Businesses you can run over the internet: software and tools, marketing services, digital content, consulting and advisory work. Startup costs are usually lower than a physical unit — often a computer, a domain and a few subscriptions. Every entry states its costs, margins, step-by-step launch plan, risks, and a calculator you fill with your own figures.
A cheap start has a price of its own. A low barrier to entry means anyone can be doing the same thing next month. The real cost here is not the tooling but customer acquisition — months of writing, outreach and building a name before demand becomes steady. If you need revenue within weeks and dislike selling yourself, hands-on services will suit you better.
