Thinking about buying

some accounts for my biz,can anybody tell me what the pros and cons are?
how do you know they are good steady paying customers,how do you make
sure they even are legit,not that I am not trusting,I have never bought accounts before, any input

Are you talking about buying work?

yes I am looking into window rounds and pool service rounds to stimulate some growth,and pool service as an add on

My friend was looking at buying a pool route, and what the guy selling it did was have the buyer go on his route with him for a week or 2, this allowed for a smooth transition and proved that the customers were legit.
you current schedule would have to allow for this of course.
