How to test a business idea before spending money on it

The expensive mistakes are rarely bad ideas. They are usually decent ideas a person bought into, before anyone checked to see if buyers even exist and how much they are paying.

Buying a pallet of stock for a product nobody was searching for. Paying for a logo and packaging before making a single sale. Committing to a niche because it sounded like a good idea. All classic ways people lose money, and almost all avoidable with about an hour of checking first. (And if you are wondering whether your niche is too crowded, we wrote about how to tell if a side hustle is saturated separately.)

Here is a pre flight list that costs nothing and saves you the classic mistake.

The pre flight checklist

1. Find five people already doing it, and write down what they charge. If you cannot find anyone doing it, not always good news, it often means nobody has found a way to make money there. Five competitors means demand exists.
2. Read twenty reviews of those five, and note every repeated complaint. This is the gold. Complaints are unmet demand, and the same complaint showing up across several sellers is a gap you could fill.
3. Work out what it costs you to deliver one unit or one hour, honestly, including your time. Most people skip the 'including your time' and wonder later why they are working for £2 an hour.
4. Ask whether your version answers a complaint from step two. If it does, you have got a real angle. If it does not, you are competing on price.
5. Decide the smallest possible first test, and cap what you will spend on it. Before you spend anything, know your limit.

Keep the first test small

One batch. One listing. One weekend. The point is not to build the business yet. The point is to find out if a stranger will pay, at a price that works, without you having to persuade them into it.

What good evidence actually is

• A sale to someone you do not know (friends buying to be nice proves nothing).
• A repeat buyer, or a referral.
• A question about availability rather than price. When people ask 'is this in stock' rather than 'can you do it cheaper,' you have found something.

If the first test goes well, spend more. If it does not, you have lost a weekend instead of a month of stock.

The step most people skip

Steps one and two, the ones about who is already doing it and what buyers complain about, are exactly the ones people cut because they take effort. They are also the ones that save you the most money.

That is the bit we built SideSus to do for you. Describe your idea in a sentence and it checks the live web for who is already selling it, what they charge, what people complain about, and where the gaps are. It is the 'before you spend money' check, done in about a minute, for free.
