Sure you can! 🙌

After you’ve connected your Carrier’s accounts, you can enter your customized Carrier’s Rates in a minute.

ShippyPro will automatically compare the shipping rates of your carriers and choose the best option for you. This way, you have all your Carrier’s Rates with your Carrier’s Options in one place and choosing the best option will be super quick.  
 
Also, you don't need to set them for every carrier, some of them (DHL Express, UPS, FedEx, MyDHL, TNT Italy, SkyNet, Amazon Shipping, Stuart, TNT Express and Aramex) automatically send your negotiated rates to ShippyPro after the connection.
