We set up coffee solutions for Belgian offices every week, and the pattern we see most often is this: a facility or office manager picks a machine based on headcount alone, then discovers six months later that the morning rush creates a queue, the beans run out on Thursdays, or the maintenance costs were never factored into the budget. Our office coffee setup process starts with consumption modelling, not machine specs, because the machine is the last decision, not the first.
This guide covers the three machine types that work for teams of 10 to 100, how to calculate capacity honestly, and how to think about total cost so you're not surprised twelve months in.
Which machine type fits your office?
Three machine formats cover the vast majority of offices in this size range. Each has a clear use case, and the wrong choice creates daily friction.
Fully automatic (volautomaat) is the default choice for most offices between 15 and 100 staff. One button delivers a consistent espresso, lungo, or cappuccino without any barista knowledge. The machine grinds fresh beans on demand, which keeps quality high and waste low. The trade-off is that capacity is tied to the machine's brewing cycle, typically 25 to 40 seconds per cup, so a single machine serving 80 people at 9:00 AM creates a bottleneck unless you size correctly or add a second unit.
Semi-automatic equipment makes sense when you have a dedicated person running a coffee corner, a hospitality-focused reception, or a team that genuinely cares about espresso craft. For the average office pantry, it adds workflow complexity that most staff won't engage with consistently. We recommend it selectively, usually for clients who already have someone enthusiastic about running it.
Filter coffee is underrated for larger teams and meeting-heavy environments. A batch brewer produces 1.5 to 2 litres in under ten minutes, which means 15 to 20 cups ready simultaneously. It scales better than any espresso machine during peak moments, the cost per cup is the lowest of the three formats, and it requires minimal daily maintenance. The limitation is variety: filter coffee doesn't produce espresso-based drinks, so it works best alongside a fully automatic rather than as a standalone solution for a mixed team.
For most offices in the 10 to 100 range, the practical answer is a fully automatic machine as the anchor, with a batch brewer added once you pass roughly 40 to 50 staff or when you have regular meetings with external visitors.
How to calculate capacity for your team size
Headcount is a starting point, not a capacity specification. What actually matters is cups per working day and the shape of your demand curve.
A realistic consumption baseline for a Belgian office is 2.5 to 3.5 cups per person per day, though coffee-intensive teams (creative agencies, consulting offices, early-start logistics operations) run higher. Use 3 cups per person as a working assumption unless you have reason to adjust.
The calculation that matters:
- Take your headcount and multiply by 3 to get estimated daily cups.
- Identify your two peak windows: morning start (typically 8:00 to 9:30) and post-lunch (13:00 to 14:00).
- Assume 35 to 40 percent of daily consumption happens in the morning window.
- Divide that peak volume by the number of minutes in the window to get cups per minute required.
A team of 30 people needs roughly 90 cups per day. In a 90-minute morning window, that's about 32 cups, or roughly one cup every three minutes. A single mid-range fully automatic machine handles that comfortably. Scale to 80 people and you need 112 cups in that same window, which pushes a single machine to its limit. Two machines, or a machine plus a batch brewer, solve it cleanly.
Our practical tips for office managers go deeper on daily setup habits that keep machines running smoothly through peak hours without queues building up.
Buying versus leasing versus a service subscription
This is where most offices make their most expensive mistake: comparing machine purchase prices without accounting for the full cost of ownership.
Buying outright gives you asset ownership and no monthly commitment. It makes sense if you have capital budget, a reliable internal maintenance process, and a stable headcount. The risk is that repair costs, descaling, and bean logistics all fall on you. A machine that costs €1,800 upfront can cost another €600 to €900 over three years in consumables, filters, and service calls if you manage it yourself.
Leasing spreads the capital cost and typically includes a maintenance contract. Monthly costs are predictable, which matters for budget planning. The machine stays current because the supplier replaces it at end of lease. The trade-off is total spend over five years is higher than an outright purchase if the machine runs without problems.
A full-service subscription bundles machine, beans, maintenance, and often water filtration into a single monthly or per-cup cost. This model removes the most operational burden from your team. You're not managing bean stock, descaling schedules, or repair logistics. For offices where the facility manager wears multiple hats, this is usually the right answer. Our office coffee subscription starts at €0.22 per cup, which includes fresh-roasted specialty beans, machine support, and a dedicated account contact.
The variables that push cost up or down in any of these models:
- Bean quality (commodity blends versus specialty-grade single origins)
- Water filtration requirements (hard water areas need more frequent filter changes)
- Machine complexity (a super-automatic with milk system costs more to service than a basic espresso unit)
- Contract length (longer commitments typically lower the monthly rate)
- Number of machines and locations
What does a cup of office coffee actually cost?
The honest answer: between €0.18 and €0.65 per cup depending on machine type, bean quality, and service model.
Filter coffee sits at the low end. Beans for a filter setup typically run €12 to €18 per kilo for decent quality, and at 60 to 70 grams per litre, a 250ml cup costs around €0.20 to €0.25 in beans alone. Add machine amortisation and maintenance and you're at €0.22 to €0.35 per cup.
Fully automatic espresso with specialty beans lands between €0.30 and €0.50 per cup when you account for beans, machine cost, and service. Capsule systems often look cheaper on the machine side but cost more per cup in consumables, typically €0.35 to €0.65 depending on the capsule brand.
The metric that matters for budget conversations is annual coffee spend per employee, not machine price. At 3 cups per day, 220 working days, and €0.35 per cup, one employee generates €231 in annual coffee costs. For a team of 50, that's €11,550 per year. Knowing that number makes machine and service decisions much easier to justify to finance.
Understanding how grind size affects extraction and flavour also helps you get more from the beans you're already buying, which directly reduces cost per cup without changing your machine.
How to extend your machine's lifespan and reduce downtime
A professional coffee machine in an office environment needs weekly cleaning and monthly descaling as a minimum. Skipping this is the single most common cause of early machine failure and the most avoidable cost in office coffee management.
The practical checklist for a fully automatic machine:
- Daily: empty and rinse the drip tray and grounds container
- Weekly: run the machine's automatic cleaning cycle with cleaning tablets
- Monthly: check and replace the water filter if required
- Quarterly: book a professional service check if you're managing the machine yourself
Our guide on extending the lifespan of your automatic coffee machine covers this in full, including the maintenance schedule that keeps machines running for five or more years in high-use environments.
If you're on a service subscription, your supplier handles most of this. If you're not, build the maintenance calendar into your facility schedule the same week you install the machine, not after the first breakdown.
The machine type, team size, and cost-per-cup triangle is the only framework you need to make a confident decision. You now know how to calculate your actual daily demand, compare service models on total cost rather than sticker price, and avoid the maintenance gaps that cause most office coffee problems.

Frequently asked questions
What is the best coffee machine for a small office of 10 to 20 people?
A mid-range fully automatic machine is the best fit for most offices in this size range. It handles 30 to 60 cups per day without queuing, requires no barista skill, and produces consistent espresso-based drinks. Look for a machine with an integrated grinder and an automatic cleaning cycle. At this scale, a single unit is sufficient, and a service subscription that includes beans and maintenance keeps the operational burden minimal.
How many cups per day can a fully automatic office coffee machine produce?
Most mid-range fully automatic machines produce 80 to 150 cups per day under normal office conditions. High-capacity commercial units reach 200 or more. The limiting factor is the brewing cycle, typically 25 to 45 seconds per cup, plus the machine's bean hopper and water tank capacity. For teams above 50 people, plan for either a high-capacity unit or two machines to cover peak-hour demand without queues.
Is it better to buy or lease an office coffee machine?
Leasing wins when you want predictable monthly costs, included maintenance, and no capital outlay. Buying wins when you have budget, a stable team, and a reliable internal maintenance process. A full-service subscription is the best option when you want to remove coffee logistics entirely from your facility workload. Most Belgian offices with 20 or more staff benefit from a subscription model because the time saved on bean ordering, descaling, and repair coordination outweighs the slightly higher per-cup cost.
How do I calculate how many coffee machines my office needs?
Multiply your headcount by 3 to estimate daily cups. Identify your morning peak window (typically 90 minutes) and calculate how many cups need to be served in that window. One standard fully automatic machine handles roughly one cup every 30 to 40 seconds. If your peak demand exceeds that rate, add a second machine or supplement with a batch brewer for filter coffee. Teams above 50 people almost always benefit from at least two brewing points.
What does office coffee cost per cup, including machine and service?
The realistic range is €0.22 to €0.65 per cup depending on machine type, bean quality, and service model. Filter coffee with good-quality beans sits at the lower end, around €0.22 to €0.35. Fully automatic espresso with specialty beans and a service contract typically lands between €0.30 and €0.50. Capsule systems often cost more per cup in consumables despite lower machine prices. The most useful budget metric is annual spend per employee, which runs approximately €200 to €400 at typical office consumption rates.
Do office coffee machines need a direct water line connection?
Not necessarily. Most fully automatic office machines work with a built-in water tank, which is sufficient for teams up to 30 to 40 people. For larger teams or high-volume environments, a direct water line connection removes the need to refill the tank manually and reduces the risk of running dry during peak hours. Water line connection also makes it easier to integrate inline filtration, which protects the machine in hard-water areas and improves taste consistency.
