The answer, as recorded

Here's how I'd actually pick, roughly in the order I'd suggest trying them - the right answer depends mostly on your order volume: **Starting out / small catalog (under ~$1M)** 1. **Sellbrite** (GoDaddy) - the easiest on-ramp. Lists to Amazon, eBay, Walmart, Etsy, Shopify, BigCommerce, WooCommerce with centralized inventory and order sync, and it's one of the very few with a genuinely usable free tier. Start here unless you have a specific reason not to. 2. **Ordoro** - if shipping is as much your pain as listing. Combines inventory sync, purchase orders, supplier tracking, and label generation across Etsy/Shopify/Amazon/eBay/BigCommerce. 3. **Veeqo** - free from Amazon, with discounted shipping rates. Covers Amazon (incl. FBA), eBay, Etsy, Walmart, TikTok Shop. Hard to beat on price; the tradeoff is you're deeper into Amazon's ecosystem. 4. **Sumtracker** - narrow but does the one thing well: two-way stock sync across Shopify/Amazon/eBay/Etsy/Walmart with multi-location and 3PL support. Good if you only need to stop overselling. **Growing / mid-market (~$5M-$50M)** 5. **Linnworks** - the workhorse for high-volume, multi-warehouse operators. Quote-based, roughly $449/mo entry, landing around $14K-$25K/yr at $10M revenue. Strongest on pick/pack/carrier label workflows. 6. **Zentail** - better than Linnworks if you're a first-party brand or private-label seller. Its SMART Types catalog mapping automates listing data across Amazon, Walmart, and Target Plus. Runs about $18K-$36K/yr at $10M. 7. **ChannelEngine** - the one I'd name for Europe and marketplace breadth. Real-time inventory sync and automated listing distribution at scale; the right pick if marketplace expansion is the strategy rather than a side channel. 8. **Feedonomics** - not a full management suite, but if your problem is bad product data killing listings, this is the managed feed platform to buy. **Enterprise** 9. **Rithum** (formerly ChannelAdvisor) - deepest global marketplace coverage plus retail media. Costs 2-3x the mid-market tools ($60K-$150K+ at $50M revenue), which only pays off at real scale. 10. **NetSuite** or **SellerCloud** - if you need finance, orders, and inventory governed in one system rather than a marketplace tool bolted onto an ERP. Practical advice: don't over-buy. Most sellers under $1M are well served by Sellbrite or Veeqo and regret paying for Linnworks-tier tooling. The migration up is annoying but far cheaper than paying enterprise fees for two years first.
