CSR is a versatile app designed to simplify the process of setting up custom shipping rates for your online store. With CSR, you can create detailed shipping rate tables using Excel and effortlessly upload them via CSV files. This enables your customers to explore and select from a variety of shipping methods tailored to their needs. Please note, the app is exclusively available for merchants on Shopify's Advanced and Plus plans, as it leverages the Shopify Carrier Service API, which isn't supported on the Starter and Basic plans. The app not only offers flexibility but also saves you time with its intuitive, fast setup process. Whether you're editing shipping rates manually or via CSV, CSR provides a seamless experience to manage and optimize your shipping options. If you're looking to enhance your online store's shipping capabilities, CSR could be the ideal solution.
