About the PackOS Pack
PackOS solves inaccurate shipping rates at checkout by using bin-packing logic to select the correct box for every order. When box size is estimated wrong, merchants either overcharge customers and lose sales, or undercharge and lose margin. This app determines which box an order actually fits in, then queries live carrier rates from USPS, UPS, FedEx, and other carriers for that specific package. Merchants configure their box inventory once, set carrier preferences and shipping rules, and PackOS handles everything automatically at checkout.
