Yikes! So the complaints having been steadily increasing related to websites like Software Advice. Maybe it seemed obvious to me but, unless you have worked in the point of sale 'world', you may not be aware that websites like Software Advice exist to make money by selling your information as a "lead" to multiple companies. Given the number of complaints that I have received about Software Advice over the last few weeks, you may want to consider other resources.
I realize that even trying to figure out what you need in a point of sale system can be time consuming, but that is why most states have small business development centers to help you out for free or low cost. You can also find impartial point of sale reviews and information on websites like CNET.
