Who actually runs on what in 2026

Market share numbers get quoted loosely because every tracker uses a different denominator. Here's the honest breakdown, with sources.

• 01
  WooCommerce leads on store count: 4,341,142 live stores vs Shopify's 2,844,435 in StoreLeads' May 2026 dataset. Count every install and WooCommerce's footprint is even bigger — WordPress.org reports 7M+ active plugin installations.
• 02
  Shopify leads where the money is. Among the top 1 million ecommerce sites (BuiltWith), Shopify holds 28.8% vs WooCommerce's 18.2%. Higher-traffic, higher-revenue stores skew Shopify — the segment most platform decisions at your scale actually compete in.
• 03
  The GMV gap is roughly 9x. Shopify processed $292B in GMV in 2024 and was pacing past $350B in 2025. WooCommerce's ecosystem generates an estimated $30–35B annually. Store count and merchant value are different games.
• 04
  WooCommerce has plateaued. Live stores peaked at 4,748,170 in Q4 2024 and now sit about 8.6% below that peak. It's a mature, replacement-and-optimization market — not a dying one, but no longer hyper-growth. Track the platform race month to month in ECM Insights.
• 05
  Shopify Plus now counts roughly 76,600 stores, adding 300+ new merchants weekly. Gymshark, Red Bull, and LVMH brands run on it, which is why Shopify dominates the top-traffic tiers.
• 06
  The WordPress gravity well is real. WordPress powers about 43% of all websites, and W3Techs puts WooCommerce at 49% of known ecommerce systems in its sample. If your brand is content-heavy, this ecosystem is the pull.
• 07
  Migration flow runs one direction. In Cart2Cart's March 2026 tracking, WooCommerce→Shopify was the single largest migration path (56 of 241 tracked migrations), and Shopify captured 8,993 WooCommerce stores in one recent 90-day window per Swell's analysis.

The real cost math at three revenue tiers

"WooCommerce is free" and "Shopify is $39/month" are both marketing. Here's what each platform costs to operate in 2026 once you include processing, apps, hosting, and the developer hours nobody budgets for.

The 2026 price sheet

• →
  Shopify plans: Basic $39/mo ($29 annual), Grow $105/mo ($79 annual), Advanced $399/mo ($299 annual), Plus from $2,500/mo on a 1-year term ($2,300 on 3-year). Plus converts to a 0.25% variable fee above $1M in monthly GMV.
• →
  Shopify Payments rates: 2.9% + 30¢ (Basic), 2.7% (Grow), 2.5% (Advanced), 2.15% (Plus, negotiable). Use a third-party gateway and Shopify adds a 2% / 1% / 0.6% / 0.2% surcharge by plan — the hidden fee that quietly reprices the whole comparison.
• →
  Shopify app spend is the real line item: the average merchant runs $120–300/mo in apps; a growing store typically pays $400–1,200/mo across email, reviews, subscriptions, and analytics. Roughly 4.5% of revenue flowing to the Shopify ecosystem is typical for a $200–500K/mo store.
• →
  WooCommerce core is $0, the stack isn't: managed hosting runs $50–700/mo at scale (Kinsta, WP Engine, Cloudways), essential extensions $500–2,500/yr, and professional maintenance retainers $500–3,000/mo. US developer rates average around $120/hr freelance.
• →
  WooCommerce charges zero platform transaction fees. You pay only your gateway's rate (Stripe: 2.9% + 30¢). That neutrality matters most in markets where Shopify Payments isn't available — Indian merchants, for example, permanently eat a 0.6–2% surcharge on Shopify.

TCO at $1M / $5M / $20M annual revenue

• →
  At ~$1M/yr ($83K/mo): Shopify Grow with Shopify Payments lands around $105 + ~$2,250 processing + $300–600 apps ≈ $2,700–3,000/mo. A comparable WooCommerce build: $150–300 hosting + ~$2,450 Stripe processing + $200–400 plugins/maintenance ≈ $2,800–3,200/mo. Near-parity — the tiebreaker is who maintains it.
• →
  At ~$5M/yr ($417K/mo): Shopify Advanced: $399 + ~$10,400 processing (2.5%) + $600–1,200 apps ≈ $11,400–12,000/mo. WooCommerce with serious managed hosting and a maintenance retainer: $400–700 hosting + ~$12,100 processing + $1,000–2,500 dev/retainer ≈ $13,500–15,300/mo. Shopify's negotiated rates and bundled infrastructure start pulling ahead — IWD Agency's 2026 analysis reaches the same conclusion for sub-$500K/mo GMV stores.
• →
  At ~$20M/yr ($1.67M/mo): Shopify Plus: ~$2,500 base converting to variable fees + ~$35,900 processing (2.15%) + $1,500–3,000 apps. WooCommerce at this scale demands dedicated DevOps, Redis/CDN architecture, and enterprise hosting — plenty of $10M+ GMV brands run it, but per IWD, above $10M GMV Shopify Plus or Adobe Commerce typically delivers better TCO unless your workflows genuinely can't live inside Shopify.
• →
  The crossover pattern: WooCommerce is cheaper when you have in-house WordPress capacity and stable requirements. Shopify gets cheaper as revenue grows, because infrastructure, security, PCI compliance, and peak-traffic scaling are bundled. Run your own numbers in the ECM platform calculator before you trust anyone's blog math, including ours.

The conversion data that decides most migrations

Platform costs are visible on an invoice. Conversion deltas are invisible until you measure them — and at $5M+ in revenue, a single point of checkout completion is worth more than every hosting bill combined. Benchmark your own funnel against the ECM KPI Library before reading on.

• 01
  Shopify's checkout converts 15% better on average than competing platforms, up to 36% in like-for-like samples, per an independent study by a Big Three consulting firm. It measures checkout completion specifically, not overall store conversion — but checkout is exactly where paid traffic dies.
• 02
  Shop Pay lifts conversion up to 50% vs guest checkout and outperforms other accelerated checkouts by at least 10%. Shopify's internal 2025 data shows Shop Pay converting 1.72x standard checkout overall and 1.91x on mobile.
• 03
  150M+ registered Shop Pay users mean a meaningful share of your first-time visitors arrive with payment credentials already saved. There is no WooCommerce equivalent to this identity network — express wallets like Apple Pay and PayPal help, but don't recognize shoppers across millions of stores.
• 04
  Baseline benchmarks for context: the average Shopify store converts at 1.4%; the top 20% clear 3.2% and the top 10% clear 4.7% (Littledata). Cart abandonment averages 70.19% across retail. Platform choice moves the needle, but CRO execution moves it further.
• 05
  WooCommerce's checkout is fully customizable — which cuts both ways. An actively optimized WooCommerce checkout with express wallets can be excellent. An unmaintained one is a liability. Shopify's one-page checkout (default, converting ~7.5% better than multi-page) means the floor is high even with zero optimization effort.
• 06
  Speed gap out of the box: Shopify stores average a 1.8-second page load with no tuning, while only 51% of WooCommerce stores hit sub-second speeds even after optimization work, per tech-insider.org's 2026 platform testing. Every 100ms of latency taxes conversion; on WooCommerce you pay engineers to buy that speed back.

Where the engineering hours actually go

The line item that never appears in platform comparisons is your team's time. It's also the one operators feel most.

The WooCommerce operational load

• →
  You own the full stack: PHP versioning, MySQL performance, plugin compatibility, security patching, and backups. Professional maintenance runs $500–3,000/mo, or it comes out of your own team's sprint capacity.
• →
  Plugin sprawl is the recurring failure mode. A typical mid-market WooCommerce store runs 20–40 plugins; every WordPress core update is a compatibility roll of the dice, and the 2023 WooCommerce Payments vulnerability showed what an unpatched stack costs.
• →
  Peak-traffic scaling is on you. Black Friday capacity means load testing, object caching (Redis/Memcached), CDN configuration, and database tuning — solvable, but it's real architecture work, not a checkbox. An honest tech stack audit before Q4 is non-negotiable on Woo.

The Shopify operational trade

• →
  Infrastructure, 99.99% uptime, PCI DSS Level 1 compliance, and traffic-spike handling are bundled into the plan fee. Your team's hours shift from keeping the store alive to growing it — the "focus leak" argument migration agencies keep winning with.
• →
  The trade is control: /products/ and /collections/ URL structures are locked, checkout customization below Plus is limited, and product architecture caps at 3 options and 100 variants (a genuine blocker for configurable catalogs).
• →
  Since April 2026, foundational B2B (company profiles, price lists, net terms) ships on every Shopify plan — wholesale is no longer a Plus-only argument. Advanced B2B (unlimited catalogs, partial payments, deposits) still is.
• →
  Shopify Magic bundles AI product descriptions, segmentation, and content generation at no extra cost; matching that on WooCommerce means $30–150/mo in third-party AI plugins plus configuration time.

SEO: WooCommerce for content, Shopify for product visibility

This is the one category where WooCommerce still holds a structural edge — but the gap narrowed meaningfully in 2025–2026.

• 01
  WooCommerce inherits WordPress's full CMS. Yoast/Rank Math give granular control of meta, schema, canonicals, and URL structure with zero platform-imposed paths. For brands where organic content drives a meaningful revenue share, this is still the stronger foundation.
• 02
  Shopify closed most of the technical gap: its 2026 updates added native JSON-LD for Product, Review, FAQ, and Breadcrumb schema without apps. What it hasn't fixed: hard-coded /products/ and /collections/ URL paths, which complicate large-catalog migrations from established URL structures.
• 03
  The AI-search wrinkle favors Shopify's defaults. Agencies like Shero report Shopify product pages increasingly surfacing in Google AI Overviews and Perplexity carousels with no merchant-side optimization, a function of default product schema. WooCommerce can match it, but most stores haven't done the configuration.
• 04
  Migration doesn't have to torch your rankings. Shero's Gen Y Hitch case (WooCommerce→Shopify, Dec 2025) saw organic sessions recover and grow 10.7% within three months of launch. The typical pattern in documented cases: a ~15% traffic dip in month one, full recovery by month three — if every redirect is mapped. If organic is your primary channel, get a specialist SEO partner on the redirect map before launch, not after.

When each platform actually wins

Strip the tribalism and the profiles are clean. Score yourself honestly against these.

WooCommerce wins when

• →
  You have a strong in-house WordPress/PHP team or a trusted dev partner, and workflows that don't fit Shopify's plans without justifying Plus.
• →
  Content is your growth engine — editorial SEO, resource hubs, communities — and commerce sits inside a WordPress property that already ranks. Compare notes on the ECM WooCommerce review.
• →
  You operate in a market without Shopify Payments and refuse to hand over a permanent 0.6–2% surcharge, or you need custom checkout logic, unlimited variants, or ownership of the full codebase.

Shopify wins when

• →
  Ecommerce is the business, not a feature of it. Paid traffic efficiency, checkout conversion, and peak reliability outweigh URL control and codebase ownership. Full breakdown in the ECM Shopify review.
• →
  Your team is lean and operational hours are your scarcest resource — the bundled infrastructure trade is exactly the point at $5M–$50M with a 2–6 person ecomm team.
• →
  You're scaling past $500K/mo GMV, where negotiated Plus rates, Shop Pay's conversion lift, and bundled compliance flip the TCO math — and where an omnichannel or B2B motion benefits from features now included on every plan.

If you're switching: the numbers to budget

Replatforming is worth it when the cost of staying exceeds the cost of moving. The problem is that the cost of staying hides in developer hours and lost peak revenue, so most merchants move later than they should.

• 01
  Budget $10,000–$100,000+ for a proper mid-market migration covering development, data mapping, redirects, and SEO recovery work. A documented $5M-revenue, 2,000-SKU WooCommerce→Shopify Plus move cost $18K plus ~$2K/mo in platform fees — and cut hosting costs 40%.
• 02
  Timeline: 4–12 weeks for a proper migration, not the "one week" stories. Products, customers, and orders come over (orders need LitExtension or Matrixify); customer passwords don't — plan the reset-comms email. Reviews need a third-party app and CSV export.
• 03
  Watch the variant ceiling. Shopify caps products at 3 options and 100 variants. WooCommerce variable products with 4+ attributes must be restructured before migration or they lose options silently.
• 04
  Migration savings claims run 20–30% in operational overhead for merchants leaving self-hosted stacks — credible if you're currently paying managed hosting plus a retainer, inflated if a founder was doing maintenance for free. Model your own three-year numbers before signing anything, and pressure-test the ROI against your core KPIs, not the agency's deck.
• 05
  The single biggest failure mode is launching before redirects are validated. APPWRK's post-mortem across 110 migrations: unvalidated 301s produce hundreds of indexed 404s and a 2–6 month recovery. Verify every redirect, then launch.
