Café ideas
Check a café idea before you open
A café is one of the most common dream businesses. It is also hard: rent and staff cost the same on quiet days, and each cup earns only a little. Here is how to check a café idea before you sign anything.

Four questions to answer first
- 1
Where do the customers come from?
Stand outside the place you like at different times: a weekday morning, lunch, a rainy afternoon, Saturday. Count the people walking past. Then think how many of them would stop.
- 2
Who is your regular?
Office workers on the way to work? Students? Parents after school? Each one wants different opening hours, prices and food.
- 3
Why you and not the café next door?
Better coffee is hard to show from the street. A clear difference is easier: a place to work, food for a diet, great baking, a kids’ corner, a view.

How many sales a day do you need?
Do the sum below with your own rough numbers. It is the most useful number in the whole plan.
The daily sum
Example with made-up numbers
- Monthly costs (rent, staff, electricity, insurance, card fees): €9,000
- Average purchase: €7. Coffee, milk, food and cups for it: €2.10.
- You keep €4.90 per purchase.
- €9,000 ÷ €4.90 = about 1,840 purchases a month.
- Open 26 days a month: about 71 purchases every day, just to cover costs.
Put in your real rent and wages. If the daily number looks too high, look at a smaller place, shorter hours or a higher average purchase.

Rules and paperwork to check
- Register the business and tell the tax office.
- Food rules: in most countries you must tell or register with the local food authority before you open. Ask them early: they can save you from a costly mistake in the kitchen plan.
- In Finland, staff who handle unpackaged food that spoils easily need a hygiene passport (hygieniaosaamistodistus).
- Alcohol, outdoor seating and music each need their own permits or licences in many places.
- Insurance for the business and for your staff.
These are things to check, not legal advice. Your local authority or an accountant can tell you exactly what applies to you.
Cheap ways to test a café idea
- Run a coffee stand at a market or an event for a weekend.
- Do a pop-up in a friend’s shop or a shared space.
- Sell your baking to an existing café first.
- Pre-sell a coffee card or subscription to people in the area.
- Ask 10 people who work or live near your chosen place where they get coffee now, and why.
Questions people ask
Can I start a café with little money?
Start smaller than a full café: a coffee cart, a market stall, a kiosk or a pop-up. You learn what sells and who comes back before you take on rent and staff.
How many customers a day does a café need?
It depends on your rent, wages and prices. Divide your monthly costs by what you keep from one purchase, then by your opening days. Our free check does this sum for you.
What is the biggest risk with a café?
Fixed costs. Rent and wages stay the same on quiet days. Check the location carefully and keep fixed costs low at the start.
