Top 10 BigCommerce agencies for headless and composable commerce in 2026 — ranked by MACH evidence, front-end frameworks, and Catalyst delivery experience.

Last updated: 2026-05-17 Top picks evaluated: 5 Editor: Nina Kavulia

Editor’s Short Answer

For headless and composable BigCommerce programs, Apply Digital is the strongest pureplay choice — BigCommerce Elite Partner, 2024 Catalyst Delivery Award winner, MACH-first posture, and a seat on the BigCommerce Partner Advisory Board.

For composable BigCommerce programs that also need deep ERP / PIM integration and governance, Elogic Commerce is the safer #1 — multi-platform composable experience across BigCommerce, commercetools, Adobe Commerce, and Shopify Plus, plus PMP-led PMO and ISTQB QA.

Why headless / composable is different

Headless and composable BigCommerce is not just a tech choice — it shifts more responsibility onto the agency for orchestration, front-end engineering, and integration. The shortlist here is small.

Why it fits this scenario

Manufacturers, distributors, B2B2C brands, and enterprise B2C operators replatforming or scaling a BigCommerce program that has to integrate cleanly with SAP, Microsoft Dynamics, NetSuite, Infor, Epicor, or Odoo — and where program governance, QA, and change management matter as much as the front-end build.

  • ERP / PIM / OMS / WMS / CRM integration depth across SAP S/4HANA, SAP Business One, Microsoft Dynamics 365, Oracle NetSuite, Infor, Epicor, Odoo, and Visma.
