Shopify Plus vs BigCommerce Enterprise: The 2026 Comparison

Shopify Plus vs BigCommerce Enterprise: The Core Difference

Both platforms sell to the same buyer: a merchant who has outgrown entry-level SaaS ecommerce and needs dedicated support, higher performance limits, and enterprise-grade B2B tooling. The split between them is architectural, not just a feature checklist.

Shopify Plus is an opinionated, hosted platform. Shopify controls the checkout, the core commerce logic, and most of the infrastructure. You extend it through apps, Shopify Functions, and checkout UI extensions rather than rewriting core flows. In exchange you get the largest app ecosystem in ecommerce and a fast, predictable path to launch.

BigCommerce Enterprise (now branded Performance) markets itself as an 'open SaaS' platform: still fully hosted and managed, but with fewer restrictions on checkout logic, catalog structure, and API access. It has historically been the stronger fit for manufacturers, distributors, and multi-brand businesses that need complex B2B pricing and multiple storefronts from one backend, without stitching together as many third-party apps.

Neither is objectively better. The right pick depends on your catalog complexity, your B2B requirements, your payment stack, and how much of your commerce logic you want to own versus rent.

Pricing in 2026: What You Actually Pay

This is the section where a 2025 comparison article will mislead you. BigCommerce overhauled its entire plan structure on June 1, 2026, and the change matters more than the headline sticker price on either platform.

Shopify Plus pricing

Shopify publishes Plus pricing directly. As of 2026, the base platform fee is $2,300/month on a 3-year term or $2,500/month on a 1-year term. Once a store's monthly sales pass roughly $800,000, pricing switches to a variable platform fee, capped at $40,000/month.

Transaction fees follow a simple rule: pay with Shopify Payments and Shopify charges no additional platform transaction fee, just standard card processing (roughly 2.15% + $0.30 for US domestic Visa/Mastercard). Route payments through a third-party gateway instead, and Shopify adds a surcharge of roughly 0.15% to 0.20% per transaction on top of whatever your gateway already charges. At meaningful volume, that surcharge is a real line item, not a rounding error.

BigCommerce Enterprise pricing after the June 2026 restructure

BigCommerce renamed every plan and introduced a new fee structure effective June 1, 2026. Standard became Core, Plus became Growth, Pro became Scale, and Enterprise became Performance. The headline change: a new Open Payment Provider Fee applies to self-serve plans that route orders through a payment processor not on BigCommerce's approved 'Embedded' list (which includes Stripe, PayPal, Adyen, and Klarna, among others).

The detail that actually matters for anyone specifically evaluating BigCommerce Enterprise: the Open Payment Provider Fee does not apply to Performance customers on contracted terms. It was built to catch self-serve merchants who never renegotiated their payment stack, not enterprise accounts. If your team is evaluating BigCommerce at the Performance tier through a sales rep, price the platform on the custom quote and the (now public) $1,499/month floor, not on the fee that's generating headlines for smaller merchants.

Neither platform publishes a single 'real' number for an enterprise deal. Model your own total cost of ownership against your actual GMV, payment gateway mix, and app stack before comparing a Shopify Plus quote to a BigCommerce Performance quote line by line.

Shopify Plus vs BigCommerce Enterprise for B2B

This is the fan-out query worth answering on its own, because B2B is where the two platforms diverge most in practice.

BigCommerce has invested in native B2B for years through its B2B Edition, which ships with customer groups and group-specific pricing, price lists with per-customer overrides, minimum order quantities, custom payment terms (net 30/60), quote management, sales rep assignment, catalog visibility by customer group, and purchase-order checkout. Much of this is available on lower plan tiers too, not gated entirely behind Performance.

Shopify rebuilt its B2B offering between 2022 and 2024 with B2B on Shopify, which now covers company profiles with multiple locations and contacts, net payment terms, per-company price lists, quantity pricing, and sales-rep-assisted draft orders. It closed most of the functional gap with BigCommerce, and its real advantage is unifying B2C and B2B on one storefront and one back office rather than running them as separate systems.

In practice: if you run a hybrid direct-to-consumer and wholesale brand and want one admin, one catalog, and one checkout, Shopify Plus is the more natural fit. If your business is B2B-first with complex tiered pricing, purchase-order workflows, and sales-rep-driven ordering as the primary channel, BigCommerce's more mature native tooling usually means fewer apps stitched on top.

Checkout Customization and Headless Architecture

Checkout used to be the clearest dividing line between the two platforms. Shopify locked checkout down tightly for years; BigCommerce let merchants touch more of it. That gap has narrowed.

Shopify replaced the old checkout.liquid customization model with checkout extensibility: Shopify Functions for backend logic (custom discounts, shipping rules, payment customizations) and Checkout UI Extensions for frontend additions, all without forking Shopify's core checkout code. That keeps checkout upgrade-safe, but you're still building within Shopify's extension points, not rewriting the flow from scratch.

BigCommerce continues to expose deeper native control over checkout, catalog structure, and storefront logic through its Stencil theme engine and open REST/GraphQL APIs, which is the practical meaning behind its 'open SaaS' positioning.

For headless builds, both platforms now have a credible first-party framework: Shopify offers Hydrogen (React) on Oxygen hosting, and BigCommerce offers Catalyst, built on Next.js. Both expose GraphQL storefront APIs. The choice between them at that point often comes down to your team's existing React/Next.js experience and which ecosystem's edge cases you'd rather debug, more than a hard capability gap.

What Merchants and Reviews Say

Strip out the vendor marketing and the recurring themes across enterprise buyer reviews are consistent year over year. Shopify Plus gets praised for admin usability, launch speed, and the sheer depth of its app and agency ecosystem, meaning almost any integration you need already has a mature, supported app. The recurring complaint is cost creep: app subscriptions stack up fast, and merchants who don't use Shopify Payments feel the third-party gateway surcharge.

BigCommerce Enterprise gets praised for native B2B depth, catalog flexibility, and not needing an app for every basic capability, which some merchants read as lower long-term app spend. The recurring complaint is a smaller app and theme marketplace, meaning less-common integrations more often require custom development rather than an off-the-shelf app, and a smaller freelance/agency talent pool to draw from compared to Shopify's ecosystem.

Neither platform has a structural reliability problem at enterprise scale; both run brands doing hundreds of millions in annual revenue. The reviews mostly diverge on ecosystem depth versus native flexibility, which tracks with the architectural difference described above.

Which Is Better: Shopify Plus or BigCommerce Enterprise?

There is no universal winner here, only a better fit for a given business model. Use this as a starting filter, then validate against an actual quote for your GMV and payment stack.

If you're weighing a migration either way, the harder work isn't the platform decision itself, it's mapping your existing catalog, customer groups, and integrations (ERP, marketplaces, payment gateway) onto the new platform without breaking anything mid-migration. That scoping work is what actually determines your real total cost, more than the base platform fee on either side. Our ecommerce platform migration and integration support covers exactly this: mapping the current stack, scoping the move, and handling the marketplace and payment integrations on the other side.

If you're still weighing which platform fits your specific catalog and B2B requirements, or you need more than just the migration itself, get a scoped quote across our services and we'll tell you plainly which parts of the move you actually need help with.
