One combined snacks-and-drinks machine covers most Sydney workplaces up to about 80 people on site each day. Above that, split into a dedicated drink machine and a snack machine — two units. A 150-plus person site needs two to three machines, and a multi-floor building needs one per busy area. You don’t calculate this yourself. A full-service operator works it out from a free site check.
That’s the answer. The rest is the reasoning, the benchmarks, and why you never actually have to get the number right on your own.
The question usually sounds like this: “We’ve got 60 staff — do we need one machine or two?” Or “We’re on three floors, how many do we put in?” Both have the same short answer, and both are solved by the same operator who places the machine for free.
One Machine Covers More People Than You Think
The first instinct is to over-buy. Most venues picture one machine per 20 people, which is wrong by a factor of two or three.
A single combined machine holds roughly 300 to 500 items across snacks and cold drinks. That’s enough to cover a 20-to-80-person office for a normal restock cycle — one or two visits a week.
The machine doesn’t run out because 60 people each bought one thing on Monday. It runs out because 60 people each bought two things a day, every day, for a week. That’s the difference between a machine that’s always stocked and a machine that’s empty by Tuesday afternoon.
The Split Point Is Around 80 People
Around 80 people on site each day is where one machine starts struggling.
Below 80, a single combined machine sells out on schedule — the operator restocks it before it’s empty, and nobody notices. Above 80, the drinks drain faster than the snacks, and you end up with a machine full of chips and no cold water. That’s the signal to split.
The fix is two machines, not one bigger machine:
| People on site each day | What you need |
|---|---|
| Under 25 | One compact machine (or a small-office setup) |
| 25 – 80 | One combined snacks-and-drinks machine |
| 80 – 150 | Two machines — a dedicated drink unit and a dedicated snack unit |
| 150+ | Two to three machines, plus placement across busy areas |
These are planning benchmarks, not a formula you have to hit exactly. The precise answer depends on how much your team actually buys, which is why the operator measures it rather than guessing.
The Real Driver Is Foot Traffic, Not Headcount
Headcount is a proxy. What actually determines the number of machines is how many purchases happen in a day.
Three things move that number more than the total staff count:
- Shift patterns. A warehouse with two shifts of 40 has 80 daily users and needs the same machine count as an 80-person single-shift office — even though it’s “only 40 staff” at any one time.
- Food access nearby. A site five minutes’ walk from a café buys less from the machine than an isolated industrial estate where the nearest food is a 15-minute drive. The isolated site may need a second machine at a lower headcount.
- Type of work. Physical workers buy more than desk workers. A 60-person warehouse can out-purchase a 100-person office.
The operator’s job is reading these signals. Yours is giving them the numbers honestly — headcount, shifts, and whether there’s a food court next door.
Multi-Floor Buildings Need One Machine Per Busy Area
This is the mistake companies with 200-plus staff make most often: they put three machines in one break room on the ground floor and wonder why the second-floor kitchen is empty.
A vending machine serves the people within easy walking distance — a minute’s walk, give or take. Split across three floors, that means one machine per busy floor, not three in one room.
Placement beats count. One machine on every floor of a three-floor building outperforms three machines stacked in a single staffroom, because each one is now the closest option for the people around it.
You Don’t Do the Math — the Operator Does
Here’s the part that changes everything about this question.
When you buy vending machines, you have to get the count right up front, because every machine is capital you’re committing. Get it wrong and you’ve over-spent, or you’ve under-served the team and can’t fix it without spending more.
The zero-upfront full-service model removes that risk. The operator supplies the machines, stocks them, and earns from sales — so the operator is incentivised to get the count exactly right, and to add or swap machines as your site changes. You don’t buy the machines, so you’re never stuck with the wrong number.
This is the same reason how many staff you need for a free vending machine matters more than how many machines you think you want. The operator assesses the site and tells you.
Two Machines, Two Metres
If the answer is two machines, the space requirement doubles — but it’s still small.
A dedicated drink machine and a snack machine side by side take about two metres of wall and two square metres of floor, plus two power points. We covered the exact numbers in how much space a vending machine needs.
If the room can’t fit two, a single combined machine does both jobs in one footprint. The choice between one combined unit and two dedicated units is usually a space call as much as a demand call.
Which Machines for Which Count
Once you know the count, the type follows. The five machine types and where they fit:
| Machine type | Capacity | Right for |
|---|---|---|
| Combined snack + drink | 300 – 500 items | 25 – 80 people, one unit |
| Drink-only | 300 – 600 bottles/cans | Hydration-first sites, or the second machine above 80 people |
| Snack-only | 200 – 400 items | Break rooms with an existing drink fridge, or the second machine above 80 |
| Smart / cashless | Same, sells 15 – 25% more | Any high-traffic site; tap-to-pay is the default |
| Compact / tabletop | 40 – 100 items | Under 25 people, or a secondary spot |
The full breakdown is in types of vending machines for Sydney workplaces.
Start With One, Add When It Sells Out
If you’re unsure, the default is one combined machine. It covers the vast majority of Sydney workplaces, and it’s the cheapest thing to get right — because it’s free to you either way.
The operator watches the sales data remotely. When a machine starts selling out between restocks, that’s the signal to add a second — and because it’s the operator’s machine, the decision costs you nothing. You never have to predict demand perfectly; you just watch it happen.
The Bottom Line
One machine covers up to about 80 people. Split to two around 80 to 150. Go to two or three above that, and put one machine per busy area rather than stacking them in a single room.
You don’t need to work out the number yourself. A full-service operator does it from a free site check — and because the machines come at zero upfront cost, getting the count wrong never costs you money. It just means the operator adjusts.
Frequently Asked Questions
How many vending machines do I need for my staff count?
As a rule of thumb: one combined snacks-and-drinks machine for up to about 80 people on site each day, two machines (a dedicated drink unit and a dedicated snack unit) for 80 to 150 people, and two to three machines for 150-plus. The real driver is daily foot traffic past the machine, not total headcount on paper — and a full-service operator works it out for you from a free site check.
Do I need a separate drinks machine and a snacks machine?
Only once your site gets busy enough to empty a single machine between restocks. Up to roughly 80 staff, one combined machine covers both. Above that, splitting into a dedicated drink machine and a dedicated snack machine removes the bottleneck and stops the drinks running out while snacks sit unsold.
How many staff justify a second vending machine?
Around 80 or more people on site each day is the point where a second machine starts paying for itself. Below that, a single combined machine usually sells out on schedule rather than early. Shift-based sites reach the same threshold with cumulative daily traffic across all shifts — a warehouse running two shifts of 40 has 80 daily users.
What if my team works across multiple floors or buildings?
Count each busy area separately. A vending machine serves the people within easy walking distance, so a 200-person company split across three floors usually does better with one machine per busy floor than three machines crammed into one break room. Placement beats count.
Can one vending machine serve 100 people?
It can, but it will run dry between restocks. A single combined machine holds roughly 300 to 500 items, which is a lot — but a 100-person site buying at a typical rate empties it before the next restock run. At that size, two machines keep stock flowing and cut the risk of an empty machine at 3pm.
Do I have to work out the number of machines myself?
No. A full-service operator does this for you as part of a free site assessment. You provide the headcount, shift patterns and floor plan, and the operator recommends the right machine count, size and placement — and because the machines are supplied at zero upfront cost, adding a second one later costs you nothing out of pocket.
