How syncing works

SKUvio keeps your Shopify store and your Etsy shops in step. A few simple rules govern how everything fits together — once you know them, the app’s behaviour is easy to predict.

Shopify is the source of truth

Your Shopify catalogue is the master record. Product details, prices, and stock all originate in Shopify, and SKUvio pushes them out to Etsy. When something needs to change, change it in Shopify and let SKUvio carry it across.

Etsy orders are the one thing that flows the other way — they’re pulled into Shopify so all your orders live in one place.

SKUvio connects the same product across both stores using its SKU — the code you assign to a variant. When a Shopify variant and an Etsy listing share a SKU, SKUvio treats them as the same item and keeps them in sync.

This is why matching SKUs matter: if a product’s SKU is blank or different on each side, SKUvio can’t link them. Running Auto-Map SKUs on the Sync Controls page pairs everything up for you.

What syncs automatically

Once products are linked, these happen on their own, with no button to press:

  • Inventory, both ways — a sale on either store updates stock on the other in real time, so you’re never oversold.
  • Orders, into Shopify — new Etsy orders are imported automatically with buyer details, line items, and shipping.

What you trigger manually

Some actions stay in your hands, because they change your live listings:

  • Product export — creating an Etsy listing from a Shopify product happens when you click Export to Etsy.
  • Re-export — pushing updated content or prices to existing listings is a deliberate action, so a routine edit never surprises your storefront.

Only active items sync

SKUvio works with active products and active Etsy listings only. Draft or archived Shopify products are skipped, and inactive or expired Etsy listings are left alone — so nothing hidden gets synced by accident.
