Initial costs vary enormously from franchise to franchise. With Vend'or you are actually buying the machines and the initial £20,000 gives you 10 placed machines to get started with.

But as franchise manager John Mellor explains, "With SSL, you only buy from an existing franchisee as all territories are covered. This means the amount you pay depends on the stock and the size of territory. It could be £20,000 and £40,000 respectively."

However all the franchises have very low overheads. You just need somewhere to deal with any admin that comes up and somewhere to store the products. Obviously bottled water takes up more room than condoms but neither has a short shelf life or is particularly perishable so a garage or outhouse is sufficient if you don't have room in the house.

And you don't have to have a flash expensive van either. In the case of SSL some kind of van is needed but with Vend'or and Drinkmaster providing you have a car at your disposal there's no extra cost here either. Just petrol is the main cost - and paying out for the stock - but you will learn the best ways to cut these by planning your routes and ordering at the right time.
