The Complexity Gap

How Our Marketplace Integration Software Ends Overselling

When your Shopify store doesn't talk to Amazon or your warehouse or 3PL, overselling becomes inevitable. Cin7 eliminates the guessing game by unifying every order and inventory movement in real time.

Here's how it works. Every channel draws from the same live stock count in Cin7. When a unit sells anywhere, we update available stock everywhere else, so your last pair of boots can't sell twice.

Real-time sync, zero overselling: When an item sells on Amazon, your stock levels instantly update across your other channels.
Unified order management: View, process, and track orders from every corner of your business in one master dashboard.
Channel-specific reporting: Stop guessing where you're most profitable. Drill down into margins and fees for each channel to optimize your sales mix.

Cin7 Handles It All

Multichannel selling looks different for every brand. Whether you're managing apparel variants or food-grade traceability, Cin7 gives you the specialized tools to manage diverse product catalogs across global markets.

Selling one product in five sizes on four channels? That's 20 listings to keep straight, and Cin7 ties every one of them to a single stock count.

CPG: Track serial numbers and batches across wholesale and D2C channels for total compliance.
Manufacturing: Sync production schedules with real-time demand across every channel so you're never overbuilding one SKU or scrambling to fulfill another.
Furniture: Handle oversized shipping and kitting logic for complex, multi-component bundles.
Sell Without Limits

Built for Every Channel

Every channel has its own rules, fees, and quirks. Cin7 keeps them all working from one stock count, so adding a new channel doesn't mean adding a new headache.

E-commerce & Marketplace Integrations

Easily connect to Shopify, BigCommerce, Amazon, and eBay. Manage your listings, sync stock, and automate high-volume order processing all in one place.

Wholesale & Big Box Retail

Manage your B2C and B2B sales in one place. Cin7 gives you EDI, a B2B sales portal, and bulk order management alongside your direct sales. All orders draw from the same live stock pool, so nobody sells what's already spoken for.

Brick & Mortar + POS

Your physical store shouldn't be an island. Integrate your existing POS so your in-store sales immediately reflect in your online availability.

Smart Order Fulfillment

Automatically route orders to the closest location. You'll love the lower shipping costs and built-in shipping integrations, and your customers will love the quick delivery times.

How Marketplace Integration Works in Cin7

Getting every channel in sync doesn't take a computer science degree. Here's the whole flow in four steps.

Once you're set up, the day-to-day gets quiet in the best way. Your team stops copying orders between tabs and spends that time on growth instead.

1. Connect your channels. Plug in Shopify, Amazon, eBay, BigCommerce, WooCommerce, and your POS. They all connect to the same Cin7 account.
2. Map your products once. Match each channel listing to one product, SKU, and variant in Cin7. Sizes and colors stay straight everywhere.
3. Sync stock and orders in real time. Orders from every channel land in one place with multichannel order management. Stock updates across channels as each sale happens.
4. Route, fulfill, and update. Each order goes to the best location: your warehouse, a 3PL partner through 3PL Connect, or Amazon FBA.

Multichannel vs. Omnichannel Inventory Management

Multichannel selling means you sell in many places at once. Omnichannel goes a step further by connecting your channels so stock, orders, and the customer experience stay consistent everywhere.

Cin7 handles both, because omnichannel inventory management starts with multichannel stock you can trust.

Marketplace Integration & Multichannel Selling FAQs

What is marketplace integration software?

It's software that connects your online marketplaces, e-commerce stores, and other sales channels to one central system. It syncs stock, listings, and orders between them, so you can manage every channel from one place. Cin7 does this as part of a full IMS, alongside purchasing, fulfillment, and reporting.

What is multichannel inventory management?

Multichannel inventory management synchronizes stock levels across all sales channels, including e-commerce stores, marketplaces like Amazon, wholesale accounts, and physical retail locations. It does this in real time from a single platform.

How does Cin7 prevent overselling across channels?

Cin7 updates inventory counts instantly when a sale occurs on any channel. Stock levels reflect across Shopify, Amazon, eBay, POS systems, and other platforms simultaneously to eliminate overselling.

Can Cin7 integrate with existing POS systems?

Yes, Cin7 integrates with existing point-of-sale systems to ensure in-store sales immediately update online inventory availability across all connected channels.

What types of businesses use Cin7?

Cin7 serves brands in CPG, manufacturing, furniture, apparel, and other industries that sell through multiple channels including e-commerce, wholesale, marketplaces, and brick-and-mortar stores.

Does Cin7 support EDI for big-box retailers?

Yes, Cin7 provides EDI capabilities for big-box retail partnerships alongside B2B sales portals and bulk order management for wholesale operations.

How does Cin7 handle order fulfillment across multiple locations?

Cin7 automatically routes orders to the optimal fulfillment location, whether your warehouse, a 3PL partner, or Amazon FBA. Routing is based on proximity to reduce shipping costs and delivery times.

What accounting software does Cin7 integrate with?

Cin7 integrates deeply with Xero and QuickBooks, ensuring financial data flows automatically without manual exports or duplicate data entry.

Can Cin7 track product variants and batches?

Yes, Cin7 tracks serial numbers, batches, and product variants across all channels, supporting compliance requirements for food-grade traceability and apparel size/color management.

What is the best marketplace integration software?

Honestly, it depends on where you sell and whether wholesale is part of your mix. The right fit gives you two-way, real-time sync, connects to the marketplaces you actually use, and runs every channel from one stock pool. Cin7 is an IMS built to do exactly that, for DTC and B2B alike.

How do you manage inventory across multiple sales channels?

Start with one central stock record instead of a separate count in each channel. Connect every channel to it, so a sale anywhere updates stock everywhere in real time. Then let each order route to the location best placed to ship it. No more updating five dashboards after every sale!

Which marketplaces can Cin7 connect to?

We connect natively to Amazon, eBay, Walmart, and Faire, plus e-commerce platforms like Shopify, BigCommerce, and WooCommerce. Your POS plugs in too, so in-store sales count against the same stock. Need something else? You've got 700+ app partners to pick from in our integrations directory.

How do I choose inventory management software for multichannel selling?

Start by listing every channel, warehouse, and app you use today, plus what you plan to add. Then check each tool against that list: channels covered, sync speed, variant and SKU mapping, and support for both B2B and DTC. Make sure it connects to your accounting software and 3PLs, with room to grow. A tool that fits today's list but not next year's is a short-term fix.

Can I manage wholesale (B2B) and direct-to-consumer orders in one platform?

Yes! Cin7 runs B2B and DTC orders from the same live stock, so a wholesale order can't claim units you've already sold online. Wholesale customers can order through our B2B Portal, and big-box retailers can send orders by EDI. Everything lands in one dashboard for you to process.

Join 8,500+ brands that have traded channel chaos for unified commerce performance. Real-time stock, one order dashboard, and fulfillment that routes itself. That's multichannel inventory management software that keeps up with you!
