About Linnworks
Linnworks is the multichannel commerce platform that helps retailers grow sustainably. It connects operations across 100+ sales channels, bringing inventory, order, and warehouse management into one platform. More than 4,000 retailers run on Linnworks, processing $18B in GMV and 250M+ orders a year — because growth is never just a number.
Chapter 1
What is Mirakl?
Mirakl isn’t a marketplace. It’s the technology behind more than 450 of them. Retailers who want to run their own marketplace, letting outside sellers list products alongside their own range, often build it on Mirakl’s platform rather than creating the underlying seller management, order routing, and payment infrastructure from scratch.
Examples include B&Q Marketplace, Best Buy, CDiscount, Decathlon, FNAC, Macy’s, Mountain Warehouse, Secret Sales, and Target Plus, among hundreds of others spanning fashion, home, outdoor, sport, and general retail.
For a seller, that shared technology matters more than it might seem. Each Mirakl-powered marketplace is still a separate business with its own application process, requirements, and fees. But because they share the same underlying platform, a single integration, like the one Linnworks offers, can connect to any of them.
Chapter 2
Why sell on Mirakl-powered marketplaces?
Mirakl’s technology powers more than 450 marketplaces worldwide, including well-known names across nearly every category.
More than 100,000 sellers already trade through the network, and Mirakl-powered marketplaces processed over $11 billion in combined GMV in 2024.Normally, joining a new marketplace means answering two questions at once: is the audience worth reaching, and is it worth the work of building a new integration to get there? Connecting through Mirakl removes the second question. Once that connection is set up, the technical work needed for any Mirakl-powered marketplace is largely already done. Adding a new one becomes a business decision, not a development project.
Linnworks customers have used this route to reach a real range of retailers. Sellers have driven real revenue growth on marketplaces like Decathlon and Secret Sales through the Mirakl connector. Tamworth Camping, a UK camping and outdoor equipment retailer, used the same route to expand onto Mountain Warehouse on a Linnworks team recommendation.
Chapter 3
Eligibility and requirements
There’s no single eligibility bar for “Mirakl,” because Mirakl doesn’t run any of the marketplaces itself. Each retailer sets its own criteria for the marketplace it operates. That said, a few patterns show up repeatedly across Mirakl-powered marketplaces:
- Most are invitation-only or application-based rather than open to any seller who signs up
- Business registration in the relevant country or region is typically required
- Product compliance and quality checks are common, often including proof of brand authorization
- Delivery and customer service standards are usually enforced, with consequences for repeated underperformance
Beyond that, requirements differ from retailer to retailer. Applying to a new Mirakl-powered marketplace means checking that specific retailer’s own application process, not a single unified “Mirakl seller” signup.
Chapter 4
Fees and commission
Mirakl doesn’t charge sellers directly. It licenses its technology to the retailers running each marketplace, and those retailers set their own commission structures for third-party sellers.
That means fees can vary a lot between two Mirakl-powered marketplaces. The good news is, Mirakl doesn’t charge any extra fee on top of whatever the retailer charges.
Chapter 5
How to get started
- Find a fit. Not every one of the 450+ Mirakl-powered marketplaces will be relevant. Focus on the retailers whose audience and category match what you sell.
- Apply. There’s no single “Mirakl application.” Each marketplace runs its own process, at its own pace.
- Get accepted. Approval timelines vary, from days to months, depending on how selective that particular marketplace is.
- Connect via Linnworks. Once accepted anywhere in the Mirakl network, add a Mirakl channel from within Linnworks. This handles the technical connection without needing a separate build for each new marketplace.
- List, sync, and fulfill. Manage stock, orders, and listings for every connected Mirakl marketplace alongside every other channel.
- Expand. Apply to additional Mirakl-powered marketplaces as they make sense, reusing the same underlying connection each time.
Chapter 6
Challenges to plan for
Each marketplace is still its own relationship
Sharing a technology platform doesn’t mean sharing an application, a fee structure, or a set of expectations. Getting into multiple Mirakl-powered marketplaces still means managing multiple separate retailer relationships, each with its own rules.
The number of options can be its own problem
With 450+ marketplaces to choose from, picking the right ones matters more than trying to be everywhere at once. A handful of well-matched marketplaces will usually outperform a scattershot approach across many.
Requirements aren’t lighter just because it’s Mirakl
Retailers running Mirakl-powered marketplaces often use the same quality, compliance, and performance bars they’d apply to any third-party seller relationship. The shared technology doesn’t mean a lower bar to clear.
Another channel means another storefront to keep accurate
The same challenge shows up on every marketplace: another set of stock levels, listings, and orders to keep in sync as the business grows, once for every Mirakl-powered marketplace a seller joins. Tamworth Camping found that a single unexpectedly busy day on just one Mirakl-connected marketplace was enough to overwhelm their team before automation was in place.
Chapter 7
How Linnworks helps you manage Mirakl-powered marketplaces
Linnworks connects to Mirakl-powered marketplaces through a single integration, built on a third-party app called Fulfillin, rather than requiring a custom connection for each one individually.
A listing built once on Linnworks can go live on any connected Mirakl marketplace without rebuilding it for each one, and stock and pricing update across all of them at the same time. Inventory management is covered, too.
A sale on one marketplace is reflected everywhere else within moments, so overselling stays rare even as the number of connected marketplaces grows. Every order, whichever Mirakl marketplace it came from, lands in the same dashboard as orders from every other channel a seller uses, ready to pick, pack, and dispatch.
For a seller already connected to one Mirakl-powered marketplace, adding a second or third, once accepted, is a matter of extending the same connection rather than starting from scratch.
What multichannel growth actually looks like with Temu and Linnworks.
“Without centralized systems or automation, scaling further risked creating bottlenecks across warehouse and fulfillment. We saw Linnworks as a long-term solution that could support our growth across multiple channels.”
