Last updated by Errin O'Connor, Founder & Chief AI Architect, EPC Group
Pre-paid Consulting Blocks are a productized purchasing model: pre-purchase 40 or 80 hours of senior consultant time at the senior consultant anchor rate, then draw down over 6-12 months for advisory + implementation work. Better than fixed-fee accelerators when scope is uncertain or advisory-heavy. Better than T&M for predictable spend, rate lock, no scope-creep tax, bench continuity, simpler PO/accounting, vendor discipline. Common use cases: executive advisory, Copilot governance advisory, Purview taxonomy evolution, architecture review, board workshops, M&A integration advisory, compliance audit prep.

Pre-Paid Consulting Blocks FAQ
What are pre-paid Consulting Blocks?
Pre-paid Consulting Blocks are a productized purchasing model for Microsoft consulting services: a client pre-purchases a defined block of senior consultant hours (typically 40 or 80 hours) at an anchor rate, then draws down the block as needed over 6-12 months for scoped advisory + implementation work. Think of them as a hybrid between fixed-fee accelerators (defined scope, defined price, defined outcome) and time-and-materials (open scope, hourly billing). Consulting Blocks work best for: (1) Advisory work where scope evolves over time (roadmap development, architecture review, decision support). (2) Point-in-time deep-dives (workshops, one-off assessments). (3) Ongoing tuning or optimization where full retainer is over-scoped. (4) Post-implementation support where fixed-fee scoping is uneconomic. EPC Group Consulting Block anchor rates: a senior consultant anchor rate for senior consultant time, with block tiers at 40 hours ($7K-$7,400) and 80 hours ($14K-$14,800).
When should I choose a Consulting Block vs a fixed-fee accelerator?
Six triggers for Consulting Blocks over fixed-fee accelerators: (1) Scope uncertainty at start — you know the general problem but not the specific deliverables. (2) Advisory-heavy engagement — architecture review, roadmap development, executive workshops. (3) Small scope — under 80-100 hours of effort, doesn't justify accelerator overhead. (4) Point-in-time deep-dives — one-off Copilot readiness check, one-off Purview label taxonomy review. (5) Post-accelerator support — after a fixed-fee accelerator, ongoing Q&A + tuning fits Blocks. (6) Scope creep expected — flex up or down as engagement evolves. Six triggers to use fixed-fee accelerator instead: defined deliverables, budget approval needs upfront certainty, buyer wants delivery accountability (fixed-fee firm owns overrun cost), scope over 100 hours, cross-team engagement, executive sponsorship needs milestone commitments.
When should I choose Consulting Blocks vs time-and-materials?
Six reasons Consulting Blocks beat T&M every time except one: (1) Predictable spend — block is pre-paid, no month-end surprise. (2) Rate lock — anchor rate is protected for the block duration, not subject to mid-engagement rate increases. (3) No scope-creep tax — buyer discipline enforced by finite block. (4) Bench continuity — block includes named consultant commitment, not rotating who's available. (5) Simpler purchase order + accounting — one PO covers 6-12 months of work. (6) Vendor discipline — consulting firm can't inflate hours because block has fixed size. The one exception where T&M might win: extremely large scope where hourly precision matters over engagement predictability, and the buyer has strong internal governance to prevent hour inflation. In practice, this is rare; almost always Consulting Blocks or fixed-fee accelerators are better than T&M.
How is a Consulting Block structured?
Seven Consulting Block structural elements: (1) Block size - a 40-hour or an 80-hour block at the senior consultant anchor rate. (2) Consumption period — typically 6 months for 40-hour blocks, 12 months for 80-hour blocks (extend by mutual agreement). (3) Named senior consultant assignment — one named consultant is your primary; escalation to specialist consultants (Copilot / Purview / Fabric / Defender / Sentinel) as scope requires. (4) Consumption tracking — monthly usage report + running balance. (5) Scope guidelines — what block work covers (advisory, workshops, architecture review, small implementations) vs excludes (large migrations, coding-heavy work — those need fixed-fee accelerators). (6) Deliverable format — written summaries + decision docs + presentations as appropriate. (7) Renewal or roll-over — unused hours may extend at anniversary or roll into next block (per client-specific terms). Buyers appreciate the productized purchase experience — single PO, single invoice, single accounting line item.
What are common Consulting Block use cases?
Seven common Consulting Block use cases: (1) Executive advisory — quarterly CIO/CDO/CISO advisory conversations, decision support, market intel. (2) Copilot governance advisory — ongoing tuning of sensitivity labels, DLP policies, Conditional Access as new Copilot capabilities ship. (3) Purview taxonomy evolution — as your organization matures, labels + retention + DLP need periodic refinement. (4) Architecture review — quarterly review of Fabric F-SKU consumption + Power BI Premium capacity + Copilot licensing. (5) Board-level workshops — one-off preparation for board technology committee. (6) M&A integration advisory — during acquisition, ongoing advisory on tenant consolidation strategy. (7) Compliance audit prep — HIPAA / SOC 2 / FedRAMP / CMMC audit preparation and evidence gathering. Consulting Blocks let the buyer engage senior EPC Group expertise for these situations without the accelerator overhead.
What is the EPC Group Consulting Block anchor rate?
Consulting Blocks are sold at the EPC Group senior consultant anchor rate. EPC Group does not publish that rate; it is confirmed after a scoping call. Two tiers: a 40-hour Block and an 80-hour Block. The block price is the anchor rate multiplied by the block hours. Rate variance depends on regulated-industry premium (HIPAA / SOC 2 / FedRAMP / CMMC engagements at the upper anchor) vs commercial (at the lower anchor). For context, published industry benchmarks put Big Four blended rates at $400-$650/hour, Global SI blended rates (Accenture / Avanade / Slalom) at $350-$525/hour, and offshore delivery at $85-$170/hour; boutique specialists price below the large integrators. The EPC Group senior consultant anchor sits at the value end of the boutique specialist band while delivering all six Solutions Partner designation expertise and senior consultants with 15-20+ years of continuous Microsoft delivery.
How does Errin O'Connor position Consulting Blocks vs T&M?
Errin O'Connor (Founder & Chief AI Architect, EPC Group) has consistently advocated for productized purchasing models over time-and-materials since founding the firm in 1997. The Consulting Block model reflects six operating principles: (1) Predictable spend enables predictable engagement — buyers don't need to escalate for every hour. (2) Bench continuity — named consultant means real accountability. (3) Vendor discipline — finite block prevents scope inflation. (4) Advisory work is valuable — but only if easily consumable in packages that match budget cycles. (5) Senior-only delivery — no junior-heavy T&M engagement where buyers subsidize junior training. (6) 29 years pattern-matching — Consulting Blocks emerged from watching thousands of engagements fail on T&M open-scope arrangements.
