More than 90% of VC-backed startups that reach Series A are running on outsourced or fractional finance - which means the CFO firm you choose is a competitive variable in your raise, not just an operational one.

This post compares three firms founders frequently evaluate together: CFO Advisors, Burkland, and Acuity. Each has real strengths. The right choice depends on your stage, what your investors will scrutinize, and how deep the work needs to go.

Who This Comparison Is For

This breakdown is most useful if you are:

• Post-seed or Series A, with $1M-$20M in ARR
• Preparing for a fundraise in the next 6-18 months
• Running finance on a part-time or outsourced team
• Evaluating firms on fundraising readiness, not just compliance and reporting

If you are earlier stage and focused purely on bookkeeping, see our post on when to hire a fractional CFO.

Quick Overview

CFO Advisors is a strategic-first fractional CFO firm built for VC-backed startups. The team includes finance executives from Oracle and Stanford Graduate School of Business. It serves as the preferred fractional CFO firm of several tier-1 venture firms and has supported roughly 100 active clients through approximately $800M in fundraising.

Burkland is one of the largest fractional finance firms in the startup ecosystem. It offers fractional CFO, controller, accounting, and HR/people ops under one roof. Well-recognized in Silicon Valley and among investors who have seen its name on client cap tables.

Acuity is an outsourced accounting and fractional CFO firm based in Atlanta. Strong bookkeeping and controller capabilities, expanded upmarket into fractional CFO services. Broader client base that includes both startups and SMBs.

Side-by-Side Comparison

CFO Advisors: Deep Dive

CFO Advisors is differentiated by what it does before touching a model: it starts with a strategic plan.

Across roughly 90 portfolio companies, the pattern is consistent. Nearly every startup plan follows the same template - hit $1M, hit $5M, hit $20M, add PLG, add SLG, land and expand. The problem is that template has never actually worked at most of those companies. CFO Advisors defines 1-2 objectives per horizon, the explicit sequence of bets, and a deprioritization list. That last piece - the list of what you are not doing - is what makes a plan fundable. Investors can hold you accountable to it.

From there, the financial model is built backward from the growth target. What pipeline, new logos, ACV, and headcount gets you there? That is a model investors can underwrite. It is not a spreadsheet with five scenarios that all converge to the same revenue number by year three.

The engineering layer. CFO Advisors is the only fractional CFO firm with an in-house engineering team. That team builds a proprietary data pipeline that connects CRM, HRIS, billing, and spend management. Reporting is pushed to every stakeholder via Slack in real time, at whatever cadence the team sets. No waiting six weeks after month-end to learn what happened in February.

The deeper point is what happens when the data is wrong. At most fractional finance firms, bad data gets reported accurately - the firm tells you your ARR reconciliation is off and leaves it there. CFO Advisors fixes the underlying system. That might mean adding fields to the CRM to capture revenue correctly, linking HRIS to expense management, or fixing process governance so the same error does not recur every quarter. In diligence, that distinction is material. Investors see clean data with a clear paper trail, or they do not.

Operational framework. CFO Advisors runs an operational excellence framework built around five principles: Transparency, Alignment, Accountability, Autonomy, and Velocity. The goal is to double organizational speed, not just report on it. One strategic finance decision creates 100 downstream operational decisions. A CFO who only reports on those decisions is not creating leverage. A CFO who shapes them is.

VC relationships. Being the preferred firm of tier-1 venture firms is not a marketing claim. It reflects a track record vetted by investors with the most at stake in finance quality. When you raise, your investor and your CFO firm often already know each other. That reduces friction in diligence and speeds up the process of building investor confidence.

For more on how CFO Advisors compares in a broader field, see our CFO Advisors vs Pilot vs Burkland breakdown.

Burkland: Deep Dive

Burkland is a serious firm with real scale. It has grown significantly and has brand equity among startup investors and operators in the Bay Area. Founders who need a single vendor for CFO, accounting, and people operations will find all of that at Burkland without coordinating multiple providers.

The core CFO offering is model-driven: Burkland will build and maintain your financial model, run board reporting, and support fundraising with financial preparation. That covers a lot of what a Series A founder needs.

Where Burkland is strong:

• Breadth. If you need a fractional CFO, a controller, and people ops from one provider, Burkland can staff all three without creating coordination overhead.
• Staff depth. Burkland has enough people to cover transitions without service gaps. Turnover at a smaller firm can create meaningful interruption.
• Brand recognition. Some investors view Burkland's name on a finance team as a signal of operational maturity.
• Accounting quality. The bookkeeping and controller layer is a genuine strength, particularly for companies navigating revenue recognition complexity.

Where Burkland has limits:

• The model is built for reporting, not for fixing the systems that generate data. If your CRM is misaligned with your billing system, Burkland reports the discrepancy. Resolving it is your problem.
• Strategic planning is not the core product. Burkland CFOs are strong financial operators. Challenging the strategic plan itself, or helping define the sequence of bets, is not what the firm is built for.
• No engineering infrastructure. Real-time automated reporting and data pipeline work are not part of the standard offering.
• VC warm intros are more limited than what a firm with deep portfolio company relationships can offer.

Burkland is the right fit for companies that need accounting depth, staff consistency, and operational breadth - and are not yet in the phase where strategic fundraising preparation is the primary deliverable.

Acuity: Deep Dive

Acuity built its reputation on accounting. It is a bookkeeping and controller firm that has added fractional CFO services as clients have grown. Its Atlanta base reflects a broader geographic scope than the Bay Area-centric competitors.

Where Acuity is strong:

• Accounting depth. Clean books are Acuity's core competency. If you are pre-seed or seed stage and need reliable accounting plus part-time board reporting, Acuity delivers that consistently.
• Price point. Acuity is generally the least expensive option among the three, which matters when you are managing runway carefully.
• Technology integrations. Acuity works well across common startup accounting stacks - QuickBooks, Xero, and similar tools - and handles integrations without friction.
• Accessibility. Acuity's client base is diverse, which means the onboarding process is well-documented and the support team is responsive.

Where Acuity has limits:

• Strategic advisory is limited. Acuity was not built to challenge your go-to-market assumptions, pressure-test your unit economics narrative, or help you build a fundraising strategy. If your lead investor asks hard questions about burn efficiency or cohort payback periods, Acuity is unlikely to be the firm sitting next to you in that conversation.
• No VC network. Acuity does not have the investor relationships that accelerate intros or build credibility before a raise.
• No engineering layer. Real-time reporting is not part of the offering.
• The fractional CFO product is an extension of an accounting firm, not a purpose-built finance leadership function.

Acuity is the right fit for companies at the earliest stages that need accounting rigor before they need strategic finance. Once you are preparing for a Series A - typically when ARR is approaching $1M-$3M - the gap between what Acuity offers and what you need will start to show.

Pricing

None of these firms publish standard pricing publicly. Engagements are scoped based on company stage, ARR, complexity, and the level of CFO involvement required.

A few notes on interpreting these ranges:

Burkland and Acuity typically price by hours or service tiers. CFO Advisors prices by scope and outcome, which means the engagement can be structured around a raise, a specific initiative, or an ongoing strategic retainer. The right comparison is not the monthly fee - it is the output.

Lower price does not mean lower cost. A cheaper firm that produces data investors cannot trust will cost you far more in dilution, delayed closes, or a down round than the price differential between these options. According to SaaS Capital research, companies with strong financial reporting and clear strategic plans consistently raise at better valuations than peers at the same ARR stage. Finance is not overhead. It is leverage.

The question is not "what can I afford?" The question is "what does a weak finance function actually cost me in this raise?"

What to Ask Any Fractional CFO Firm

Before you sign an engagement, ask four questions to every firm you evaluate:

1. What does onboarding look like, and how long before board-quality reporting is live?
2. When the data is wrong, do you fix the source system or report the problem?
3. Can I speak with three founders who have raised a round while working with your firm?
4. Does your CFO start from the strategic plan or from the model?

The answers to questions 2 and 4 will tell you almost everything you need to know about what category of firm you are evaluating.

The OnlyCFO newsletter has written extensively on what differentiates high-performing finance functions at each funding stage. The consistent finding is that strategic involvement from the finance function - not just reporting accuracy - is what correlates with better raise outcomes.

A Note on Third-Party Research

OpenView Partners and a16z have both published frameworks for evaluating startup finance functions. The consensus in both is that finance leadership quality compounds: a strategic CFO early creates capital efficiency advantages that persist through subsequent rounds.

Y Combinator's library consistently emphasizes that investors read your finance function as a signal during diligence, often before they read the deck. A CFO firm with VC credibility, clean data infrastructure, and a track record of raising capital alongside founders is part of how that signal gets communicated.

A Note on Authorship

This comparison was written by CFO Advisors. We have an obvious interest in how we are represented here. We have tried to describe Burkland and Acuity accurately - both are legitimate firms with real clients and real strengths. Before you make a decision, request references from any firm you evaluate and speak with founders who have used each. Take firm-authored comparisons as one data point, not the final word.

FAQ

What is the biggest difference between CFO Advisors and Burkland?

The core difference is strategic depth versus operational breadth. CFO Advisors starts with a strategic plan before building a model, has an engineering team for real-time data infrastructure, and is organized around fundraising outcomes. Burkland offers more services under one roof - accounting, people ops, and finance - but the CFO work is more execution-focused than strategy-focused. If you need a single vendor for everything, Burkland is the stronger choice. If you need a CFO who will challenge your plan and prepare you to raise, CFO Advisors is.

Is Acuity a good choice for a Series A startup?

Acuity is best suited to pre-seed and seed-stage companies. By Series A, most investors expect a finance function that can answer strategic questions - unit economics, cohort analysis, burn efficiency, capital allocation sequencing. Acuity's strengths are in accounting accuracy and bookkeeping, not strategic finance advisory. Founders who are approaching Series A and currently using Acuity typically need to upgrade before they enter diligence.

How do I evaluate a fractional CFO firm before signing?

Ask four questions: What does onboarding look like and how long before reporting is live? When data is wrong, do you fix the source system or report the problem? Can I speak with three founders who have raised while working with your firm? Do you start from the strategic plan or the model? The answers to questions two and four separate firms that are fundamentally different in their approach.

Does it matter if my fractional CFO has VC relationships?

Yes - particularly at Series A and beyond. VC-familiar CFO firms have seen more diligence processes, know what questions investors will ask, and help you prepare the right answers in advance. Some firms have relationships that can accelerate introductions. At seed stage, this matters less. At Series A, where investor confidence in your team and your data is a gating factor, it matters a great deal.

What should a fractional CFO cost at the Series A stage?

Expect $8,000-$15,000 per month for a strategic fractional CFO engagement at Series A. Cheaper options exist, but they typically cover accounting and reporting, not strategic planning and fundraising preparation. The cost of a weak finance function - in dilution, in delayed closes, in investor trust that is hard to rebuild once lost - consistently exceeds the price differential between these options.

How long does it take to see results from a fractional CFO engagement?

Most well-run onboardings produce clean board reporting within 30-60 days. Strategic impact - a fundable model, a clear plan, reliable unit economics reporting - typically takes 60-90 days. If a firm promises board-ready output in two weeks, ask specifically what they mean by that. Speed claims are worth pressure-testing before you sign.
