1. Shopify mentioned
   Shopify Marketplace Connect (formerly Codisto) - If your store is already on Shopify, start here before paying for anything else.

5. BigCommerce mentioned

13. Rithum mentioned

The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd suggest you evaluate them - the right answer depends mostly on your order volume, since this category prices by tier and the enterprise tools are genuinely bad buys for small sellers. ## If you're small or just starting multichannel **1. Shopify Marketplace Connect (formerly Codisto)** - If your store is already on Shopify, start here before paying for anything else. It's free to install, keeps Shopify as your source of truth, and pushes listings/inventory/orders to Amazon, eBay, Walmart, and Etsy. Not the most powerful tool, but the price-to-value is unbeatable and it rules out the need for a third-party tool for a lot of people. **2. Sellbrite** - The best genuinely cheap standalone option. Free for up to 30 marketplace orders/month with unlimited SKUs, users, and channels; Shopify plans at $19/mo (100 orders) and $59/mo (500 orders), scaling to ~$679/mo. Bulk listing creation across Amazon, eBay, Walmart, Etsy, Shopify, BigCommerce. Caveat: inventory syncs every ~2 hours, not real-time, so it's risky if you're selling thin stock across many channels. **3. Nembol or LitCommerce** - Worth a look as cheaper, lighter listing-sync alternatives if Sellbrite's sync interval or channel list doesn't fit. Both are in the $29-100/mo range and aimed at resellers and handmade/Etsy-heavy sellers. ## If you're mid-market (roughly $1M-$20M GMV) **4. CedCommerce** - Best value for breadth of connectors. Per-marketplace apps for Amazon, Walmart, eBay, Etsy, TikTok Shop and dozens more, usually a few hundred dollars a month rather than four figures. Good if you want to add one channel at a time instead of buying a whole platform. **5. Zentail** - The one built specifically for marketplace sellers rather than retrofitted from an inventory tool. Its "SMART Types" catalog model handles the painful part - mapping one product record to each marketplace's wildly different category attributes. Strong choice if your catalog is large and listing quality is your bottleneck. **6. Linnworks** - Pick this if your real problem is the warehouse, not the listings. 100+ channels, strong order routing, carrier automation, and fulfillment logic. From ~$449/mo, quote-based, with typical onboarding fees. No revenue-share pricing, which matters a lot as you scale. **7. ChannelEngine** - The one I'd name for international expansion. Very broad European and global marketplace coverage with pricing/promotion controls and product syndication; built as an orchestration layer for teams running dozens of marketplaces across countries. ## Enterprise **8. Mirakl** - Different category, worth naming because people conflate it: this is for *operating* your own marketplace (letting third-party sellers list on your site), not for selling on others'. If that's the question, it's the clear leader. **9. Rithum (formerly ChannelAdvisor + CommerceHub)** - The incumbent, and only sensible above roughly $50M GMV where you want marketplace listings plus retail media advertising in one contract. Expect ~$2,000+/mo base, a 1.3-3.0% take rate on GMV, per-channel integration fees, and multi-year terms. Prices rose notably after the merger - I'd only sign if the retail media side is what you're buying. **10. Sellercloud (Descartes)** - The deep-operations choice at the top end: from around $1,349/mo, no revenue share, onboarding included. More of an ERP-grade system than a listing tool; strong if you need custom workflows and warehouse depth. **The main thing I'd flag:** avoid buying at a tier above your volume. The jump from Sellbrite-class tools to Linnworks/Sellercloud-class tools is roughly 10-30x in cost, and the enterprise vendors' GMV take-rates mean your bill grows faster than your margin. Also check how often each tool syncs inventory - oversell penalties on Amazon and Walmart cost more in suspended-account risk than the software savings are worth.
