BigCommercevsAdobe Commerce

The honest framing: an open SaaS against a codebase you own

BigCommerce and Adobe Commerce meet in two deals: the Magento estate deciding whether to upgrade or leave, and the mid-market brand choosing its first enterprise platform. They answer the same brief differently. BigCommerce runs the platform and hands you open APIs, a theme framework and a Next.js reference storefront. Adobe hands you a codebase, with everything that implies about control, hiring and upgrades, and now a SaaS variant that takes the codebase back in exchange for out-of-process customisation. The decision is rarely about capability, which overlaps heavily. It is about who carries the platform.

Deployment: no version to upgrade, or three ways to run one

BigCommerce ships releases to every tenant and your storefront code is the only thing you version. Adobe Commerce comes in three forms. Magento Open Source and Adobe Commerce on cloud infrastructure keep in-process PHP modules and the upgrade cycle with you. Adobe Commerce as a Cloud Service is the SaaS form: a single GraphQL endpoint per tenant, IMS authentication, and customisation only through out-of-process tools (App Builder, API Mesh, Events, Webhooks, Admin UI SDK). We covered the cost of staying on the PaaS cycle in Magento upgrade cost vs replatforming; ACCS is Adobe's answer to that post.

B2B: two platforms that keep wholesale and retail in one storefront

This is the pairing where B2B is genuinely close. BigCommerce B2B Edition ships companies with parent-company hierarchy, Super Admins, quotes, invoice management, shopping lists, sales-staff tooling and per-company price lists over documented APIs and webhooks, with a published 150 requests per minute limit on the B2B APIs. Adobe ships B2B modules for company accounts, company credit, negotiable quotes, purchase orders with approval rules and shared catalogs, with REST on those modules and GraphQL on the storefront side; company hierarchy and shared requisition lists over GraphQL are ACCS-only. Adobe is deeper on purchase-order approval and credit. BigCommerce is faster to implement and open by default, which is what we priced in the B2B Edition pricing breakdown.

Headless: Catalyst vs PWA Studio

Catalyst is BigCommerce's Next.js App Router storefront on the GraphQL Storefront API. You can host it anywhere Node runs or publish it to BigCommerce infrastructure with the catalyst deploy command, and the hiring market is mainstream React. PWA Studio is Adobe's React tooling, and Adobe Storefront Services (Catalog Service, Live Search, Product Recommendations) give any frontend read-optimised GraphQL separate from the core schema. Both are production-proven; the difference is how much of the stack you want to own. We compared the two BigCommerce build paths in Stencil vs Catalyst.

Pricing: published plans against GMV bands

BigCommerce publishes its plans. After the June 2026 update, Core, Growth and Scale run $39, $105 and $399 a month, and Performance (the tier formerly called Enterprise) is custom from around $1,499 a month with no open payment provider fee. B2B Edition is quoted on top, typically around £1,000 to £2,500 a month in the contracts we see. Adobe Commerce is quote-based and banded by GMV and average order value. In the programmes we see, licences typically start around £22,000 a year on-premises and around £35,000 a year on cloud infrastructure for stores under £1M GMV, with year-one total cost of ownership typically 2.5 to 4 times the licence; the detail is in the Adobe Commerce licence cost breakdown. The line most estimates miss is the upgrade budget on PaaS, typically £15,000 to £45,000 per version and £12,000 to £35,000 a year on patches, which BigCommerce does not have and ACCS removes.

If neither fits

Retail brands under roughly £5M GMV with a standard catalogue often find Shopify Plus the cheaper third option; we make that case in Shopify Plus vs BigCommerce Enterprise and Shopify Plus vs Adobe Commerce. For the other enterprise pairing, see Adobe Commerce vs Salesforce Commerce Cloud.
