ShipWorks is an excellent addition to our company. It integrates effortlessly with our Magento 2 e-commerce site. It has streamlined our shipping process. No more typing customer information into shipping software. No more sending emails notifying customers that their product has shipped. No more typing in tracking information in those emails. No more shopping for shipping rates. Shipworks does it all. And we signed up with Stamps.com and our USPS Medium Flat Rate box cost changed from $13.60 to $12.45. Technical support is just as good as the software. They are patient and thorough at helping us with any need we have had.
