Scalable business ideas
Where revenue isn't capped by your calendar.
A business is scalable when serving the next customer costs much less than the last. That rules out most pure hourly work. It favours software, digital products, content and productized services.
Making a service more scalable
- Productize: fixed scope, fixed price.
- Templatize and automate the repeat parts.
- Add a self-serve product (course, template) for clients who can't afford you.

How to choose between these ideas
Score each idea 1–5 on four questions and start the one with the highest total:
- Can you get paid in 30 days? Services usually beat products here.
- Do you already have the skill? Learning and selling at once doubles the risk.
- Do you know where buyers gather? A community, marketplace, local street or your old industry.
- Could it run on 5–10 hours a week? Most people start alongside a job.
Then validate before spending money: see how to test a business idea.
