Ratings and designations held on platforms EPC Group does not control, alongside one figure EPC Group reports itself — each labelled so you can tell which is which:
Documented client engagements. Every claim is tied to a source document. Nothing on these pages is asserted without an artifact. Each record publishes the source documents it relies on, states what those documents do not establish, and carries a SHA-256 hash for every published file.

EPC Group's ratings and designations are held on platforms operated by other organisations — G2, Trustpilot, Clutch and Microsoft.
Reported by EPC Group rather than by anyone else: 11,000+ enterprise implementations, counted from EPC Group’s own historical project records.
Those two groups are kept apart deliberately. The ratings and designations are maintained by other organisations and can be checked at the source; the engagement count is ours, and is presented as ours.
G2 awards are based on verified customer reviews — not vendor nominations or paid placements. EPC Group's G2 Leader status reflects what clients say after the project is complete.
Microsoft Solutions Partner status is verified directly by Microsoft. It is not self-reported. The six designations require active project delivery, customer satisfaction scores, and certified staff — reviewed annually.
EPC Group held Microsoft Gold Partner status from 2000 until Microsoft retired the program in 2022.
When Microsoft retired the Gold Partner program in 2022, EPC Group earned core Microsoft Solutions Partner designations on the same day.
EPC Group tracks six satisfaction metrics for every engagement. These are not aspirational targets — they are tracked per project and reported to clients.
Evidence is not just about volume. For regulated industries, compliance track record matters as much as implementation count.
We are recognized through various platforms for our excellence:

EPC Group provides references from healthcare organizations (HIPAA-regulated), financial services firms (FINRA/SEC-regulated), government agencies (FedRAMP environments), and educational institutions (FERPA-compliant).

EPC Group typically provides 3-5 references matched to the prospect's industry, project scope, and organizational size.
EPC Group tracks comprehensive client satisfaction metrics including G2 Leader status (six consecutive quarters), project delivery on-time rate (tracked per engagement), client retention rate (percentage of clients engaging for multiple projects), first-call resolution rate for managed services, SLA compliance metrics for support agreements, and post-implementation adoption rates. These metrics are reviewed quarterly by EPC Group leadership and shared with clients during quarterly business reviews.
