FullWell review for ShipperHQ: Shipping & Checkout

I've used ShipperHQ at multiple companies because of their ability to implement complex shipping logic (both on Shopify and Magento). It's crucial to show our customer the estimated delivery day at checkout, which is dynamically displayed based on MY business's shipping rules (same-day shipping cut off, blackout days, day of the week they order, etc) coupled with the carrier's real-time API. Their support team is very accessible and thorough. They are also open to adding features and functionality to their roadmap with a good use case! I could NOT do ecommerce without ShipperHQ.
