If you sell on Etsy and take card payments at markets, craft fairs or a shop counter with Square, a Square Etsy integration keeps one stock count across both. Otherwise, the item you sold at Saturday’s market is still for sale on Etsy, and someone buys it on Sunday.
Etsy has a free Square integration built in also, and for many sellers it’s enough. But it only works in one direction. This guide explains what Etsy’s free sync does, when you need a Square Etsy integration app instead, and how the four best Square Etsy integration apps that connect them compare on price and sync. Prices come from each vendor’s own pages and Square’s App Marketplace, checked in November 2026.
Short answer: if Etsy is your only online shop and you only add or edit items on Etsy, use Etsy’s free Square sync. If you also add items in Square, sell from more than one Square location, or want stock to sync both ways, you need an app. QuickSync starts at $19 a month with unlimited orders, Trunk at $35 a month for up to 100 orders, LitCommerce at $29 a month and Nembol at $39 a month.
How Etsy’s Free Square Sync Works (And What It Doesn’t Sync)
Etsy lets you connect a Square account from your Shop Manager at no cost. It’s available to sellers in the US, UK, Canada and Australia, but not in US territories such as Puerto Rico and Guam.
Once connected, Etsy copies your listings to the Square Point of Sale app. When you sell one of those items in person, Etsy lowers the stock on the listing. That’s the whole job.
The catch is in Etsy’s own help page: “Syncing from Square to Etsy is not supported at this time. If you add or edit your items on Square, these changes won’t be reflected on Etsy.” Listings and edits only flow from Etsy to Square. The only thing Square sends back is the in-person sale.
When Etsy’s Free Sync is Enough, and When It isn’t
It’s enough if Etsy is your main catalog, you sell in person from one Square location, and you only ever add or edit items on Etsy. You need an app if any of these apply:
- You add new stock in Square, such as market-only pieces or counter items, and want it on Etsy too.
- You change prices or quantities in Square and expect Etsy to follow.
- You sell from more than one Square location.
- Your shop sells digital items only, or has products with more than 250 variations. Etsy’s sync fails on both.
- You also sell on Shopify, eBay, TikTok Shop or Amazon, and want one count everywhere.
Quick Overview of the Best Square Etsy Integration Apps
Search Square’s App Marketplace for “Etsy” and three apps come up: LitCommerce, QuickSync and Trunk. Nembol connects Square too, but isn’t listed there.
| Option | Starts at | You pay by | Sync direction | Square App Marketplace | Free trial |
|---|---|---|---|---|---|
| Etsy’s built-in sync | Free | Nothing; Square processing applies | Etsy to Square only | Set up in Etsy | Not needed |
| QuickSync | $19/mo for two shops | Items (variations); orders unlimited | Both ways | 5.0 (77 reviews) | 14 days, no card |
| Trunk | $35/mo for up to 100 orders | Orders a month | Both ways | 5.0 (90 reviews) | 14 days |
| LitCommerce | $29/mo | Listings and channels | Both ways | 4.9 (34 reviews) | 7 days |
| Nembol | $39/mo for 200 products | Products; orders unlimited | Both ways | Not listed | 14 days |
How Each Square Etsy Integration App Charges
For Square sellers, this matters more than the starting price. A market stall or shop counter can ring up a lot of small sales, and some apps count every one.
- QuickSync counts items, meaning each variation a buyer can pick. A variation sold on several channels still counts once, and orders are unlimited on every plan.
- Trunk counts orders a month. Its pricing FAQ tells a coffee shop “with lots of drink orders” to get in touch about fairer pricing, which suggests sales rung up in Square count toward your tier. If you take a lot of in-person payments, ask Trunk before you start.
- LitCommerce counts listings and connected channels, with unlimited orders.
- Nembol counts products. Variations and orders are unlimited.
1. QuickSync
Best for: market and shop sellers who want Square and Etsy to sync both ways without paying more as sales grow.
QuickSync connects Square to Etsy and matches products and variants by SKU. Sell a bag through Square and Etsy’s stock drops; sell one on Etsy and Square updates. You choose which products sync and which Square locations count, and you can connect more than one Square account. It also connects Shopify, eBay, TikTok Shop, Amazon, WooCommerce and more, up to eight shops.
- Price: Lite $19/mo for two shops and up to 1,000 items, with stock sync. Pro, at $29/mo for 2,500 items, adds product syncing (edit prices, images and descriptions in one store) and order syncing. Ultra is $69/mo for 10,000 items. Orders are unlimited on every plan, and yearly billing saves 10%. 14-day free trial, no card.
- Sync: QuickSync checks Etsy stock every 2 minutes and Etsy orders every 5.
- Watch for: Etsy SKUs can be up to 32 characters, against 80 in Square, so keep yours short. If two Etsy listings share a SKU, QuickSync keeps sync off for both until you separate them.
2. Trunk
Best for: sellers with bundles, kits or materials-based stock and fewer than about 100 orders a month.
Trunk builds one inventory from all your channels and links listings that share a SKU. It describes its sync as real-time. Its Pro plan adds bundling and kitting, so a gift set lowers the stock of each item inside it, plus syncing for duplicate SKUs.
- Price: Essential from $35/mo for up to 100 orders, then $45 for 101 to 200 orders and $59 for 201 to 400. Pro from $39/mo for up to 100 orders, then $59 and $79. Unlimited channels and listings. 14-day free trial.
- Rating: 5.0 from 90 reviews on Square’s App Marketplace.
- Watch for: Trunk reviews your order count before each bill and moves you up or down a tier automatically. A busy market month can cost more.
3. LitCommerce
Best for: Square sellers who want to list on Etsy plus several other marketplaces.
LitCommerce imports your Square catalog and lists it on Etsy, Amazon, eBay, TikTok Shop, Temu and more, with bulk editing, templates and an AI description writer. When you sell in person through Square, stock updates on your connected marketplaces, and you can process channel orders from your Square store.
- Price: from $29/mo for 1,000 listings, 3 channels and unlimited orders. Its Square listing offers 20% off yearly plans. 7-day free trial.
- Sync: inventory, price and order import every 15 minutes, according to its pricing page.
- Watch for: a 15-minute gap is long for one-of-a-kind pieces. A shopper can buy on Etsy what you sold at the stall a few minutes earlier.
4. Nembol
Best for: crosslisting a small catalog to many channels, including social and Google Shopping feeds.
Nembol added Square in 2026. It imports your Square catalog, publishes it to Etsy and other channels, and updates stock whether an item sells through Square POS, Square Online or a marketplace. You can edit in Square and import the changes, or edit in Nembol and push them to Square.
- Price: $39/mo for 200 products, $49 for 2,000, $79 for 5,000 and $129 for 15,000. Orders and variations are unlimited, and paying yearly saves 25%. 14-day free trial.
- Watch for: it isn’t on Square’s App Marketplace, and its Square integration is new. Transferring orders for fulfillment starts on the $49 plan.
Square vs. Etsy: Comparing Selling Fees
Selling in person through a synced Square account skips Etsy’s 6.5% transaction fee and Etsy’s payment processing. You pay Square’s card rate instead, plus Etsy’s $0.20 auto-renewal on the listing. Here’s a $40 item with no shipping or tax:
| How it sold | Fees | You keep |
|---|---|---|
| In person, synced item, Square Free (2.6% + 15¢) | $1.19 Square + $0.20 Etsy renewal = $1.39 | $38.61 |
| Online on Etsy (6.5% + 3% + 25¢ + 20¢) | $2.60 + $1.45 + $0.20 = $4.25 | $35.75 |
Sync before market day for another reason too. If you sell something through Square that isn’t synced to an Etsy listing, Etsy charges $0.20 per sale, shown on your bill as a “Square manual” fee, and your Etsy stock doesn’t change. More on Etsy’s charges in our Etsy fees guide and Square’s in our Square fees guide.
Etsy Square Sync Not Working? Common Causes
- “Sync has unfortunately failed. Try Again.” Etsy shows this if your shop has only digital listings, or if a product has more than the 250 variations Square’s system allows.
- Changes made in Square don’t show on Etsy. That’s by design. Etsy’s sync never sends Square edits to Etsy, so edit on Etsy, or use an app that syncs both ways.
- Sales aren’t lowering Etsy stock. Check that you’re selling from the Square location linked to your shop (Square Sales Channel page, then Choose your location), and that the item was synced rather than entered by hand.
- New listings are missing in Square. Run Sync your Listings again after adding listings, and allow about a minute per 300 listings.
Whichever route you take, give every item a SKU before you connect anything. Our guide to what a SKU is shows how, and Etsy inventory management covers keeping counts right.
Which Square Etsy Integration Should You Choose?
- Etsy is your only catalog and you sell from one Square location: Etsy’s free sync.

- You sell bundles or kits and stay under about 100 orders a month: Trunk Pro, from $39/mo.

- You have a small catalog and want it on social and shopping feeds too: Nembol, from $39/mo.
Before a big market or holiday weekend, test whichever you choose: sell one item through Square and check Etsy’s count drops, then the other way round. Getting ready for the holiday rush? See our Black Friday tips for Etsy sellers.
