The Project


ATD Capitol Supply were moving their online store to Shopify. The had an existing freight calculation algorithm that needed to be ported across to the new store.


We implemented a custom Shopify Carrier Service, porting the existing freight shipping datasets and algorithm, integrating with the Shopify products and including an UPS lookup option for selected smaller products, along with a Shopify admin interface with rate lookup logs.
