How to sync inventory between Shopify and Etsy so you keep one stock count

Does Shopify integrate with Etsy?

Not with a built-in switch. You add an app from the Shopify App Store, or you use a separate inventory system that talks to both shops. One thing has changed that older articles miss: Shopify's own Marketplace Connect app (formerly Codisto), which links to Amazon, eBay, Walmart and Target Plus, no longer accepts new Etsy connections. Shopify's help pages say that if you already sell on Etsy through it you can keep using it. A new seller needs a different tool.

Three ways to keep stock in step

1. By hand or CSV. You update both shops yourself, or export a spreadsheet and import it. It costs nothing and works for a few products. Craftybase, an inventory app for makers, suggests this is only sensible for sellers with roughly 10 to 15 products and slow sales. After that, mistakes pile up.
2. A sync app. The app reads one shop and pushes stock to the other. Cheap and quick to set up. Its weakness is that it only knows about listings, not your materials or batches.
3. One stock record that feeds both. A separate inventory system holds the true count and pushes it to Shopify and Etsy. Best when you make things in batches or sell on a third channel soon.

The CedCommerce listing describes inventory syncing on its entry plan as Shopify to Etsy, so read whether stock flows both ways before you rely on it for sales that start on Etsy. Sellbrite's listing says it adjusts and syncs inventory to avoid overselling. For a wider system view, see inventory management systems.

Step by step: set it up so it does not break

1. Turn on "Track quantity" in Shopify for every product. It is a product setting. When it is off, Shopify accepts orders without limit and the sync has no number to read. Craftybase notes that some themes and setup flows leave it off for new listings. Count what you really have, enter it, then turn tracking on.
2. Give every product and variant a SKU. A SKU is a unique product code. Sync apps match products between shops by SKU. Etsy does not require one, so many sellers have none. A Shopify listing with SKU CAND-LAV-8 and an Etsy listing with no SKU are invisible to each other.
3. Make the codes identical. Same characters, same capitals. Etsy suggests short SKUs of 4 to 8 characters and says to avoid symbols such as commas or slashes, which can confuse programs like Excel. "8oz", "8 oz" and "8OZ" look like three things to a matching tool.
4. Match the variant structure. Shopify builds a separate stock line for each combination, such as Lavender 4oz. Etsy lets you vary a listing on up to 3 attributes, such as size, color and style, and you can set a separate SKU, price and quantity for up to 400 option combinations per listing (Etsy Help Center, as of November 2026). Past that, options share the listing's details. Craftybase also warns that complex nested variations can make Etsy reject an update. If Shopify has three options and Etsy has two, stock lands in the wrong slot. Keep both shops parallel.
5. Pick one master. Shopify, or your inventory system. The other shop follows. Never edit stock by hand in the follower shop.
6. Check two settings that clash. Craftybase describes both. If Shopify is set to continue selling when out of stock (for pre-orders) while Etsy has a hard quantity cap, the two disagree after a sale. And Etsy auto-renews a listing by default, so a renewed listing after a last sale can look like fresh stock.
7. Test with 5 products. Change stock on one side. Place a small test order on each side. Check the count afterward on both. Then roll out in batches.

Etsy's developer documentation confirms why SKUs and variants matter: an Etsy listing's inventory is a list of products, each with a SKU and offerings that carry a quantity and a price. A sync tool writes those fields, so messy data in means messy stock out.

Handmade and variant-heavy products

Handmade sellers have a few extra problems.

• Batches. You make 24 candles, not one. A listing-to-listing sync app can only copy numbers. It cannot tell you that you ran out of wax. If you make things in batches, a system that tracks materials and finished goods is worth a look.
• Made to order. If an item is made after it sells, give it a high fixed quantity on both shops and manage capacity by hand. That avoids false sell-outs.
• One-offs. A one-of-a-kind piece should have a quantity of 1 on both shops. This is where delay hurts most, so a faster sync interval matters more here than the app price.
• Bundles. Craftybase advises mapping the individual items rather than a bundle you fulfill by picking singles.

Shopify, Etsy and Printful

Printful is a print-on-demand service: it prints and ships items only after a customer orders. Its Etsy integration page says products and orders sync automatically once connected. Because nothing is held in stock, you have no stock count to protect. You mainly need your products and orders to land in the right place. If you mix Printful items with items you make yourself, keep the made-in-house items on the SKU system above and leave the print-on-demand items outside it.

When one stock record is the better fix

A sync app works well with finished goods and two shops. Switch to one stock record feeding both shops when any of these is true:

• You make products in batches or from raw materials.
• You add a third channel, such as Amazon or TikTok Shop.
• You carry bundles or the same stock under different listing names.
• You have had an oversell that cost you a review or a refund.

How I'd approach this

Start free or cheap. Fix SKUs and Shopify's Track quantity first, in a spreadsheet, before you install anything. Then try Sellbrite's free plan or CedCommerce's $9 Beginner plan on a few products. Whichever app you test, run a real test order before you trust it.

If you sell more than a few dozen items, make things in batches, or want a third channel, I would stop adding apps and set up one stock record. That can be a maker-focused system such as Craftybase or, if your rules are unusual, a small custom setup that holds the count, applies a safety buffer per shop, and alerts you when a number looks wrong. I build those for small brands. If you want to talk it through, book a quick call with me.
