DeliverBy Shipping Rates/Rules

DeliverBy Shipping Rates/Rules is an app that provides ecommerce merchants with the ability to show accurate delivery dates at checkout and set shipping rates by product group and schedule. Merchants can control the rates shoppers see based on various factors like cart weight, total, item count, or product quantity. The app calculates delivery dates from dispatch schedules, cutoff times, and fulfillment days, excluding weekends and holidays added by the user. Each product group can have its own rates and delivery estimates per shipping zone, allowing for customization and flexibility in shipping options.
