If you've ever watched a product take off on TikTok only to sell out on Shopify before you could catch up, you already know why a TikTok Shop Shopify integration matters. Shopify's built-in TikTok channel gets the lights on, but it wasn't built to keep pace once inventory, pricing, and orders start moving fast. A dedicated TikTok Shop connector is what keeps your Shopify catalog and your live TikTok Shop listings actually in agreement, in real time, so a viral moment turns into sales instead of a logistics headache.

We ran 10 of the top TikTok Shop integration apps from the Shopify App Store through the same test: sync speed, category mapping accuracy, order fulfillment reliability, and how honest the pricing actually is. TikTok Shop Integration — SPL takes the #1 spot, and it earns it by being built around large catalogs and advanced feed control: think advanced product feed management, real-time inventory syncing, bulk editing, multi-location support, and error diagnostics that flag listing issues before TikTok rejects them. That makes it a natural fit for merchants with large catalogs, complex inventory setups, or any brand that wants more granular control over how products actually appear on TikTok Shop. Layer in real-time product and inventory sync, order and return management, customizable rules, and bulk product mapping, and it's easy to see why SPL is our pick as the best app to sync Shopify products to TikTok Shop, a genuinely robust catalog sync solution that holds up well for medium to large inventories, backed by Built for Shopify status and a 4.9-star average across 800+ verified reviews.

Why TikTok Shop Shopify Integration Matters

• Shoppers on TikTok actually buy. Compared with most social apps, TikTok's audience converts what it sees in-feed into action, whether that's a search or an outright purchase, so a properly synced storefront pays off the effort of setting it up.
• Manual catalog uploads don't hold up. TikTok's Seller Center will take a one-time catalog upload, but nothing updates on its own after that, not prices, not stock, not new SKUs. Someone has to keep repeating the work by hand unless a connector is doing it for you.
• Selling out of stock hurts your standing. When Shopify and TikTok fall out of sync and you sell something you don't have, that means cancellations, refunds, and a seller score that drags down your future reach.
• Category rules are tighter than they seem. TikTok requires specific attributes per category. A listing that's perfectly fine on Shopify can still get bounced on TikTok if it lands in the wrong category or is missing something the category demands.
• Orders need to land back in Shopify. Shopify, not TikTok Shop, has to stay your source of truth for shipping, tracking, and returns, so orders placed on TikTok need to flow into Shopify on their own, not get manually exported and re-keyed.
• Selling across regions adds another layer. Running the US, the UK, or several EU markets means your Shopify locations need to line up cleanly with the right TikTok warehouse per market, or your stock counts will drift.

In practice, picking the right TikTok Shop connector comes down to four questions: is the sync genuinely real-time, does it handle category mapping without constant rejections, does pricing scale reasonably as your order volume grows, and how quickly does support respond when something breaks? The ten apps below answer those questions differently, so the right choice really depends on the size of your catalog and how many TikTok Shops or marketplaces you're managing.

How We Tested (Fair and Transparent)

Ecomzier works with merchants and agencies on Shopify apps and TikTok Shop integrations day in and day out, including our own Ecomzier Tiktok Shop Connector. What follows draws on that direct experience plus each app's current Shopify App Store listing, pricing page, and public reviews as of July 2026. Here's the criteria we applied to every app on the list:

• How the sync actually flows. Does it move products, inventory, and orders in both directions (Shopify ↔ TikTok), or is it a one-way push?
• Category mapping approach. Is it AI-driven, manual, or template-based? This one factor accounts for most listing rejections, so it matters more than it looks.
• How reliably fulfillment works. Do orders make it back into Shopify consistently, and do merchant reviews show a pattern of dropped or delayed syncs?
• How honest the pricing is. Is there a real free plan, what do the order and product caps look like at each tier, and does cost scale sensibly with volume or catalog size?
• What the App Store listing shows. Star rating, review count, and Built for Shopify status, pulled straight from the live listing.
• How support holds up. We looked for repeated patterns across named reviews rather than one glowing or one furious outlier.

A quick note on transparency: Ecomzier Tiktok Shop Connector, sitting at #2, happens to be our own app, and we'd rather flag that upfront than have you find out later. Its spot on this list comes from the same scoring above, not from favoritism, and if anything it's the least proven entry here, still building up a review history. SPL takes the #1 slot purely because the numbers back it up, no other app comes close on review volume or consistency. A handful of other connectors beat everything else at something specific, AfterShip's creator marketplace, DPL's flat monthly fee, CedCommerce's account managers, M2E's reach across other marketplaces, Ownbase's field-level sync control, and we point that out directly wherever it applies.

How to Connect Shopify Products to TikTok Shop (2026 Guide)

Before you install a third-party connector, it's worth knowing that Shopify ships with its own TikTok sales channel, and it handles the very first link between your store and TikTok Shop, catalog, inventory, fulfillment, and orders, right from the Shopify admin you already use. For a lot of merchants, this is the quickest route to a live TikTok Shop, and several of the specialist apps further down actually build on top of this native channel rather than replacing it.

What Your Store Needs First

• A verifiable address set up in Shopify's Locations settings
• A store based in a country TikTok Shop currently supports (see below)
• An active online store, along with a TikTok for Business account, which you can also set up mid-onboarding from inside the TikTok app
• A published return policy page live on your storefront (details just below)

Your Return Policy (and a 2026 EU Update)

TikTok Shop won't approve onboarding without a visible return policy. Inside Shopify, that lives under Settings > Policies, where you set your return window (14, 30, 90 days, unlimited, or a custom period), decide who covers return shipping, and optionally add a restocking fee. Self-serve returns and cancellations also need to be switched on, so customers can submit a request directly instead of just reading your policy text.

Prohibited Products, Country by Country

Every product has to clear TikTok's prohibited-products policy for the exact country you're selling into, and the rules aren't the same everywhere. Something cleared for TikTok Shop US isn't automatically fine for the UK or Germany, so check the policy for each market before your first bulk sync:

Setting It Up, Step by Step

1. From your Shopify admin, head to Settings > Sales channels, then click Shopify App Store.
2. Search TikTok, open the sales channel listing, and click Add channel.
3. On the Set up TikTok Shop screen, click Connect under the TikTok Shop section.
4. Sign in with an existing TikTok for Business account, or register fresh using your phone number, email, and a password.
5. Read through the TikTok Shop Merchant Terms of Service, then click Connect to authorize the link back to Shopify.
6. Under Shop information, click Verify to confirm your shop details and upload whatever documentation TikTok asks for.
7. Click Finish setup. From here, your catalog, inventory, and orders can start syncing between Shopify and TikTok Shop.

The 10 Best TikTok Shop Integration Apps for Shopify in 2026

1. TikTok Shop Integration — SPL

Best Overall · Built for Shopify · Free to install · 4.9★ (800+ reviews)

TikTok Shop Integration — SPL holds Built for Shopify status and a 4.9 out of 5 average across 800+ reviews. It leads this list because it handles the entire sync loop, products, inventory, orders, fulfillment, and returns, across as many TikTok Shops as you connect, all from a single Shopify admin, with the core connection left free of a paywall.

Features

• Dual-direction sync: updates flow both Shopify to TikTok and TikTok back to Shopify for inventory.
• AI-powered category auto-mapping: matches Shopify products to the correct TikTok Shop category and required attributes automatically.
• Multi-shop connections: sync several TikTok Shops from one Shopify admin, useful for multi-region sellers.
• Power Editor: customize how a product listing appears on TikTok directly inside the app, without leaving Shopify.
• Multi-currency and multi-language: supports 11 languages including English, Japanese, French, Italian, Arabic, German, Portuguese (Brazil), Chinese (Simplified), Spanish, Thai, and Vietnamese.

Pros and Cons

Pros	Cons
Built for Shopify certified with 800+ reviews at 4.9 stars (96% five-star)	Full pricing tiers are only shown after installing, not upfront on the listing

Free to install. Plans start at $9.99/month for higher order and product volumes, with full pricing details shown after installation.

Final Verdict

If you're just getting started with TikTok Shop, make SPL the first thing you install rather than something you land on after a pricier app underdelivers. Two-way sync, category mapping, and multi-shop support all ship in the free tier, and no other app here has a bigger or steadier review history behind it.

2. Ecomzier Tiktok Shop Connector

Best New Free Entrant · Built by Ecomzier · Free · 5.0★ 

Ecomzier Tiktok Shop Connector is our own app, built and supported in-house by our Shopify Plus engineering team. It went live on the App Store on May 14, 2026, so it's the youngest app in this roundup by a wide margin, only a few weeks in the wild as of writing. Functionally, it matches our top-ranked pick step for step, real-time two-way sync, AI-driven category mapping, multi-currency and multi-language support, and a built-in Power Editor, and it's what we point our own Shopify Plus clients toward when they want a free connector with our team on the other end of support.

Features

• Connect and sync multiple TikTok Shops with your Shopify store
• Dual sync: Shopify to TikTok and TikTok to Shopify inventory updates
• AI-powered category matching for product listings
• Multi-currency and multi-language support for global selling
• Power Editor for adjusting TikTok listing details inside the app

Pros and Cons

Pros	Cons
Completely free with no paid tier currently listed	Only 7 reviews and a few weeks of App Store history at time of writing
Perfect 5.0 rating so far, with reviewers praising fast support response	Not yet Built for Shopify-certified
Backed directly by Ecomzier's Shopify Plus support team	No long-term track record yet for high-volume or multi-shop reliability

Pricing

Free to install, with no paid plan currently listed.

Final Verdict

Run this next to SPL if direct access to Ecomzier's support team matters more to you than a long track record. It's genuinely free and fully featured, just weigh that against the short review history while you figure out what fits your setup long term.

3. CedCommerce TikTok Shop

Best for Managed, Full-Service Support · Free to install · 4.8★ (234 reviews)

CedCommerce TikTok Shop centers its whole design on managing listings, orders, inventory, and returns under one dedicated account manager instead of a rotating ticket queue. One reviewer described going from 20 to 30 orders a month to over 20,000, all with the same account manager guiding the growth.

Features

• Automated category assignment, bulk editing, and product upload
• Auto order sync and fulfillment, including sample orders
• Pricing and inventory rules to prevent over- and under-selling
• Image optimization, bundle product order handling, and meta-attributes
• Dedicated technical account managers on paid plans

Pros and Cons

Pros	Cons
Dedicated account managers are a genuine differentiator for merchants who want hands-on setup help	Free plan is limited to 1 region (US or UK) with no real-time sync
Pricing and inventory rules actively prevent overselling, not just alert after the fact	Real-time sync and refund/cancellation sync require the $19/month Basic plan or higher
Long track record with 234 reviews since April 2024	Growth plan at $89/month is the priciest tier on this list for full multi-region EU selling

Pricing

Free forever plan (unlimited product imports, 1 region, basic support). Basic is $19/month (100 orders) or $49/month (500 orders, bulk mapping templates). Growth is $89/month (1,000 orders, AI product optimizer, multi-region EU selling).

Final Verdict

Choose this if you'd rather have someone managing the setup alongside you than figure it out solo. Plan on the Basic tier at minimum, real-time sync doesn't come with the free plan.

4. AfterShip for TikTok Shop

Best for Scaling with a Creator Marketplace · Built for Shopify · 4.7★ (295 reviews)

Of everything on this list, AfterShip for TikTok Shop has been around the longest, it launched back in November 2020 as part of AfterShip's Feed lineup. Sync is just the starting point here: a Catalog AI cleans up listings automatically before they publish, and there's a creator marketplace of 5 million-plus creators (200,000+ with verified TikTok Shop GMV) for brands chasing affiliate-driven growth alongside the sync itself.

Features

• Inventory, orders, and fulfillment sync automatically from Shopify
• Oversell protection and fulfillment holds prevent lost sales
• Catalog AI optimizes every listing before it publishes to TikTok Shop
• Returns management through Loop, Happy Returns, Amazon MCF, or Narvar
• Access to 5M+ creators, including 200K+ with verified GMV, for collaborations

Pros and Cons

Pros	Cons
Longest track record on this list, launched in 2020, from an established logistics brand	The free plan only works on development stores, not a live store
The creator marketplace is unique among apps on this list for driving TikTok Shop sales, not just syncing them	Per-order overage fees ($0.20 each) apply once you exceed your plan's order allowance
Returns integrations with major providers (Loop, Happy Returns, Narvar) are unmatched here	Recent reviews show some inconsistency in support response times

Pricing

Free (development stores only). Basic is $9/month for 10 orders, plus $0.20 per extra order. Scale is $59/month for 300 orders, plus $0.20 per extra order, and unlocks Catalog AI auto-listing and up to 20 sales channel connections.

Final Verdict

Pick this if growth, not just syncing, is the goal, particularly if creator partnerships are part of your plan. Move to Scale once your orders climb, the per-order fees on Basic add up fast.

5. DPL – TikTok Shop Integration

Best Flat-Rate, Unlimited-Order Plan · Built for Shopify · 4.8★ (73 reviews)

Digital Product Labs takes DPL's pricing in a different direction than everything else here: a single flat fee, unlimited orders, no tiered brackets tied to order count. It's also upfront about mapping Shopify locations to TikTok Shop warehouses, a step that catches out multi-location sellers on apps that don't spell it out clearly.

Features

• Two-way product import, export, and inventory sync
• Smart Upload Profiles for bulk product uploads with custom pricing and titles
• Syncs Shopify locations directly to TikTok Shop warehouses
• Automated order management and fulfillment
• 24/7 support via live chat, tickets, and calls

Pros and Cons

Pros	Cons
Single flat plan includes unlimited orders, no per-order overage fees	No free plan, only a 7-day trial before billing starts
Explicit warehouse-to-location mapping helps multi-location sellers avoid stock mismatches	Smaller review base (73) than SPL, CedCommerce, or QuickSync
Reviewers name specific support staff praised for fast, patient help

Pricing

Early Adopter Plan is $14.99/month flat: publish and import up to 50,000 products, manage unlimited monthly orders, with a 7-day free trial.

Final Verdict

Take a close look at this one if your orders swing unpredictably or are growing quickly, a flat fee means you never have to reshuffle tiers whenever sales spike. Just plan for the cost from day one, there's no free tier to fall back on.

6. QuickSync for TikTok Shop

Best for Multi-Location Inventory Sync · 4.7★ (336 reviews)

With 336 reviews, QuickSync for TikTok Shop has the second-deepest track record here, and multi-location inventory sync is where it clearly shines for sellers juggling several Shopify warehouses. That said, a pattern shows up in recent reviews worth flagging: the sync sometimes stops without warning the merchant, a real risk that should factor into your decision alongside its strengths.

Features

• Real-time inventory syncing between Shopify and TikTok Shop
• Product syncing that instantly reflects changes across stores
• Order syncing that keeps all orders directly inside Shopify
• Multi-location support across all connected inventory locations
• Bulk import and export of products with full details

Pros and Cons

Pros	Cons
Multi-location sync is a genuine strength for warehouse-heavy sellers	Recurring merchant reports of sync silently stopping without notification
Tiered plans scale from small catalogs (1K items) up to large ones (20K items)	No free plan, starts at $19/month
Named support reps frequently praised for fast, knowledgeable help	Not Built for Shopify-certified

Pricing

Lite is $19/month (up to 1,000 items). Pro is $29/month (up to 2,500 items, adds product and order syncing). Ultra is $69/month (up to 10,000 items, syncs video and notes). Ultra+ is $99/month (up to 20,000 items). All plans include a 14-day free trial.

Final Verdict

Decent for catalogs spread across multiple locations, but check sync status by hand during your trial, given how often merchants have reported it going quiet without notice.

7. M2E Multichannel Connect

Best for Selling TikTok Shop Alongside Other Marketplaces · Built for Shopify · 4.8★ (29 reviews)

M2E Multichannel Connect casts a much wider net than anything else on this list: instead of syncing TikTok Shop alone, it links Shopify to TikTok Shop, Amazon, eBay, Temu, Walmart US, and over 450 Mirakl-based marketplaces, plus Shein, Kaufland, and OTTO, all from one dashboard. It makes the most sense if TikTok Shop is one piece of a bigger expansion plan rather than your only channel.

Features

• Create listings and link inventory across TikTok Shop, Amazon, eBay, Temu, Walmart, and Mirakl marketplaces
• Automatic real-time price and quantity updates pushed to every connected channel
• Orders sync across all locations to prevent overselling on any single channel
• Bulk listing creation and bulk order management
• Parts fitment data for eBay Motors and GPSR compliance tools for EU sellers

Pros and Cons

Pros	Cons
Broadest channel coverage on this list, one app instead of stacking a separate connector per marketplace	The free tier isn't a hard cap, it auto-bills $39 once you cross $1,000/month in order sales
Genuinely usable free starter tier (1,000 listings, 1 seller account) before any billing kicks in	Smallest review base on this list (29), including at least one recent unanswered complaint about Walmart sync
Reviewers point to hands-on support, including screen-recorded walkthroughs for troubleshooting	TikTok-specific depth (category mapping, Power Editor-style tools) isn't the main focus the way it is for SPL or CedCommerce

Pricing

Starter is free to install (1 seller account, 1,000 listings, up to $1,000/month in order sales, then $39 kicks in). Starter 5K is $39/month (adds Shein, Kaufland, OTTO; 2 seller accounts; 5,000 listings; up to $5,000/month in sales). Starter 20K is $79/month or $816/year (adds Mirakl's 450+ marketplaces; 3 seller accounts; 20,000 listings; up to $20,000/month in sales). Every paid tier includes a 30-day free trial, plus $6 per additional $1,000 in sales beyond your plan's allowance.

Final Verdict

Worth serious consideration if TikTok Shop sits alongside Amazon, eBay, or Walmart in a broader marketplace strategy. If TikTok Shop is your only channel today, a TikTok-only specialist like SPL or CedCommerce will likely give you deeper TikTok-specific tooling for a similar or lower cost.

8. Ownbase: Sync to TikTok Shop

Best for Field-Level Sync Control · 4.7 (23 reviews)

Ownbase: Sync to TikTok Shop has been listed since 2022, and one thing sets it apart: you pick exactly which attributes make the trip to TikTok Shop, images, descriptions, status, variants, inventory, prices, chosen individually instead of an all-or-nothing feed. The other consistent thread in its reviews is quick, hands-on support.

Features

• Two-way product and inventory sync between Shopify and TikTok Shop
• Field-level control over which attributes sync (images, description, status, variants, inventory, price)
• Unlimited TikTok Shop order syncing into Shopify
• One-click publishing of new products to TikTok Shop
• Easy linking of products that already exist on TikTok Shop

Pros and Cons

Pros	Cons
Granular, field-by-field control over what syncs is unmatched on this list	No free plan, just a 30-day trial before billing starts
Unlimited order syncing on both paid tiers	Smaller review base (23) than most apps on this list
Reviewers repeatedly praise fast, hands-on support	Not Built for Shopify-certified

Pricing

Basic is $15/month (up to 500 products, unlimited orders). Advanced is $30/month (up to 5,000 products, unlimited orders). Both plans include a 30-day free trial.

Final Verdict

If a previous connector has ever overwritten a field you never wanted touched, this is the fix. The catch is a lower catalog ceiling and no free plan, so it fits better under 5,000 SKUs than above it.

9. SKU IQ for TikTok Shop or POS

Best for Stores Also Running a POS · 3.9★ (113 reviews)

SKU IQ for TikTok Shop or POS solves a narrower problem than the rest of this list: keeping Shopify, a physical POS like Clover, Square, or Lightspeed Retail, and TikTok Shop all synced together, not just Shopify and TikTok. A US-based support team and a free tier for existing POS customers are genuine perks, but its 3.9-star average trails everything else here, and reviewers repeatedly mention inventory drifting when connections hiccup.

Features

• Real-time product, order, and inventory sync across TikTok Shop and POS systems
• Single dashboard for sales performance, recent orders, and sync events
• Fulfill TikTok Shop orders directly from Shopify
• Works with Clover, Square, and Lightspeed Retail alongside TikTok Shop
• US-based support team plus an onboarding consultation

Pros and Cons

Pros	Cons
One of the only apps here that also syncs a physical POS, not just TikTok Shop	Lowest average rating on this list (3.9), with a notable share of 1-star reviews
Free add-on tier for merchants already using SKU IQ on their POS	Standalone plans start higher than most apps here, from $45/month
US-based support team with a free onboarding consultation	Recurring reviewer complaints about inventory drift during connection issues

Pricing

Free as an add-on if you already run SKU IQ on your POS. Standalone: Basic is $45/month (100 orders, 1 location). Plus is $89/month (500 orders, up to 2 locations). Growth is $159/month (1,500 orders, up to 5 locations). All standalone plans include a 14-day free trial.

Final Verdict

Only reach for this if a physical POS is actually part of your operation, that's the one job here nothing else on the list can do. If TikTok Shop is your only additional channel, you'll get more mileage from a connector built around TikTok specifically.

10. ShopSync for TikTok Shop

Best Free Bulk-Sync Option for Larger Catalogs · Free · 3.3★ (12 reviews)

Datech built ShopSync to move large catalogs quickly, at no cost: one click bulk syncs 1,000-plus products, order tracking covers up to 1,000 orders in real time, and custom pricing and inventory rules pair with category mapping templates for bulk updates. It'll also handle several Shopify and TikTok Shop accounts from one dashboard. That said, its review count is the thinnest on this list and sentiment is mixed, with a few merchants noting slow support during time-sensitive issues, so start with a smaller product batch before going all in.

Features

• Bulk sync of 1,000+ products between Shopify and TikTok Shop in one click
• Real-time order tracking and shipping status for up to 1,000 orders
• Custom pricing and inventory rules to prevent overselling
• Category mapping templates for batch product updates
• Manage multiple Shopify and TikTok Shop accounts from one dashboard

Pros and Cons

Pros	Cons
Completely free with genuine bulk-sync capacity for 1,000+ products and orders	Lowest review count (12) and rating (3.3) of any app on this list
Category mapping templates help with bulk product updates	Order syncing can't currently be turned off if you only want product sync
Multi-store management from a single dashboard	Some reviewers report slow support response during urgent issues

Pricing

Free, with no paid tier currently listed.

Final Verdict

Consider this if you're sitting on a large catalog and want free bulk syncing, just set realistic expectations on support given the small, mixed review base, and watch order syncing closely if product-only sync was your intent.

Installing a Third-Party App (Quick Steps)

Screens differ from app to app, but setting up any of these TikTok Shop Shopify integrations tends to follow the same basic sequence:

1. Install your chosen connector from the Shopify App Store and grant it access to your product and order data.
2. Link your TikTok Shop seller account using the app's onboarding, which handles authentication against TikTok's API.
3. Map Shopify locations to TikTok warehouses if you operate more than one location, so regional stock counts stay correct.
4. Push products from Shopify to TikTok Shop, letting category-mapping tools assign each item to the right TikTok category and its required attributes.
5. Turn on inventory sync so stock updates flow both directions and neither channel oversells.
6. Switch on order sync so TikTok Shop orders arrive in Shopify automatically, no manual export or re-entry needed.
7. Run a small test batch first. Push a handful of products and a couple of test orders before you bulk-upload the full catalog, so any category-mapping issues show up early instead of after 1,000 listings go live.

Common TikTok Shop Sync Problems and How to Avoid Them

• Orders stuck on TikTok, never reaching Shopify. Nine times out of ten this traces back to a broken connection, an expired API token, or an app that quietly stopped syncing, something QuickSync reviewers have flagged more than once. Get in the habit of checking your app's sync log rather than assuming no news is good news.
• Stock counts drifting apart. Mismatched inventory almost always comes down to a Shopify location that was never mapped to the correct TikTok warehouse in a multi-location setup. Nail down warehouse mapping before you run your first bulk sync.
• Products refusing to sync at all. Category mapping failures are the usual culprit, TikTok bounces anything missing a category-required attribute. AI auto-mapping apps (SPL, Ecomzier Tiktok Shop Connector, CedCommerce, AfterShip) cut this down significantly, but spot-check rejected listings by hand anyway.
• A wave of cancelled TikTok orders. Stock mismatches between platforms are usually to blame. A real two-way, real-time sync closes that gap far better than an app that only pushes one direction, Shopify to TikTok.
• Two connectors fighting over the same TikTok Shop. Letting two apps sync products or inventory at once is a fast track to duplicate listings and conflicting stock, exactly what one Ownbase review describes. Settle on a single app as your source of truth.

---

Final Thoughts

If you're not sure where to begin, start with SPL. It's free, handles two-way product, inventory, and order sync with AI category mapping, and no other app on this list has a bigger or more reliable review base. Run Ecomzier Tiktok Shop Connector, our own app, alongside it if you'd like a direct line to our support team. Beyond that, only bring in a specialist once you've identified an actual gap: AfterShip for creator partnerships, DPL for one flat bill no matter your order count, CedCommerce for a dedicated account manager, M2E if TikTok Shop is one of several marketplaces you're expanding into, Ownbase for field-level control over what syncs, SKU IQ if a physical POS is in your stack, or ShopSync for free bulk syncing on a bigger catalog.

Between them, these ten apps span free entry-level sync, fully managed support, creator marketplace access, flat-rate billing, multi-marketplace and multi-POS reach, and low-cost options for smaller catalogs. Match your pick to your catalog size, order volume, and how many shops, regions, or channels you're actually running right now, then reassess as TikTok Shop rolls out to more markets.
