Your platform choice decides more than your storefront. It sets your monthly costs, your checkout conversion rate, and whether AI shopping assistants can even find your products.
Here’s the short answer. Shopify fits most new stores. WooCommerce wins for content-heavy brands with technical help. BigCommerce suits large catalogs and B2B. Wix and Squarespace work for small, design-led shops. Adobe Commerce serves enterprises with developers on payroll.
The long answer, with real 2026 pricing and a cost example you can copy, is below.
Quick Comparison: 7 Best eCommerce Platforms at a Glance
| Platform | Starting Price (Annual) | Platform Transaction Fee | Best For |
| Shopify | $29/mo | 0% with Shopify Payments; 2% on Basic with third-party gateways | Most new and growing stores |
| WooCommerce | Free plugin + hosting ($25+/mo) | 0% | Content-driven brands on WordPress |
| BigCommerce | $29/mo | 0% on every plan | Large catalogs, B2B sellers |
| Wix | $29/mo | 0% | Simple stores under 500 products |
| Squarespace | $17/mo (Core) | 0% on Commerce plans; 3% on Business | Design-first small shops |
| Adobe Commerce | $22,000+/yr (cloud) | 0% | Enterprises with dev teams |
| Shopify Plus | $2,300+/mo | 0.2% third-party | Brands past $1M-$2M in annual sales |
Payment processing fees (roughly 2.2% to 2.9% + $0.30 per card transaction) apply everywhere. The table shows what the platform itself takes on top.
Shopify: The Fastest Path From Idea to First Sale
Shopify remains the default for a reason: it ships the shortest route from idea to live store. Hosting, security, PCI compliance, and updates are handled.
The 2026 lineup runs five tiers: Starter at $5/month (checkout links only, no storefront), Basic at $39/month ($29 annual), Grow at $105/month ($79 annual), Advanced at $399/month ($299 annual), and Plus from $2,300/month on a three-year term. Annual billing cuts 25% off the core plans.
Two details trip people up. First, Basic includes zero staff accounts; the owner is the only login. Second, if you skip Shopify Payments for a third-party gateway like PayPal, Shopify adds its own surcharge: 2% on Basic, 1% on Grow, 0.6% on Advanced.
What you get in return is the strongest app ecosystem in commerce (8,000+ apps), Shopify Magic for AI-generated product copy, and Agentic Storefronts that syndicate your catalog to ChatGPT, Perplexity, and Microsoft Copilot at once. Shopify reported AI-driven traffic to its stores grew 8x year over year in Q1 2026, with orders from AI search up nearly 13x.
Pick Shopify if: you want predictable costs, fast launch, and built-in AI distribution. Skip it if: your growth engine is editorial SEO content, or app subscription creep worries you.
WooCommerce: Full Ownership for Content-Led Brands
WooCommerce is a free, open-source plugin that turns WordPress into a store. Since WordPress powers roughly 43% of all websites, WooCommerce is the most-installed eCommerce solution on earth by volume.
Free is the license, not the bill. A production store needs quality hosting ($25 to $150/month), a premium theme, paid extensions for advanced features, and someone to run updates and security. Budget honestly and the total often lands near a Shopify subscription. Past $2M in annual sales, industry estimates put a well-maintained open-source stack at $40,000 to $150,000 per year including developer time.
The payoff is control. You own your data, your URL structure, and your checkout. No platform transaction fees, ever. And because your store lives inside the best content management system available, WooCommerce is unbeatable when blog posts, buying guides, and organic search drive your revenue.
One honest caveat: performance degrades noticeably above 5,000 to 10,000 products unless your hosting and caching are dialed in.
Pick WooCommerce if: content marketing is your primary acquisition channel and you have technical support. Skip it if: you want zero maintenance responsibility.
BigCommerce: Built-In Muscle for Big Catalogs and B2B
BigCommerce mirrors Shopify’s pricing almost exactly (Standard $39/month, Plus $105, Pro $399, all 25% cheaper annually) but charges zero platform transaction fees on every plan and with any of its 65+ payment providers.
The platform bakes in features Shopify sells through apps: faceted search, multi-currency across 140+ currencies, unlimited staff accounts, and native B2B tools like customer groups, bulk pricing, and quote management. A Forrester study found BigCommerce customers see a 211% ROI by year three.
Watch the revenue thresholds, though. Standard caps at $50,000 in annual online sales, Plus at $150,000, Pro at $400,000. Cross a cap and you’re auto-upgraded to the next tier, which makes the “cheap” entry price misleading for fast growers.
Pick BigCommerce if: you run a large catalog, sell B2B, or refuse to pay platform fees. Skip it if: you want the most polished admin experience or the deepest app market.
Wix and Squarespace: Simple, Beautiful, and Fine at Small Scale
Both are website builders with commerce bolted on, and both have improved sharply.
Wix eCommerce starts on the Core plan at $29/month with 0% platform transaction fees. Its drag-and-drop editor is the easiest on this list, and it handles physical goods, digital products, subscriptions, and bookings out of the box. Squarespace starts lower (Core at $17/month annual) and ships the best-looking templates in the industry, all free. Just avoid its Business plan for selling: it takes a 3% cut of every order.
The ceiling is real. Both suit stores under roughly 500 products, and Squarespace offers only 40 to 50 integrations against Shopify’s 8,000+ apps.
Pick one if: you’re a creator, service seller, or boutique brand where design sells the product.
Adobe Commerce (Magento): Enterprise Power at Enterprise Cost
Adobe Commerce handles millions of SKUs, complex B2B workflows, and multi-store international setups better than anything else here. It also starts around $22,000 per year for the cloud version before development, and every serious build needs dedicated developers.
The free open-source Magento edition still exists, but the same math applies: you pay in engineering hours instead of license fees. For a first store, this is the wrong tool. For a manufacturer with 50,000 SKUs and custom pricing logic, it’s often the right one.
What Your Store Actually Costs: A Worked Example
Say your business plan projects $10,000/month in sales at an $80 average order (125 orders). Here’s a realistic monthly bill on the two most common picks:
Shopify Basic (annual): $29 plan + $327.50 processing (2.9% + $0.30 x 125) + roughly $50 in apps = about $407/month.
WooCommerce: $40 managed hosting + $290 Stripe processing (2.9% + $0.30) + $60 in premium extensions = about $390/month, before any developer time.
At this volume the platforms cost nearly the same. The difference is where your hours go: Shopify trades money for time, WooCommerce trades time for control. Run this math at your own projected volume before committing, because switching platforms later means migrating products, customers, orders, and SEO redirects. That’s weeks of work and real risk.
The 2026 Factor: Can AI Agents Find and Sell Your Products?
This is the gap most platform guides still miss. Shopping has a new front door. OpenAI’s Instant Checkout went live in September 2025, letting people buy inside ChatGPT (merchants pay a 4% fee per completed order). Google answered with its Universal Commerce Protocol in January 2026, backed by Walmart, Target, and 20+ retailers. McKinsey projects agentic commerce will redirect $3 to $5 trillion in global retail spend by 2030.
AI agents don’t browse pretty pages. They read structured data. Pages with schema markup get cited 3.1x more often in Google AI Overviews, and 71% of pages ChatGPT cites include structured data. Practical checklist for any platform you choose:
- Complete product feeds: titles, GTINs, attributes, live inventory, and pricing with no gaps
- Product and FAQ schema markup on every product page
- Protocol readiness: Shopify’s Agentic Storefronts covers ACP and UCP natively; WooCommerce needs plugins; BigCommerce connects through its APIs
- Fast, crawlable pages, since agents skip listings they can’t parse
Choose a platform that treats AI visibility as infrastructure, not an afterthought. In 2026, that tilts the field toward Shopify and BigCommerce for most merchants.
Your 90-Day Launch Plan
Days 1-15: Validate the idea. Define your catalog size, average order value, and acquisition channel (content, paid social, or marketplaces). That single decision narrows your platform shortlist to two.
Days 16-30: Run the cost math above at your projected volume for both finalists. Start free trials, load 10 real products into each, and test checkout on your phone.
Days 31-60: Commit and build. Set up payments, taxes, shipping rules, and legal pages. Add Product schema and connect Google Search Console. Write your first five product descriptions for humans and agents alike: specific attributes, honest specs, clear pricing.
Days 61-90: Soft launch. Fix friction, then push your catalog to Google Shopping and one AI shopping surface. Measure conversion against the 3.65% eCommerce average reported by Adobe and iterate from there.
FAQs
Which eCommerce platform is best for beginners in 2026?
Shopify Basic at $29/month (annual) is the safest start: fully hosted, quick setup, and AI shopping channels included. Wix is easier still for stores under 500 products.
What is the cheapest way to start an online store?
Shopify Starter at $5/month sells through social and checkout links without a full site. For a real storefront on a budget, Squarespace Core at $17/month or WooCommerce on $25/month hosting are the lowest entry points.
Is WooCommerce really free?
The plugin is free. Hosting, themes, extensions, and maintenance are not. A realistic small-store budget is $30 to $100 per month, more with developer help.
Shopify or BigCommerce: which has lower fees?
BigCommerce charges no platform transaction fees on any plan with any gateway. Shopify matches that only if you use Shopify Payments; third-party gateways cost an extra 0.6% to 2%.
Which platform is best for SEO?
WooCommerce offers the most control (full URL freedom, WordPress publishing). Shopify and BigCommerce cover solid fundamentals; Shopify locks URLs into /products/ paths.
Can customers buy my products through ChatGPT?
Yes, if your platform supports the Agentic Commerce Protocol. Shopify merchants connect through Agentic Storefronts; OpenAI charges 4% per completed in-chat order.
When should I upgrade to Shopify Plus?
Around $1M to $2M in annual sales, when checkout customization, B2B features, and lower processing rates justify the $2,300/month commitment.
How long does it take to launch an online store?
On Shopify, Wix, or Squarespace, a focused founder can launch in 2 to 4 weeks. WooCommerce typically takes 4 to 8 weeks; Adobe Commerce projects run 3 to 9 months.
