How it sells itself

GemHub sync helps you push the media and product information from your existing GemHub Pro account to your Shopify online store. The process can be as simple as one click! You can choose to either push all your products from GemHub to Shopify, or just the ones in your GemHub collection.

SkuHarmony makes it easy to sell in both Shopify and Square, and have your inventory synchronized between both systems. When a product is sold in one, we remove it from the other so that you never oversell, and don't have to make these changes manually.

Key points
  • Push media from your GemHub account to Shopify
  • Fine tune the set of products to include in the push
  • Push to multiple online stores
  • Automatically synchronize your inventory to Square
  • Clone Products between Square and Shopify with a single click
  • Near Real-time adjustments

How Shoplist compares apps

Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Oct 14, 2026. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
