A pilot should answer a decision question: whether the location, assortment and operating plan justify a longer commitment. Installing a machine temporarily and looking at the sales total is not enough. Without clear conditions, a poor setup can be mistaken for weak demand, or an unusual event can make an ordinary site look exceptional.
Agree the pilot arrangement with the property and relevant suppliers before installation. Document permissions, responsibilities, costs and the process for removal or continuation. A temporary installation still needs suitable access, utilities and safe operation.
Choose the main uncertainty. It might be demand at the position, the product mix, the refill workload or customer use of a payment method. Keep the scope manageable so the result can be interpreted.
Write the decision criteria before seeing the results. Include the operating contribution needed, acceptable service demands and any essential reliability or product-condition requirements. Do not move the goalposts simply because the early sales figure is encouraging.
Offer products, prices and payment methods close to the intended long-term operation. If the pilot uses heavy discounts or a staffed promoter, record that difference. Those conditions may be useful for a separate test, but they should not be treated as ordinary unattended demand.
Make sure the machine has been commissioned with the actual products. A pilot dominated by delivery faults does not provide a clean demand test. Record any configuration limitation that affects the offer.
Cover the site's normal trading pattern, including relevant busy and quiet days. Avoid judging a workplace only during a holiday closure or a venue only during a major event. The required period depends on the business and the variation you need to observe.
Record unusual conditions such as weather, construction, promotions or temporary competition. They do not make the results useless, but they change how confidently the data can be applied to future operation.
Track when key products are out of stock and when the machine cannot accept purchases. Low recorded sales during those periods do not establish low customer demand. Keep payment failures, jams and other interruptions visible in the review.
Record the product mix and changes made during the trial. If several variables change at once, it becomes difficult to know what caused the result. Make planned adjustments in a documented sequence where practical.
Record picking, travel, refilling, cleaning and support time. Include waste, payment fees, site charges and relevant recurring services. Owner labour should not disappear from the model simply because no wage was drawn during the pilot.
Separate one-time pilot setup costs from ongoing costs, while keeping both visible. The first answers what the trial cost; the second helps estimate ordinary operation. Neither should be hidden to make the result look better.
Look for repeated questions about product choice, price clarity, payment or collection. Use a proportionate feedback method and avoid collecting unnecessary personal information. A small number of detailed complaints can reveal a fixable usability issue.
Do not equate positive comments with purchases. Combine feedback with observed behaviour and transaction records. Someone liking the idea of a machine does not necessarily mean they will use it regularly.
Compare the result with the original criteria and explain any remaining uncertainty. Avoid projecting one strong week across a full year without accounting for the site's normal variation.
Use the traffic assessment, break-even calculation and site survey to prepare a pilot that produces a usable purchasing and location decision.
