Calcurates: Accurate Shipping vs Shipping & Delivery ‑ ShipZipfor Shopify (2026)
Both Calcurates: Accurate Shipping and Shipping & Delivery - ShipZip are highly-rated Shopify apps designed to provide advanced shipping rate calculations and rules. However, they cater to slightly different needs. Calcurates positions itself as a comprehensive shipping solution focused on accuracy and leveraging carrier-calculated shipping for real-time rates from major carriers like UPS, USPS, and FedEx, along with advanced table rates and duty/tax calculations. It's aimed at merchants who need precision in shipping costs and handle international orders frequently. ShipZip, on the other hand, is more focused on customized shipping rules based on product attributes, customer location, and delivery date, making it ideal for businesses requiring granular control over shipping based on various order parameters. ShipZip emphasizes flexibility in defining shipping rates through multiple conditions tied to products (SKU, tags, vendors), zip codes, distance, and cart parameters. It also features unique functionalities like local delivery/store pickup with order delivery date settings and weekend delivery charges. The app offers functionality that appeals to local businesses like bakeries and flower shops by supporting time-slotted deliveries and store pickup. Calcurates offers duty & tax calculation making it more suited for international shipping while ShipZip focuses more on location based customizations. Both require Carrier Calculated Shipping (CCS).
