There's less risk in starting a commercial cleaning franchise, but you have to pay franchise fees and forgo some of your autonomy. On the other hand, if you launch your own business, you have no support from a parent company, which can be valuable when you're first starting out.
The choice comes down to how much risk you're willing to take on. See our article, "Should I Go Solo or Start a Cleaning Franchise?" for more details about the costs and benefits of each option.
