How to Choose a Fractional CFO: A 7-Question Framework for $5M-$50M Brands

How to choose a fractional CFO at a $5M-$50M ecommerce or DTC brand: run every candidate through a 7-question framework covering revenue-band fit, partner-vs-junior staffing, retainer scope, references, engagement structure, scope-creep handling, and exit terms. Score each answer. A 5-out-of-7 score is a fit. A vague answer on any one question is a red flag.

You are scaling a $5M-$50M ecommerce, DTC, or CPG brand. Cash is tight despite growth. Marketing efficiency is slipping. Inventory turns feel off. You know you need senior strategic finance, but a full-time CFO at $250K all-in is overkill. Fractional CFO is the answer. So you Google "fractional CFO," get 200 firms, half of them ex-bookkeepers calling themselves CFOs, the other half want $30K/month and will not tell you what they actually do.

This is the framework I use when founders ask me how to evaluate my firm or anyone else's. I run a fractional CFO firm with $650M+ in client revenue under management across 35+ ecommerce, DTC, and CPG brands. Every partner on our team has been a live head-of-finance, actually responsible for cash, inventory, and the next round, before joining the firm. The 7 questions below are the ones that consistently separate the firms that will move your business forward from the ones that will charge you for monthly spreadsheets.

So there's a range of types of fractional CFO. You have the somebody that was a public practice accountant that's just calling themselves a fractional CFO. We aren't that type. I only hire people who have been in like live head of finance roles in a company so they've been responsible for cash and had to figure it out., Matt Putra

The 7 questions every founder should ask

Use these in your first 30-minute discovery call with any fractional CFO firm. Take notes. Score each answer 0 or 1 (clear and specific = 1, vague or hand-waved = 0). At the end, total the score. Anything below 5 is a pass.

1. What revenue band do you specialize in?

The right answer is a tight range, not "we work with everyone." A fractional CFO who has spent the last decade between $5M-$150M ecommerce brands knows things a Big-4-trained CFO does not, how marketplace settlements work, how inventory days kill cash, why contribution margin matters more than gross margin, and how to negotiate a 60-day vendor term when your cash conversion cycle is 90 days.

Watch for: "we serve startups to enterprise" or "any size from seed to growth stage." That means they will be learning your business model on your dollar. The right firm names a revenue band, names the verticals they live in, and names the ones they do not. At Eightx we run brands from $5M to $150M in ecommerce, DTC, and CPG. No SaaS, no professional services. If a SaaS founder calls us, we tell them to call Burkland.

2. Are you a senior partner or a junior contractor?

This question separates real fractional CFO firms from staffing-mill arbitrage. The pattern: a senior partner with 20 years of experience pitches the engagement, the founder signs, and a junior contractor or ex-bookkeeper executes the work. The founder pays senior pricing for controller-quality output. Industry research is consistent, bait-and-switch staffing is the most-cited red flag across CFO Advisors, Mercury, and InflectionCFO.

I only hire industry people, so I don't hire accountants from an accounting firm to be CFOs. I don't think that's fair. So one of my guys was a CFO for a billion dollar hotel chain. The other was a CFO for a hundred million dollar mine. Another guy was CFO for a 10-company ecom group in Australia., Matt Putra

Ask directly: "If we sign, who specifically is doing the work?" The right firm names the partner, the senior analyst, and the junior analyst, and the partner is on every call. At Eightx, every client gets a partner-level CFO (Matt Putra, Sam Dillon, Leandro D'Elia, or Sid Ahuja), a senior analyst, and a junior analyst. The partner runs strategy. The analysts execute the model, scorecards, and cash forecast. We staff this way because the work is faster and less costly than a partner doing everything alone.

3. What's included at your monthly retainer (and what's extra)?

This is where most fractional CFO engagements quietly go off the rails. The retainer covers the basics. Fundraising support is extra. Audit prep is extra. Board pack is extra. Then the founder gets a $14K invoice in month 4 and trust evaporates.

Ask for the deliverable schedule in writing before you sign. The right answer covers, at minimum:

• Monthly financial reporting package (10-15 pages with notes on what it means for the business)
• Rolling cash forecast (typically 13-week, refreshed weekly or biweekly)
• Three-scenario financial model (base, best, worst case)
• Department scorecards (marketing, ops, finance)
• Weekly or biweekly leadership cadence
• Board pack support if you have a board
• One named senior partner accessible by Slack or email between meetings

What is reasonable to charge as a project: a fundraising round (Series A or B-prep typically $8K-$25K), a major M&A diligence package, a tax audit response, an ERP migration. Industry benchmarks from Madras Accountancy's 2026 rate guide put ecommerce/DTC monthly retainers at $4,000-$8,000 for 15-25 hours/week, with project-based work billed separately.

What we're trying to do is that we know where we're going, we know how to get there, we know where we are on the path always. And even if it's bad news, as long as you know where you are, you can fix it usually or do something about it., Matt Putra

4. Can I see 3 client references at my revenue stage?

The easiest question to ask and the most often skipped. A real firm gives you three names within 24 hours, at your revenue stage, in your vertical, and ideally in a similar growth phase.

What to ask the references:

• Was the senior partner who pitched the engagement actually doing the work?
• How fast did the firm turn around model updates when something changed?
• What was the most valuable thing the CFO did in your first 90 days?
• Was anything in the relationship surprising, invoicing, scope, communication?
• If you had to choose again knowing what you know now, would you?

If a firm cannot produce three references at your stage, they are either too new, too small, or hiding something. Industry research from SaunLimited backs this, references from similar-stage clients are the single best predictor of fit.

5. What's your engagement structure (90-day sprint? rolling?)

Structure tells you how the firm thinks about value. Two patterns dominate:

• Open-ended monthly retainer. You pay a flat fee, the firm shows up, work happens, theoretically forever. Risk: low intensity, scope creep on both sides, no clear milestones.
• Sprint-then-maintenance. A defined 90-day onboarding sprint with explicit deliverables, then lower-touch monthly maintenance.

At Eightx we use sprint-then-maintenance. The first 90 days are an audit, financial model, scorecards, cash forecast, and marketing plan rebuild. Then monthly check-ins, reforecasting, and reporting. The sprint forces clarity for us and the founder on what value the engagement is producing. By day 30 you have the audit, day 60 the model, day 90 a working operating system. If we have not produced that, fire us.

So we as the CFO thing, 8 to 12 week sprint. Then we're going to do monthly check-ins and maintenance and reporting, make sure we're on track., Matt Putra

6. How do you handle scope creep?

Every fractional CFO engagement has scope creep. The question is how the firm handles it. Three patterns:

• Bill more silently. Retainer was 20 hours/month, you used 35, firm sends an invoice for the overage in month 4. Trust evaporates.
• Refuse the work. Retainer is the retainer. New scope means new contract. Slow but predictable.
• Change-order in writing. New scope (fundraising, M&A diligence, emergency tax) gets a written change order before any work. You approve or decline.

The third is the only acceptable pattern. Demand a deliverable schedule and a change-order clause before signing.

7. What's your exit clause?

Engagements end. Sometimes you outgrow the firm, sometimes you hire a full-time CFO, sometimes the chemistry is wrong, sometimes the firm is the wrong fit and you find out in month 3. The exit clause matters. A different case worth flagging: if your CFO just left and you need someone in the seat full-time for a few months, an interim CFO engagement is a cleaner fit than a rolling fractional retainer.

Acceptable terms:

• 30-day notice for either side, no penalties
• 60-90 day notice for either side, with a documented handover clause (the firm produces transition docs, briefs the next CFO, transfers all working files)
• Clear IP ownership, the financial model, scorecards, and forecasts you paid for belong to you when the engagement ends

Unacceptable terms: 12-month minimum lock-ins with no out clause, vague IP language that says "tools and methodologies" remain firm property (which can include your model), or rigid firm-only-controls-the-relationship structures that prevent you from hiring the partner directly if you want to.

Red flags vs green flags

The two-column shorthand for everything above. Use it as a final check before signing.

Red flag	Green flag
"We work with everyone, startup to enterprise"	Names a tight revenue band ($5M-$150M, $1M-$10M, etc.) and a vertical focus
Senior partner pitches; junior contractor executes	Partner is on every call; team named in the contract
Background is public-practice accounting only	Senior team has lived in head-of-finance / CFO roles before
Hourly billing, no cap, no scope	Monthly retainer with deliverable schedule in writing
"We'll figure out scope as we go"	Day-30, day-60, day-90 deliverables defined upfront
Refuses to give 3 references at your stage	Three named references within 24 hours
12-month minimum lock-in, vague IP terms	30-90 day notice clause, client owns deliverables
Static monthly spreadsheet only	Real-time KPI dashboards, weekly cash refresh
Generic board decks not investor-ready	Investor-grade reporting, scenario modeling, customized board packs
Vague answer on what the first 30 days look like	Specific 90-day sprint with audit + model + scorecards as named outputs

The decision scorecard

Score each candidate firm out of 7 across the framework above. Tally up. Then check for absolute disqualifiers separately.

5 or more = the firm is a fit. Move to a paid pilot or a 90-day engagement.

3-4 = caution. Re-interview specifically on the missing answers; if they cannot tighten up, pass.

0-2 = pass. Continue your search. Most firms in this band will burn you on scope or staffing.

Disqualifiers regardless of score: any firm where the work is delegated to public-practice accountants without operating experience, any firm where pricing depends on hours-not-yet-known, any firm where references cannot be produced.

How does Eightx compare to other firm models?

The fractional CFO market splits into four buckets:

• Solo ex-CFOs. Deep expertise, founder-level fit. Capacity constraints, vacation gaps, no analyst leverage.
• Big-firm services (KPMG, Deloitte tier). Brand credibility, audit-ready output. Expensive, partners-pitch-juniors-execute, weak vertical fit for $5M-$50M ecommerce.
• Staffing-agency contractors. Fast to start. Variable quality, 25-40% agency markup, no firm-level QA.
• Boutique vertical-focused firms (where Eightx sits). Senior-partner-led, vertical-deep, team-based, predictable retainer. Limited verticals, we do not do SaaS, professional services, or pre-revenue.

Honest framing: if you are SaaS, hire Burkland. If you are $250M+ enterprise, hire full-time. If you are $5M-$150M ecommerce, DTC, or CPG, a boutique vertical firm, us or one of 4-5 firms in our space, is the right call. More detail in our 2026 pricing guide and what a fractional CFO actually does for ecommerce.

Today a fractional arrangement can get you from, call it $5M, all the way up to $100M-plus. I have one company we worked with at $100M for almost two years. I don't see them hiring full-time for maybe another year., Matt Putra

What does a strong fractional CFO actually deliver in the first 90 days?

If a candidate cannot tell you what ships by day 30, day 60, and day 90, they will not deliver consistently after they sign. What good looks like:

• Day 1-30: Audit. Full review of chart of accounts, books, close cadence, existing reporting, cash position, AP/AR aging, inventory. Output: written audit covering what is good, what is broken, what to fix first.
• Day 30-60: Financial model. Three-scenario model (base, best, worst). Marketing plan, hiring plan, inventory plan, cash forecast all flow from the model. Department scorecards built off it.
• Day 60-90: Operating system. Weekly leadership meeting agenda, monthly reporting package, board pack template, scorecard cadence. Founder and team know what to do every week.

If at day 90 you do not have an audit, a model, scorecards, and a working cadence, the firm under-delivered. Fire them or renegotiate.

How do I know if I need a fractional CFO instead of a controller or bookkeeper?

This is the most common question we get on the first sales call. The short answer: bookkeepers handle history, controllers handle reporting and compliance, fractional CFOs handle decisions. They do different jobs. Most $10M-plus brands need all three.

Revenue	What you need	Why
<$5M	Bookkeeper	Daily transactions, reconciliations, basic P&L. No strategic decisions yet at scale that justify CFO cost.
$5M-$10M	Bookkeeper + Controller (often fractional)	Multiple revenue streams emerge. Errors get expensive. Controllers handle month-end close and compliance.
$5M-$50M	Bookkeeper + Controller + Fractional CFO	Cash decisions, channel mix, inventory turns, fundraising. Forward-looking strategic work the controller does not own.
$50M-$150M	In-house finance team + Fractional CFO (or ramp to full-time)	Some brands stay fractional through $100M+. Others bring full-time CFO once team passes 100-150 people across 8-10 departments.

The difference between the controller and the CFO is the controller is today and historical. They're going to help you understand what happened. CFOs are going, okay, what does that mean about the past? And how does that apply to the future?, Matt Putra

What does the engagement look like at Eightx specifically?

Concrete answer for founders who have read this far:

• Team: One named senior partner (Matt Putra, Sam Dillon, Leandro D'Elia, or Sid Ahuja), one senior analyst, one junior analyst. Partner is on every call.
• Sprint: 90-day onboarding, audit, model, scorecards, cash forecast, marketing plan refresh. Deliverables defined at day 30, 60, 90.
• Maintenance: Monthly reporting package, biweekly cash refresh, weekly or biweekly leadership cadence. Slack and email between meetings.
• Pricing: Monthly retainer based on revenue band and complexity. No hourly billing. Project work priced separately and only when scoped.
• Length: Most clients run 12-36 months. ~40% extend past 12 months.
• Verticals: Ecommerce, DTC, CPG. $5M-$150M revenue. Inventory-heavy businesses. No SaaS, no professional services, no pre-revenue.
• Geography: Clients across the US, UK, Canada, and Australia.

Track record: $650M+ in client revenue under management across 35+ active brands. Partners include former PE investors, former $100M-revenue heads of finance, former $1B hotel-chain CFO, and former 10-company ecom group CFO in Australia.

Frequently Asked Questions

How do I choose a fractional CFO for a $5M-$50M ecommerce brand?

Run candidates through 7 questions: (1) what revenue band do they specialize in, (2) is the work senior-partner-led or junior-contractor-executed, (3) what is included at the monthly retainer and what costs extra, (4) can they share 3 client references at your revenue stage, (5) what is the engagement structure (90-day sprint, rolling, project-based), (6) how do they handle scope creep, and (7) what is the exit clause. A firm that answers all 7 cleanly with specifics is a fit. A firm that gets vague on any of them is a red flag. For ecommerce, DTC, and CPG brands $5M-$150M, also screen for vertical fit, SaaS-trained CFOs do not understand inventory cash conversion or marketplace settlement reconciliation.

What is the biggest red flag when hiring a fractional CFO?

Bait-and-switch staffing: a senior partner pitches the engagement, then a junior contractor or ex-bookkeeper executes it. The whole reason to hire fractional is to get senior strategic input you could not afford full-time. If the actual day-to-day work is delegated to someone with a public-practice accounting background and no live head-of-finance experience, you are paying senior pricing for a controller-quality output. Ask in the sales call: who specifically is doing the work, and what are their last three operating roles.

How much does a fractional CFO cost in 2026?

For ecommerce and DTC brands $5M-$50M, expect $4,000-$12,000/month for a 15-25 hour/week engagement. SaaS and tech brands trend higher ($5,000-$12,000/month for 20-35 hours). Pricing structures include monthly retainer (most common, $10K-$30K depending on tier), project-based (fundraising support, audits, $8K-$25K per scope), or hourly ($150-$450/hour, rarely used because of scope creep risk). At Eightx we run a fixed-scope monthly retainer with a 90-day onboarding sprint built in, we tell you upfront what is included and what is not.

How long does a fractional CFO engagement typically last?

At Eightx, engagements start with a 90-day sprint (audit, financial model, scorecards, cash forecast), then transition to monthly maintenance and reporting. About 40% of engagements extend past 12 months as the brand scales. We have one client at $100M+ revenue we have worked with for almost 2 years and do not see them needing a full-time CFO for at least another year. The fractional arrangement can carry most ecommerce brands from $5M up to $100M-plus before the operational complexity demands a full-time hire.

When should an ecommerce brand hire a fractional CFO vs a controller vs a bookkeeper?

Bookkeeper for sub-$5M with simple operations, daily transaction recording, reconciliations, basic P&L. Controller for $5M-$10M with multiple revenue streams or expanding inventory complexity, historical reporting, month-end close, compliance. Fractional CFO once revenue exceeds $5M-$10M and the founder is making strategic decisions on cash, inventory, channel mix, pricing, or fundraising. The CFO is forward-looking, what does the past mean for the future. The controller is backward-looking, what happened in the past. They are different jobs. Most $10M-plus ecommerce brands need both: a bookkeeper or controller handling history, a fractional CFO handling decisions.
