Basically, any small to medium size business can be done at home. But there is one particular kind of business that I really find suitable for home biz and that is food catering. Here in our place, there are at least 2 popular food catering services that are home based that are really doing good. These businesses are not even based in commercial places but inside residential homes, subdivisions. One good thing about food catering service is that people go to your place, place their orders there, and get it there themselves. If the food tastes great your catering service will spread by word of mouth and it's smooth sailing for you and your business, right in your home.
