Service at an exhibition centre, Written Down Instead of Guessed

Before the Table: What This Is

This note looks at tech for 3 units over 5 months at an exhibition centre, written from the buyer's side of the table. The figures are modelled rather than measured: cup volumes, price per cup and cost lines follow stated assumptions, and the arithmetic is left visible so a reader can substitute their own numbers.

Six Inputs and Where They Came From

Cup volume is stated per unit per day. Revenue is cups x 30 days x units x price per cup, taken at 10.2. Cost is consumables, the site share, power and parts. Payback is equipment spend divided by steady monthly net. No figure here is a quotation.

The model keeps the ramp separate from the steady state: the early months carry a lower cup count, and the steady figure is the plateau the site settles into once regulars appear. A reader who expects a different ramp can replace it without disturbing anything else on the page.

One Table, Seven Lines

The columns are shown separately because the argument is rarely about the total. It is about which line moves fastest when a site underperforms, and which lines were fixed before the first cup was sold.

What the Table Says First

The best month in this model nets about 5972, the weakest about 4048. The gap is the site's own variability rather than a change in cost, and that gap is what a trial period exists to measure.

At the modelled plateau, payback lands at 14.2 months. Read it as a reading of these assumptions, not a forecast: halve the cup volume and the same placement reads very differently.

Consumables scale with sales, so they rarely surprise anyone. The site share and the route hours are the two lines that do surprise operators, because both are agreed before the first cup and neither moves when the site underperforms.

service in Six Rows

Most service calls are not failures. They are stock, cups, a socket or a screen waiting for someone to press a button, and each one costs a visit if nobody sorts the categories.

Telemetry has changed what unattended means. Stock, faults and sales report themselves, which moves the operator's job from finding problems to deciding which problems matter this week.

The useful split is between what a dashboard can see and what only a visit can see. Routes built on that distinction are shorter than routes built on habit.

The Second Question Buyers Ask

Placement paperwork fails on the dull clauses: access hours, who pays for power, what happens when the host changes the use of the space, and how either side leaves.

The exit clause carries more value than the rate. A placement that cannot end without penalty is a bet that has to win; one with a written move-out is a test that can fail cheaply.

Six Things to Confirm

1. Check what the dashboard reports and what it omits
2. Record the first three faults with date, part and cause
3. Decide the escalation path before the first failure, not after
4. Write access hours and the power arrangement into the agreement
5. Agree the move-out term and the notice period in writing
6. Confirm the trial period and the move-out term before delivery
7. Write the modelled cup volume into the plan and review it after month one

How to Reproduce This at Your Own Site

The arithmetic is short enough to redo in an afternoon. Do it in this order:

1. Write down cups per day for seven days, including the slow ones
2. Read the price per cup and the consumable cost off two actual invoices, one month apart
3. Add the host share, the power bill and the spare-parts line as three rows
4. Divide equipment plus installation by the steady net and round outward, never inward
5. Repeat the calculation at half the cups; the difference between the two runs is the risk

Four Venues, Four Different Curves

Traffic arrives on a schedule in every venue, and the schedule differs. Four common shapes, and what each one moves first.

The point of the list is not to rank venues but to predict which line will move. Match the cadence to the rhythm and the rest of the ledger behaves.

What Survives the Meeting

Start with this: a ledger is a negotiating document. It is only useful if the other side can see which line you disagree with.

The trial is the only instrument that turns a guess about a venue into evidence, and it is priced in one clause: the move-out term.

Third, write down the cup volume you are planning for. A placement that hits its volume and misses its margin is rare; a placement that never reaches the volume is common, and a written number makes that visible in month two rather than month ten.

The Inputs That Would Flip It

The model is sensitive to volume first, the host share second, and access third. Two of those three are negotiable before signature.

The useful reply to a better number is a request for its assumptions. Nine times out of ten the gap is a cost line that was left out rather than a saving that was found.

Common questions

What should a dashboard actually report?

Stock depth per line, faults with timestamps, sales by hour and the machine's online state. Anything beyond that is useful only if someone reads it weekly.

Does remote monitoring reduce service visits?

It changes them rather than removing them: fewer emergency visits, more planned ones, and a better guess at which part to carry.

What do the modelled numbers actually mean?

They are the arithmetic of stated assumptions, not measurements. Every input is listed in the assumptions section so a buyer can replace it with their own.

Why show six months instead of a full year?

Because the first six months contain the decision: the ramp, the plateau, and the first sign of which cost line moves when the site underperforms.
