Etsy and eBay bring you different buyers. Etsy shoppers tend to come looking for handmade, vintage and one-of-a-kind finds. eBay shoppers often arrive with a specific item in mind and a price to beat. List the same products on both, and you reach both crowds without making anything new.
The catch is that the two marketplaces don’t talk to each other. Each keeps its own stock count, and neither knows when the other makes a sale.
Here’s how that plays out. A ceramic mug sells on Etsy at 9 p.m. Your eBay listing still shows it in stock, so someone buys it there before breakfast. Now you’re cancelling an order for a mug you don’t have, and eBay counts a cancellation for being out of stock as a transaction defect against your seller standards.
Checking both shops by hand works for a while. It stops working once you have dozens of listings, a few variations and sales landing overnight. That’s the job an Etsy eBay integration app takes over.
This guide compares six of them on price, sync speed and what they actually keep in step, so you can pick the kind that fits the way you sell.
What is an Etsy eBay integration app?
An Etsy eBay integration app connects your Etsy shop and eBay store so a sale on one updates the other. Some apps sync stock counts both ways for products you restock. Others crosslist one-off items and delist them everywhere once they sell. Pick the type that matches what you sell.
The two types solve different problems:
- Inventory sync tools keep one stock count across both channels. Sell one of 42 shirts on Etsy, and eBay drops to 41 too. QuickSync, LitCommerce, and Sellbrite work this way.
- Crosslisters copy a listing from one marketplace to another, then remove it everywhere after it sells. They’re built for resellers with single items. Vendoo and Nifty work this way.
If you sell the same products again and again, you want the first type. If every item is one of a kind, the second type is usually enough.
What to look for in an Etsy eBay integration
These are the details that decide whether an app works for your shop:
Two-way stock sync. A sale on either channel should lower the count on the other. One-way sync only protects one side.
Sync speed. Check how often the app reads each channel. A 15-minute gap is fine for slow sellers. For fast-moving stock with low counts, shorter is safer.
SKU matching. Most apps match products by SKU. According to QuickSync’s Etsy eBay integration page, Etsy caps SKUs at 32 characters and eBay at 50, so keep yours to 32 or fewer. Our guide on what a SKU is covers how to set them up.
Variations. Etsy allows two option types per listing, like size and colour. A product with three options needs to drop one or be split before it can sync.
How you’re charged. Apps charge per order, per listing or per shop. Count your monthly orders and active listings before you compare prices.

The 6 best Etsy eBay integration apps, reviewed
Each Etsy eBay integration app below connects Etsy and eBay in some way. The first one is ours, so we’ve been specific about what it doesn’t do.
1. QuickSync: best for keeping one stock count across Etsy and eBay
QuickSync is a multichannel selling tool. You connect your Etsy shop and eBay store once, and it keeps stock, listings, prices and orders in sync automatically across both, so you run two marketplaces like one shop.
Here’s what it handles across Etsy and eBay:
- Inventory sync, both ways. A sale on either marketplace lowers the count on the other. QuickSync reads Etsy stock every two minutes and eBay every couple of minutes, according to its Etsy eBay page.
- Listing and product sync. Connecting imports both catalogues. QuickSync can then create listings on Etsy or eBay from your main store, as drafts where supported, so you can review them before they go live. On Pro, it keeps the title, description, photos, options, and price in sync with your master store, as described on the product syncing page.
- Order sync. Every sale from both shops lands in one place, already matched to the right product, according to the order syncing page. Tracking numbers go back to eBay and to Etsy, where Etsy grants shipping access.
- Price rules. On Ultra, you can set a different price on eBay than on Etsy, for example, to cover eBay’s fees.
- SKU matching and checks. Products match by SKU, and any that don’t match are handed back to you. QuickSync also flags Etsy’s limits, like two option types and 32-character SKUs, before anything publishes.
- Room to grow. The same account connects Shopify, Amazon, TikTok Shop, WooCommerce, Squarespace, Square, Clover, and more, up to eight shops.
Pricing: Lite costs $19 a month for two shops and up to 1,000 items, with stock sync. Pro costs $29 a month for up to 2,500 items and adds product and order sync. Ultra, at $69, adds price rules, so eBay can carry a different price from Etsy. Orders are unlimited on every plan. See the QuickSync pricing page.
Watch out for: QuickSync doesn’t connect to Poshmark, Mercari, or Depop. Etsy only accepts tracking updates where it grants shipping access for your location, so some Etsy orders still need tracking added by hand. Price rules start on Ultra.
Good fit if: you sell the same products on Etsy and eBay and restock them.
2. Sellbrite: best free starting point for low order volumes
Sellbrite is a multichannel listing and inventory tool. It connects Etsy, eBay, Amazon, Walmart, Shopify and more, with unlimited channels on every plan.
It enables sellers to create and manage listings across marketplaces, synchronize inventory quantities, and centralize order management. Its automated inventory updates help reduce stock discrepancies and minimize the risk of overselling across multiple channels.
- Inventory and price sync. Paid plans sync both every 15 minutes. The free plan syncs inventory every 2 hours.
- Listing tools. You can create and manage listings for each channel from one place.
Pricing: According to Sellbrite’s pricing page, Free covers up to 30 orders a month. Pro 100 costs $29 a month for 100 orders, Pro 500 costs $79 and Pro 2K costs $179, all billed yearly. The page offers 14 days of unlimited access with no card.
Watch out for: Plans are capped by monthly orders, so a busy month can push you up a tier.
Good fit if: you have a small shop and want to test syncing for free.
3. LitCommerce: best for listing on many marketplaces
LitCommerce is a multichannel listing tool. It lists products on Etsy, eBay, TikTok Shop, Walmart, Amazon and others from one place.
It allows sellers to create and manage product listings from a centralized dashboard, synchronize inventory and pricing across connected marketplaces, and streamline order management.
- Listing tools. AI listing optimization for Etsy and eBay, plus scheduled publishing.
- Inventory, price and order sync. All three run every 15 minutes.
Pricing: Its pricing page shows the Multichannel Listing plan from $29 a month, starting at 1,000 listings and three channels, with unlimited orders. There’s a 7-day free trial with full features.
Watch out for: If you sell fast-moving items with low stock, check that a 15-minute gap is short enough for you.
Good fit if: you want to push listings to many marketplaces quickly.
4. 3Dsellers: best for eBay-first sellers who want listing tools
3Dsellers is an eBay-focused selling tool. It can connect Etsy, but only on its top plan. Most of its features are built around running an eBay store well, from listing design to buyer messages.
Higher plans add inventory and order management on top. If Etsy is only a small part of your sales, it lets you keep eBay at the centre of your business.
- eBay listing tools. Listing templates, bulk editing and image hosting.
- Other channels. Shopify, Amazon, Etsy, and Walmart connect on Professional only.
- Inventory and orders. Growth and up add an inventory manager, an orders manager and bundles and kits.
- Bulk updates. Growth and up can import and update listings from a CSV file, on a schedule if you like.
Pricing: 3Dsellers’ pricing page lists Essential at $19 a month and Growth at $39.90. Professional, the only plan that connects Etsy, starts at $79 a month ($59 billed yearly) for 2,000 listings. There’s a 7-day free trial with no card.
Watch out for: You pay $79 or more to connect Etsy at all. Its pricing page doesn’t say how stock syncs between eBay and Etsy, so confirm that before you switch.
Good fit if: eBay is your main channel and Etsy is a side shop.
5. Vendoo: best low-cost crosslister for resellers
Vendoo is a crosslister for resellers. You create a listing once and post it to eBay, Etsy, Poshmark, Mercari and other marketplaces. It suits resellers who list many one-off items, like thrift and vintage finds.
When an item sells on one marketplace, Vendoo removes it from the others. It also has a mobile app, so you can list from your phone.
- Crosslisting. One listing goes out to several marketplaces.
- Sale detection and auto-delisting. Covers eBay, Etsy, Poshmark, Mercari, Depop and Whatnot.
- Listing templates and import. Every plan includes templates, importing existing listings, delist and relist, and a mobile app.
- AI and bulk edits. Growth adds AI listing enhancement and bulk actions on up to 240 listings at once.
Pricing: Vendoo’s pricing page lists Starter at $14.99 a month, Growth at $29.99 and Pro at $59.99, with unlimited items. The 14-day free trial needs a payment method.
Watch out for: It’s built around delisting single items. If you restock the same products, a tool that syncs stock counts suits you better. See our Vendoo alternatives guide for more.
Good fit if: you resell one-of-a-kind items across many marketplaces
6. Nifty: best for resellers who also want automation
Nifty is a reseller tool that combines crosslisting with marketplace automation. It’s aimed at resellers who spend hours on daily tasks like relisting and sending offers.
You can buy crosslisting and automation on their own or as a bundle. The automation runs in the background, so your computer doesn’t need to stay on.
- Crosslisting. Includes sale detection and auto-delisting.
- Automation. Automation plans run without your device open.
- Bulk actions. Relist, send offers and edit listings in bulk.
- AI listings. AI-powered listing generation, plus drafts and scheduled posts.

Watch out for: Its pricing page doesn’t say which marketplaces auto-delisting covers. Check Etsy and eBay support before you subscribe.
Good fit if: you crosslist resale items and want routine tasks automated.
Also worth a look: If you resell on Poshmark, Mercari and Grailed too, read our List Perfectly review and our roundup of crosslisting apps.
Which Etsy eBay integration app fits your business?
Start with what you sell. If you restock the same products on Etsy and eBay, choose an inventory sync tool like QuickSync. If you also want listing tools for many marketplaces, look at LitCommerce or Sellbrite. If every item is one of a kind, a crosslister like Vendoo or Nifty is enough.
| Your situation | What to use |
|---|---|
| Same products on Etsy and eBay, restocked often | QuickSync |
| Etsy, eBay and a Shopify store or POS | QuickSync |
| Listing new products on many marketplaces | LitCommerce or Sellbrite |
| Fewer than 30 orders a month, testing the waters | Sellbrite Free |
| eBay is your main channel and you want templates | 3Dsellers Professional |
| One-of-a-kind resale items | Vendoo or Nifty |
Here’s what two-way sync looks like in practice:
How to connect Etsy and eBay
Here’s how to sync Etsy and eBay inventory with QuickSync. Most of the work is cleaning up your SKUs first.
- Clean up your SKUs. Give each product the same SKU on Etsy and eBay, 32 characters or fewer. Fix any SKU used twice in the same Etsy shop.
- Check your variations. Etsy allows two option types. Split or simplify any product with three.
- Connect both channels. Log in to Etsy and eBay and approve QuickSync on each one’s own screen.
- Pick your source store. Choose the channel whose stock counts are right today. QuickSync uses it as the starting point.
- Review the matches. QuickSync matches products by SKU and lists any it couldn’t pair, so you can fix them.
- Test on a few products. Make a test sale on one channel and check the count drops on the other before you turn on the rest.

Final thoughts
Every app here connects Etsy and eBay, but they do different jobs. Crosslisters copy listings and delist sold items. Inventory sync tools keep one stock count, which is what matters once you sell the same products more than once.
If you’re a reseller with single items, Vendoo or Nifty will save you time. If you list across many marketplaces, LitCommerce or Sellbrite cover more ground. If your Etsy shop and eBay store sell the same restocked products, two-way sync is the part to get right first, because it’s the part that costs you orders when it breaks.
QuickSync keeps one count across Etsy, eBay and 11 other platforms, with unlimited orders on every plan. You can test it on a handful of products before you move everything over. Not sure Etsy and eBay are both worth it? Our eBay vs Etsy comparison covers fees and audiences.
