The 5-Year TCO of Ecommerce Platforms: Shopify Plus vs WooCommerce vs Next.js Headless (2026 Numbers)

The most expensive mistake in ecommerce platform selection is comparing build costs. Build cost is one line item over a few months. Total cost of ownership (TCO) is everything you’ll pay over five years — platform fees, hosting, plugins, transaction fees, developer maintenance, the migration tax when you outgrow your choice. The platforms that look cheap upfront often have the highest TCO; the ones that look expensive upfront sometimes don’t.

This piece walks the actual 5-year TCO of Shopify Plus, WooCommerce, and Next.js headless across four GMV tiers, with current 2026 pricing, and the honest cases where each platform wins.

Why build cost is the wrong number to optimize

Founders and finance teams comparing platforms almost always anchor on the implementation quote. That number is real but small relative to the operational costs that follow. A representative 5-year split for a mid-market ecommerce business looks like this:

Initial build: 5–15% of total spend.
Platform and hosting fees: 25–40%.
Apps, plugins, and integrations: 10–20%.
Transaction fees: 15–25% (highly variable).
Developer maintenance and feature work: 20–35%.

Optimizing the 5–15% slice and ignoring the 85% is the path most teams take, and it’s why platform decisions made for cost reasons in year one often look catastrophic in year three.

What 2026 pricing actually looks like

Before walking the TCO model, the current state of platform pricing matters — some of these numbers shifted significantly in 2024–2025 and have settled into a new equilibrium.

Shopify Plus (verified 2026 pricing)

Base: $2,300/month on a 3-year contract, or $2,500/month on a 1-year term.
Variable fee: Above approximately $800,000 in monthly GMV, the platform fee shifts to 0.25%–0.40% of GMV (typically 0.25% on 3-year contracts, higher on 1-year).
Cap: Generally $40,000/month.
Transaction fees: 0% with Shopify Payments; 0.15% on Plus tier when using third-party gateways (lower than non-Plus tiers).
Includes: 9 expansion stores at no extra platform fee.

Note: this is the post-2024 pricing model. Older articles citing $2,000 flat fees or 0.15% over $2M are using the previous pricing structure.

WooCommerce (open source)

Software cost: $0. WooCommerce itself is free.
Hosting: $30–$80/month for a small store on managed WordPress hosting (Pressable, Cloudways); $200–$600/month for serious managed (Kinsta, WP Engine); $1,000+/month for enterprise tiers with autoscaling.
Essential plugins: $200–$1,500/year for the canonical stack (subscriptions, advanced reporting, search, performance, security).
Transaction fees: Whatever your payment processor charges directly. Stripe is 2.9% + $0.30 in the US.
Developer maintenance: The variable that determines TCO. From a few hours/month for a stable site to a full-time developer for a complex one.

Next.js headless storefront

Hosting: Vercel Pro starts at $20/user/month plus usage; high-traffic stores routinely run $500–$3,000/month on hosting alone. Cloudflare/Netlify alternatives are cheaper.
Backend services: A headless setup needs a commerce engine — typically WooCommerce, Shopify, BigCommerce, or Saleor — plus a CMS (Sanity, Contentful, Payload), plus search (Algolia, Meilisearch), each with its own pricing.
Initial build: $30,000–$150,000+ depending on scope and feature parity with what’s being replaced.
Maintenance: Material. A custom Next.js storefront needs ongoing engineering capacity that doesn’t go away after launch.

The 5-year TCO walk, by GMV tier

The platform that wins on TCO depends almost entirely on what scale you’re operating at. The crossover points matter.

Tier 1: Startup / pre-PMF ($0–$50K annual GMV)

At this scale, every dollar matters and operational simplicity wins. Shopify Basic ($39/month) gets you live in days; the transaction fees are a small absolute number; the platform handles everything operational.

5-year estimated TCO:

Shopify Basic: $5,000–$15,000 (subscription + apps + a small build)
WooCommerce: $4,000–$12,000 (hosting + plugins + small build) — close, but operational burden is real
Next.js headless: $40,000+ — dramatic over-build for this scale

Verdict: Shopify or a very simple WooCommerce setup. Don’t custom-build at this stage; you don’t yet know what you’re building for.

Tier 2: Growth phase ($500K annual GMV, ~$42K/month)

Operational burden becomes meaningful, but you’re still well below Shopify Plus territory and the variable fee threshold.

5-year estimated TCO:

Shopify Advanced ($299/month + apps + transaction fees): $40,000–$80,000
WooCommerce on managed hosting + maintenance retainer: $30,000–$70,000
Next.js headless on Shopify or WooCommerce backend: $80,000–$180,000

Verdict: Shopify Advanced or WooCommerce. The TCO gap between them is small and usually decided by team capability — do you have someone who can manage WooCommerce hosting and updates, or would you rather pay Shopify to do it?

Tier 3: Mid-market ($2M annual GMV, ~$167K/month)

The economics start diverging. Shopify Plus becomes a real consideration for the customization access; WooCommerce starts paying back its open-source advantages.

5-year estimated TCO:

Shopify Advanced (still, with negotiated rates): $80,000–$140,000
Shopify Plus ($2,300–$2,500/month base, no variable yet): $200,000–$320,000 (incl. apps, transaction fees, and dev work)
WooCommerce with serious managed hosting + dedicated developer time: $120,000–$220,000
Next.js headless on WooCommerce or Shopify backend: $250,000–$450,000

Verdict: For most stores at this tier, the choice is Shopify Advanced (if you can get B2B and customization needs handled by apps) versus a well-run WooCommerce setup. The Plus upgrade is usually only worth it if you specifically need checkout customization, advanced flow logic, or expansion stores.

Tier 4: Enterprise ($10M+ annual GMV, ~$833K+/month)

Now Shopify Plus’s variable fee kicks in. The math gets more complex.

5-year estimated TCO at $10M annual GMV:

Shopify Plus (base + variable + apps + transaction fees + custom dev): $400,000–$700,000
WooCommerce with enterprise hosting + multi-developer team: $350,000–$650,000
Next.js headless on WooCommerce or Shopify backend: $550,000–$1,100,000

Verdict: Stops being a TCO question and becomes an operational question. Shopify Plus is the lowest-friction path; WooCommerce is genuinely cheaper on cash but requires real engineering investment; headless is the right call when conversion lift on the frontend justifies the engineering bill (and you can mathematically defend that lift).

The transaction fee math that matters

Transaction fees are where ecommerce platform TCO compounds quietly. The math:

Shopify Plus + Shopify Payments: No additional platform transaction fee on top of card processing. Effective rate ~2.15% + $0.30.
Shopify Plus + third-party gateway: 0.15% additional platform fee on top of the gateway’s rate. On $10M annual GMV, that’s $15,000/year just for the privilege of using Stripe instead of Shopify Payments.
WooCommerce + Stripe: No platform transaction fee. Just Stripe’s ~2.9% + $0.30 (US).
Next.js + any gateway: No platform fee.

For most US-based stores, Shopify Payments is competitive enough that the "Shopify locks you into their gateway" criticism is more theoretical than practical. The math gets worse in markets where Shopify Payments isn’t available, where the platform’s fee on third-party gateways becomes a real cost.

The migration tax

The TCO calculation that almost no one models is the cost of switching platforms. From the migrations we’ve shipped, realistic budgets:

Small WooCommerce → Shopify (or vice versa): $15,000–$50,000 plus 2–3 months.
Mid-market WooCommerce → Shopify Plus: $40,000–$120,000 plus 4–6 months. Data migration and URL preservation are the variable line items.
Shopify or WooCommerce → Next.js headless: $50,000–$200,000+ plus 4–8 months. The frontend rebuild is the bulk of the work.
Headless → anything: Materially harder. Custom code locks you in more than you expect.

The implication: choose for where you’ll be in 3 years, not where you are today, but don’t over-build for hypotheticals. The right answer at $500K GMV becomes wrong at $5M; the right answer at $5M was almost certainly wrong at $500K.

Where each platform genuinely wins

Stripping the marketing away, the cases where each platform is the right answer:

Shopify (and Shopify Plus) wins when: the business is operationally resource-constrained; the catalog is straightforward retail; the team values shipping speed over architectural control; the GMV is high enough that Plus’s variable fee isn’t punishing relative to dev costs you’d otherwise pay.

WooCommerce wins when: the business has access to engineering capacity (in-house or trusted agency); the data ownership matters strategically; the catalog has unusual requirements (complex pricing, B2B, subscriptions, custom workflows) that map to mature plugins; you want to avoid revenue-share platform fees.

Next.js headless wins when: conversion-rate lift on the frontend is large enough to mathematically justify the engineering bill; the brand needs UI experiences that platform themes can’t deliver; the team has senior engineering capacity that can be dedicated to the storefront indefinitely; integration with non-commerce systems (custom CRM, ERP, internal tools) is a feature, not a bolt-on.

How we approach this in client work

For most brands the right answer is one of: a well-run Shopify or Shopify Plus setup; a well-run WooCommerce setup with real attention to caching, security, and HPOS; or a hybrid where WooCommerce powers the backend and a Next.js or Astro frontend handles the experience layer. The all-custom Next.js headless route is rarely the right call until the brand is large enough that conversion economics make the math obvious.

FAQ

What’s the single biggest TCO mistake teams make?

Comparing build costs and ignoring everything else. Build cost is 5–15% of 5-year spend on most ecommerce platforms. Optimizing it while ignoring platform fees, transaction fees, and developer maintenance is the path most teams take, and it’s why year-three regret is so common.

Is Shopify Plus’s variable fee worse than WooCommerce’s developer costs?

Not usually, in our experience. At $10M GMV, Shopify Plus’s variable fee runs $25,000–$40,000/year. A senior WooCommerce developer’s loaded cost is $120,000–$200,000+. The Plus fee is a tax on revenue; the developer is a fixed cost. Which one wins depends on whether you’d hire that developer regardless (e.g., for custom features WooCommerce uniquely enables).

How much does it actually cost to migrate platforms?

For mid-market stores: $40,000–$120,000 and 4–6 months for a WooCommerce ↔ Shopify Plus migration; $50,000–$200,000+ and 4–8 months for a headless rebuild. Data migration, URL preservation (for SEO), and parallel operation during cutover are the largest variable line items.

Does headless make sense for stores under $5M GMV?

Rarely. The engineering bill for a custom Next.js storefront is fixed regardless of revenue, and below $5M GMV, even a meaningful conversion lift doesn’t reliably pay for the engineering investment over five years. The exceptions are stores with very specific UI requirements (configurators, complex personalization) that platform themes genuinely can’t handle.

What’s the most overlooked cost on each platform?

For Shopify: app subscriptions. A typical Plus store easily runs $500–$2,000/month in app fees, and apps stack invisibly. For WooCommerce: developer time. Updates, security patches, and plugin compatibility audits add up to real hours. For headless: the "everything is custom" tax — every feature that would be a plugin install on WooCommerce is a build on Next.js.
