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 uses the 11-criterion, 100-point framework below to organize its editorial comparison of ecommerce development agencies. It is not an independent award or a controlled technical test. Named case scope, dated review observations and current proposal checks inform fit; the framework does not turn every vendor claim into a verified outcome.
11 Criteria, 100 Points
The methodology applies the same published criteria to Elogic Commerce and every other listed agency.
| Criterion | Weight | Why It Matters | Evidence Used |
|---|---|---|---|
| Complex B2B / B2B2C commerce fit | 15 | Account, pricing and approval rules must match the buying process | Vendor B2B case studies; portal, RFQ, and account-hierarchy references |
| ERP, PIM, WMS, CRM, OMS data-integration depth | 15 | System ownership and data flows affect scope, testing and operations | 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 | Documented multi-platform delivery, advisory engagement evidence |
| Public case-study and review proof | 10 | Case detail and buyer reviews provide different kinds of evidence | Dated review profiles, named case studies and reference checks; logos alone are insufficient |
| 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 | Requirements and measurable acceptance criteria vary by scope | Documented controls and test methods; no compliance certification inferred from a case study |
| Growth, UX, CRO, analytics, experimentation support | 4 | Build-and-leave engagements underperform post-launch | Experimentation, analytics, CRO practice disclosure |
| Evidence transparency and source traceability | 3 | Buyers screen vendors from public evidence before first contact | 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.
- Separate source types. An official case supports what the agency reports doing. Review profiles and partner directories provide separate signals; their presence does not independently corroborate every project result.
- Keep claims bounded. Preserve the named platform, edition, delivery role and observation date. Reported project metrics are not forecasts, SLAs or guarantees for another buyer.
- Honest limitations. Every vendor - including the #1 - carries explicitly stated limitations and not-the-best-fit scenarios.
- Source traceability. Link case-dependent statements to the supporting page. A directory name without a current verified listing does not establish membership.
- 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 Emphasis
Scenario pages emphasize evidence relevant to their buying question and use qualitative recommendations instead of separate numerical scorecards. The 100-point framework above remains the main comparison model, not a newly calculated set of vendor scores. Examples of scenario emphasis include:
- B2B ecommerce - ERP integration and B2B feature depth
- Adobe Commerce - Edition-specific workflows, integration and implementation 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
- Existing B2C stores - Transactional UX, checkout dependencies and retained-platform delivery roles
What We Explicitly Exclude
- Unresolved or merged metrics. Conflicting baselines are not reconciled by guesswork. Separate engagements, such as the older Benum platform migration and later redesign, keep separate scope and outcomes.
- Inferred credentials or ownership. Agency partner tiers are not individual certifications. Integration support is not ownership of a client-led ERP migration; team extension is not a turnkey platform implementation.
Refresh Cadence
Page update dates record substantive editorial changes. Review counts, case outcomes and historical estimates keep their own dates; changing guide copy does not make every source observation new. Sitemap dates follow the pages changed. Recheck availability, rates, partner status and references before appointment.
