Guests can check an order and its amount before payment only if the POS and compatible customer-facing display show the right details at the right time. Ask to see that flow on the actual proposed setup. A screen that shows a total alone may not give a guest enough information to catch a missing modifier or incorrect item.
Start with a normal counter order, then add a modifier, apply a discount and correct an item. Watch what appears on the guest side before the cashier starts payment. Your decision is not just whether a second screen can connect; it is whether the guest has a useful chance to review the order.
Map the guest view from order entry to payment
At a busy counter, the cashier needs to enter an order quickly while the guest needs enough time and information to check it. The person handling payment also needs to know when the amount is final. A good demo makes each of those moments visible.
Ask the vendor to walk through the flow in the order your staff would use it:
- Enter an item and show what the guest sees.
- Add a modifier and confirm whether its name and price appear.
- Add another item and apply a discount.
- Correct the order and show the updated details and amount.
- Pause before payment so the guest can review the final order.
- Show what the guest sees when payment begins, without taking a real payment.
Look for the handoff between ordering and payment. Does the item list stay visible until the guest has had a chance to read it? If a payment prompt replaces the order, can the cashier return to the order view? Ask the vendor to demonstrate the answer rather than assuming every setup behaves alike.
The display also needs to distinguish an item price from the amount due. Ask where discounts, taxes and any other charges appear, and when the final payable amount is shown. A guest should not have to infer whether a number is a subtotal or the total to be paid.
Consider your own service style. A coffee counter may need a quick glance at a drink and milk choice. A counter serving larger family orders may need the guest to review more lines. If the display shows only part of a long order, ask how the remaining items can be viewed before payment.
Run a sample order with a correction
Use the following hypothetical order as a simulation, not a live sale. The amounts are sample item prices, not a vendor quote. For this arithmetic exercise, the total excludes taxes and other charges; in your actual demo, ask how applicable charges appear before payment. Use a training or test environment that cannot take a real card payment, send a guest message or dispatch a courier.
| Step | Sample entry | Amount to check | Guest-view question |
|---|---|---|---|
| 1 | Sandwich, $12; modifier, $2 | $14 | Are the sandwich and modifier named separately or clearly connected? |
| 2 | Add a $5 drink | $19 | Can the guest see all three details and their prices? |
| 3 | Apply a $3 discount | $16 | Is the discount visible and is the updated amount clear? |
| 4 | Remove the drink | $11 | Does the drink disappear and does the amount update before payment? |
The table gives you expected results to compare with what appears on the screen. The final amount is $12 plus $2 minus $3, or $11. Ask the vendor to use a discount that remains valid after the drink is removed. If the system applies different discount rules, record the rule and recalculate the expected amount before deciding whether the result is correct.
Have one person enter the order and another stand where a guest would. The guest-side observer should say what they can see without looking at the cashier's screen. Record whether the modifier, discount and correction are understandable, not merely whether the arithmetic is right. A correct total does not explain an incorrect sandwich.
Try one correction that resembles your own menu, such as changing a side or removing an add-on. Ask whether the guest sees the revised item immediately and whether an old line remains visible in a way that could cause confusion. If a change requires the cashier to refresh a view or repeat an action, note that extra step.
Keep the result alongside the vendor's explanation. Separate what you saw on the proposed device from what the vendor says another model or configuration can do. If the answer depends on a setting, ask for the setting and its effect in writing. A promise about a future configuration is not the same evidence as a working demonstration.
Check placement, visibility and compatibility
Bring the counter layout into the decision. A screen can display every detail correctly and still be hard to use if it faces the wrong direction or is blocked by a payment terminal. Ask for a demonstration at the intended counter height and viewing distance, or set up a reasonable mock counter if the equipment cannot be installed yet.
Check the view from where guests actually wait, including from a seated position and from either side of the counter. Can they read item names and amounts without leaning across the counter? Is glare a problem under your lighting? Ask whether text size, contrast, angle or placement can be adjusted on the proposed device. Do not assume an adjustment is available because it exists on another screen.
Also consider privacy and space. Decide whether a guest can review the order without exposing more information than necessary to the next person in line. Check that staff can still reach the payment device and that cables or stands do not crowd the work area.
For example, a display might pass the sample-order check when viewed straight on but fail your decision if a guest seated at the counter cannot read the total from the available mounting position. In that case, ask about another placement or device and repeat the check. If neither gives the guest a usable view, do not treat the first pass as sufficient.
Before comparing setups, list the equipment you intend to keep: model, operating system where applicable, connections and payment processor. Ask the vendor to confirm compatibility with the exact POS and customer-facing display configuration. An existing tablet or terminal is not automatically reusable. Fleksa's hardware page is a starting point for discussing equipment; confirm the particular combination before buying.
Ask what the display requires to connect and operate, who installs it, and what happens to the guest view if the connection drops. If a separate payment device is involved, ask how its screen relates to the order display. A connection to the POS does not by itself establish that item details will remain visible through the payment handoff.
Compare evidence before choosing
Use the same scenario and viewing positions for each setup you consider. Give each requirement a simple result: demonstrated, needs clarification or does not meet your needs. Attach a short note describing the screen, configuration and action. This makes it easier to compare an actual demonstration with a verbal answer.
Set your must-haves before the demo. For a counter where guests often customize meals, visible modifiers and a readable correction may be essential. For a small counter with limited space, the available mounting position may be the deciding constraint. A setup should meet the requirements that matter to your service, not just offer a long list of features.
Use this checklist to finish the comparison:
- Item accuracy: Can the guest identify each item and its relevant modifier? Does a correction replace the old information clearly?
- Price visibility: Are individual prices, the discount and the amount due understandable? Are applicable charges shown before payment?
- Review time: Can the cashier pause for review before the payment prompt? What happens if the guest spots a mistake at that point?
- Accessibility and placement: Can people read the screen from the positions available at your counter? Which display adjustments are actually supported?
- Compatibility: Has the vendor confirmed the exact display, POS, connections and processor setup in writing?
- Exceptions: What happens with a longer order, a connection interruption or a discount whose eligibility changes after a correction?
For anything marked needs clarification, name the person responsible for answering and ask for the answer before selection. If you cannot see a feature on the proposed setup, ask for a demonstration or written confirmation specific to that configuration. Keep the vendor's quote with the compatibility confirmation so you know which equipment and setup it covers.
After the simulation, a separate live service pilot can reveal whether the placement and review step fit normal counter work. Agree on its scope with the vendor and staff first. Unlike the simulation, a live pilot involves actual service, so use your normal procedures for real orders and payments.
For broader setup questions, see Fleksa's POS questions and its overview of restaurant management software. Then request a POS demo using the sample scenario, and ask the vendor to document the display, configuration and outcome.
Frequently asked questions
Does a customer-facing screen always show the full order?
Not necessarily. Ask to see a representative long order on the proposed setup, including how a guest can view any lines that do not fit on the screen before payment.
Can I use an existing tablet as the guest display?
Possibly, but do not assume it will work. Give the vendor the tablet model, operating system and intended connections, and request written confirmation for the complete setup.
Should I test the display with a real payment?
No real payment is needed for the sample-order simulation. Use a test environment that cannot charge a card, message a guest or dispatch a courier. Evaluate actual service separately in an agreed live pilot.
