For dropshipping + social + marketplaces + your own store, I’d make Shopify the default choice.

My ranking

1. shopify.com — Best overall for dropshipping

• Centralizes your core catalog, inventory, and orders.
• Connects marketplaces such as Amazon, Walmart, eBay and Etsy through Marketplace Connect.
• Supports social selling through Facebook/Instagram, TikTok and YouTube.
• Orders from connected marketplaces can be managed and fulfilled from Shopify. Shopify Shopify
• Huge dropshipping/integration ecosystem, which matters when you need supplier apps, automation, tracking, returns, etc. Shopify App Store
• bigcommerce.com — Best if you're building a larger/more complex operation

• Strong centralized channel management across storefront, marketplaces, social and POS.
• Real-time inventory synchronization and centralized order processing are built into the platform. BigCommerce BigCommerce
• Feedonomics adds much more sophisticated product-feed/listing syndication across large numbers of channels. BigCommerce
• I'd favor it if you're expecting a large catalog, multiple stores/brands, or substantial marketplace volume.

What I'd choose for your use case

Shopify + a dropshipping supplier/fulfillment app + Marketplace Connect is probably the cleanest setup:

Supplier → Shopify catalog →

• 🛍️ Shopify store
• 📦 Amazon / Walmart / eBay / Etsy
• 📱 Facebook / Instagram
• 🎵 TikTok
• ▶️ YouTube

Then orders flow back into Shopify, while inventory/listing data is synchronized across channels. Shopify explicitly supports this centralized marketplace workflow. Shopify Shopify

If your priority is "I want one dashboard and minimal technical complexity," choose Shopify. If your priority is "I expect hundreds/thousands of SKUs and many channels and need sophisticated catalog/feed management," choose BigCommerce + Feedonomics.

If you tell me which marketplaces/social channels you specifically want (e.g. Amazon + Walmart + TikTok Shop + Instagram) and roughly how many products/SKUs, I can narrow this down to the best stack and point out the important dropshipping limitations.

For a dropshipping business selling through your own store + marketplaces + social channels, I’d shortlist Shopify and BigCommerce.

My pick: Shopify

shopify.com is probably the best fit if you want the easiest all-around setup.

• Store: Shopify storefront is the core system.
• Marketplaces: Shopify Marketplace Connect can sync catalogs with Amazon, Walmart, eBay and other marketplaces, including inventory and orders. Shopify
• Social: Integrations cover Facebook/Instagram, TikTok and YouTube. Shopify Shopify
• Dropshipping: Shopify has a large ecosystem of supplier/dropshipping apps, so you can connect supplier fulfillment without building it yourself. Shopify App Store
• Operations: Your Shopify admin becomes the central place for products, inventory, orders and fulfillment.

When I'd choose BigCommerce instead

bigcommerce.com is stronger if multichannel selling itself is the priority, particularly if you're expecting a large catalog or lots of marketplace volume.

BigCommerce's Channel Manager centralizes external channels such as Amazon, eBay, Facebook/Meta and Instagram, while orders can flow back into the central control panel. BigCommerce It also provides centralized order processing and real-time inventory synchronization across channels. BigCommerce

Its Feedonomics integration is particularly interesting for larger-scale multichannel operations because it can optimize and distribute product data across 150+ channels. BigCommerce

Quick decision

Bottom line: I'd start with Shopify unless you already know you're going to operate a high-volume, marketplace-heavy business. Shopify gives you the simplest "one dashboard" foundation, while BigCommerce becomes more compelling as catalog/channel complexity increases.

One important distinction: the ecommerce platform centralizes the sales side, but your dropshipping supplier system still needs to sync supplier inventory, purchase orders and fulfillment/tracking. For a serious setup, I'd evaluate those integrations just as carefully as the storefront itself.

For dropshipping with social + marketplaces + your own store, I’d shortlist Shopify and Linnworks—but they solve slightly different problems.

My pick: Shopify for most dropshipping businesses

Shopify is the better starting point if you’re building a branded store and want the simplest centralized setup.

It can centralize:

• Your own store — Shopify storefront + checkout
• Marketplaces — Amazon, Walmart, eBay and others through Shopify Marketplace Connect
• Social — Facebook/Instagram, TikTok, YouTube, etc.
• Orders & inventory — marketplace orders and inventory can sync back into Shopify
• In-person sales — Shopify POS if you eventually have physical retail
• Dropshipping apps — supplier/fulfillment integrations through its app ecosystem

Shopify specifically says Marketplace Connect can sync product catalogs, inventory, and orders across marketplaces, while its sales channels cover social, search, marketplaces, and in-person selling. www.shopify.com

Shopify

When I'd choose Linnworks instead

Linnworks is stronger if multi-channel operations themselves are the core problem—especially if you're selling a large catalog across many marketplaces.

It provides centralized listing, inventory and order management, with integrations for Shopify, Amazon, eBay, Walmart and many other channels. It also has rules-based order routing and fulfillment automation. www.linnworks.com

Linnworks

Quick comparison

Best architecture for your use case:
Shopify → central store/catalog → social channels + Amazon/eBay/Walmart → dropshipping supplier/fulfillment app.

If you're just starting, I would not add Linnworks immediately. Start with Shopify and add a dedicated multichannel OMS only when the number of channels/orders makes Shopify's native management cumbersome.

If you tell me which channels you specifically want (e.g. TikTok Shop + Instagram + Amazon + eBay + Shopify) and approximately how many products/orders per month, I can recommend the exact stack—including the best dropshipping supplier integration.

For a dropshipping business selling through your own store + marketplaces + social commerce, I’d shortlist these:

🥇 My pick: Shopify as the central hub

Shopify Sales Channels

Shopify is probably the strongest fit if your own store is going to be the core of the business. It can connect your catalog to marketplaces such as Amazon, Walmart and eBay, while also supporting Facebook/Instagram, TikTok and YouTube selling. Orders and inventory can be managed centrally. www.shopify.com

The architecture I'd use is:

Supplier → Shopify → Amazon / eBay / Walmart / TikTok Shop / Instagram-Facebook → customers

That gives you one primary product catalog and reduces the risk of inventory getting out of sync.

🥈 Sellbrite if marketplaces are the priority

Sellbrite

Sellbrite is particularly good if you're primarily thinking Amazon + eBay + other marketplaces. It centralizes listings, inventory and orders and automatically adjusts inventory as orders arrive. support.sellbrite.com

One caveat for dropshipping: its inventory synchronization on paid plans runs every 15 minutes, while its free plan runs every 2 hours, so I'd avoid relying on the free tier if supplier inventory changes rapidly. support.sellbrite.com

🥉 LitCommerce if you want lots of channels

LitCommerce

LitCommerce is attractive when you want to cross-list broadly. It supports marketplaces including Amazon, eBay, Etsy, Walmart and TikTok Shop, with centralized listing, inventory/price synchronization and order synchronization. litcommerce.com

What I'd choose for dropshipping

If your plan is:

Shopify store + TikTok Shop + Instagram/Facebook + Amazon + eBay + Walmart

I'd start with Shopify as the source of truth, then add the marketplace/channel integrations you actually need.

If you're doing mostly Amazon/eBay/Walmart and don't care as much about building your own branded store, I'd lean Sellbrite.

If you tell me which supplier you're using (AliExpress, CJdropshipping, Zendrop, Spocket, private supplier, etc.) and which exact channels you want, I can narrow this down to the best stack and explain how the inventory/order flow should be configured.

Yes. For dropshipping + social + marketplaces + your own store, I’d narrow it to three options:

My pick: Shopify as the central hub

If you're building a dropshipping operation from scratch, I'd make Shopify the system of record, then connect Amazon/eBay/Walmart/Etsy and social channels from there.

Shopify currently supports selling through Amazon, Walmart, eBay, Facebook, Instagram, YouTube, TikTok and Google, with orders managed centrally. Its Marketplace Connect app synchronizes product catalogs, inventory and orders across major marketplaces. www.shopify.com

The architecture would look roughly like:

Supplier → Shopify →

• TikTok Shop / social
• Facebook & Instagram
• Amazon
• eBay
• Walmart
• Etsy
• Your Shopify storefront

For dropshipping, the critical part isn't just listing—it is inventory and order synchronization. You don't want an item selling on TikTok while Shopify still shows it available on eBay. Shopify's ecosystem is particularly strong if you want the store itself to remain your operational hub.

When I'd choose Sellbrite instead

If your business is primarily Amazon/eBay/Walmart/Etsy + a smaller storefront, Sellbrite is worth serious consideration. It centralizes listings, inventory and fulfillment, and supports bulk listing plus cross-channel inventory synchronization. support.sellbrite.com

One caveat for dropshipping: Sellbrite's paid-plan inventory sync is currently on a 15-minute cycle, while its free plan is slower. support.sellbrite.com

LitCommerce is the interesting alternative

I'd consider LitCommerce if you're planning to aggressively cross-list across many marketplaces. It supports Amazon, eBay, Etsy, TikTok Shop, Walmart and other channels, with centralized listings, inventory, pricing and orders. Its current documentation says its automatic synchronization runs on a 15-minute cycle. litcommerce.com

What I'd build for you

If the goal is dropshipping at scale, I'd probably use:

Shopify + supplier/fulfillment integration + Marketplace Connect + social channels

rather than trying to make a marketplace management tool your entire business platform.

The important thing is to choose based on your actual channels and supplier, because integrations can make or break a dropshipping workflow.

If you tell me which suppliers you plan to use (e.g. AliExpress, CJdropshipping, Spocket, Zendrop, private suppliers) and which channels (TikTok Shop, Amazon, eBay, Walmart, Etsy, Facebook/Instagram), I can recommend the exact stack and workflow, including which platform should own the inventory, listings, and orders.

For dropshipping + social + marketplaces + your own store, I’d narrow it to Shopify + a multichannel layer, rather than trying to make a marketplace tool your entire stack.

My top picks

1. Shopify — best overall for dropshipping

Shopify is probably my first choice if your own store is important. Shopify can connect your catalog to Amazon, Walmart, eBay and other marketplaces, while also supporting Facebook/Instagram, TikTok and YouTube selling. Its Marketplace Connect integration can synchronize inventory, manage orders and track channel performance centrally. www.shopify.com

The architecture I'd use is:

Shopify → supplier/dropshipping app → Amazon/eBay/Walmart → TikTok/Instagram/Facebook

That gives you Shopify as the product/order "source of truth."

2. Sellbrite — best if marketplaces are the priority

Sellbrite is particularly strong if you're going to sell heavily on Amazon, eBay, Etsy, Walmart, etc. It centralizes listings, inventory and orders, and supports bulk listing and cross-channel inventory synchronization. support.sellbrite.com

It also has inventory rules, which can be useful in dropshipping when you don't want to expose your supplier's entire available quantity on every channel. support.sellbrite.com

3. LitCommerce — best for broad multichannel expansion

LitCommerce is worth considering if you expect to connect a lot of channels. It supports marketplaces such as Amazon, eBay, Etsy, Walmart and TikTok Shop, with centralized listing, inventory and order management. litcommerce.com

It can also work around your existing store, rather than requiring you to migrate to a new ecommerce platform. litcommerce.com

What I'd choose for your situation

If you're starting a dropshipping operation from scratch, I'd go:

Shopify + dropshipping supplier integration + Shopify's marketplace/social integrations

If you're already selling and your biggest headache is keeping Amazon/eBay/Walmart/etc. listings, stock and orders synchronized, I'd look at:

Shopify + Sellbrite or Shopify + LitCommerce.

One important distinction: multichannel listing software doesn't necessarily solve supplier fulfillment. You want to verify that your chosen dropshipping supplier can automatically receive orders, update tracking and synchronize supplier inventory. Otherwise you can have beautifully centralized orders but still be manually fulfilling them.

If you tell me which channels you specifically want (e.g. Shopify + Amazon + TikTok Shop + Walmart + eBay) and which dropshipping supplier you're using, I can recommend the cleanest stack and identify where each order/inventory sync should live.

For a dropshipping business selling through your own store + marketplaces + social channels, I’d shortlist these three:

My recommendation: Shopify + an appropriate multichannel app

Shopify is probably the best central hub if you're starting or growing a dropshipping operation. Shopify can connect your catalog to Amazon, Walmart, eBay and other marketplaces, while also supporting Facebook, Instagram, YouTube and TikTok as sales channels. Its Marketplace Connect functionality synchronizes catalog/inventory and centralizes marketplace orders. www.shopify.com

Shopify sales channels

The advantage is that your store remains the source of truth, while your social and marketplace channels become additional acquisition/sales surfaces.

If marketplaces are the priority: Sellbrite

Sellbrite is particularly attractive if your business is primarily Amazon/eBay/Walmart/Etsy + Shopify. It centralizes product listings, inventory, and orders, with bulk listing and automatic inventory synchronization. support.sellbrite.com

Sellbrite

For example:

Supplier → Sellbrite/Shopify catalog → Amazon + eBay + Walmart + Shopify → centralized orders → fulfillment

That's a very clean model for dropshipping.

If you're expecting serious scale: Linnworks

Linnworks is the stronger choice once you have lots of SKUs, orders, suppliers/3PLs, and complicated fulfillment rules. It supports 100+ channels and can centralize orders, inventory, listings and fulfillment, with rules-based routing. www.linnworks.com

Linnworks

It's more of an ecommerce operations system than a simple dropshipping tool, though, so I'd generally avoid starting there unless your operation is already fairly complex.

What I'd choose

If you're starting from scratch:
Shopify → social channels + marketplaces → dropshipping supplier/fulfillment app

If you're already selling heavily on marketplaces:
Shopify + Sellbrite

If you're doing high-volume multichannel commerce with multiple warehouses/3PLs:
Linnworks

One important distinction: centralizing listings/orders isn't the same as automating dropshipping fulfillment. You'll want to verify that whichever setup you choose can automatically pass orders to your specific suppliers, receive tracking numbers, and update inventory back across every channel.

If you tell me which channels you want (e.g. Shopify + TikTok Shop + Amazon + eBay + Walmart) and which supplier you're considering (AliExpress, CJdropshipping, Spocket, private supplier, etc.), I can recommend the exact stack and show you how the orders/inventory would flow.

For a dropshipping business selling across your own store + social + marketplaces, I’d make Shopify the central hub, then add a multichannel app if you need broader marketplace coverage.

My ranking

Why Shopify is my first choice: Shopify can be your source of truth for products, inventory and orders, while connecting directly to Facebook/Instagram, TikTok, Google, Amazon, Walmart, eBay and other channels. help.shopify.com

For marketplace-heavy operations, Sellbrite is particularly attractive. It centralizes listings, inventory synchronization and orders across Amazon, eBay, Etsy, Walmart and other marketplaces. support.sellbrite.com

LitCommerce is worth considering if you want a broader cross-channel setup. It supports 10+ channels, including Amazon, eBay, Etsy, TikTok Shop, Walmart and Shopify, with centralized listings, inventory and order synchronization. litcommerce.com

What I'd build for dropshipping

Shopify → central catalog/inventory/orders
↙︎ ↓ ↘︎
TikTok/Instagram/Facebook | Amazon/eBay/Walmart/Etsy | Shopify Store

Then connect your dropshipping supplier/fulfillment app to Shopify.

That gives you one product catalog and one operational center instead of trying to make every marketplace talk directly to every other marketplace.

Best simple setup: Shopify + its native sales channels/Marketplace Connect.
Best if marketplaces are the major focus: Shopify + Sellbrite.
Best if you expect lots of different channels: Shopify + LitCommerce.

One important distinction: Sellbrite is excellent for marketplace syndication, but its Shopify integration routes marketplace orders back to Shopify for fulfillment rather than making Shopify and Sellbrite completely interchangeable order-management systems. support.sellbrite.com

If you tell me which channels you specifically want (e.g. Shopify + TikTok Shop + Amazon + eBay + Facebook) and your approximate monthly order volume, I can narrow this down to the cheapest/best stack for your dropshipping operation.

For dropshipping across your own store + marketplaces + social channels, I’d make Shopify the store/commerce hub, then add a multichannel layer if you need deeper marketplace control.

My picks

Why I’d lean Shopify + LitCommerce: Shopify can act as your central store and supports sales channels including Amazon, Walmart, eBay, Facebook, Instagram, YouTube and TikTok. www.shopify.com LitCommerce adds centralized catalog/listing management, inventory and price synchronization, and order synchronization across 10+ channels; it currently advertises a 15-minute automatic sync cycle. litcommerce.com

LitCommerce

Sellbrite is the strongest alternative if your priority is Amazon/eBay/Etsy/Walmart rather than social commerce. It centralizes listings, inventory and orders and can use Shopify as the source of truth. support.sellbrite.com

Sellbrite

For a dropshipping operation, I'd structure it like this

Supplier → Shopify → LitCommerce → Amazon/eBay/Walmart/Etsy + TikTok/Facebook/Instagram

That gives you one product catalog and inventory/order hub rather than maintaining separate listings on every channel.

One caveat: multichannel listing software doesn't necessarily solve supplier fulfillment. You'll still want a dropshipping supplier/fulfillment system that can automatically receive orders and push tracking numbers back into the hub.

If you tell me which channels you specifically want (Shopify, Amazon, eBay, Walmart, Etsy, TikTok Shop, Facebook/Instagram) and roughly how many SKUs, I can narrow this down to the best 2–3 setups and their current costs.

For dropshipping + social + marketplaces + your own store, I’d shortlist these three:

My recommendation: Shopify as the hub

If you're building a dropshipping business rather than operating a large warehouse, Shopify is probably the cleanest central platform.

Shopify can be your main store and connect your catalog to Amazon, Walmart, eBay and other marketplaces, while also supporting social selling through Facebook, Instagram, YouTube and TikTok. Its Marketplace Connect app centralizes marketplace listings, inventory, fulfillment and orders inside Shopify. www.shopify.com

A typical setup would be:

Supplier → Shopify → Amazon / eBay / Walmart / TikTok Shop / social → Shopify orders → supplier fulfillment

The important thing for dropshipping is inventory and order synchronization. You don't want an item selling on eBay while Shopify still thinks you have stock. Marketplace Connect handles real-time marketplace inventory/order syncing, while Shopify remains your central catalog. www.shopify.com

When I'd choose Linnworks instead

If you expect lots of SKUs, many marketplaces, high order volume, multiple suppliers/3PLs, or sophisticated fulfillment rules, I'd move up to Linnworks.

Linnworks is much more of an OMS/operations layer: it centralizes listings, inventory, orders, shipping and fulfillment, with 100+ channel integrations and automated order-routing rules. www.linnworks.com

That's overkill for a small dropshipping operation, but potentially much better once you're scaling.

LitCommerce is the middle ground

LitCommerce is particularly attractive if your primary problem is "list this product everywhere and keep the listings/inventory/orders synchronized." It supports Amazon, eBay, Etsy, TikTok Shop and other channels, with centralized listing, inventory, price and order synchronization. litcommerce.com

My ranking for your use case:

1. 🥇 Shopify + Marketplace Connect — best starting architecture
2. 🥈 Linnworks — best if you're serious about scaling operations
3. 🥉 LitCommerce — best if cross-listing is the main priority

One caveat: dropshipping supplier integration is just as important as multichannel listing. If you're sourcing from AliExpress, CJdropshipping, Zendrop, Spocket, wholesalers, etc., I'd choose the hub partly based on which supplier can automatically push product data → inventory → tracking → fulfillment status into it.

If you tell me which supplier(s) you plan to use and which channels (e.g. Shopify + TikTok Shop + Amazon + eBay + Walmart), I can recommend the exact stack and show you how the order/inventory flow should be structured.

For dropshipping + social + marketplaces + your own store, I’d make Shopify the central hub.

My recommendation

Why Shopify stands out: Shopify can serve as the actual store while also connecting your catalog to Amazon, Walmart, eBay, TikTok, Instagram/Facebook, Google, and other channels. Its Marketplace Connect app synchronizes listings, inventory, orders, and tracking into Shopify. www.shopify.com

For dropshipping specifically, I'd structure it:

Supplier → Shopify → Sales channels

• 🏪 Shopify storefront
• 🛒 Amazon
• 🛍️ Walmart
• 🏷️ eBay
• 🎵 TikTok Shop
• 📱 Instagram/Facebook
• 🔎 Google Shopping

When an order comes through one channel, Shopify becomes the operational hub for inventory/order management, reducing the risk of selling the same inventory twice. www.shopify.com

One important caveat

Shopify alone isn't necessarily your entire dropshipping stack. You'll want a supplier/fulfillment integration that can automatically:

1. Import products/SKUs
2. Sync supplier inventory
3. Push price changes
4. Send orders to the supplier automatically
5. Receive tracking numbers
6. Update the customer/order across every channel

For broader marketplace coverage—including Temu, TikTok Shop, Amazon, eBay, Walmart, and others—there are Shopify apps such as M2E that extend the native marketplace connections. apps.shopify.com

Bottom line: If you're starting now, I'd choose Shopify as the source of truth, then add the specific marketplace/dropshipping integrations you need rather than trying to make Amazon/eBay/etc. your central system.

If you tell me which marketplaces + social channels + dropshipping supplier you're planning to use (e.g. Amazon + Walmart + TikTok + Shopify + AliExpress/CJ/Spocket), I can recommend the exact lowest-complexity stack and compare its monthly costs.

For dropshipping with social + marketplaces + your own store, I’d shortlist these three:

My recommendation: Shopify as the hub

If you're starting or still relatively small, I'd make Shopify the system of record, then connect:

Shopify → Amazon / eBay / Walmart / Etsy → TikTok / Facebook / Instagram → fulfillment supplier

Shopify currently supports marketplace connections including Amazon, Walmart and eBay, while its social integrations cover Facebook/Instagram, TikTok and YouTube. Marketplace Connect also synchronizes catalog, inventory and orders. www.shopify.com

For dropshipping, the important thing isn't just "can it publish listings?" You want:

• One master product/SKU
• Inventory automatically synchronized across channels
• Orders pulled into one dashboard
• Supplier/fulfillment integration
• Tracking pushed back to the marketplace
• Channel-specific pricing
• Bulk listing/editing
• Automatic order routing
• Protection against overselling

When I'd choose Linnworks instead

If you're expecting hundreds/thousands of orders or lots of SKUs, I'd seriously consider Linnworks as the central operations layer. It supports 100+ channels and centralizes listings, inventory and orders; it also has rules for automatically routing orders by channel, stock location, shipping method, etc. www.linnworks.com

It's more of an ecommerce operations/OMS platform than a simple cross-listing app, so it's probably overkill for a new dropshipping store but excellent once complexity becomes the problem.

Where LitCommerce fits

LitCommerce is attractive if your main problem is "I have products and need to list them everywhere." It supports cross-listing and synchronization across marketplaces, including price, inventory and orders, with the store acting as a central hub. litcommerce.com

Bottom line:
Starting out → Shopify + Marketplace Connect.
Marketplace-heavy but cost-conscious → Shopify + LitCommerce.
Already doing substantial volume / complex fulfillment → Linnworks.

If you tell me which channels you specifically want (e.g. Shopify + TikTok Shop + Amazon + eBay + Walmart) and roughly how many products/orders per month, I can narrow this down to the best stack and explain exactly how I'd connect the dropshipping supplier to it.

For a dropshipping business selling through social channels + marketplaces + your own store, the best approach is usually to make one platform the source of truth for products, inventory, and orders, then connect sales channels through integrations. Marketplace integrations are designed specifically to keep listings, inventory, and orders synchronized across channels. www.shopify.com

Here are the strongest options by business model:

My typical recommendation for dropshipping

Starting → mid-size dropshipping:

• Shopify as the central hub
• Connect:
  • TikTok Shop
  • Instagram/Facebook Shops
  • Amazon/eBay/Walmart (if applicable)
  • Supplier automation tools
  • Shipping/fulfillment apps

This gives you:

• One product catalog
• One inventory view
• One order dashboard
• Automated fulfillment routing
• Easier analytics and customer support

www.shopify.com

If your operation is marketplace-first

If most sales come from Amazon, eBay, Walmart, Etsy, etc., consider a dedicated multichannel management layer such as Linnworks or Sellbrite, with your store connected as another channel. www.capterra.comwww.guideflow.com

Key features to prioritize

For dropshipping specifically, look for:

1. Real-time inventory sync (avoid selling unavailable supplier stock)
2. Bulk listing management
3. Automated order forwarding to suppliers
4. SKU mapping
5. Price automation
6. Tracking number sync
7. Returns/refund workflow
8. Multi-currency and international support

If you are building a serious multi-channel dropshipping operation, I would generally start with Shopify as the commerce hub, then add a marketplace/order management layer only when order volume makes the extra complexity worthwhile. www.shopify.com

A useful next step would be choosing based on your scale:

• <100 orders/day: Shopify stack
• 100–1,000 orders/day: Shopify + multichannel management tool
• 1,000+/day: enterprise OMS/inventory platform

For dropshipping across your own store + social + marketplaces, I’d make Shopify the central hub and add a multichannel connector if you need broader marketplace coverage.

Best options

Why Shopify: it can connect your catalog to Amazon, Walmart, eBay and other marketplaces, while also selling through Facebook, Instagram, YouTube, TikTok and Google; Shopify positions the dashboard as the place to manage orders and fulfillment across channels. www.shopify.com

For dropshipping specifically, I'd strongly consider Shopify + Sellbrite. Sellbrite can bulk-list products, synchronize inventory, pull marketplace orders back into Shopify, and help fulfill those orders from one interface. Its Shopify integration explicitly treats Shopify as the central hub/source of truth. apps.shopify.com

LitCommerce is attractive if you want a wider assortment of channels. It supports Amazon, eBay, Etsy, Walmart, TikTok Shop, Google Shopping, Facebook Shops and others, with listing, inventory/price, and order synchronization. litcommerce.com

What I'd choose

If you're starting a dropshipping operation today:

Shopify → supplier/fulfillment app → Sellbrite → Amazon/eBay/Walmart
** ↘ Shopify sales channels → Instagram/Facebook/TikTok/Google**

That gives you one product catalog, one inventory source, and one order workflow, rather than maintaining separate listings and stock levels everywhere.
