I like that it is easy to setup and configure for my needs. It has many features out of the box which makes set up quick and painless. The ability to create custom reports are also beneficial as they provide access to information when needed without having to go into each function manually. There isn't much that I dislike about fitrix besides the occasional lag time (or lack thereof) while using some functions such as creating invoices/purchase orders or generating quotes etc. If you need an enterprise level ERP package then this is perfect! As far as customization goes we were able to build functionality quickly due to its modular components. We had been missing advanced salesforce fields such as lead conversion tracking within our product. This allowed us to track how well our marketing efforts were converting leads into actual customers, giving insight into what methods work best for us moving forward.
