Inevitably a service based business is the least expensive business to launch, because the primary asset is you. You can immediately start a car cleaning business, consulting business, or a programming business – if you do all the work.
Yes, there will be supplies, materials or equipment that you need. But you can limit them, rent them, or start with used ones. There is always a way to get started with little cost when you start a service based business.Just be aware of the one big trap.
To start the business, you will need to do the work. To grow the business, you will need others to do the work. Easily said, not easily done.
The day will come that you have done the work for so long, that it will be hard (or impossible) to get others to do it. If you can’t make the transition, your company won’t be able to either.
