The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd suggest trying them - the right pick depends mostly on your size and how much operational complexity you have. **Start here for most small/mid shops** 1. **Sellbrite** - The easiest on-ramp. Syncs listings and inventory across Amazon, eBay, Walmart, Etsy, Shopify, BigCommerce and WooCommerce from one dashboard. Now owned by GoDaddy, and it's one of the very few with a genuinely usable free tier, so you can prove the workflow out before paying. Best if you want listing + inventory sync without heavy ops overhead. 2. **Shopify (+ Shopify POS)** - If you have a physical storefront, this is usually the backbone rather than a bolt-on tool. It gives you one product catalog for the shop floor, your own site, and marketplace/social channels via apps, and it has the deepest integration ecosystem of the POS options. Strongest online store, checkout, shipping and social-selling tooling of the mainstream POS platforms. 3. **Lightspeed Retail (X-Series)** - The better POS choice if you're inventory-heavy: advanced stock control, purchase ordering, supplier management, multi-location, and strong reporting. It syncs to Shopify for the ecommerce side, including multi-outlet → multi-location inventory mapping. I'd pick Lightspeed over Square for any complex retail operation; Square is fine if you're small and want simplicity. 4. **Veeqo** - Free shipping plan plus optional inventory automation across channels. Hard to beat on price if shipping and stock sync are your main pain points. **ShipStation** is the alternative if you specifically want rate shopping, label printing and fulfillment automation. **When you outgrow those** 5. **Linnworks** - Order and inventory automation at scale: warehouse routing, carrier rules, order automation across Amazon, eBay, Walmart, Shopify, Etsy, TikTok Shop and more. Pricing starts around $449/month. Pick it when inventory accuracy across multiple warehouses is the core problem. 6. **Descartes Sellercloud** - Built for high-volume sellers with messy backends: granular per-SKU channel control, warehouse management (via Skustack), multi-warehouse/FBA/3PL workflows. Around $1,349/month, no revenue share, onboarding included. 7. **ChannelEngine** - Best-in-class if marketplace *breadth* and product-data/feed control are the priority, especially across many global marketplaces. **Feedonomics** is the managed-service equivalent if you'd rather someone else own catalog syndication quality. 8. **Rithum (formerly ChannelAdvisor + CommerceHub)** - The enterprise default. Listings, inventory, orders, pricing and retail media in one orchestration layer. Typically $1,500-$2,500/month, over $6,000 at higher tiers. Genuinely not worth it for an independent shop - only consider it at large brand/retailer scale. **Two worth knowing about** 9. **Faire** - Not a management tool exactly, but if you're a brick-and-mortar retailer it now integrates directly with Shopify, Square, Clover and Lightspeed for wholesale ordering, reportedly lifting orders ~20%. 10. **3Dsellers** or **Nifty** - Niche but good if eBay is your primary channel. Nifty leans AI listing creation, crosslisting and bulk editing; 3Dsellers does high-volume automation and CSV editing while connecting eBay to Amazon, Walmart, Etsy and Shopify. **My short version:** if you're a physical shop adding marketplaces, run Shopify or Lightspeed as your system of record and add Sellbrite for marketplace listings. Only move to Linnworks or Sellercloud when order volume or warehouse complexity actually breaks that setup.
