Works auto?

Hello I have a MAJOR urgent problem: I did a migration from Big Commerce to Woocommerce. All weight and size are entered in each per products – 400 of them. I would like to know if your plugin – once I enter the client Fedex credentials – the cost of Fedex shipping will show auto at checkout with just the weight and size info per product? My terror is that: do I need to create 400 shipping classes or does Fedex/your plugin will work with just the info entered per products – which are already there? Please say yes … I have a call with my client at 3pm eastern and we were supposed to go live right after that – the migration people just told me they cannot transfer the Fedex cost at checkout from Big Commerce to woocommerce so I am in a total panic here. Please tell me your plugin will do that without having to build 400 shipping classes. I could show you the site but you would need to change your host file because the DNS has not been changed yet Thank you so much 🙂 The page I need help with: [ log in to see the link] Hi, You don’t want to create shipping classes. Please save the FedEx credentials then it will take weight from the product & work fine.
