When we had our own business years ago, we didn’t need call center services because of our size. I can see how large businesses might need these services, though.  We did need insurance for our business, advertising, and other services.   There were so many things to see about plus our regular business hours that it was common for us to put in 60+ hour work weeks.  Looking back, it would have been nice to have been able to afford some other services to help.
