Collection intervals are often inherited rather than chosen. A site goes on a fortnightly round because that is how it has always been done, even after takings, access hours or the machine mix have changed.
The right interval is the one that keeps the machine serviceable, the cash position controlled and the journey worthwhile. It will not be identical across a round, and it should not be treated as permanent.
Start with the reason for visiting
Collection is only one reason to attend a machine. A visit may also be needed to refill products, inspect equipment, deal with a fault or speak to the site contact. Those needs can run on different timetables.
Write down the factor that normally triggers each visit. For a coin-operated tower, cash capacity or an agreed collection routine may lead. For another machine, stock availability or cleaning may require attention sooner. If two tasks have different natural intervals, decide whether combining them saves a journey or leaves the machine unattended for too long.
A fixed schedule is useful for planning, but it needs an exception rule. The operator should know what justifies an earlier visit and who can change the plan.
Use comparable collection figures
A large cash-up does not prove that a machine needs more frequent visits. First check how many trading days the money covers. Compare takings per day or complete calendar periods rather than placing a six-week collection beside a three-week collection.
Look at several normal periods. One unusually busy weekend or a temporary closure can distort the result. Record known reasons for a change, including school holidays, venue closures, machine faults, product shortages or a move within the premises.
Keep gross takings separate from commission and the operator’s retained amount. Gross takings help show customer demand; retained cash helps with commercial review. Neither figure alone tells you whether the journey is worthwhile because staff time, mileage, product cost and servicing work also matter.
Our guide to comparing vending machine performance fairly covers these checks in more detail.
Check capacity before stretching the interval
A slower visit cycle may reduce driving, but only if the machine can cope with it. Consider coin capacity, product capacity, battery or power needs, cleaning requirements and the consequences of a fault remaining unnoticed.
Do not use the theoretical maximum as the working limit. A machine regularly reaching full coin capacity before collection has no room for a busy spell. The same applies to a popular product line that empties days before the rest of the machine.
Cash exposure deserves a separate decision. The amount an operator is prepared to leave on site depends on the equipment, location, insurance conditions and the business’s own controls. A route plan should reflect that decision rather than allowing cash to accumulate simply because a site is inconvenient to reach.
Include site access and service time
Two nearby sites are not necessarily equally easy to service. Record access windows, parking arrangements, signing-in requirements and the time normally spent at the machine. A ten-minute collection can become a forty-minute stop if loading access is restricted or the site contact is only available at certain times.
Ask whether commission must be handed over or acknowledged during the visit. If the operator needs an authorised person present, that condition belongs in the route record. It is better to plan around a known window than to arrive quickly and leave without completing the job.
Test the effect on the whole round
Changing one interval alters the surrounding route. Moving a remote site from every two weeks to every three may save mileage, but it can also break a useful cluster of nearby stops. Look at the day as a whole before changing the calendar.
Build enough time into the route for collections, receipts and conversations with site contacts. The Health and Safety Executive’s guidance on planning work journeys says schedules should account for traffic, road conditions and the time needed for administrative and customer-facing tasks. A round that only works when every road is clear and every cash-up is perfect is not a sound plan.
Keep a small amount of spare capacity in the day for faults, access delays and extra counting. Otherwise, the final stops are the ones most likely to be rushed or repeatedly postponed.
Set a trial interval and a review date
Choose an initial interval from the evidence available, then treat it as a trial. Record the start date, the reason for the change and what would make you reverse it. Review after several comparable collections rather than after the first visit.
At the review, check:
- whether cash or products approached practical capacity;
- whether faults or empty selections lasted too long;
- the average time spent on site and travelling;
- whether planned visits were completed on time;
- whether the site contact raised any service concerns.
Change one important variable at a time where possible. If the interval, machine position and product mix all change together, it becomes difficult to tell which decision affected the result.
Keep the interval attached to the site history
The schedule should sit alongside the records that explain it. VendMetrix currently provides due-visit prompts, route planning, cash-ups, visit counts and monthly site and machine reports. Operators can choose the sites due a visit, plan a round trip and open directions in Google Maps, Apple Maps or Waze. These confirmed tools are listed on the VendMetrix features page.
Those records can show when collections happened and how machine takings changed. They do not remove the operator’s judgement about capacity, access, security or service standards. Record the reason for an interval change so the next review is based on the decision that was actually made, not on somebody’s memory of it.
A collection calendar should move when the round moves. Review it when trading patterns change, a machine is replaced, the venue alters its hours or repeated route delays appear. That keeps visits tied to the work each site needs instead of to an old diary entry.
