Shopify is the default answer for most ecommerce stores because it's genuinely good at almost everything and rarely bad at anything. The admin is polished, the app ecosystem is unmatched (17,000+ apps handle almost every edge case), the checkout converts well, and the platform scales from a Basic $39/month store to Plus tier at $2,300/month without a full migration. For anyone who doesn't have a specific reason to pick something else, Shopify is the pragmatic pick — and the pragmatic pick is often the right pick.

The trade-offs to know about: Shopify charges 0.5-2% platform transaction fees on top of card processing unless you use Shopify Payments (which forces you to use their processor). The apps ecosystem is powerful but expensive — a $39/month store often becomes $200-400/month once you add the apps needed for real operations. And custom checkout logic is limited unless you're on Shopify Plus (which does support Checkout Extensibility). For most SMB and scaling stores, none of these are dealbreakers.

BigCommerce is the strongest alternative to Shopify for merchants who care about total cost of ownership. The headline advantage: zero platform transaction fees on any payment gateway. Shopify charges 0.5-2% on every sale unless you use Shopify Payments. For a store processing $100,000/month, that's $6,000-24,000 per year in savings — enough to pay for the plan several times over. BigCommerce also ships with deeper out-of-box features: product ratings, real-time shipping quotes, abandoned cart recovery, faceted search, custom price lists, and multi-currency selling. On Shopify, several of these require paid apps.

The trade-off: smaller ecosystem. Fewer apps, fewer prebuilt themes, less community content, and less brand recognition when hiring. If you value ecosystem depth and everyone-knows-Shopify familiarity, Shopify wins. If you care about not paying platform transaction fees and want more depth without add-ons, BigCommerce wins. For high-volume stores, the transaction fee math often decides it.

WooCommerce is the plugin that adds full ecommerce functionality to any WordPress site. Free to install, no platform fees, no per-transaction commission — but you're responsible for hosting, security, updates, and everything WordPress requires. For merchants already deep in the WordPress ecosystem, WooCommerce is the pragmatic choice: you keep your existing site, add commerce, and get access to the largest plugin marketplace in the world (100,000+ plugins). It powers roughly 28% of all online stores globally.

The trade-offs are real. WooCommerce is genuinely free, but running it in production requires managed hosting ($30-100+/month), premium plugins for anything serious, and either technical skill or a developer on call. For serious ecommerce, most operators use managed WooCommerce hosting which starts around $15-30/month at the entry level. Total cost of ownership ends up similar to Shopify for most stores — you're paying with time and complexity instead of platform fees.

Wix is what you pick when you want an all-in-one website (portfolio, blog, booking, ecommerce) rather than a commerce-first platform. The drag-and-drop builder is genuinely good, the templates are professional, and setup takes hours instead of days. Zero platform transaction fees on all commerce plans (a nice surprise). Best fit: small stores where the "store" is one part of a broader website, service businesses adding light ecommerce, or founders who value design flexibility over commerce depth.

The trade-off: Wix isn't purpose-built for ecommerce the way Shopify is. Multichannel selling is weaker, the checkout has fewer conversion optimizations, and the growth ceiling comes sooner. For a store doing under $500K/year, Wix is genuinely competitive and often more affordable. For anything approaching $1M+, most operators migrate to Shopify or BigCommerce for the deeper feature set.

Squarespace is what design-conscious founders pick when they can't stand the "another Shopify store" look. The templates are the most polished in the category — every one of them ships as a genuinely beautiful starting point, not something you'll spend a weekend customizing to look decent. For service businesses, portfolios with light selling, digital product creators, and design-forward brands, Squarespace is often the cleanest fit. Commerce transaction fees drop as low as 2% on the Commerce Basic tier and 0% for digital products and memberships on higher tiers.

The trade-off: commerce depth. Squarespace doesn't do multi-currency, has weaker multichannel selling than Shopify or BigCommerce, and the app ecosystem is smaller. For product-heavy stores planning to scale past $500K-1M/year, you'll likely outgrow it. For brands where design matters more than commerce depth and you're operating in a single currency, it's genuinely excellent.

Shopify Plus is the same platform you already know, upgraded for stores that have outgrown the standard plans. What you actually get for $2,300+/month: significantly higher API rate limits, custom checkout via Shopify Functions and Checkout Extensibility, up to 10 international storefronts included, dedicated account management, priority support, and lower Shopify Payments processing rates. Most DTC brands doing $3M+ per year graduate to Plus for the combination of custom checkout capability and the transaction fee savings on Shopify Payments (which more than covers the plan cost at their volume).

The trade-off is the price and what you don't get. Plus isn't a fundamentally different platform — it's Shopify with extras. If Shopify doesn't fit your needs, Plus won't fix that. What Plus is genuinely good for: fast-scaling brands where the standard Shopify Advanced plan hits its ceiling (API rate limits, transaction fees eating into margins, need for real checkout customization).

Square Online exists for one specific customer: physical retailers, restaurants, and service businesses who already use Square for in-person payments and want to add online sales without a separate system. The integration is genuinely tight — inventory, orders, customers, and payments all sync between your physical POS and online store automatically. The free tier is real (not a trial), with paid tiers at $29 and $79 for additional features. For local businesses running a restaurant, boutique, or salon that want online ordering, Square Online is often the fastest and cheapest path.

The trade-off: Square Online isn't built for pure-DTC ecommerce. The store templates are limited, the app ecosystem is small, and the platform assumes you have a physical business as your primary operation. For online-first brands, Shopify or BigCommerce will be dramatically better. For retail-first businesses adding online: Square Online is genuinely the best-fit option.

Ecwid is a genuinely useful in-between option: a hosted ecommerce platform designed to embed into any existing website (WordPress, Wix, Squarespace, static HTML — anything). If you already have a website you like and don't want to migrate, Ecwid lets you add a full commerce layer with cart, checkout, and product management without rebuilding anything. Free plan supports up to 5 products; paid plans scale up. Owned by Lightspeed since 2021, so POS integration is native.

The trade-off: Ecwid is limited compared to dedicated commerce platforms. Fewer apps, less customization, and the growth ceiling is lower than Shopify or BigCommerce. It shines specifically as an add-on to an existing site, not as a primary commerce platform for a serious store. For a service business selling a small product line alongside their main offering, it's often the right answer.

BigCartel is the platform artists, illustrators, indie brands, and small creators have quietly loved for over 20 years. Free for up to 5 products, $12/month for 50 products, $22/month for 500. Zero platform transaction fees. Templates are minimal (which for creator brands is often exactly right). No app ecosystem, no complex features — just an inexpensive way to sell your work online without giving Shopify $50/month you don't have. For makers, band merch stores, small print shops, and hobby brands, BigCartel is often the cleanest fit.

The trade-off: no growth ceiling worth mentioning. BigCartel isn't going to scale you to $1M/year. It's not trying to. If you outgrow it, you migrate to Shopify or WooCommerce like everyone else. But for the entry-level creator segment where a $12/month platform beats a $200/month all-in Shopify setup, BigCartel is the honest answer.

Adobe Commerce (formerly Magento) sits at the enterprise end of the market — a PHP-based platform with unmatched flexibility for complex catalogs, sophisticated B2B, and deep customization. Adidas, Ford, Land Rover, and other global brands run on it. The trade-offs are meaningful: implementation typically requires a specialized agency and 6-12 months of engineering work, ongoing operational cost is significant (developers, hosting, integrations), and the platform is genuinely difficult to work with compared to modern alternatives.

Adobe Commerce is the right answer when: your catalog complexity or B2B requirements genuinely exceed what Shopify Plus or BigCommerce Enterprise can express, you have dedicated technical resources or an agency relationship, and you're operating at a scale where the enterprise license makes financial sense ($10M+/year typically). For anything smaller or simpler, this platform is overkill — pick Shopify Plus or BigCommerce Enterprise instead.
