How the pricing models actually differ

This is where most comparison guides go wrong. They line up two monthly numbers and call it a day. The models are structurally different, and that difference matters more than the sticker.

Shopify Plus is a flat fee that becomes a revenue share. You start at $2,300/month on a three-year term (or $2,500 on a one-year term), and that flat rate holds until your monthly GMV crosses roughly $800,000. Past that point you pay 0.25% of monthly GMV, whichever is higher, capped at $40,000/month once you hit about $16M in monthly sales. So a brand doing $2M a month pays around $5,000; a brand doing $5M a month pays about $12,500. The bill scales with you, cleanly and predictably.

BigCommerce Enterprise throws out the revenue share entirely. Pricing is quote-based, negotiated on GMV, catalog size, and storefront count, and typically lands between $1,000 and $3,000/month at entry (the published Performance-tier floor is $1,499/month). There is no percentage of your sales flowing back to the platform as you grow. For a fast-scaling brand, that structural difference can be worth more than the headline gap.

Then there is the fee that used to end every argument. BigCommerce charges no transaction fees on Enterprise, on any payment gateway. Shopify Plus is 0% only with Shopify Payments; a third-party gateway like Adyen or Stripe adds a 0.20% platform fee. On $50M in annual GMV routed through an external processor, that 0.20% is $100,000 a year. If you are contractually tied to a specific processor, price that line before anything else.

BigCommerce Enterprise vs Shopify Plus, head to head

Eleven dimensions that decide the contract, priced and specced as of July 2026. Enterprise pricing on both sides is quote-based, so the ranges reflect what merchants and partners actually report, not a public rate card.

Sources: Shopify Plus and BigCommerce pricing references, 2026 enterprise comparisons (Folio3, Fyresite, Codup, OroCommerce, Elogic), and Gartner/Forrester 2025 positioning. BigCommerce plan names reflect the June 1, 2026 rename (Enterprise→Performance). Both platforms negotiate enterprise pricing per contract; treat dollar figures as directional, not quotes.

B2B and multi-storefront: BigCommerce's home turf

If wholesale is a meaningful slice of your revenue, this section probably decides the whole thing. It is the clearest point of divergence between the two.

BigCommerce is B2B-first. Its B2B Edition, bundled with Enterprise, ships with customer groups, custom price lists, quote management, purchase orders, credit limits, and buyer portals out of the box. No apps, no glue code. Forrester named it a Strong Performer in B2B commerce, specifically citing the architecture. For a distributor or manufacturer with tiered pricing and organizational buyer hierarchies, that native depth is a real cost and complexity advantage.

Shopify Plus has closed a lot of ground, fast. B2B GMV on the platform grew 96% in 2025, and in April 2026 Shopify opened core B2B features to every paid plan, with the enterprise-grade pieces (unlimited catalogs, partial payments, deposits, payment terms) staying on Plus. It is genuinely strong now for running B2C and B2B from one store. The ceiling shows up in advanced workflows: complex approval chains, punchout catalogs, and deep company hierarchies still lean on apps like SparkLayer or custom Hydrogen builds.

Multi-storefront splits the same way. BigCommerce runs native multi-storefront from a single backend under one contract, so multi-brand and multi-region operators manage catalogs and pricing centrally. Shopify Plus uses expansion stores that behave as separate instances, which is why most Plus brands run an ERP or PIM as the source of truth and sync across stores. One model centralizes; the other federates. Match it to how your business is actually structured, and pull in a retention or lifecycle partner early if your B2B accounts drive repeat revenue.

Apps, checkout, and the API story

Here the advantage flips back toward Shopify on two of three fronts. This is where "control" and "convenience" stop being marketing words and start being engineering decisions.

App ecosystem: Shopify, decisively

Shopify's app store passed 12,000+ apps in 2026, the largest in commerce. For subscriptions, loyalty, reviews, personalization, and CRM connectivity, the odds that a mature, well-supported app already exists are high. That speed has a cost: a typical Plus store spends $500 to $1,000+ a month on apps, and a tech stack audit usually finds redundancy in there. BigCommerce's marketplace is smaller, which it offsets by shipping more features natively, so you buy fewer apps to reach the same place.

Checkout: freedom vs upgrade-safety

BigCommerce gives you open Checkout SDK access on every plan. You can rebuild the flow, add steps and fields, and write custom logic. More raw freedom, but it is a heavier engineering lift and you own that maintenance forever. Shopify routes checkout customization through Checkout Extensibility, where changes run in an approved sandbox. Less raw access, but your edits survive platform updates and do not put PCI compliance at risk. For most brands, upgrade-safe and maintainable beats unlimited but fragile.

API: BigCommerce's quiet win

BigCommerce Enterprise includes unlimited API calls. Shopify Plus is rate-limited, contract-dependent, around 40 requests per second on GraphQL. For standard operations that ceiling rarely bites. But if you are syncing inventory across warehouses in real time, repricing against competitors, or wiring in multiple ERPs, unlimited calls remove a whole class of workarounds (batching, caching, polling windows) that Shopify-heavy integrations have to engineer around.

Performance, support, and where each sits in the market

Both promise 99.99% uptime and both deliver it at scale. The soft factors are where the two brands genuinely differ, and they matter more than most spec sheets admit.

Shopify carries the market. It runs roughly 4.8 million stores worldwide, holds close to 30% of the US market, and has been a Gartner Magic Quadrant Leader for three straight years with the highest Ability to Execute in the field. Its global CDN gives storefronts a real speed edge, and that market position translates into easier hiring, a deeper agency bench, and customer trust signals at checkout. There are about 67,000 Plus domains live in 2026.

BigCommerce is the smaller, more specialized player. It powers around 40,000 live stores, a Gartner Challenger for six consecutive years, and its live store count was down roughly 8% year over year heading into 2026. That contraction is worth weighing honestly. It reflects a platform that has narrowed toward mid-market and enterprise merchants with real B2B and multi-store needs, but a smaller ecosystem also means a shallower talent pool and fewer off-the-shelf integrations.

One more thing changed the story this year. "No transaction fees, ever" was BigCommerce's sharpest line against Shopify. The June 2026 Open Payment Provider Fee (which does not touch Enterprise) blunted it on the self-serve tiers and made the platform read as slightly less differentiated than it did a month earlier. At the enterprise level the zero-fee advantage still stands, but the marketing halo around it is dimmer. If neither fits, the enterprise B2B crown still belongs to Adobe Commerce, and control-first teams keep an eye on open-source options.

How to actually decide

Skip the feature-count scoreboards. Four questions settle it, and they are about your business, not the platforms.

• 01
  How much of your revenue is B2B or wholesale? If it is substantial and the workflows are complex, BigCommerce's bundled B2B Edition saves you an app stack and custom work. If B2B is a growing side channel to a DTC core, Shopify Plus's unified model is cleaner.
• 02
  Are you locked to a non-Shopify payment gateway? If yes, Shopify's 0.20% third-party fee is a recurring tax. On $50M GMV that is $100K a year. BigCommerce Enterprise charges nothing on any gateway. Do this math first, because it is the largest single line most teams overlook.
• 03
  Do you run one brand or several? Multiple brands or regions managed centrally point to BigCommerce's native multi-storefront under one contract. A single flagship with a few international expansions fits Shopify's expansion-store model, especially if you already run an ERP or PIM.
• 04
  What is your team optimized for: speed or control? A lean team that wants to ship fast and buy functionality off the shelf is a Shopify team. An engineering-heavy team that wants open APIs, raw checkout access, and no revenue share is a BigCommerce team. Watch CLV and LTV:CAC through any migration, because a conversion dip during cutover can erase years of platform savings.
