The easy to use interface, the ability to customize to your needs and the wide range of add-on modules that can be used. The support is also excellent. We have been using Addon Software for over 10 years now and it has never disappoint. I wouldn't say that there is anything that I dislike, it's been a good product to use and we're continuously using it. The support is great, they are always there to help. The ERP capabilities are really good and the reports are also great. It has helped us with our accounting.
