I love that it is very easy to use! It's super user friendly for both newbies as well experienced users alike!! The customer service team has been great at answering any questions we have had during our transition from other software companies (and even after!). They are always willing & ready with helpful tips/tricks of their own too. Nothing really - just be patient when setting up your account initially because there can sometimes take some time before you get all set in terms or features available through this programmme but once they're setup everything runs smoothly afterwards :) We've used several different programs over my career so far including many others within transportation logistics industry such DHL Worldwide Express etc., however nothing comes close compared tp how simple yet powerful goPetGoSoftware makes things seem like managing freight shipments using multiple carriers / shippers vs 1 carrier per shipment via traditional systems takes minutes rather than hours now!
