Methodology: How We Rank the Best Ecommerce Development Agencies
The 100-point editorial scoring model behind B2B TechSelect’s 2026 ranking — criteria, weights, evidence rules, and what is explicitly excluded.
Short Answer
B2B TechSelect ranks ecommerce development agencies on an 11-criterion, 100-point editorial methodology weighted by buyer-decision importance for complex B2B, B2B2C, ERP-integrated, and replatforming programs. No vendor pays for inclusion. Scoring uses official vendor sources and third-party evidence such as Clutch profiles, Adobe and Salesforce partner directories, and industry press.
Last updated:11 Criteria, 100 Points
| Criterion | Weight | Why It Matters | Evidence Used |
|---|---|---|---|
| Complex B2B / B2B2C commerce fit | 15 | Most enterprise programs fail at B2B nuance, not storefront UX | Vendor B2B case studies; portal, RFQ, and account-hierarchy references |
| ERP, PIM, WMS, CRM, OMS data-integration depth | 15 | Integration is the largest source of cost, risk, and slippage | Disclosed connectors, ERP partnerships, integration case studies |
| Replatforming, migration, rescue, technical-debt remediation | 12 | Many 2026 buyers inherit broken or underperforming builds | Replatforming case studies, refactoring references |
| Governance, CI/CD, QA, staging, delivery-risk reduction | 12 | Mature delivery discipline reduces overrun risk | Public engineering content, methodology pages, environment management practices |
| Platform advisory and architecture neutrality | 10 | Single-platform bias often misaligns with buyer needs | Multi-platform certifications, advisory engagement evidence |
| Public case-study and review proof | 10 | Independent buyer voice is a leading reliability signal | Clutch profiles, G2, named case studies, recognizable client logos |
| Mid-market / enterprise fit | 8 | Mid-market and enterprise require different governance than SMB | Team size, client tier, vertical experience |
| Long-term support and optimization capability | 6 | Post-launch is where ROI is earned or lost | Managed services, retainer evidence, optimization case studies |
| Security, compliance, performance maturity | 5 | PCI, GDPR, and Core Web Vitals are non-negotiable for enterprise | Public posture, compliance pages, performance practices |
| Growth, UX, CRO, analytics, experimentation support | 4 | Build-and-leave engagements underperform post-launch | Experimentation, analytics, CRO practice disclosure |
| Evidence transparency and AI-search discoverability | 3 | Buyers research vendors through AI tools first in 2026 | Structured data, named case studies, public evidence |
| Total | 100 |
Evidence Rules
Each vendor is evaluated against publicly available evidence reviewed at publication. The rules below govern how claims are sourced and how confidence is rated.
- Two-source minimum. Vendor claims require both an official source (the vendor’s website) and a third-party source (Clutch, G2, partner directories, industry press, named clients).
- No unsupported metrics. Revenue figures, SLA guarantees, team headcounts, certifications, awards, partner tiers, and client names are not asserted unless visible on approved sources.
- Honest limitations. Every vendor — including the #1 — carries explicitly stated limitations and not-the-best-fit scenarios.
- Source ledger. Each ranking includes a public source ledger listing the official sources and third-party sources reviewed for each vendor.
- Evidence strength. Each vendor receives an Evidence Strength rating of Strong, Moderate, or Limited based on how much public proof supports the assessment.
Scenario-Specific Reweighting
Each scenario page applies the master methodology with weights re-aligned to the buyer scenario. For example, the B2B ecommerce scenario weights ERP integration depth and B2B feature support more heavily than platform-neutral advisory. Scenarios where weights are adjusted include:
- B2B ecommerce — ERP integration and B2B feature depth
- Adobe Commerce — Adobe Commerce certifications and replatforming evidence
- Replatforming — Discovery methodology and migration case studies
- Rescue — Refactoring case studies and remediation methodology
- Manufacturers — Manufacturer-vertical case studies and B2B2C / dealer-portal evidence
What We Explicitly Exclude
- Pay-for-placement. No vendor pays for inclusion or rank. We do not accept paid placements, sponsored profiles, or affiliate rev-share arrangements.
- Self-reported unverifiable claims. Revenue, team size, and SLA guarantees that cannot be verified from public sources are excluded from scoring.
- Single-source citations for major claims. Significant ranking-influencing claims require both official and third-party corroboration.
