Columbia Business School Gear review for Calcurates: Accurate Shipping

Calcurates is our preferred shipping rate calculator for both Shopify and Magento 2. We've tried all the different solutions for charging duties and taxes at checkout, and Calcurates is the winner by far. They even help us calculate the shipping costs of packages coming from multiple warehouses, using multiple carriers, all in one order. Their pricing is a lot better than their competitors as well.
