I like that it's very user friendly for new users as well! It also has an option to have your own custom fields which can be helpful if you need more than what they offer in their system out of box options. The only thing i dislike about this program from other programs we use at work are not available with shipping solutions so there may or could possibly some issues using them together but overall great product!! We've been able to create our invoices quicker then before because its much easier now knowing how many items were shipped per invoice instead having each item listed separately by hand when creating previous versions.
