This is the heavier end of the catalogue: full-time businesses that usually need premises, staff and real capital β a unit, equipment, stock, the first payroll. Every entry states its startup cost, its margins, a step-by-step launch plan, the risks, and a calculator you fill with your own figures instead of ours.
Here is what similar lists rarely admit. The biggest line item is often not the machinery or the rent, but the months when fixed costs are already running and revenue is not. If you do not have a reserve for half a year of operation, and you would rather avoid employees, permits and opening hours, you will be happier in online business or hands-on services.

Unlock the full databaseUsually the one where you already have a trade, contacts or industry experience β those shorten the time to first revenue more than any trend does. Compare each idea's startup cost against its margin and payback period in the catalogue, and choose on your own numbers rather than on popularity.
It ranges by orders of magnitude: some ideas need a van and tools, others a full fit-out. Each entry breaks the startup cost into items. Add a reserve covering fixed costs until revenue arrives β that reserve is usually the largest and most underestimated part of the budget.
Mostly not, in this category. Opening hours, staff and deadline-bound contracts sit badly next to fixed employment. If you are keeping your job for now, ideas from online business or hands-on services let you schedule the work around it far more realistically.
