Creating a rule that does not use Boxify to calculate shipping costs.

Shopify Discussion

Topic summary

A merchant uses Boxify for accurate USPS cubic shipping calculations on their Shopify store, as Shopify’s native calculations don’t support this method. They also sync Amazon and eBay orders (which have free shipping) into Shopify via Salestio for consolidated fulfillment.

The Problem:

  • Boxify calculates shipping for all orders, including the synced marketplace orders
  • This creates unnecessary transactions that count against Boxify’s monthly quota
  • Salestio claims it doesn’t request shipping calculations; Boxify says Shopify triggers them automatically

Desired Solution:
The merchant wants to exclude Salestio orders from Boxify calculations, potentially using the “Amazon” or “eBay” tags that Salestio applies to these orders.

Status: The question remains unanswered—seeking advice on whether conditional rules can prevent Boxify from processing tagged orders, or if alternative tools exist for this use case.

Hello everyone,

I operate a storefront that receives orders, and I rely on Boxify to accurately calculate the shipping costs for my customers, as the built-in Shopify calculations are not very reliable and does not support cubic shipping. Since I offer hundreds of products with varying sizes, using USPS volume dimensions provides the most accurate and cost-effective shipping solution for them.

I also receive orders for specific items that I sell on Amazon and eBay with free shipping, and I use Salestio to sync these orders with Shopify, so everything is consolidated in one place. This helps streamline my fulfillment process using Pirate Ship and for account purposes.

My issue is that when orders come from Salestio to Shopify, Boxify still calculates the shipping cost. Since Boxify charges a monthly fee based on the number of transactions, this results in unnecessary transactions, which consume my quota.

Salestio claims that it isn’t requesting a shipping calculation, while Boxify states that Shopify is automatically triggering the calculation for all orders.

Is there a way to instruct Shopify to skip the shipping calculation by Boxify for orders that come from Salestio? Salestio tags these orders with an “Amazon” or “eBay” label, so could I create a rule based on this?

If this isn’t possible, are there alternative tools that would work better for this scenario?

Thank you in advance for any assistance.
