So my question is, is there a way on Shopify to bill or use a customers UPS account for shipping. For instance, we sometimes receive emails from customers for orders and we put it in the website manually for them. Well they have UPS accounts of their own and want us to bill their account. They provide us their account number. Is there a way to do this through Shopify or maybe a third party app?
You can integrate the Shopify store with the UPS carrier service, after configuring add UPS account with the following credentials.
UPS User ID
UPS Access Key
UPS Account Number
The Shopify UPS Shipping app Rates Shipping Labels Tracking the app will automatically enable all the UPS services that will be displayed at Shopify checkout.
