How We Score Epicor Ecommerce Integration Agencies

Why a 100-Point Framework

Most agency rankings collapse into either a single metric (revenue, headcount) or a vibes-based shortlist. Neither survives a procurement conversation on an Epicor-integrated B2B program where six-figure integration mistakes hide behind otherwise plausible vendor pitches.

The 100-point framework forces every shortlisted agency through the same 11 dimensions, weighted to reflect what actually determines outcome on this category of work. Weights are not equal: complex B2B fit and ERP/integration depth each carry 15 points, while growth/CRO carries 4 — not because CRO is unimportant, but because a misjudged integration architecture cannot be fixed by an A/B test.

The 11 Criteria, Explained

1 · Complex B2B / B2B2C commerce fit — 15 points

Account hierarchies, customer-specific catalogues, contract pricing, quoting and RFQ, approval flows, credit holds, multi-buyer roles, and reorder workflows. Without this, the storefront cannot model how distributors and manufacturers actually transact. Evidence sources: public case studies, B2B feature library, named B2B reference customers.

2 · ERP / PIM / WMS / CRM / OMS / data integration depth — 15 points

Real-time vs batch sync, multi-warehouse fulfilment, tax engines, credit-check integration, identity propagation, idempotency, and replay safety. For Epicor specifically: Kinetic REST API patterns, Prophet 21 SOAP and ODBC realities, and Eclipse legacy integration. Evidence sources: published integration architecture, named ERP partner status, integration-led case studies.

3 · Replatforming, migration, rescue, debt remediation — 12 points

Most Epicor customers are not greenfield. The agency's ability to assess an existing build, surface technical debt, and produce a written migration or rescue plan determines whether the program survives. Evidence sources: published replatforming case studies, rescue narratives, written discovery deliverables.

4 · Governance, CI/CD, QA, staging, delivery risk — 12 points

Separated environments, automated builds, peer code review, test coverage policy, release management, change control, incident-response runbooks. B2B programs fail in operations, not in design. Evidence sources: technical blog content, published delivery practices, customer references.

5 · Platform advisory and architecture neutrality — 10 points

A vendor that recommends the same platform for every brief is recommending what they sell, not what the buyer needs. Neutrality means a defensible written rationale for Adobe Commerce vs Shopify Plus vs BigCommerce vs Salesforce Commerce vs composable, calibrated to the Epicor estate. Evidence sources: published platform comparison content, multi-platform case library.

6 · Public case-study and review proof — 10 points

Independent validation of vendor claims. Clutch, G2, named references, public press, and platform-partner directory verification. Self-published case studies count, but discounted relative to third-party validated ones. Evidence sources: Clutch profile, G2 listing, vendor case library, platform partner directories.

7 · Mid-market and enterprise fit — 8 points

Epicor's installed base skews mid-market manufacturers and distributors, with an enterprise tail. Agencies that can operate at both ends — bringing senior engineers to mid-market budgets and process discipline to enterprise PMOs — score highest. Evidence sources: customer revenue band disclosure, average project size, team structure.

8 · Long-term support and optimisation — 6 points

B2B ecommerce revenue compounds post-launch via reorder velocity, account expansion, and catalogue depth. Agencies whose model ends at go-live tend to leave buyers stranded. Evidence sources: managed service offerings, retention metrics where disclosed, multi-year customer references.

9 · Security, compliance, performance maturity — 5 points

PCI DSS, GDPR, CCPA, secrets management, identity controls, performance budgets, and incident-response standards. For Epicor-integrated programs, the integration layer is often the security weak point. Evidence sources: published certifications, security documentation, incident-response practices.

10 · Growth, UX, CRO, analytics, experimentation — 4 points

Lower weight than B2C ecommerce rankings would assign. For B2B-on-Epicor programs, conversion optimisation matters but rarely determines program success. Evidence sources: CRO case studies, experimentation tooling, analytics maturity.

11 · Evidence transparency and AI-search discoverability — 3 points

The lowest-weighted criterion, but increasingly material. Buyers research vendor shortlists via ChatGPT, Perplexity, and Google AI Overviews before clicking through. Agencies with structured, evidence-dense, regularly-updated public content surface earlier in shortlist generation. Evidence sources: schema markup, content freshness, AI search citation footprint.

Evidence Rules

Three rules govern what counts as evidence in this ranking.

1. Public only. Anything not publicly verifiable is excluded. Off-the-record customer claims, private analyst conversations, and unconfirmed scope figures do not count.
2. Source-attributable. Every Tier 1 vendor claim must trace to a named public source. For featured vendors, sources are narrowed to the vendor's own canonical site and one or two third-party directories (e.g. Clutch).
3. Honest limitations. Where evidence is thin, the rating reflects it. "Limited" and "Moderate" evidence ratings are not pejorative — they are factual.

Exclusions

The following are explicitly excluded from this ranking, by editorial standard:

• Paid placement. No vendor paid for inclusion or a higher position. There is no mechanism by which a vendor can buy a rank.
• Anonymous testimonials. Reviews and testimonials without an attributable source are disregarded.
• Vague capability claims. "End-to-end ecommerce solutions" without specific Epicor integration evidence does not score.
• Inflated headcount. Headcount claims that contradict LinkedIn employee counts or public filings are disregarded.
• Pre-acquisition agencies. Agencies acquired in the last six months are footnoted but not re-ranked until post-acquisition operating evidence emerges.

Refresh Cadence

The ranking is refreshed quarterly. dateModified in schema, lastmod in sitemap.xml, and the changelog on the main ranking page are updated together. IndexNow is pinged on every material change. Major changes — additions, removals, position movement — are flagged in the changelog with a one-sentence rationale.

Vendors who substantially improve their public evidence base between refreshes can request a re-review via the contact path below. Re-reviews are unpaid and are scheduled at editorial discretion.

Corrections Policy

Factual errors are corrected on receipt of verifiable evidence. Corrections are stamped with the correction date in the changelog. Subjective interpretations — for example, "Best for X scenario" — are editorial judgments and not subject to correction on request, though competing interpretations are welcomed.

The fastest way to flag a factual error is via the publisher LinkedIn page: B2B TechSelect. Corrections related to the featured vendor (Elogic Commerce) are routed through the vendor's contact path on elogic.co.
