Online business ideas

Run the idea through the idea check, which looks at search demand, the competitors already selling and the complaints their customers leave. Complaints about existing sellers show what buyers want and are not getting. Before you build anything, try to get a few people to pay or pre-order.

Profit depends on your price, the cost to win each customer and how much of your own time each sale takes. Choose a service if you have a skill people pay for and little cash to start; choose a product if you can fund the upfront work and want income that does not grow with your hours. Test your own numbers in the unit economics calculator before you pick.

Yes, if you sell a skill you already have, since your main cost is your time and a few tools. Ideas that hold inventory or need paid ads to get the first sales cost more to start. A market page lists start costs from open sources with links, so you can compare before you choose.

Rules depend on your state, county and city, and on what you sell, so check with your state's business registration office and your local government before you take payment. Some regulated services, such as tax preparation or health advice, have their own rules. Our guide on how to start a business walks through registration, taxes and permits step by step.

Run each idea through the business idea validator and compare the scores out of 100. Look at the weakest of the nine axes for each one, since a single low axis such as thin demand or poor unit economics can sink an idea with a good total. Start with the idea whose weak points you can fix.

List the sellers who show up when you search for what you plan to offer, then note their prices, what they include and what their customers complain about. Our market analysis guide shows how to turn that into a short gap list. If you cannot find any gap, pick a narrower audience or a different idea.
