Shopify overview
What is the Transdirect Shopify app?
Section titled “What is the Transdirect Shopify app?”The Transdirect Shopify app brings carrier-calculated shipping rates directly into your Shopify checkout. Your customers see live quotes from multiple couriers — including road, air, and express services — and choose the option that suits them best.
Behind the scenes, the app sends each customer’s delivery details and cart contents to Transdirect, retrieves real-time pricing from our courier network, and presents the results as shipping options at checkout.
