Shipping App Recommendations for specific situation

Shopify Apps

Topic summary

Main issue: Set flat shipping rates per box when multiple products ship together. Current setup with Boxify (box packing only) plus multiple Shopify shipping profiles causes combined rates at checkout, overcharging when items share a box.

Key constraint: Shopify combines shipping rates from different profiles; per Shopify help, there’s no workaround. “Shipping profiles” group products with specific rates; when a cart spans profiles, the rates are added.

Recommendations:

  • JsRates: Builds custom/complex shipping rules to match products to boxes and apply correct flat rates; support offered to set up rules.
  • ShipMagic: Claims straightforward configuration for this rate logic; live chat support available.

Alternative approach: Use a single shipping profile with weight-based ranges. Adjust product weights to represent box sizes to approximate shipping costs. This improves consistency but is not fully accurate.

Status: No resolution confirmed; discussion remains open.

Action items:

  • Engage JsRates support to design rules.
  • Try ShipMagic’s setup via live chat.
  • If app solutions don’t fit, consolidate to one profile and use weight-based estimates.

Hello @Terrawagen ,

If you create multiple shipping profiles, the shipping rates will be combined; there is no workaround for this.

You may create a single shipping profile and offer approximate shipping rates at checkout based on weight-based ranges.

You may adjust the weight of each product based on the size of the box. Again, this is a way to offer an approximate rate at checkout and not an accurate one.
