Every operator eventually places a machine that disappoints. The difference between operators who build profitable routes and operators who quietly bleed money is not that the first group never picks a dud — it is that they find out fast, fix what is fixable, and move the machine when it is not. The tool for that is a structured 90-day test, decided in advance, with numbers instead of feelings.
Here is the framework: what to measure, the benchmarks at each checkpoint, the three fixes that actually move sales, and the decision rule at day 90.
Why 90 days — not 30, not forever
Thirty days is too short. A new machine needs two to three restock cycles before regulars form habits, and the first month is distorted by novelty purchases and by you still tuning the planogram. Judging at day 30 means pulling machines that would have matured into solid earners.
But "give it time" with no deadline is worse. A machine grossing $150/month at a weak site has a real cost: the cash tied up in the machine, the restock trips, and — biggest of all — the better location it could be sitting in instead. Ninety days is long enough for a true read and short enough that a mistake only costs you one quarter.
Set the expectation up front. When you sign the location, tell the contact you will review performance together after 90 days. That makes a later relocation a planned business decision instead of an awkward breakup, and a short trial period clause belongs in your agreement anyway — see vending machine contracts 101.
What to track from day one
You cannot run the test without data. At minimum, record per visit: gross sales since last visit, units sold by slot, and days elapsed. A card reader makes this automatic — remote sales data is half the reason the hardware pays for itself. If you are reading reports for the first time, start with how to read vending machine sales reports.
The single number that matters is sales per day, because visit intervals vary. A $210 haul looks fine until you realize it took 24 days to accumulate.
Picture the machines paying you while you sleep
That’s the real promise of vending — income that doesn’t cost you your time, and a life on your own terms. VendBuddy turns this guide into a step-by-step plan so you actually build it instead of just reading about it. Start free today.

Day 30 — signal check. A location that will eventually support $400+/month usually shows at least $8–10/day by the end of month one. Below $5/day at day 30 is a serious warning. You are not deciding yet — you are deciding how aggressively to intervene.
Day 60 — trend check. Sales per day should be flat or rising versus month one. The novelty bump is gone by now, so a 20%+ decline from month one means the early number was the ceiling, not the floor. If you made planogram changes at day 30, this is where you see whether they worked.
Day 90 — the decision. Compare average daily sales against what the site needs to clear your minimum. For most operators a full-size machine needs $13–15/day ($400–450/month) to be worth a recurring stop; a small countertop or honor-box site can clear at less. Know your number before you look at the data.
The three fixes worth trying before you pull a machine
Run these between day 30 and day 90, one at a time so you can tell what worked:
- Fix the planogram, not the people. Pull the bottom five SKUs by units sold and replace them with what the building's demographic actually buys — shift workers want energy drinks and meal items, not gum. Regional best-seller data beats guessing.
- Fix the price points. A machine full of $1.25 items at a site where people would happily pay $2.50 underearns at every vend. Conversely, premium pricing at a price-sensitive site kills transaction count. Here is when to adjust vending prices.
- Fix the spot inside the building. Ten feet matters. A machine around a corner from the break room does a fraction of one inside it. Ask the location contact about moving it next to the time clock, the lobby seating, or the main hallway — this is the cheapest fix with the biggest documented upside.
If sales are weak and you have not tried all three, you have a fixing problem, not a location problem. For a deeper diagnostic, see why your vending machine is not making money.
The day-90 decision rule
Keep: at or above your minimum daily number, or within 15% of it and still trending up. Fix and extend 30 days: below minimum but you have an untried fix from the list above — one extension only. Relocate: below 60% of your minimum after the fixes, or trending down at day 90. No machine earns its way out of a building with no traffic.
Relocating is not failure — it is the system working. The machine that grosses $150/month at the wrong site routinely does $500+ at the right one, and moving it yourself is very doable: how to move a vending machine solo.
The real cost of a dud location is the 90 days, so make sure the next placement clears a higher bar going in. Score replacement candidates before you commit using the location scoring checklist, and use VendBuddy's lead finder to line up a shortlist of nearby buildings — with decision-maker contacts — so the machine goes from a weak site to a vetted one in a single weekend instead of sitting in your garage.
FAQ
How long should I give a new vending location before judging it?
Ninety days, with checkpoints at 30 and 60. Shorter reads are distorted by novelty sales and planogram tuning; longer with no deadline just subsidizes a weak site.
What is a good daily sales number for one vending machine?
Most full-size snack or combo machines need $13–15/day ($400–450/month gross) to justify a recurring restock stop. High-traffic sites do multiples of that; see profit by location type for ranges.
Should I tell the location owner I am running a trial?
Yes. Framing the first 90 days as a mutual review period makes relocation a planned decision rather than a surprise, and it motivates the location to help — like agreeing to a better spot inside the building.
