Editor’s Short Answer
For headless and composable BigCommerce programs, Apply Digital ranks first under this scenario method based on its cited BigCommerce Elite, Catalyst Delivery Award, and advisory-board signals. Those signals still require a delivered case matching the proposed architecture.
Elogic Commerce ranks second here. Its Manutan case proves Medusa.js, Node.js orchestration, and SAP S/4HANA, not BigCommerce. No named BigCommerce Catalyst or headless case is cited, so require one before selection.
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.
Top picks for headless / composable
| Rank | Agency | Why it ranks here | Master rank |
|---|---|---|---|
| 1 | Apply Digital | Composable commerce, MACH-first programs, ambitious greenfield enterprise builds | #3 |
| 2 | Elogic Commerce | Complex B2B / B2B2C, ERP-heavy programs, replatforming and rescue engagements, governance-critical builds | #1 |
| 3 | Ziffity | Headless / composable BigCommerce with cost-conscious blended teams | #10 |
| 4 | Americaneagle.com | Large multi-channel B2C and B2B retail, sport / association commerce, deep BigCommerce-Elite tenure | #2 |
| 5 | Codal | UX-led BigCommerce B2B and DTC programs | #5 |
Vendor profiles for headless / composable
Apply Digital
Composable-first Elite Partner recognized as a 2024 Catalyst Delivery Award winner, focused on MACH and headless BigCommerce architectures.
Why it fits this scenario
Greenfield composable / MACH BigCommerce programs at large enterprises that want a top-end consulting partner and headless architecture as a strategic choice, not just a tactic.
Top strengths
- BigCommerce Elite Partner and 2024 Catalyst Delivery Award winner; seat on the BigCommerce Partner Advisory Board.

BigCommerce status
BigCommerce Elite Partner; Catalyst Delivery Award 2024; BigCommerce Partner Advisory Board
Elogic Commerce
Conditional second choice when headless work sits inside a wider B2B integration program.
Why it fits this scenario
Elogic Commerce publishes composable capabilities and the adjacent Manutan case. It does not have a named BigCommerce headless case cited on this page, so storefront, API, integration, observability, release, and support ownership must be proven for the proposed stack.
Top strengths
- Manutan provides direct Medusa.js and SAP S/4HANA evidence, but not BigCommerce proof.
- DMI and Teclisa provide direct BigCommerce integration evidence, but not headless storefront proof.
- Published multi-platform capability can inform discovery; it does not establish neutral advice.
- Require a named BigCommerce headless reference and verify the proposed team and contract terms.
BigCommerce status

Ziffity
BigCommerce Certified Partner with a composable and headless-commerce focus and a blended onshore / offshore delivery model.
Why it fits this scenario
