How to test the financial viability of a business idea

1. Is there a customer willing to pay?

Define the customer, the problem you are solving and the evidence that people will pay for your solution. Conversations, pilot sales and competitor research are generally more useful than relying only on personal enthusiasm.

2. What will it cost to begin?

List once-off start-up costs such as equipment, setup, stock, deposits, licences and technology. Then separately identify ongoing costs including rent, salaries, subscriptions, marketing, insurance and administration. Keep a contingency allowance for unexpected expenses.

3. Does the pricing model make financial sense?

Estimate the revenue you can generate per customer, the direct cost of providing the product or service and the gross margin remaining. Understand how many sales are needed to cover fixed operating costs. An attractive price to customers is not sufficient if the margin cannot support the business.

4. When will money come in and go out?

A feasible income statement is only part of the picture. Consider customer payment terms, inventory or supplier deposits, VAT and other tax timing where relevant, and the working capital necessary to operate while the business becomes established.

5. What happens if expectations are wrong?

Build realistic base, optimistic and downside scenarios. Ask what happens if sales are lower than expected, costs rise or customers pay later than planned. The point is not to predict the future perfectly, but to understand which assumptions matter most.

What a useful feasibility assessment delivers

A feasibility assessment should make key assumptions visible, outline estimated capital needs, identify important risks and support a reasoned decision about whether to proceed, refine the concept or test it further. It cannot guarantee that a business will succeed.
