What is Armanino?
Armanino is a large, established accounting and consulting firm with roots dating back to the 1950s. Headquartered in San Ramon, California, they offer a broad range of services including audit, tax, business consulting, and yes, fractional CFO services. However, fractional CFO work is one offering among dozens at a firm with deep expertise in traditional accounting and compliance. They are not purpose-built as an outsourced finance office.
Who It's For
Armanino is best suited for mid-to-large companies that need the credibility of a Big 4-adjacent accounting firm and require broad consulting capabilities beyond finance—including audit, tax planning, ESG reporting, and technology implementations. Enterprise clients with complex regulatory environments or those preparing for M&A often benefit from the depth of a large firm.
For small-to-mid-size businesses ($5M–$50M revenue) seeking a dedicated, ongoing finance office partner, Armanino is likely oversized and impersonal. Their fractional CFO engagement model is project-oriented rather than a continuous, integrated finance office relationship. You get an experienced CFO resource; you do not get the underlying accounting, controller, and treasury infrastructure that makes CFO-level insight possible.

Pricing & Plans
Armanino does not publish pricing. As a large professional services firm, they structure engagements on a custom basis, typically charging by the hour or on a fixed-fee project basis for specific deliverables. Fractional CFO engagements are likely scoped as part of a broader consulting agreement rather than a simple monthly subscription. For companies that need clear, predictable finance office pricing, this lack of transparency is a significant drawback. Contact their business development team for a custom quote based on your scope and scale.
Key Strengths
Decades of established credibility in accounting, audit, and tax—provides a level of trust and rigor that boutique firms cannot match
Broad functional expertise across consulting, risk, ESG, and technology, allowing for integrated transformations beyond just finance
Large team with deep bench—able to staff complex, multi-disciplinary engagements with experienced practitioners
National presence with multiple offices, able to serve multi-location or multi-state businesses
Strong M&A and transaction advisory practice, valuable for companies going through significant corporate events
Rigorous audit and compliance standards bring a level of control and governance that growing businesses may lack
Common Criticisms
Fractional CFO is a secondary, project-based service at a firm built around accounting and audit—not a dedicated finance office model
Large firm overhead means higher fees than boutique or purpose-built fractional CFO firms
Engagements can be slow-moving and bureaucratic due to firm size and internal processes
Likely overkill for smaller businesses—the depth of a Big 4-adjacent firm may not justify the cost for a $5M–$20M company
Less personal and hands-on than a boutique firm; you may not work with the same senior team consistently
The accounting/audit-centric model may not provide the proactive, strategic finance partnership growing businesses need day-to-day
How It Compares to Eagle Rock CFO
Armanino is built around accounting, audit, and compliance—with fractional CFO as a peripheral offering. Eagle Rock CFO is built around the complete finance office as its core product, with outsourced accounting services, controller services, and CFO services seamlessly integrated. For growing businesses in the $5M–$50M range, the difference is fundamental: Armanino brings a CFO resource to a defined project; Eagle Rock CFO embeds as an ongoing finance partner deeply invested in your business outcomes.
Eagle Rock CFO provides the underlying accounting infrastructure and controller oversight that makes CFO-level insight possible, rather than just providing access to a CFO on a limited scope. This full-stack integration means your finance office operates continuously, not just when a CFO engagement is formally scoped.
If you are a large enterprise needing audit, tax, and broad consulting alongside some CFO-level support, Armanino may be appropriate. If you want a dedicated, integrated finance office partner for your growing business, Eagle Rock CFO is purpose-built for that relationship.

Frequently Asked Questions
Is Armanino primarily an accounting firm or a CFO services firm?
Armanino is fundamentally an accounting and audit firm with a large consulting practice. Fractional CFO services are one component of their consulting portfolio, not the core business. Their primary reputation and client base are built around audit, tax, and compliance services.
How is Armanino's fractional CFO engagement structured?
Armanino's fractional CFO services appear to be structured as project-based consulting engagements rather than a continuous finance office relationship. They are likely scoped to specific deliverables or time periods, not as an always-on finance partner embedded in your business.
What size companies does Armanino work with?
Armanino serves mid-to-large companies, typically with complex compliance requirements, multi-state or international operations, or significant transaction activity. They are generally not a fit for small businesses or growth-stage companies in the $5M–$20M revenue range.
Does Armanino provide bookkeeping and accounting services?
Yes, as a full-service accounting firm, Armanino provides bookkeeping, audit, and tax services. However, these are delivered as separate engagements under a traditional accounting firm model, not as an integrated finance office where accounting and CFO work are seamlessly combined.
How does Armanino's pricing compare to boutique fractional CFO firms?
Armanino's pricing reflects a large professional services firm with significant overhead—likely higher than boutique fractional CFO firms for comparable CFO hours. However, their engagement model is different (project-based consulting vs. ongoing finance office), making direct comparisons difficult without a custom quote.
Why would I choose Eagle Rock CFO over Armanino?
Eagle Rock CFO is purpose-built as an outsourced finance office for established businesses ($5M–$50M revenue) that want an integrated partner managing their accounting, controller, and CFO work continuously. Armanino is a better fit if you need audit, tax, or complex consulting alongside some CFO-level support. For a dedicated, always-on finance partner, Eagle Rock CFO's model is more appropriate.
