I like that it's easy to use for both shippers as well receivers of shipments with multiple carriers (we have over 20). The only thing we dislike about this program so far was how much time you spend inputting information into each carrier/carrier line item - especially if there are many items per day or week! It can be frustrating at times because sometimes certain fields will just not show up when they're supposed too but other than those little quirks everything has been seamless thusfar.- Shipping costs- Tracking numbers from different companies(allowing us access via phone)- Receiving info once shipped out.
