I like how flexible their system is, its easy to use when shipping items out from your home office. There are times it gets confusing if all products have not been entered into the database yet but once those issues get resolved everything works as expected. Shipping costs can become costly so having that information readily available helps in saving money overall. Its nice knowing there's someone else doing what we do best - tracking shipments! The ease in which I can use this program from my phone, anywhere! It is very user friendly with all aspects being easy accessibly via app store as well. Nothing really that i dislike about it but everything seems great so far except maybe there are more features available out their than what's listed here online? Have no complaints thus far though have only been using since April 2018.
