Is there some way using QB Online to set up graduated shipping rates to automatically show up? Example: 0-$250 Min 20.00 $251-399 8% 400-499 7% 500 and up 6% Thanks

Afaik, pricing rule feature is unavailable in QBO CA. Explore these 3rd party inventory management apps and integrate with your QBO.  You may specify shipping rates based on the value of your customer’s order. You can create different rates according to the minimum and maximum order price, and even offer free shipping for orders above a certain amount.
