Stocking a vending machine isn’t just “fill it up and hope for the best.” The goal is to keep your best sellers available, reduce slow-moving dead stock, and make sure customers can always find something they want. If you use a basic routine and track what’s working, your machine stays full, looks professional, and earns consistently.

Start by learning your location. A warehouse or transport depot usually sells more energy drinks, water, iced coffee, chips, and chocolate. Offices often do better with sugar-free options, protein snacks, nuts, muesli bars, and a mix of treats. Public areas can be different again, with more “grab-and-go” favourites. Your first stock run should be a balanced starter mix, but the real magic is adjusting based on sales.

Use the “80/20 rule”: about 20% of your items will usually generate most of your sales. Identify those winners quickly and give them more space (more “facings”). If water and iced coffee always sell first, increase the number of rows or spirals allocated to them. If a snack sits for weeks, reduce its space or remove it entirely. The biggest mistake is treating every item as equal.

Rotate stock properly. Always put newer stock behind older stock so the older items sell first (first in, first out). Check expiry dates every visit, and don’t overstock slow items just because you got a bulk deal. A machine that has expired products or dusty rows kills trust fast, and customers stop using it.

Plan servicing like a schedule, not a reaction. High-traffic sites might need weekly top-ups; smaller sites might be fortnightly. On every visit, do a quick wipe-down, remove damaged packaging, check coin mechanisms (if used), and test a few selections. Reliability is part of stocking.

Finally, keep it simple: track sales with a note on your phone or a spreadsheet—what sold out, what didn’t move, and what people asked for. Over time you’ll build a custom product mix that fits that location perfectly. Stocking becomes faster, waste drops, and the machine stays profitable without guesswork.
