Selling on TikTok Shop With Shopify: Setup and Tips

To sell on TikTok Shop with Shopify, install the TikTok app from the Shopify App Store, connect your TikTok accounts, and sync your products. Orders and inventory can then be managed from your Shopify admin.

This guide covers the setup and the fashion-specific work that matters most, such as sizing and photos. If you haven't set up the basics yet, start with adding virtual try-on to Shopify alongside your product pages.

What does the TikTok app for Shopify do?

The TikTok app is made by TikTok Inc. and connects your Shopify store to TikTok advertising and TikTok Shop. According to its Shopify App Store listing (checked November 2026), it can:

• Create TikTok ads from your own images or videos.
• Add the TikTok Pixel, which tracks ad performance.
• Sync TikTok Shop to Shopify so you can show products through video and LIVE.
• Let you manage TikTok Shop orders and inventory from the Shopify admin.

The listing says the app is free to install, though additional charges may apply. Ad spend is billed directly to your TikTok ad account.

The listing also says TikTok is only compatible with certain stores. Check the listing for the current requirements, and confirm TikTok Shop is open to sellers in your country before you plan around it.

How do you set up TikTok Shop with Shopify?

Follow these steps in order:

1. Check eligibility. Read the app listing and TikTok's seller information for your country.
2. Install the app. Add the TikTok app from the Shopify App Store and approve its access.
3. Connect your accounts. Log in to your TikTok business and ad accounts when the app asks.
4. Sync your catalog. Choose which products to send to TikTok. Start with a small group of best sellers.
5. Review each listing. Check titles, prices, sizes and images after the sync.
6. Place a test order. Walk through the flow as a customer would.

Keep your variant names the same in Shopify and on TikTok. A mismatch in sizes is a common cause of wrong orders.

What should fashion stores prepare first?

Clothing buyers on a video feed decide quickly. Prepare these before you sync:

• Clear size information. Show body measurements for each size, not only labels like S or M.
• Photos on different bodies. Include at least one image that shows how the garment drapes.
• Short fit notes. Say whether an item runs small, large or true to size.
• Consistent stock counts. Sync inventory so you don't sell what you no longer have.

If you sell made-to-order or custom pieces, read selling custom-size clothing on Shopify first. Custom sizing needs extra steps at checkout.

How do you make TikTok content that sells clothes?

You don't need a studio. Phone video of real people wearing the item works well for apparel.

• Show the garment moving: walking, sitting and turning.
• Say the model's height and the size worn in the video or caption.
• Show the fabric up close, then the full outfit.
• Reply to comments with fit answers, then reuse those answers in your product description.

Treat every repeated question in comments as a gap in your product page.

How does sizing affect TikTok orders?

Shoppers who arrive from a video often buy on impulse and can't ask anyone for help. A wrong size leads to a return, and returns cost you shipping and time.

You can lower that risk on your own store page. ZeDaq.ai adds a "Find my size" scan, where the shopper uploads one photo and types their height, and sees a size from your size chart. The Shopify app is on the ZeDaq.ai listing. Note that this runs on your Shopify product pages. It does not appear inside TikTok itself.

What are common setup mistakes?

• Syncing the whole catalog at once, then spending days fixing errors.
• Leaving out size charts, which leads to guesswork.
• Ignoring order sync, so TikTok orders are handled by hand.
• Forgetting that ad spend is a separate bill from TikTok.

How does TikTok fit with your other channels?

Treat TikTok as one door into the same store. Keep prices, sizes and stock the same everywhere, so a customer never sees a different answer on each channel.

Many brands also sell through Instagram. The steps are similar, and the guide to selling on Instagram with Shopify covers them. Whichever channel you add, test one product end to end before you add the rest.

After launch, review three things each week: which videos drive visits, which products get questions about fit, and which orders come back. Use those answers to improve your product pages.
