, and business impact. Include model and connection details, but never passwords, full card information, or customer account data.
Record acceptance instead of relying on memory
Keep a short record containing the store and lane, equipment identity, test date, tester, expected result, actual result, and open issues. Give every unresolved item an owner. Mark the display accepted only after the agreed checks pass, or document a manager-approved limitation and its safe operating procedure.
For example, imagine a store moves a display to reduce glare. Basket updates still work, but the total is cut off at the new configuration. That is not a successful acceptance merely because the connection stayed active. The installer should correct the supported display settings, and staff should repeat the affected checks before signing off. This is an illustrative scenario, not a client case study.
Repeat the relevant checks after a display replacement, POS update, lane reassignment, or counter-layout change. Store the record where the next shift can find it. A clear handoff reduces uncertainty about which configuration was actually tested and which issue still needs attention.
