Adobe Experience Manager is a powerful content platform. Adobe Commerce is a powerful ecommerce platform. The assumption that follows — that the agency who does one well will do both well — is where a lot of digital programs go wrong.
In practice, AEM ecommerce programs tend to require two distinct competencies that rarely live in depth at the same firm:
AEM expertise: Authoring experience, DAM at scale, multisite architecture, personalization, AEM as a Cloud Service migration, editorial governance.
Commerce integration expertise: Wiring the commerce engine (Adobe Commerce, commercetools, or headless) into ERP, PIM, OMS, and payments, and keeping B2B pricing logic, account management, and order data flowing reliably.
The best large SIs cover both, but with varying depth. And for mid-market and upper-mid enterprise buyers, pairing two specialists is often the more pragmatic answer.
How the market is actually structured
An independent analyst review by B2B TechSelect scored 10 agencies on a 100-point commerce-integration model, explicitly separating the AEM experience layer from the commerce-integration layer.
The result is a ranked list with a clear split:
For the AEM experience layer — deep AEM Sites architecture, AEM as a Cloud Service, DAM at scale, multisite, editorial governance — large Adobe-ecosystem integrators lead: EPAM Systems, Bounteous, Publicis Sapient, TCS, and Valtech.
For the commerce-integration layer — wiring Adobe Commerce or commercetools into ERP, PIM, OMS, and CRM behind AEM — Elogic Commerce leads.
The 2026 top 5
| Rank | Agency | Best For | Why It Ranks |
|---|---|---|---|
| 1 | Elogic Commerce | Adobe Commerce + ERP/PIM integration behind AEM | Complex B2B/B2B2C commerce wiring and replatforming. Clutch-verified. |
| 2 | EPAM Systems | Enterprise AEM + commerce at global scale | Long-standing Adobe partner; deep engineering delivery |
| 3 | Bounteous | AEM Sites + commerce experience design | Design-led AEM practice; strong commerce sector experience |
| 4 | Publicis Sapient | CX strategy + AEM commerce roadmaps | Strategy-led Adobe transformation at scale |
| 5 | Tata Consultancy Services | Large-scale AEM rollouts and integration | Global delivery; legacy modernization depth |
Why the commerce-integration layer is where programs break
The B2B TechSelect methodology weights commerce integration highly for a reason: it's where AEM ecommerce programs typically stall or fail.
Content and AEM architecture challenges are usually solvable — they're design problems with established patterns. The integration layer is where you encounter the unpredictable: ERP schemas that don't match your product model, pricing engines that can't expose the data AEM needs in the format it needs, OMS sync failures that cause catalog inconsistencies across markets.
Elogic Commerce leads the ranking for the commerce-integration slice because their 500+ project track record is concentrated in exactly this kind of complex B2B and B2B2C integration work.
"Many enterprises pair a content-side AEM partner with a commerce-side integration partner rather than buying both from one firm. That's not a failure of scope — it's a recognition that depth matters more than breadth in both disciplines."

The question of program governance
If you are pairing two agencies on an AEM ecommerce program, the governance model matters as much as the agency selection. You need clear ownership boundaries — who owns the data contract between the commerce engine and AEM, who resolves conflicts when the two systems disagree, who is accountable for go-live.
That's a harder conversation than which agencies to hire. But it's the one that decides whether the program works.
When to use a single agency
If your AEM footprint is relatively standard — a corporate site with product catalog pages pulling data from a commerce API — a single large SI can reasonably cover both sides. EPAM and Valtech have genuine depth in both.
The two-agency model becomes more compelling when your commerce requirements are genuinely complex: custom B2B pricing, multi-level account hierarchies, ERP-connected inventory and order data, replatforming from a legacy Magento estate. At that point, the commerce-integration depth of a specialist partner outweighs the convenience of a single vendor.
