A flat commission percentage is easy to explain. Tiered commission needs a little more care because the rate changes when takings reach an agreed band. A cash-up can be arithmetically correct and still cause an argument if the operator and site owner understood the bands differently.
A reliable check starts with the agreement and ends with a receipt or commission record both parties can follow.
Write down how the tiers work
Start with the commercial terms agreed for the machine. The record should answer five plain questions:
- Which machine or group of machines does the arrangement cover?
- What period is being assessed?
- Which takings figure is used for the calculation?
- Where does each band begin and end?
- Does a higher rate apply only to the money within that band, or to the whole amount once the threshold is reached?
That last point matters. People use the phrase “tiered commission” for more than one calculation method. If the agreement does not define it, confirm the intended method in writing before changing the rate in the operating record.
Do not mix up stepped and whole-amount rates
Consider an illustrative arrangement with takings of £180. The first £100 is set at 10%, and takings above £100 are set at 15%.
Under a stepped calculation, the first band produces £10 and the next £80 produces £12. Total commission is £22.
Under a whole-amount threshold calculation, reaching the second band applies 15% to all £180. Total commission is £27.
Neither example describes a particular VendMetrix account or customer agreement. It simply shows why naming the calculation method is more useful than writing “10% to 15%” beside a machine. The same takings and rates produce a £5 difference.
Make rate changes traceable
A new commission deal needs an effective date. Without one, the next collection can pick up a new rate even though some of the trading period belonged to the old arrangement.
Before editing a rate, record the date agreed with the site and decide how the change will apply if it falls between collections. You might use the old rate until the next complete period, or split the calculation where the records support that approach. The right treatment depends on the agreement. Write down the choice and apply it consistently.
Keep the old terms with the relevant historical period. Replacing them without a date makes an earlier receipt harder to explain later.
Check the machine before saving the cash-up
A quick sense check catches many avoidable mistakes. Before saving, confirm that:
- the correct site and machine are selected;
- the collection period matches the figures being counted;
- the current band limits and rates match the agreed terms;
- the calculation method is the one both parties expect;
- any charity contribution is treated separately and labelled clearly;
- the receipt will go to the right person in the preferred format.
Run a manual sample calculation when a tier is first introduced or changed. This controlled check confirms that the setup reflects the agreement before routine collections continue.
Give the site owner a figure they can follow
A receipt should show enough context to make the commission understandable. The useful details are the site, machine, collection date or period, takings used, applicable rate or band calculation, and commission total. If a charity amount also applies, label it separately rather than folding it into commission.
Consistency is more important than decorative paperwork. A site owner who receives the same clear structure each time can compare periods without asking which figure means what.
VendMetrix currently supports Bluetooth printed receipts and emailed receipts. Its site owner portal also lets site owners check commission history. These are confirmed features, but they do not replace the need to agree the underlying commercial terms.
Review the pattern, not just one collection
A single high or low collection may have an obvious explanation, such as a longer interval between visits. Review several periods before treating a change as a trend. Look at takings, visit frequency, commission totals and any rate changes together.
The current VendMetrix features page lists monthly takings, year-on-year comparisons, charity totals, visit counts and printable summaries among its reports. Those views can support a periodic commission review, while the written agreement remains the authority for the rate itself.
Where VendMetrix fits
VendMetrix is a vending-round cash-up and administration product. Its current features include machine-level commission settings with support for tiered rates and charity contribution models. During cash-up, the product uses the configured site information to calculate commission. It also keeps receipts and commission history alongside the round records.
The product was built around the day-to-day work of a vending operator, as explained on the VendMetrix story page. For tiered commission, the practical benefit is having the agreed setup, cash-up result and follow-up record in the same operational process.
A sound tiered commission process defines each band, dates every change, tests the setup and gives the site owner a record that can be checked later.
