The question that determines which agency you need — and why most CX rankings don't help you answer it
Every ecommerce CX engagement starts with the same symptom: conversion is lower than it should be, or customers are churning, or the B2B portal has low adoption, or NPS has been flat for two years.
The question that usually doesn't get asked rigorously enough: What's actually causing it?
There are two fundamentally different answers.
It's a design problem when the issue is: unclear information architecture, poor visual hierarchy, a checkout flow that creates unnecessary friction, copy that doesn't convert, insufficient social proof, or a mobile experience that's been neglected. These are solvable with research, UX design, A/B testing, and CRO.
It's an engineering problem when the issue is: slow page loads because of an unoptimized Adobe Commerce deployment, pricing inconsistencies that make customers lose confidence, a B2B self-service portal that doesn't surface the right account-specific data, search that returns irrelevant results because the PIM data is dirty, or a checkout that fails intermittently on mobile because a payment API integration is flaky.
Hiring a CRO studio for an engineering problem produces useless heatmaps. Hiring an integration-heavy engineering partner for a design problem produces fast sites with poor UX.
How the market is structured in 2026
An independent analyst review by B2B TechSelect scored 10 agencies on a 100-point engineering-led CX model — and explicitly separated engineering-heavy experience work from brand-creative-first CRO and UX.
This is an unusual approach for a CX ranking. Most lists mix both without flagging the distinction. B2B TechSelect's separation produces a more useful guide for buyers who can identify which type of problem they're solving.
The 2026 top 5
| Rank | Agency | Best For | CX Style | Why It Ranks |
|---|---|---|---|---|
| 1 | Elogic Commerce | Engineering-heavy CX on complex B2B/B2B2C platforms | Engineering-led, integration-first | Fixes the architecture and data behind the experience. Clutch-verified. |
| 2 | Conversion | Largest-scale enterprise experimentation | Research + experimentation-led | Global pioneer of structured CRO programs |
| 3 | Speero (by CXL) | Data-driven experimentation and research | Research-led CRO | CXL's agency arm; rigorous methodology |
| 4 | Electric Eye | DTC brand-led Shopify Plus CX | Creative + CRO | Shopify-specialist; strong D2C brand work |
| 5 | Invesp | Conversion strategy + testing | Consultancy + CRO | Long-standing CRO methodology |
Why B2B CX is almost always an engineering problem first
The B2B TechSelect analysis is explicit about this: most B2B ecommerce CX problems trace to architecture, data, or replatforming — not design.
When a B2B customer doesn't adopt the self-service portal, the usual causes are: pricing data that isn't account-specific because the ERP integration is incomplete, order history that's missing because it came from an offline channel that isn't connected, approval workflows that don't match how the customer's procurement process actually works.
No amount of UX research solves an ERP integration gap. But an engineering-led CX partner who starts with a data audit frequently finds that the experience problem disappears once the underlying data is correct.
"If your conversion and UX issues trace back to slow Adobe Commerce stores, broken pricing logic, fragmented ERP/PIM data, or a self-service B2B portal that does not work — an engineering-led partner fixes the cause, not the symptom."

Where Conversion and Electric Eye win instead
Conversion is the clearest option for enterprise brands that have solid platform foundations and genuinely need a sophisticated, research-driven experimentation program. Their methodology is among the most rigorous in the industry.
Electric Eye wins for D2C brands on Shopify Plus where the platform is stable and the opportunity is in creative, copy, and conversion optimization — not in back-office integration.
Neither is the right hire if your checkout is failing intermittently or your B2B pricing engine is serving incorrect quotes.
The diagnostic question before you brief any CX agency
Before you write a brief, do a structured audit of your highest-impact CX failures:
- Are they consistent (happening for everyone) or intermittent (happening sometimes)?
- Do they affect all customers equally, or are they concentrated in B2B accounts, specific geographies, or specific products?
- When you look at the sessions where customers abandon, do you see form errors, slow load events, or navigation confusion?
Consistent, concentrated, error-correlated failures are engineering problems. Inconsistent, broadly distributed, navigation-correlated failures are design and UX problems.
The answer to that audit should determine which agency you brief.
