How many customers or orders do coffee shops get each day?
There is no dependable universal number. Owners' reports vary with location, hours, food, season, and how long the business has operated. Keep customers, transactions, and drinks separate: one person can buy several drinks, and a group can pay together. Compare like periods and similar businesses, then use your own observations or results. For a new shop, test where practical and plan for slower demand; another shop's count is not your forecast.
How can I estimate sales before opening?
Build the estimate from plausible transactions and the average order you expect to sell, separated by day and service period. Check those assumptions against local observation, comparable businesses, and a permitted test. Include quieter periods and a slower opening. The sales needed to cover your costs are a target to test, not evidence that customers will spend that much. Keep enough flexibility to change the plan when the evidence is weak.
Have consequential forecasts and borrowing assumptions reviewed by an appropriate financial professional.
How much coffee could we sell in an existing food business?
Start with your current sales and specific customer requests, then run a limited, consistent offer. Count coffee orders, repeat purchases, and what customers buy with them. Requests alone do not tell you how many cups will sell. Before buying more equipment, check whether the existing setup, staff practice, menu, or visibility is limiting the offer. Test the added work and money left from coffee alongside its effect on the rest of the business.
What share of people passing by will buy coffee?
Do not apply a fixed percentage to a traffic count. Pedestrians, vehicles, market visitors, and people already heading to another café are different opportunities. Check whether people see the offer, can stop, and encounter it when they want coffee. A permitted test can measure purchases under those conditions. Record the exposure count only if you can measure it sensibly; sales without a reliable denominator still teach you something.
