Best marketplace management tools for Amazon and eBay sellers in 2026
Selling on more than one marketplace multiplies revenue potential and multiplies operational risk in roughly equal measure: the same item listed on Amazon and eBay at once will get oversold the first time stock runs low unless something keeps both listings in sync. Marketplace management tools exist to solve that specific problem, centralising listings, orders and stock across channels so a sale on one platform updates availability everywhere else automatically. This guide looks at three tools covering different seller sizes, from a low-cost small-seller option to enterprise-grade order orchestration.
Marketplace tools are one part of a wider e-commerce technology stack, and our e-commerce software buying guide covers how that stack fits together beyond just multi-channel listing.
Key takeaways
- Linnworks is a UK-built system priced by order volume It does not publish list prices; every quote is based on order volume rather than revenue, and it is worth a demo if you sell at meaningful scale.
- Sellbrite is the clearest published pricing for small sellers A genuine free plan and low-cost entry tier make it approachable, though Amazon FBA integration is a paid add-on.
- Extensiv Order Manager suits higher-volume, multi-warehouse operations Formerly known as Skubana, it is aimed at established sellers coordinating multiple warehouses or 3PLs, and pricing is quote-based rather than published.
Quick picks
Linnworks
Linnworks is a UK-founded order, inventory and multi-channel listing platform used by sellers running Amazon, eBay, and their own webstore alongside marketplaces, with particularly strong coverage of European and UK marketplaces alongside the usual Amazon and eBay integrations.
There is no published price list. Linnworks prices every account based on order volume rather than revenue or a flat per-seat fee, and a one-off, needs-based implementation fee applies for guided onboarding on top of the subscription. That makes it hard to compare on price alone without requesting a quote, which is a genuine inconvenience if you are trying to shortlist tools quickly, but it also means small and large sellers are not paying an identical rate for very different order volumes.
What justifies the quote-only pricing model in practice is depth: Linnworks handles complex listing rules across many marketplaces, warehouse-level stock allocation, and detailed shipping rule automation that goes well beyond basic multi-channel sync. For a UK or EU-based seller doing meaningful Amazon and eBay volume who wants a system built with European marketplace quirks in mind rather than adapted from a US-first product, it is worth the demo call even though you cannot get a number on the page.
Sellbrite
Sellbrite is a multi-channel listing and inventory sync tool, now owned by GoDaddy, aimed at smaller sellers who need to list the same products across Amazon, eBay, Walmart and their own Shopify or WooCommerce store without enterprise-level complexity or cost.
Pricing is the most transparent of the three here: Forever Free covers 30 orders a month at no cost, and the Pro tiers step up by order volume (100, 500 and 2,000 orders respectively) on annual billing rates published directly on Sellbrite's site in USD. Amazon FBA order integration is a separate paid add-on on paid plans, which is easy to miss when comparing the headline prices.
The strength here is straightforward: you can see exactly what you will pay before signing up, and the free plan is genuinely usable for a very small multi-channel seller rather than a crippled trial. The limitation is depth. Sellbrite handles listing and stock sync well but does not go as far into warehouse-level allocation or complex shipping rule automation as Linnworks or Extensiv, so sellers who outgrow basic multi-channel sync will eventually need to move to a more capable, and less transparently priced, platform.
Extensiv Order Manager
Extensiv Order Manager, the product formerly known as Skubana, is order and inventory management software built for established multi-channel sellers who operate across several warehouses or third-party logistics providers, not just several sales channels.
Like Linnworks, Extensiv does not publish a price list; access requires a sales conversation, and pricing is typically structured around order volume and the number of connected channels and warehouses rather than a flat subscription. That puts it firmly in enterprise-adjacent territory rather than a tool a very small seller would reach for first.
What it does well is order routing logic across multiple fulfilment locations, deciding automatically which warehouse or 3PL should fulfil a given order based on stock location and shipping cost, which is a genuinely different problem from simply keeping stock counts in sync across marketplaces. If you are a single-warehouse seller on Amazon and eBay, this is more infrastructure than you need. If you are coordinating stock across two or three fulfilment locations and want that routing decision automated rather than made manually by staff, it is a purpose-built answer to that specific problem, and the quote-based pricing reflects the more complex implementation involved.

How to choose a marketplace management tool
Coverage of the specific marketplaces you use matters more than the total number a tool claims to support.
A delay of even a few minutes between a sale and a stock update across channels can cause an oversell during a busy period.
Sellers fulfilling from more than one location need the system to decide, not just record, which location should fulfil each order.
Tools with published, order-volume-based pricing are easier to evaluate quickly, but the most capable enterprise tools are often quote-only.
Amazon has its own listing, repricing and account health requirements that generic multi-channel tools do not always handle well.
Frequently asked questions
Why do Linnworks and Extensiv not publish pricing?
Both price based on order volume, connected channels and, in Extensiv’s case, warehouse complexity, which varies enough between sellers that a flat published price would not reflect most customers’ actual cost. Sellbrite, aimed at smaller and more uniform sellers, publishes fixed tiers instead.
Do I need a marketplace management tool if I only sell on Amazon?
If you sell on Amazon exclusively, Amazon’s own Seller Central tools may cover your needs without a third-party platform. These tools earn their cost once you add a second channel, like eBay or your own store, and need stock to sync between them.
Does Amazon FBA integration cost extra?
On Sellbrite, yes, FBA order integration is a separate paid add-on on paid plans. Linnworks and Extensiv typically include FBA-related functionality as part of their quoted package rather than as a line-item add-on.
What is the difference between multi-channel sync and multi-warehouse routing?
Multi-channel sync keeps one stock count accurate across several sales channels. Multi-warehouse routing goes further, automatically deciding which physical location should fulfil a given order based on stock levels and shipping cost. Sellbrite focuses on the former; Linnworks and Extensiv Order Manager handle both.
Final verdict
- Linnworks: strong UK/EU marketplace depth, quote-based pricing only
- Sellbrite: clearest published pricing, less depth for complex operations
- Extensiv Order Manager: built for multi-warehouse order routing, quote-based pricing only
A small seller running Amazon and eBay from one location gets the clearest starting point from Sellbrite, since you can see the price before committing and the free plan is genuinely usable. A UK or EU-based seller with more complex marketplace needs should get a Linnworks quote before assuming a cheaper tool covers the same ground. Extensiv Order Manager is worth evaluating specifically once you are coordinating stock across more than one warehouse or 3PL, where its order routing logic solves a problem the other two do not.
