The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd consider them: ## Start here (most stores) **1. Veeqo** - Amazon bought it and made it completely free, including discounted shipping rates. Inventory sync, order management, and shipping across Amazon, eBay, Walmart, Etsy, Shopify. For anything under ~$5M revenue, it's very hard to justify paying for a competitor before you've ruled this out. The catch is it's Amazon-owned, so you're deepening a dependency on them. **2. Sellbrite** - The other genuinely accessible option (now part of GoDaddy). Order-based pricing with a usable free tier, bidirectional inventory sync so you don't oversell. Best if you want listing creation + sync without operational heaviness, or if you'd rather not hand your data to Amazon. **3. ShipStation** - Not a full marketplace manager, but if your actual pain is labels, rate shopping, and fulfillment automation rather than listings, this is the narrower and better tool. Pairs well with either of the above. ## Mid-market, growing complexity **4. Linnworks** - The standard step up. Strong global marketplace automation, connects Amazon/eBay/Walmart/Etsy/TikTok Shop plus Shopify/WooCommerce/Magento. Real money though - Professional starts around $200/mo and tiers run into the thousands annually. Worth it when manual ops are costing you more than the license. **5. Extensiv Order Manager** - Pick this over Linnworks specifically if you're running multiple 3PLs or complex fulfillment routing. That's its differentiator. **6. Finale Inventory** - If your bottleneck is genuinely stock accuracy across warehouses rather than channel listings, this is inventory-first and better at it than the generalists. ## Enterprise **7. ChannelEngine** - Best-in-class for deep product data control across a lot of global marketplaces. The one I'd name for European/international marketplace expansion. **8. Rithum (formerly ChannelAdvisor)** - Listings + retail media + dropship in one platform. Only makes sense at $50M+ GMV: pricing starts around $2K/mo, runs $60K-$150K+ annually, involves GMV revenue share and multi-year contracts. Reviewers consistently flag it as opaque and hard to exit - negotiate the exit terms before you sign. ## Amazon-specific add-ons These sit alongside, not instead of, the above: - **Sellerboard** - profit and P&L tracking; full analytics on every plan, unlike competitors that gate it. - **Helium 10** or **Jungle Scout** - product research and keywords. Jungle Scout is cheaper (~$29-49/mo); Helium 10 is broader but tops out around $359/mo. Note Helium 10 has no built-in repricer. - **Seller Snap** or **BQool** - repricing, if you compete on shared listings. **My actual advice:** start with Veeqo or Sellbrite, and only move to Linnworks when you can name the specific thing they can't do. Most stores overbuy here.
