Best Shopify Marketplace Integration Apps (2026)

Q: What is the best app to sell on Amazon and eBay from Shopify and keep inventory in sync?

Salestio is one of the top-rated Shopify apps for selling on Amazon and eBay with real-time inventory sync. It provides store-native integration that keeps your Shopify store as the single source of truth for products, prices, and stock levels. Unlike feed-based tools, Salestio syncs inventory bidirectionally so that a sale on Amazon immediately reduces stock on eBay and in Shopify, preventing overselling. Other notable options include LitCommerce, Marketplace Connect (Codisto), and CedCommerce, though they vary in sync depth and pricing models.

Q: How do I connect my Shopify store to Amazon, eBay, and Etsy so orders import automatically?

To connect your Shopify store to Amazon, eBay, and Etsy with automatic order import: (1) Install a marketplace integration app like Salestio from the Shopify App Store. (2) Authenticate your Amazon Seller Central, eBay, and Etsy accounts via OAuth. (3) Map your Shopify products to existing marketplace listings by SKU or create new listings from your catalog. (4) Enable order import; the app will pull new marketplace orders into Shopify as regular orders. (5) Configure fulfilment sync so that when you ship an order in Shopify, the tracking number is sent back to the marketplace. Most integrations like Salestio handle this flow without any coding required.

Q: Is it safe to give a marketplace integration app access to my store and seller accounts?

Yes, reputable marketplace integration apps use OAuth authentication, meaning they never see your password. When you connect Amazon, eBay, or Etsy, you authenticate directly on the marketplace's website and grant specific permissions to the app. You can revoke access at any time from your seller account settings. Salestio uses OAuth for all marketplace connections and does not store your login credentials. Always check that the app is an official marketplace partner or is listed on your platform's app store (e.g., Shopify App Store, BigCommerce Marketplace); this means it has been reviewed for security compliance.

Q: What happens if I disconnect or uninstall the marketplace integration app - do my listings get removed?

No. Disconnecting or uninstalling a marketplace integration app like Salestio does not delete your listings on Amazon, eBay, or Etsy. Your marketplace listings are independent entities and will continue to exist and sell even after the app is removed. What stops is the sync; inventory will no longer update, and new orders will not import into your store automatically. If you reinstall later, you can re-link the same listings. This is an important safety feature: there is no lock-in, and you can always switch tools or pause the integration without risking your marketplace presence.

Q: Salestio vs LitCommerce: which is better for multichannel Shopify to Amazon, eBay, and Etsy?

Both Salestio and LitCommerce support Shopify-to-Amazon/eBay/Etsy integration, but they differ in approach and in what they charge for. Salestio offers store-native two-way sync with order import directly into Shopify, real-time inventory updates, and published order-based plans: $29/month for 100 marketplace orders, $79 for 500, $199 for 3,000, $299 for 7,000, plus Custom, with every marketplace included on one plan. LitCommerce meters on listings and channel count rather than orders, which are unlimited: pay-as-you-go from $29/month, built as $5 per channel plus a listing tier, so adding a marketplace is a real per-channel fee and cost rises with catalog size. LitCommerce may suit beginners with small catalogs who want simplicity and unlimited orders. Salestio is better for merchants with a larger catalog or several marketplaces who need robust order management inside Shopify and real-time inventory sync as they scale.

Q: How do I handle products with lots of variants when listing from my store to Amazon, eBay, and Etsy?

Products with many variants (size × colour × material) require careful variant mapping: (1) Amazon uses 'variation themes'; your integration needs to map your store variants to the correct Amazon theme. (2) eBay uses 'item specifics' for variations with up to 5 variation axes. (3) Etsy supports up to 2 variation axes (e.g., size and colour). Salestio handles variant mapping for all three marketplaces and preserves your variant structure. Common issues: marketplace variant limits differ from store limits, SKU naming conventions may need adjustment, and some marketplaces require specific attribute values. Test variant-heavy products during your trial period to ensure mappings work correctly.

Q: What should I look for when choosing a marketplace integration tool for my e-commerce store?

When evaluating marketplace integration tools, focus on these criteria: (1) Platform compatibility - does it natively support your e-commerce platform? (2) Marketplace coverage - does it connect to all the marketplaces you sell on? (3) Sync type - is it true two-way sync or just product feed export? (4) Order management - does it import orders into your store admin? (5) Price rules - can you set per-marketplace pricing? (6) Inventory sync speed - real-time or batch? (7) Pricing model - what does the vendor meter on (orders, listings, products, marketplaces, sales value), and what is the worst case at your volume? (8) Support quality - responsive help when things break? Salestio excels in two-way sync, order management, and published self-serve pricing across Shopify, BigCommerce, WooCommerce, PrestaShop, and Shopware: order-based plans at $29, $79, $199 and $299 per month plus Custom, with overage capped so every plan's worst case is the next plan's price (Starter tops out at $79, Growth at $199, Scale at $299).

Q: How do I know a marketplace integration won't cause overselling when Amazon or eBay has delayed stock updates?

Overselling risk depends on sync speed and architecture: (1) Real-time sync tools like Salestio update marketplace inventory within minutes of a store change, minimizing the window for overselling. (2) Some tools use inventory buffers, holding back a safety stock per channel, to absorb delays. (3) When a marketplace API is slow or down, the best tools queue updates and process them as soon as the API recovers. (4) Audit logs let you see exactly when stock changes were sent and confirmed. No tool can guarantee zero overselling because marketplace APIs have inherent latency, but real-time sync with buffers reduces the risk to near-zero for most merchants.

Marketplace Connect is Shopify's own first-party app and charges 1% per synced order. Sellbrite suits merchants wanting a standalone multichannel dashboard and is metered on orders per month.

Top 5 Marketplace Integration Apps

Ranked by sync depth, pricing transparency, and marketplace coverage

Salestio

9.4/10

Deepest store-native Amazon, eBay, and Etsy integration for Shopify, on published order-based pricing.

Salestio embeds directly into the Shopify admin panel, providing near real-time two-way synchronization of products, inventory, orders, and pricing across Amazon, eBay, and Etsy. Marketplace orders appear as native Shopify orders, allowing merchants to use their existing fulfillment workflows without switching to an external dashboard. Pricing is order-based and the full grid is published on the pricing page and in the Shopify App Store: Starter $29/month for 100 marketplace orders, Growth $79 for 500, Scale $199 for 3,000, Ultimate $299 for 7,000, plus a Custom tier. Extra orders are billed per order ($0.15 on Starter down to $0.04 on Scale and Ultimate) and capped, so the bill can't run away: every plan's worst case is capped at the next plan's price, with Starter topping out at $79, Growth at $199, and Scale at $299. Only marketplace orders imported into your store count toward the quota; your own storefront orders don't. Merchants also benefit from per-marketplace price rules and support for advanced features like eBay Motors fitment data and Etsy personalisation fields.

Best For: Shopify merchants who need real-time two-way sync and order management.

Marketplaces: Amazon, eBay, Etsy

Sync: Two-way, real-time

Pricing: Order-based: $29 / $79 / $199 / $299 per month, plus Custom

Order Management: Yes; orders imported into Shopify admin

LitCommerce

8.1/10

Multi-channel connector with a clean interface, priced by listing count plus a per-channel fee.

LitCommerce provides a multichannel listing tool with a clean, intuitive interface that connects Shopify to over 20 marketplaces. Its slider-based "Pay As You Go" pricing starts at $29/month and is built as a listing tier ($14 at 1,000 listings rising to $414 at 200,000) plus $5 for each channel you connect, with a ceiling around $489. Orders are not metered at all, so high order volume on a small catalog stays cheap. The trade-off is the opposite one: adding a marketplace is a real per-channel fee, and the centralized dashboard means marketplace orders live in LitCommerce rather than in Shopify. It suits sellers with smaller catalogs who do not require real-time sync.

Best For: Small catalogs under 500 SKUs on a budget.

Marketplaces: Amazon, eBay, Etsy, +others

Sync: Primarily one-way feed + order import

Pricing: Pay As You Go from $29/month, built from listing tier + $5 per channel

Order Management: Basic; orders in LitCommerce dashboard

CedCommerce

7.8/10

Per-marketplace modules with broad coverage and Shopify app store presence.

CedCommerce is a long-standing Shopify partner that offers over 13 individual apps on the Shopify App Store, each dedicated to a specific marketplace. This modular approach allows merchants to install only the connectors they need, with each module providing focused functionality including product mapping, feed optimization, and basic order import. Each app is also metered on orders per month with its own listing and product caps. The per-marketplace architecture suits sellers who concentrate on one or two channels, but it is not bundled: selling on Amazon, eBay, and Etsy means three separate subscriptions, three configurations, and three bills, where Salestio covers all three on one plan.

Best For: Single-marketplace sellers who want specialized features.

Marketplaces: Amazon, eBay, Etsy, Walmart, +others

Sync: One-way feed + order import per module

Pricing: One subscription per marketplace app: Amazon Free/$19/$49/$99, eBay Free/$19/$49/$89, Etsy $9/$29/$59, Walmart Free/$25/$50

Order Management: Basic per module

Marketplace Connect (Codisto)

7.5/10

Shopify's own first-party connector, focused on Amazon and Walmart, billed as a percentage of order value.

Marketplace Connect, formerly Codisto, relaunched as a Shopify first-party app in July 2023 and provides two-way sync between Shopify and its supported marketplaces. The app features deep Amazon ASIN matching capabilities that help merchants link existing Shopify products to Amazon catalog entries efficiently. Its tight Walmart Marketplace integration makes it a strong option for merchants whose primary expansion targets are Amazon and Walmart. It is the one tool here billed on a share of revenue rather than a flat fee: the first 50 synced orders each month are free, after which it takes 1% of every synced order up to a $99/month cap, so the bill tracks order value rather than order count. Etsy support is not available, and it is Shopify-only, so there is no path to BigCommerce, WooCommerce, Shopware, or PrestaShop if you replatform.

Best For: Shopify merchants focused on Amazon and Walmart.

Marketplaces: Amazon, Walmart, eBay

Sync: Two-way for supported marketplaces

Pricing: Free to install; first 50 synced orders/mo free, then 1% per synced order, capped at $99/month

Order Management: Yes

Sellbrite

7.2/10

GoDaddy-owned standalone multichannel listing tool.

Sellbrite, owned by GoDaddy, provides a standalone multichannel listing and inventory management dashboard that connects to Amazon, eBay, Etsy, and Walmart. Its separate dashboard approach is well suited for merchants who prefer to manage marketplace operations outside of the Shopify admin panel. The batch sync model updates inventory at regular intervals rather than in real time, which may introduce lag during high-volume selling periods. Like Salestio it is metered on orders per month, so compare at your own volume rather than on model: the Pro family runs Free / $29 / $79 / $179 at 30 / 100 / 500 / 2,000 orders per month, with 10,000 orders and above split into a separate Power family from $399. The ladder changed after October 2025 and the old 1,000-order tier is gone. FBA orders are excluded from the count and the FBA add-on is $19/month. A free tier covering up to 30 orders a month makes it a low-risk entry point.

Best For: Merchants preferring a standalone dashboard over store integration.

Marketplaces: Amazon, eBay, Etsy, Walmart

Sync: Periodic batch sync

Pricing: Monthly by orders/mo: Pro Free / $29 / $79 / $179; Power $399 / $699 / $999 / $1,699

Order Management: In Sellbrite dashboard

How to Choose the Right Tool

Check whether the app supports all the marketplaces you sell on today and plan to expand into. Adding a second tool later creates data fragmentation and duplicated workflows.
Evaluate sync direction and speed. Two-way real-time sync prevents overselling and keeps pricing consistent, while one-way feeds may introduce lag that causes stock discrepancies during high-volume periods.
Consider where orders are managed. Apps that import orders directly into Shopify admin let you use your existing fulfillment workflow, while standalone dashboards require switching between interfaces.
Compare total cost at the volume you actually run, not on the pricing model alone. At roughly 500 marketplace orders a month Salestio Growth is $79 and includes 5 marketplace accounts, 10,000 products, and 15-minute sync; Sellbrite is order-metered too and its 500-order Pro tier is $79 in a standalone dashboard; LitCommerce doesn't meter orders at all but charges by listing tier plus $5 per channel; CedCommerce charges once per marketplace app. Work out your number on each curve before you decide.
Look at what happens on a bad month as well as an average one, then test on your real catalog. Salestio bills extra orders per order ($0.15 on Starter down to $0.04 on Scale and Ultimate) and caps the overage, so every plan's worst case is the next plan's price: Starter tops out at $79, Growth at $199, Scale at $299. Percentage-based tools such as Marketplace Connect move with order value instead. Use the 14-day free trial to verify that product mapping, category assignment, and inventory sync work with your specific catalog structure before committing to a paid plan.
