The answer, as recorded

## Where I'd start **Shopify** - the default recommendation for most people. Easiest path from zero to selling, biggest app ecosystem, best-in-class checkout, and it scales from a side hustle to eight figures without a replatform. Plans run ~$39-$399/mo. The catch: apps add up (a typical store runs $100-$300/mo on top), and you pay extra transaction fees if you don't use Shopify Payments. **WooCommerce** - best if you already have a WordPress site or want to own your stack. Free plugin, no revenue cut, infinitely customizable. Real cost is hosting ($25-$100/mo) plus your time or a developer's - it's the "you're the sysadmin now" option. **BigCommerce** - the strongest pick for large or complex catalogs, lots of variants/SKUs, or B2B. Zero transaction fees on every plan and more built in out of the box, so you install fewer apps. Watch the 2026 plan changes: revenue thresholds dropped (old $50K Standard cap is now a $30K Core cap), so growth can bump you to a pricier tier sooner. ## If the store is part of a broader site **Squarespace** - best design quality per unit of effort, unlimited products even on the entry plan (~$12.50/mo). Ideal for brands where the site matters as much as the catalog: studios, restaurants, small apparel labels. **Wix** - fastest to launch, 2,000+ templates, solid POS and omnichannel selling. Slightly weaker as a pure store than Squarespace, but better if you want the whole site built in an afternoon. Neither is ecommerce-first - if selling *is* the business, go Shopify or BigCommerce. **Square Online** - the one I'd name for an existing brick-and-mortar shop. If you already take payments on Square, the online store inherits your inventory and catalog for free. Not worth choosing if you're online-only. ## Developer-led / enterprise **Medusa** - the open-source headless pick right now. Node/TypeScript/Postgres, fastest-growing project in the category (30k+ GitHub stars), credible up to roughly $20M GMV *if* you have a team that can operate it. Don't choose this without engineers. **Adobe Commerce (Magento) / commercetools / Salesforce Commerce Cloud** - only for genuine enterprise: complex B2B rules, multi-region, deep ERP integration. Expensive and slow to implement; no reason to be here otherwise. **Shopware** is the equivalent if you're European B2B. ## Short version Solo or small team, want to sell today → **Shopify**. Already on WordPress or allergic to platform fees → **WooCommerce**. Thousands of SKUs or B2B → **BigCommerce**. Design-forward brand site → **Squarespace**. Existing retail store → **Square Online**. Engineering team and custom requirements → **Medusa**.
