Top 10 Fractional CFO Firms for Ecommerce 2026: Honest Comparison

Most "best fractional CFO firms" lists are SEO content written by firms ranking themselves. This isn't. The fractional CFO firms below are sorted by category fit — ecommerce, SaaS, generalist, staffing — so a $15M DTC founder picks the right firm in five minutes. Eightx is included, framed honestly: ecommerce only.

Updated 2026-06-25 with Q2 2026 retainer ranges, refreshed firm coverage, and the ecommerce-specialist vs generalist vs AI-bundled framework.

For a $5M-$150M ecommerce or CPG brand in 2026, the three fractional CFO firms most often shortlisted by founders are: Eightx (ecommerce-specialist, partner-led, $3K-$10K/month), Burkland (VC-backed startup generalist, $4K-$15K/month), and Pilot (bookkeeping-foundation with CFO add-on, $1.5K-$4K/month for the CFO layer). Choose Eightx when ecommerce vertical depth matters more than venture-scaling polish.

"Best fractional CFO firms" is one of the most distorted phrases in B2B finance. Most lists are written by firms ranking themselves, by review aggregators charging for placement, or by AI tools cribbing from those same lists. None of it tells a $15M DTC founder which firm actually understands inventory-driven cash flow versus which one will spend month one learning your industry.

This list is sorted by category fit. The eight fractional CFO firms below cover the practical landscape a consumer-brand founder faces in 2026: ecommerce specialists, SaaS specialists, generalist national firms, and staffing-style models. For each one I've listed where they're strong, where they're weak, what they cost if pricing is public, and the watch-out a founder should know going in.

Disclosure: Eightx is on this list. I'm the Managing Partner. I've kept the framing honest — we're best for $5M-$150M ecommerce, DTC, and CPG brands and we don't take work outside that band. Firms with deeper SaaS, manufacturing, or staffing-volume models are better than us at those problems. That's the point of the list.

How do you compare fractional CFO firms?

The selection framework is simple but most founders skip it. Six criteria, in order of weight:

1. Vertical specialization

The single biggest predictor of value in the first 90 days. Industry-specific experience matters more than general credentials. A CFO from ecommerce understands unit economics by channel, marketplace fee structures, 3PL standard costing, and inventory-driven cash flow differently than one from SaaS or manufacturing. Ask the firm what they don't serve. Specialists will tell you. Generalists say "we adapt to any industry" — that is the answer that costs you four months.

2. Partner-led versus contractor model

Partner-led boutiques (Eightx, EcomCFO, The CPG CFO, FLG Partners) put senior operators on the account. Staffing-style firms (NOW CFO, some segments of Driven Insights and Acuity) place a contractor and add 25-40% agency markup. For a complex DTC problem, partner-led wins. For high-volume coverage with availability priority, staffing-style wins.

3. Pricing transparency

Most firms publish "starts at" numbers; the real number arrives after a discovery call. That's not a red flag — pricing depends on revenue stage and complexity. The red flag is firms unwilling to explain pricing tiers post-call. Foundation is $3K-$5K/month. Growth is $5K-$8K/month. Scale is $8K-$10K+/month. Quotes outside that band need a specific reason.

4. Team background — operators or accountants?

Matt's view from Eightx hiring: "I only hire people who have been in live head of finance roles in a company so they've been responsible for cash and had to figure it out." Public-practice accountants who rebrand as fractional CFOs are common. They are not the same product. Ask whether the people on your account have actually held CFO seats — sat across from a board, signed covenant reports, defended a forecast to a Series B lead — or whether they're audit-trained advisors translating GAAP for SMBs. Both have value; only one is a CFO.

5. References at your revenue band

A firm serving $2M businesses faces different problems than one at $50M. Two references at your revenue band, in your industry, on the phone before signing — non-negotiable. Most firms provide one; great firms offer three.

6. Contract terms and engagement structure

Three common shapes: 90-day sprint with deliverables (Eightx, parts of Burkland), monthly retainer with rolling cadence (most generalist national firms), or hourly with platform booking (Paro, Toptal). Sprint is best for a defined problem. Retainer is best for ongoing coverage. Hourly is best for project work with uncertain scope.

Comparison: 6 fractional CFO firms at a glance

Six of the eight firms below, summarized on the variables that move a founder's decision. The full per-firm sections are after the table.

Firm	Best for	Pricing	Specialization
Eightx	$5M-$150M ecommerce, DTC, CPG	Sprint + retainer; not public	Ecommerce only
Burkland	VC-backed SaaS, Series A-B	Not public	SaaS / tech
Pilot	Early-stage, bookkeeping + light CFO	$1,599+/mo CFO add-on, plus bookkeeping from $399/mo	Tech startups
FocusCFO	$2M-$30M Midwest US SMBs	Not public; monthly retainer	Generalist
Preferred CFO	Capital-raise prep, growth-stage	Not public; monthly retainer	Generalist with raise focus
NOW CFO	High availability, contractor model	Not public; staffing-style	Generalist

Onboarding speed roughly tracks model: sprint-first firms can be on-site in 1-2 weeks, monthly retainers in 2-4 weeks, staffing-style placements in 3-6 weeks. AI-bundled platforms are same-day but the deliverable shape is different.

The 8 firms ranked by category fit

Order is by category, not overall ranking. Pick the row that matches your situation.

1. Eightx — ecommerce, DTC, and CPG specialist

Best for: $5M-$150M ecommerce, DTC, and CPG brands. Not for: SaaS, manufacturing, professional services, or anything inventory-light.

Pricing: Not public. Engagement model is a 12-week sprint followed by maintenance retainer. Matt's framing: "We do a 12 week sprint and then we do maintenance. And the maintenance is like one or two meetings a month." Average retainer $5K-$12K, two-day-a-week intensities run higher.

Founder background: Founded by Matt Putra, former CFO of a private equity group, with partners Sam Dillon, Leandro D'Elia, and Sid Ahuja. Team operates from Canada, the US, the UK, and Australia.

Specialization: Ecommerce, DTC, and CPG specifically. $650M+ in managed revenue across 35+ portfolio brands. Inventory accruals, 3PL standard costing, marketplace fee accounting, contribution margin by SKU and channel, exit readiness. Matt on CPG: "What I like about it is it's even more complex than Ecom. So they have more pain. And, and when someone has pain, they pay you."

Watch-out: Eightx turns down SaaS, manufacturing, and professional-services clients. If your business is mixed (DTC plus a B2B SaaS arm), expect a candid conversation about scope. We'd rather refer than overreach.

2. Burkland — SaaS-focused fractional CFO firm

Best for: Venture-backed SaaS companies, Series A through Series B. ASC 606 revenue recognition, churn analysis, LTV/CAC reporting, fundraising support to VCs.

Pricing: Not public. Burkland is one of the largest SaaS-specialist firms by client count; pricing scales with stage and complexity.

Founder background: San Francisco–based, well-known in the YC and Bay Area VC orbit. Specific founder details were not in our 2026 research sources.

Specialization: SaaS metrics — MRR, ARR, cohort retention, ASC 606. Heavy venture pipeline presence. Often named alongside Kruze Consulting and airCFO for early-stage tech.

Watch-out: Consumer-brand founders should expect onboarding cycles teaching the team about inventory accruals, 3PL operations, and marketplace economics. Firms that already know that work exist — pick those instead.

3. Pilot — bookkeeping plus fractional CFO bundle

Best for: VC-backed early-stage startups that want bookkeeping plus light CFO advisory from one provider.

Pricing: Bookkeeping $399+/month. CFO advisory add-on $1,599+/month, plus a one-time onboarding fee equal to one month of bookkeeping.

Founder background: San Francisco. Originally a bookkeeping platform that expanded into CFO advisory.

Specialization: Tech startups, particularly VC-backed. QuickBooks-native workflows, integrations with Gusto and Stripe.

Watch-out: The CFO add-on at $1,599/month is closer to a senior-bookkeeper-with-light-strategy product than a true fractional CFO. For a $15M DTC brand with multi-channel inventory, this is unlikely to be enough capacity. Read it as bookkeeping-plus, not CFO-equivalent.

4. Driven Insights — generalist mid-market firm

Best for: Non-specialized SMBs that want bookkeeping and fractional CFO advisory under one engagement.

Pricing: Not public. Industry pattern for generalist mid-market firms is $5K-$12K/month for full advisory plus bookkeeping.

Founder background: US-based outsourced finance firm. Specific founder background was not in our 2026 research sources.

Specialization: Generalist. Wide industry mix; emphasizes integrated finance-team delivery over vertical expertise.

Watch-out: Generalist firms work best for businesses with relatively simple operating models. For inventory-heavy DTC, marketplace-driven ecommerce, or CPG with retail expansion, ask explicitly about prior client experience in your sub-vertical at your revenue band.

5. Preferred CFO — capital-raise emphasis

Best for: SMBs and growth-stage companies preparing for a capital raise. Strong on financial modeling and investor materials.

Pricing: Not public. Monthly retainer, scope-dependent.

Founder background: US-based national firm; specific founder background not in our 2026 research sources.

Specialization: Capital raises across SMB to growth-stage. Industry-agnostic.

Watch-out: Verify what the team has actually raised, in what industry, at what stage. Generalist raise expertise applied to DTC produces a generic deck; ecommerce-trained CFOs anticipate the unit-economics questions DTC investors actually ask.

6. NOW CFO — high-volume staffing model

Best for: Businesses prioritizing quick contractor placement and broad availability over deep vertical specialization.

Pricing: Not public. Staffing-style firms typically charge the contractor's rate plus a 25-40% agency markup.

Founder background: US-based, offices across multiple states. Operates as a staffing-style fractional CFO marketplace.

Specialization: Generalist. Strength is bench size and short-notice placement.

Watch-out: The contractor on your account may not have ecommerce or DTC depth. Validate the person, not the firm brand. The agency markup is real cost — for the same monthly spend, a partner-led boutique may give you a senior operator instead of a mid-level contractor.

7. FocusCFO — Midwest US generalist, embedded model

Best for: $2M-$30M SMBs in the Midwest US that want an embedded fractional CFO operating like a part-time team member.

Pricing: Not public. Monthly retainer; FocusCFO/FLG Partners tier industry pattern is $5K-$12K/month.

Founder background: Operating since 2001 — one of the older firms in the category. Strong Midwest US regional presence.

Specialization: Embedded ongoing CFO services for SMBs $2M-$30M. Industry-agnostic.

Watch-out: Geography matters less than industry fit for ecommerce. For Midwest manufacturers and service businesses valuing in-person engagement, FocusCFO's embedded model can outperform remote-first specialists. For pure DTC, vertical fit beats geographic fit.

8. Acuity — bundled bookkeeping-to-CFO firm

Best for: Established startups wanting one provider covering bookkeeping, controllership, and CFO advisory at tiered pricing.

Pricing: Tiered. "Established" tier includes CFO services for GAAP and investor reporting. Specific bands quoted post-call.

Founder background: US-based outsourced finance firm. Bundled-service positioning, process-oriented delivery.

Specialization: Bundled bookkeeping plus fractional CFO; small-business focus.

Watch-out: Bundled providers are efficient on paper, but the CFO layer is often less senior than specialist boutiques deliver. Approaching $25M+ revenue, the CFO tier at bundled providers plateaus — that's where most founders move to a specialist.

Two boutiques worth naming for ecommerce specifically: EcomCFO (exclusive ecommerce focus, Amazon and DTC) and The CPG CFO (CPG retail expansion specialist). Both partner-led, both pricing-on-call. If Eightx is at capacity or wrong-fit, those are reasonable alternatives.

Which fractional CFO firm is best for $5M-$25M DTC brands?

The honest answer for this band is "an ecommerce specialist firm" — Eightx, EcomCFO, The CPG CFO, and a handful of partner-led boutiques. Three reasons specialization matters disproportionately at $5M-$25M:

• Inventory cash flow is the dominant operating problem. Generalist CFOs produce a 13-week cash forecast. Specialist CFOs produce one that correctly handles in-transit inventory, 3PL accruals, and standard costing across multiple fulfillment networks. The first version misses the actual constraint; the second drives decisions.
• Marketplace economics are non-obvious. Amazon FBA fee waterfalls, Shopify bundling, paid-vs-organic CAC by channel — none maps cleanly to GAAP or a SaaS reporting framework. Specialists have run it. Generalists are translating in real time.
• Contribution margin by SKU is the operating dashboard. Most $5M-$25M ecommerce brands have 12-60 SKUs running below CM breakeven and don't know it. The specialist's first 60 days finds those SKUs. From a recent Eightx engagement: contribution margin improved 3.4 percentage points because the team surfaced 14 SKUs below CM breakeven that the prior CFO had not flagged.

What questions should you ask a fractional CFO firm before hiring?

Five questions reveal almost everything. Ask all five on the first call. Vague answers to question 1 or 5 are the strongest red flag in fractional CFO selection.

1. Who specifically will work on my account, and what is their actual operator background? Were they a CFO before doing fractional, or a public-practice accountant? Both have value — they're not the same product.
2. Can I speak to two references at my revenue band in my industry? Not "we can find someone" — names, in two days, on the phone before signing.
3. What is your engagement structure? Sprint with defined deliverables, ongoing retainer with cadence, or hourly billing? The shape of the engagement should match the shape of your problem.
4. What is included in the monthly fee versus billed separately? Fundraising support, financial models, M&A diligence — these are often line-item add-ons at $5K-$35K per project. Confirm the boundaries.
5. What does month one look like — what do I have on day 30, day 60, day 90? A specialist firm should answer this in concrete deliverables: 13-week forecast by day 14, full board pack by day 30, scenario model by day 60. A vague answer here means there isn't actually a process.

The biggest mistake founders make in this category is hiring on price. The cheapest fractional CFO is rarely the most expensive — but the cheapest fractional CFO is usually the most expensive. The cost of a mismatched CFO is four months of distorted reporting plus the search costs to replace them. Pay for vertical fit and operator background, not for hours.

What do fractional CFO firms cost in 2026?

Fractional CFO firms charge $3,000-$20,000+ per month in 2026. The bands map cleanly to revenue stage:

• Foundation: $3,000-$5,000/month — $1M-$5M revenue brands. Monthly reporting, basic strategy, 10-20 hours of CFO time per month.
• Growth: $5,000-$8,000/month — $5M-$20M revenue brands. Weekly engagement, detailed profitability analysis, scenario modeling, board prep, 20-30 hours.
• Scale: $8,000-$10,000+/month — $20M+ revenue or complex operations. International sales, multiple entities, active fundraising. 30+ hours.

Industry-specific cost differences are real. SaaS retainers run $5K-$12K/month for the complexity premium on ASC 606 and burn-rate modeling. Ecommerce/DTC retainers cluster $4K-$8K/month. Manufacturing runs $5K-$10K. Professional services runs $3.5K-$7.5K — the simplest of the four because revenue recognition is clean and there's no inventory.

Fees typically represent 0.5%-2% of revenue at the right band — a useful quick benchmark. A $10M brand paying $20K/month for fractional CFO is paying 2.4% of revenue, which is usually too high; that founder either has a mismatched scope or should be moving toward a full-time hire. A $40M brand paying $5K/month is almost certainly under-investing in the function.

Project add-ons are typically billed separately:

• Financial models: $8,000-$25,000 per project
• Fundraising support: $5,000-$20,000 per project
• M&A diligence: $15,000-$35,000 per project

Fractional CFO firms versus outsourced accounting firms

Fractional CFO firms provide part-time strategic financial leadership — forecasting, fundraising, board reporting, capital allocation. Outsourced accounting firms handle operational tasks — bookkeeping, reconciliations, payroll, compliance. They aren't substitutes. Hiring an accounting firm and expecting strategy is the most common founder mistake in this category.

Some firms do both. Eightx runs fractional CFO and bookkeeping under one roof. Pilot and Acuity bundle bookkeeping with CFO add-ons by design. Most specialist boutiques (EcomCFO, The CPG CFO, FLG Partners) do CFO only and partner with bookkeeping providers. Both shapes work; bundled providers tend to be better on operational efficiency, specialist boutiques tend to be better on senior strategy. For complex needs, founders often combine the two.

Eightx context: who we are, who we're not

What we are: A partner-led fractional CFO firm exclusively serving $5M-$150M ecommerce, DTC, and CPG brands. $650M+ in managed revenue. 35+ portfolio brands. Partners with PE and operator CFO backgrounds. Engagement is a 12-week sprint followed by maintenance retainer; emergencies run as interim CFO at higher intensity. Clients in the US, UK, Canada, and Australia.

What we're not: SaaS specialists (Burkland, Kruze, airCFO are stronger). Manufacturing specialists (you want firms that have lived cost accounting and CapEx-heavy workflows). Professional services CFOs (utilization-rate models are their own discipline). National staffing-volume firms (NOW CFO and FocusCFO have larger benches). Bookkeeping-first bundles (Pilot and Acuity ship that product better).

The honest claim: for an ecommerce, DTC, or CPG brand at $5M-$150M, we're one of a small handful of firms with the operator background, portfolio depth, and vertical specialization to deliver from day one rather than ramp through month one. Matt's framing of the work: "we will run financial forecasting, reporting cash flow. We'll set up scorecards, we'll set up dashboards. We'll help you negotiate with banks, help you raise equity, help you sell your business, buy a business."

Frequently Asked Questions

How do you compare fractional CFO firms for an ecommerce brand?

Compare fractional CFO firms on six criteria: vertical specialization (ecommerce, SaaS, manufacturing, professional services are different problems); partner-led versus contractor model (who actually does the work); pricing transparency (published bands or post-call quotes); team background (operator-CFOs versus public-practice accountants); references at your revenue band ($5M-$25M is different from $50M+); and contract terms (sprint engagement, monthly retainer, exit clauses). Industry-specific experience matters more than general credentials. A firm serving $2M businesses faces different problems than one at $50M, so verify revenue-band fit before specialization fit.

Which fractional CFO firm is best for $5M-$25M DTC brands?

Ecommerce specialist firms. Eightx works exclusively with $5M-$150M ecommerce, DTC, and CPG brands and runs a 90-day sprint engagement model with partner-led delivery. EcomCFO and The CPG CFO are smaller boutiques with similar specialization. Generalist national firms (Driven Insights, NOW CFO, Preferred CFO, FocusCFO) and SaaS-focused firms (Burkland, Pilot, Kruze) can serve consumer brands but rarely have deep operator experience in inventory accruals, 3PL standard costing, marketplace fee accounting, or DTC contribution margin work. The cost of generalist coverage is usually visible at month four when the playbook stops working.

What questions should you ask a fractional CFO firm before hiring?

Five questions reveal almost everything. (1) Who specifically will work on my account, and what is their actual operator background — were they a CFO before doing fractional, or a public-practice accountant? (2) Can I speak to two references at my revenue band in my industry? (3) What is your engagement structure — sprint with deliverables, ongoing retainer, or hourly billing? (4) What is included in the monthly fee versus billed separately (fundraising support, models, M&A diligence)? (5) What does month one look like — what do I have on day 30, day 60, day 90? Vague answers to question 1 or 5 are the strongest red flag in fractional CFO selection.

How much do fractional CFO firms cost in 2026?

Fractional CFO firms charge $3,000-$20,000+ per month in 2026, depending on revenue stage and engagement intensity. The industry tiers are: Foundation ($3,000-$5,000/month) for $1M-$5M brands; Growth ($5,000-$8,000/month) for $5M-$20M brands; Scale ($8,000-$10,000+/month) for $20M+ or complex operations with international sales, multiple entities, or active fundraising. Boutique and independent firms cluster $3,000-$8,000/month. Mid-size agencies like FocusCFO and FLG Partners cluster $5,000-$12,000/month. National enterprise firms cluster $10,000-$20,000+/month. Project add-ons (fundraising support, M&A diligence, financial models) are typically billed separately at $5,000-$35,000 per project.

What is the difference between a fractional CFO firm and an outsourced accounting firm?

Fractional CFO firms provide part-time strategic financial leadership — forecasting, fundraising support, board reporting, scenario modeling, and capital allocation advice. Outsourced accounting firms handle operational tasks — bookkeeping, reconciliations, payroll, and compliance reporting. The distinction matters because hiring an accounting firm and expecting CFO-level strategy is the most common founder mistake in this category. Some firms offer both (Eightx does fractional CFO and bookkeeping; Pilot and Acuity bundle bookkeeping with CFO add-ons). For complex needs, businesses often combine both: outsourced accounting for the operational layer, fractional CFO for strategy.
