Changing Vending Prices? Check the Display and the Transaction

A price change is not complete just because a number has been saved in an office dashboard. Customers need clear information at the machine, and the final transaction should match the intended setup. Build a short acceptance check into every authorised vending price update.

Define the intended change first

List the machine, selection, product, old price, new price and planned change time. Specify who has approved the update and who will check the machine afterwards. Avoid broad instructions such as changing all drinks when different pack sizes need different prices.

Check the product map before editing prices. A correctly entered price against the wrong selection still produces an incorrect result. Our physical shelf and product map guide covers that first check.

Inspect every place customers see the price

Review shelf labels, selection screens and the payment terminal where applicable. Remove outdated temporary notices through the site’s normal process. Check that the price remains understandable before a customer commits to buying.

Not every controller and reader handles pricing in the same way. Nayax’s pricing configuration guidance illustrates why the controller and payment setup matter. It is not a reason to introduce extra payment charges; confirm the intended configuration with the supplier.

Make an agreed test purchase

Use the operator’s test procedure to select an affected item, observe the displayed price and check the resulting purchase record. Confirm that the item dispensed is the one named in the change sheet. Record which payment method was tested.

Where the installation supports several relevant purchase routes, ask the operator which require separate checks. Do not assume testing a single selection proves that every price update has reached every machine. Keep any test receipt with the change record.

Close the handover with evidence

Write down the test time, selection, expected price, observed price and result. If the values differ, escalate the mismatch and follow the operator’s process for preventing further incorrect sales. Do not leave the site team to explain a known discrepancy without a clear instruction.

Once checks pass, mark the change as complete and tell the refill team which labels or records have changed. Keep the earlier approved sheet for reference rather than relying on memory. A concise record makes later customer queries easier to investigate and helps the next person distinguish an intended change from a setup error.
