Shopify Plus will quote you $2,300 a month before you've negotiated a single line item. For a brand doing $3M–$15M ARR, that's $27,600 a year just for the platform — before apps, before the 0.15–0.25% transaction fee on third-party gateways, before the Shopify-tax on every checkout customization that requires a developer.
I ran two stores past $1M ARR on Shopify's standard plans. The moment the Plus sales rep called, I did the math. The pitch was compelling; the invoice was not. If you're in that mid-market band — roughly $2M to $20M GMV — and you're being pushed toward Plus, you owe it to yourself to look at the Shopify Plus alternatives mid-market operators are actually using in 2024.
This post covers four real contenders: BigCommerce Enterprise, Medusa.js (self-hosted), Commercetools (composable), and WooCommerce with a managed host. I'll tell you who each one is actually for, what it costs in practice, and where it breaks down. No vendor cheerleading.
Why Mid-Market Brands Feel the Squeeze on Plus
Shopify Plus is priced for brands that need hand-holding and have the margin to pay for it. The platform is genuinely good — I'm not here to trash it. But the mid-market math is awkward.
At $5M GMV with a 0.2% transaction fee, you're handing Shopify $10,000 a year just for using Stripe instead of Shopify Payments. Add $2,300/mo base, a handful of apps at $50–$300/mo each, and a Shopify-specialized developer at $120–$180/hr for any checkout script work, and you're easily at $60,000–$80,000 in annual platform costs. That's a full-time hire.
The pain points I hear most often from operators in this range:
- B2B pricing rules that require Plus or a $300/mo app
- Checkout extensibility that's still limited unless you're on the new checkout extensibility framework (and migrating legacy scripts is a project)
- Multi-storefront setups that cost an extra $250/mo per expansion store
- Catalog complexity — more than 100 variants per product still hits a hard wall
If none of those apply to you, stay on Shopify Advanced at $399/mo and call it a day. But if two or more of those are real problems, keep reading.
BigCommerce Enterprise: The Closest Drop-In
BigCommerce Enterprise is the most direct swap. Same SaaS model, similar app ecosystem, no transaction fees on any payment gateway — that last point alone saves $10,000/yr at $5M GMV compared to Plus.
Pricing is negotiated, but expect $1,000–$1,500/mo for a mid-market contract, roughly 35–55% less than Plus. BigCommerce also doesn't charge per storefront for multi-channel setups the same way Shopify does.
Where BigCommerce wins for mid-market:
- Native B2B features (price lists, customer groups, quote management) included without an app
- No variant limit — 600 variants per product vs. Shopify's 100
- Open checkout — you can customize the checkout page without a proprietary scripting language
- Headless-ready via their Catalyst storefront (Next.js-based, open source as of 2023)
Where it falls short: the app ecosystem is thinner. Shopify has ~8,000 apps; BigCommerce has ~1,200. If your stack relies on a niche Shopify app, check compatibility before you migrate. Their theme ecosystem is also weaker — Cornerstone is fine, but it's not Shopify's Dawn.
My honest take: if you're a B2B or B2B2C brand doing $3M–$15M GMV and you're not deeply embedded in Shopify's app ecosystem, BigCommerce Enterprise is the first call I'd make.
Medusa.js: For Teams Who Can Handle Open Source
Medusa.js (v2.0 released October 2024) is an open-source, Node.js-based commerce engine. It's MIT licensed, self-hosted or deployable on Railway/Render/AWS, and free at the core. The company monetizes through Medusa Cloud (managed hosting), but you can run it yourself.
This is not a Shopify replacement you hand to a non-technical operator. You need a developer — ideally one comfortable with TypeScript and a headless frontend (Next.js or similar). The setup time for a production-ready store is 2–6 weeks depending on integrations.
Where Medusa wins:
- Zero platform fees — your only costs are hosting (~$50–$200/mo on Railway for mid-market traffic) and developer time
- Full customization — the data model is yours, the checkout is yours, the APIs are yours
- Modules architecture in v2 — swap out just the cart module, just the payment module, without rebuilding everything
- B2B, subscriptions, multi-region all supported in core or via official plugins
Real cost picture: hosting at $100/mo, a part-time developer at 10 hrs/mo for maintenance at $120/hr = $1,300/mo total. That's $15,600/yr versus $27,600+ for Plus — and you own the stack.
Where it breaks down: no built-in admin UI that a non-developer can run confidently on day one (it's improving fast, but it's not Shopify's admin). If your ops team is one person who isn't technical, Medusa will create support tickets, not close them.
If you want to go deeper on headless setups for stores in this revenue range, I wrote about building a headless storefront on a mid-market budget that pairs well with this section.
Commercetools: Composable Commerce Done Seriously
Commercetools is the platform that enterprise teams name-drop when they want to sound sophisticated. It's a genuine API-first, composable commerce platform — no frontend, no templating, pure headless. Every feature (cart, catalog, pricing, promotions) is a separate API.
Pricing: Commercetools starts around $3,000–$5,000/mo for mid-market contracts. That's more than Plus. So why is it on this list?
Because for brands with genuine complexity — multiple regions, multiple business models (D2C + wholesale + marketplace), or aggressive customization needs — the total cost of ownership can be lower than Plus once you factor in what you'd spend on apps and developers working around platform constraints.
A brand running D2C in 4 countries with 3 currencies and a wholesale portal on Shopify Plus would need: Plus ($2,300/mo) + Wholesale app ($300/mo) + multi-currency handling + custom checkout work. That's $35,000+/yr before developer hours. Commercetools consolidates that into one platform with native support for all of it.
Where Commercetools is the wrong choice: if you don't have a dedicated frontend team (or budget for one), you'll spend $40,000+ in agency fees before you launch. The platform is genuinely powerful, but it assumes you're bringing your own frontend, your own CMS, and your own search. MACH architecture is real work.
I'd only recommend Commercetools to mid-market brands that are already running a headless frontend, have a 2-person+ dev team, and are hitting hard walls on Shopify's data model. Otherwise, you're paying for complexity you don't need yet.
WooCommerce + Managed Hosting: The Underrated Option
Every SaaS-first person in e-commerce will tell you WooCommerce doesn't scale. They're wrong, with an asterisk.
WooCommerce on bad hosting doesn't scale. WooCommerce on Nexcess, Kinsta, or Pressable (all WooCommerce-specialized managed hosts, $50–$500/mo depending on traffic) handles mid-market volume without drama. Nexcess's Managed WooCommerce plans start at $19/mo for small stores and scale to ~$500/mo for high-traffic sites — that's the entire hosting bill.
The real cost of WooCommerce at mid-market:
- Hosting: $200–$500/mo (Nexcess or Kinsta at mid-market traffic)
- Developer: 5–15 hrs/mo for updates, maintenance, $80–$120/hr
- Plugins: $500–$2,000/yr for premium plugins (WooCommerce Subscriptions, WPML, etc.)
- Total: ~$15,000–$25,000/yr
That's half to two-thirds of Shopify Plus costs, and you own the data and the codebase.
Where WooCommerce earns its place: content-heavy brands where the CMS is WordPress and the commerce is secondary, B2B brands with complex quoting workflows (WooCommerce + WC Quote plugins are genuinely good), and operators who already have WordPress developers on retainer.
Where it breaks down: checkout conversion optimization is harder — you're A/B testing against a PHP template, not a React component. The security surface is larger than a SaaS platform. And plugin conflicts are a real operational tax. I've spent weekends debugging a WooCommerce update that broke a payment gateway. That's not fun at $5M GMV.

The Decision I'd Make in Your Shoes
Here's how I'd actually choose, based on the one variable that matters most: your team's technical capacity.
No in-house developer, ops-first team: BigCommerce Enterprise. Negotiate hard — I've seen contracts come in at $900/mo for brands under $8M GMV. The no-transaction-fee savings alone often cover the platform cost difference versus Shopify Advanced.
One solid full-stack developer on staff: Medusa.js v2. Spend 3 weeks setting it up properly, use Next.js Commerce as your frontend starting point, and you'll have a platform you can customize without paying a SaaS tax forever.
WordPress-native brand with existing WP developer: WooCommerce on Nexcess or Kinsta. Don't fight your existing stack. Optimize it.
Multi-region, multi-business-model complexity, dev team of 2+: Commercetools. It's expensive upfront and operationally demanding, but if you genuinely need it, the alternatives will cost you more in workarounds.
The Shopify Plus alternatives mid-market conversation isn't really about platforms — it's about where your money goes. Shopify Plus is a premium for convenience and ecosystem. If you're getting full value from that convenience, pay it. If you're paying it and still hiring developers to work around platform limits, that's the signal to move.
Tomorrow's action: Pull your last 12 months of Shopify costs — platform fee, apps, transaction fees, developer hours for Shopify-specific work. Put that number next to the BigCommerce Enterprise quote you're going to request this week. The gap will tell you everything.
