The answer, as recorded

## Marketplace management tools worth naming The right pick depends almost entirely on your order volume, so here's how I'd order them by where you sit: **If you're small (under ~2,000 orders/month)** 1. **Sellbrite** - My default recommendation for most small sellers. It syncs listings, inventory and orders across Amazon, eBay, Walmart, Etsy, Shopify and BigCommerce, and it's owned by GoDaddy so it's stable. Free forever up to 30 orders/month, then $29 (100 orders), $79 (500), $179 (2,000). Inventory decrementing across channels is its genuine strength - items get pulled from other marketplaces within seconds of selling. 2. **Veeqo** - Free, and owned by Amazon. Best if Amazon is the bulk of your revenue with secondary channels, because it bundles Amazon account health protection you can't get from any third party. Shipping plus inventory in one. 3. **LitCommerce** - The budget option. Connects to 20+ marketplaces, free tier covers 20 listings. Good for testing whether multichannel is even worth it for you before paying anyone. 4. **ShipStation** - Worth it over Veeqo only if you need breadth of carriers (40+ vs Veeqo's handful) or you sell on less common niche marketplaces. From $14.99/mo, and it gets expensive as you scale. **If you're mid-market (roughly $1M-$20M)** 5. **ChannelEngine** - The strongest option for marketplace *breadth*, especially international. 1,300+ channels. Quote-based, from around €300/month, sometimes with ~1.3% revenue share - watch that clause. 6. **Linnworks** - Pick this over ChannelEngine if your pain is operational rather than channel expansion: multi-warehouse inventory, order routing, complex automation rules. From about $449/month, quote-based. 7. **Feedonomics** - Not a full management platform, but if your actual problem is messy product data getting rejected by marketplaces, this is the managed feed service that fixes it. Often used *alongside* one of the above. **If you're enterprise** 8. **Rithum** (formerly ChannelAdvisor, merged with CommerceHub) - Deepest marketplace and warehouse integrations, plus retail media management. Custom pricing that scales with order volume. Honestly, only worth the cost and implementation lift above roughly $20M GMV. **One caution:** every mid-market and enterprise option here is quote-only, which means pricing is negotiable and the published figures above are directional. Get two quotes before signing, and read the revenue-share terms carefully - a 1.3% cut on GMV can dwarf the subscription fee at scale.
