Focusing on Residential or Business... guess that depends on whether you have a storefront or not.
We don't have a storefront and don't need one as we focus mainly on business clients and turning them into managed service clients.
We don't advertise, not even on Yelp, on which we keep a 5* rating. So, other than word of mouth, current clients and Yelp, we don't venture into trying to obtain residential clients.
More time is spent on residential clients than on business clients. We like knowing that there is a specific amount of income coming in each month. We also use all the best tools in the industry (as far as we're concerned) with Kaseya, Connectwise,etc.
There is a saying "surround yourself with successful people and you will be successful". Those successful people surround themselves with successful people and when those business clients are your happy managed service clients, you now have foot in the door for additional good managed service clients.
The best thing you can do is find a niche in an industry and go with it, and shoot for obtaining a high percentage of the businesses in that industry.
One industry that can be a money maker is servicing restaurants... those using a POS system. You have to be on-call to get and keep their business because if their POS system is down or if they can't take credit cards for some reason, they're losing $$$. And you wouldn't believe your profit margin if you sell them on upgrading their software (not talking about Microsoft software).
Bars can also be profitable because of the credit card situation, but they may want you to take your fees out in trade - drinks (not a good idea), although taking your fees out in trade with a high-end steak house has it's benefits (if you're not a vegetarian).
