SellerApex vs Shopify Marketplace Connect
The default, Shopify-owned way to push a Shopify catalog to Amazon, eBay, Walmart and Etsy.
Honest verdict
Start with Marketplace Connect if your catalog is small and every SKU already has a GTIN. Switch to SellerApex the moment listings start coming back Inactive — that repair work is exactly what SellerApex automates.
