Shopify Plus vs BigCommerce Enterprise: the real 2026 cost and fit breakdown

The short version

BigCommerce Enterprise charges no platform transaction fee on any payment gateway, and its flat negotiated plan fee does not rise as a percentage of your sales. Shopify Plus has the deeper app and theme ecosystem and the most customisable checkout, but its platform fee is revenue-banded (a flat minimum or a small percentage of revenue, whichever is greater) and using any gateway other than Shopify Payments adds a per-sale surcharge. So the cost answer usually splits like this: high revenue paired with a third-party processor leans BigCommerce; a design-led brand committed to Shopify Payments and a rich app stack often still does best on Shopify Plus. The calculator above finds the revenue at which that flips for your inputs.

1. Transaction-fee models: 0% platform fee vs Shopify Payments lock-in

This is the single biggest structural difference, and it is the one most likely to decide the bill at scale.

BigCommerce charges zero platform transaction fees on every plan, including Enterprise, and lets you bring any of its supported gateways with no penalty. The only per-sale cost you pay is your own processor's rate, which is the same number you would pay anywhere.

Shopify Plus waives its per-sale platform surcharge only if you use Shopify Payments. Keep a third-party gateway (because you have a better-negotiated processor rate, a regional acquirer, or a B2B payment flow Shopify Payments does not cover) and Plus adds a small per-sale surcharge on top, reported around 0.2% on the Plus tier. That is the “Shopify Payments lock-in”: it is not that you cannot use another gateway, it is that doing so costs you a percentage of every order, forever.

Why it matters: a surcharge is a slope, not a fixed cost. At $100k/mo a 0.2% surcharge is $200; at $2M/mo it is $4,000 every month, money BigCommerce simply does not charge. If you are locked to Shopify Payments and happy with its rate, this difference vanishes. If you cannot move off a third-party gateway, it is the strongest single argument for BigCommerce.

Verdict by profile. High-SKU catalog: usually leans BigCommerce, because catalog stores more often run a third-party gateway and the surcharge compounds. High-design DTC: a wash if you stay on Shopify Payments, which most DTC brands do. B2B: leans BigCommerce, because B2B payment flows (net terms, offline payment, purchase orders) frequently need a gateway other than Shopify Payments.

2. Revenue-banded pricing thresholds

Neither platform publishes a fixed enterprise price; both are negotiated. But the shape of the price differs, and that shape is what you are really choosing.

Shopify Plus is widely reported to bill the greater of a flat monthly minimum (around $2,300/mo on an annual commitment) or a small percentage of monthly revenue (around 0.25%), capped at a ceiling (around $40,000/mo). The practical effect: below roughly $920k/mo in revenue you pay the flat base; above it, your platform fee scales with sales until it hits the cap. Your plan fee is, in part, a function of how well you sell.

BigCommerce Enterprise is a flat negotiated fee. BigCommerce does move you between pricing bands based on your trailing online sales volume, so growth can trigger a higher tier at renewal, but within a term the platform fee does not climb as a live percentage of each month's revenue. You trade Shopify's smooth revenue curve for a flat fee that steps up at negotiated thresholds.

The calculator above models both: it shows the revenue band you are in on Shopify Plus, and where the flat BigCommerce fee overtakes or undercuts it. Put your real growth projection in, not just today's number, because the winner can flip inside an 18-month horizon.

Verdict by profile. High-SKU catalog: at high GMV the Shopify revenue share can outweigh the flat BigCommerce fee, so model both at projected scale. High-design DTC: under the ~$920k/mo band most growing brands sit below, Shopify's flat base keeps it competitive. B2B: high AOV pushes revenue up fast for the same order count, so B2B stores hit the Shopify revenue band sooner than they expect.

3. Headless, B2B and multi-storefront support

This is where fit, not cost, should drive the decision.

Headless. Both support a headless build via storefront APIs (Shopify via the Storefront API and Hydrogen; BigCommerce as an “open SaaS” platform designed to be decoupled). BigCommerce has historically pitched harder to headless teams and is generous with API limits; Shopify's Hydrogen plus Oxygen hosting gives a first-party React stack. If you are going headless, weigh your team's framework preference and the API rate limits in writing, not the marketing.

B2B. Shopify B2B is native to Plus and shares one admin and catalog with your DTC store, which is excellent if your wholesale needs are relatively standard (company accounts, price lists, basic terms). BigCommerce B2B Edition is the more mature option for complex requirements: deep price lists, quoting, buyer hierarchies, and granular permissions. If B2B is your main business and the rules are intricate, BigCommerce usually needs fewer workarounds.

Multi-storefront. Both let you run multiple storefronts, locales and currencies. BigCommerce Enterprise includes multi-storefront in the platform; Shopify achieves it through Plus expansion stores and Markets. Count the stores and locales you actually need and confirm how shared catalog and inventory behave across them, because that detail decides operational pain more than the headline feature.

Verdict by profile. High-SKU catalog: leans BigCommerce for native catalog, faceted search and multi-storefront. High-design DTC: leans Shopify Plus for checkout customisation and ecosystem. B2B: a genuine split, simple B2B leans Shopify, complex B2B leans BigCommerce B2B Edition.

4. App-ecosystem cost

Headline plan fees hide a real number: the monthly cost of the apps you bolt on to reach the features you need. The two platforms invert here.

Shopify has by far the larger app store, which is a genuine strength: there is almost always an app for what you want. The flip side is that more of Shopify's capability is delivered through paid apps, so a feature-rich Plus store often carries a heavier monthly app bill, and app costs themselves can be revenue-banded.

BigCommerce builds more into the core platform (faceted search, multi-currency, B2B basics, customer groups), so stores frequently reach the same feature set with fewer paid add-ons. Its marketplace is smaller, which occasionally means a niche integration is missing and you build it.

The honest way to compare is not “who has more apps” but “what does the app stack I actually need cost on each.” The calculator has separate Shopify and BigCommerce app-cost inputs for exactly this reason: put your real quoted stack in both columns.

Verdict by profile. High-SKU catalog: BigCommerce often needs fewer apps for catalog and search. High-design DTC: Shopify's ecosystem is worth the heavier app bill if those apps are what make the brand. B2B: depends entirely on whether B2B features come from core or from add-ons, price both stacks.

5. Migration effort

Migration is a one-off cost, but it is large enough to swing a close decision, and it is where stores most often underestimate the bill.

The work is broadly the same shape on either platform: export products, variants, customers and order history; rebuild or port the theme; reconnect ERP, PIM, OMS and tax integrations; and, critically, build a complete 301 redirect map so you do not lose the SEO equity in your existing URLs. The cost driver is not the destination platform so much as your catalog complexity, the number of integrations, and how custom your current storefront is.

Two platform-specific notes. If you are already on a lower Shopify tier, moving up to Plus is a far smaller lift than a cross-platform migration, because your data, theme and apps largely carry over, that incumbency advantage is real and worth weighing. Moving from any other platform to BigCommerce or to Shopify Plus is a true replatform: budget professional-services time, a staging rebuild, and a redirect plan, and do not let either vendor quote you a timeline without a written migration plan attached.

Verdict by profile. High-SKU catalog: migration is heaviest here (catalog and feed mapping dominate), so the incumbency advantage of staying within one ecosystem matters most. High-design DTC: theme rebuild is the long pole; budget design time on either platform. B2B: integration and price-list migration is the risk, scope it explicitly in the RFP.

Get comparable quotes: the replatforming RFP template

Two enterprise quotes are only comparable if you asked both vendors the same questions. Below is the template we would send: fee model and cap, payment-gateway penalty, catalog and B2B limits, headless API limits, a written migration plan, and exit terms. Unlock it, send it to both, and put the answers side by side.

How the calculator builds the comparison

Each platform's all-in monthly cost is its platform fee, plus payment processing (held equal on both, because your processor sets that rate, not the platform), plus any per-sale platform surcharge, plus your paid apps. The only lines that differ are the platform fee and the surcharge. Shopify Plus's platform fee is the greater of the flat base and the revenue percentage, capped at the ceiling; its surcharge applies only when you opt out of Shopify Payments. BigCommerce's platform fee is flat and its surcharge is always zero.

Because one curve is flat and the other bends with revenue, they can cross. The calculator scans your revenue range to find that crossover and tells you which platform is cheaper above and below it. Every pricing assumption is an editable input pre-filled with a widely-reported baseline, so nothing is a figure you cannot replace with your own quote. Enterprise pricing on both platforms is negotiated, so treat the output as a budgeting model, not a quote.
