I use Sage 300 and have for about 7 years now. Sage is both easy and difficult, depending on what you need and who you are dealing with. Technical support is, in my opinion, top notch. Most of my support comes from my wonderful reseller, Kerr. But the part that comes straight from Sage is always on point. The downside tends to come from my AP dept when they deal with invoices. It has improved over the years, but was a challenge in the beginning. I still at times find myself confused by invoicing that should be the same year over year.
