I find Control to be complete overkill for all but the largest sign shops. The software is convoluted, complicated, and a royal pain in the partookas to use. There's no reason you couldn't use Quickbooks (and maybe something like Estimate and time clock software) to take care of all your POS needs, unless of course you're a large sign shop that can afford the tech support and programming necessary to get that monstrosity to behave as expected. But I'm not bitter
