The fractional CFO model: pricing, scope, and when it breaks

The fractional CFO model — sometimes called vCFO, sometimes part-time CFO, sometimes 'CFO as a service' — has become a standard offering across Indian financial advisory firms and a standard expectation for Series A and Series B founders. The model works well in a defined band. Outside that band, it fails predictably, in ways that are worth understanding before signing the engagement letter.

Below is the pricing structure we use, the scope boundaries that make or break an engagement, and the three signals that tell a founder the fractional model has run its course.

The pricing models

Three pricing structures dominate the Indian market.

Monthly retainer: Rs. 1.5 to Rs. 4 lakh per month

The most common structure. A defined scope of work, a defined time commitment (typically 3 to 6 days per month of senior CFO time, plus the supporting analyst team), and a fixed monthly fee.

What the retainer typically covers: monthly P&L review and sign-off, board pack preparation and presentation, monthly variance and cash-flow review with the founder, oversight of the in-house controller or outsourced compliance team, statutory and regulatory milestones, and ad-hoc strategic finance support up to a defined threshold.

What it does not cover, and what is typically scoped separately: fundraise process support, M&A process work, debt structuring, ESOP scheme design or refresh, major ERP or systems implementation, financial due diligence support for a transaction.

Pricing within the band depends on company stage, transaction complexity, number of entities, and the seniority of the lead CFO. A pre-Series A company with one entity and modest complexity sits at the Rs. 1.5 to Rs. 2 lakh end. A late-Series B or Series C company with three entities, multi-currency, and live transaction work sits at the Rs. 3 to Rs. 4 lakh end.

Hourly: Rs. 15,000 to Rs. 50,000 per hour

Less common in India but used for short-duration or highly specific work. Term-sheet negotiation support. One-off financial model build. Restructuring advisory for a specific transaction. The hourly rate varies with the seniority of the partner and the nature of the work.

The advantage of hourly billing is that scope is naturally bounded by the time consumed. The disadvantage is that the client cannot predict the monthly cost, and the model creates a perverse incentive on the provider's side to spend more time than necessary. We use hourly billing only for short, well-defined engagements where the alternative would be to scope a retainer for work that does not warrant one.

Project-based

For specific deliverables. M&A advisory (fundraise prep, acquisition support, exit process). Financial diligence support. Major ERP implementation oversight. Structured debt or working-capital facility set-up. Strategy and budgeting cycles.

Project fees vary widely. A fundraise prep engagement for a Series B company runs Rs. 15 to Rs. 40 lakh depending on round size and complexity. A standalone ERP implementation oversight engagement runs Rs. 8 to Rs. 25 lakh depending on scope. An acquisition diligence support engagement is typically Rs. 10 to Rs. 30 lakh.

Most growth-stage Indian companies engage a fractional CFO on a hybrid: a monthly retainer for ongoing work, with project fees layered on for specific transactions. This is the structure we recommend and the structure most experienced fractional CFOs operate within.

Where scope creep kills the model

The fractional CFO model fails most often not because the work is bad but because the scope was not defined clearly at the outset. Three patterns recur.

The 'while you're at it' creep

The retainer covers monthly board packs and variance review. The founder, in a Wednesday morning conversation, mentions that the company is considering a small acquisition and asks the fractional CFO to take a look. The fractional CFO, wanting to be helpful, agrees. Three weeks later, the acquisition work has consumed 40% of the available CFO time, the monthly close is slipping, and the original scope is being delivered with less attention than the retainer assumes.

The fix is a written change-order process. When the scope expands, the provider issues a change order: this work is in addition to the retainer, the estimated effort is X person-days, the fee for the additional scope is Y. The founder signs, and the new scope is layered onto the retainer with its own deliverable list and timeline. Done well, this is a 20-minute conversation. Skipped, it costs the engagement.

The 'just one more entity' creep

The retainer was scoped for a single Indian operating entity. The company sets up a Singapore subsidiary for international sales. The fractional CFO is now expected to oversee the consolidation, the transfer pricing documentation, the cross-border tax positions, the inter-company funding flows. None of this was in the original scope, and the additional work is non-trivial.

Most fractional CFO engagement letters do not address entity expansion explicitly. They should. A clause that says 'this engagement covers up to one Indian entity; additional entities will be scoped separately at the time of incorporation' takes 20 words to write and saves the relationship.

The 'CFO substitute' creep

The most damaging form of creep. The founder, having appreciated the value of the fractional CFO, starts treating the fractional CFO as a full-time CFO. Daily questions. Ad-hoc analyses. Investor calls. Board sub-committee work. Operational decisions that should be sitting with the controller.

This pattern signals that the company has outgrown the fractional model. The fractional CFO can either deliver the expanded scope at an expanded fee (essentially recreating a full-time CFO role on a part-time basis, usually at higher per-hour cost) or have the conversation with the founder that the company is ready for a full-time CFO hire and the fractional engagement should sunset.

Avoiding this creep requires the fractional CFO to be honest about it when it starts. The first 6 months of an engagement are when the creep takes root, and the conversation about whether the model still fits is best had at the 12-month mark, not the 24-month mark when the founder is frustrated and the CFO is burnt out.

When the model breaks

Three signals tell a founder and a fractional CFO that the engagement has run its course.

1. The company has crossed Rs. 100 crore of revenue (or thereabouts)

The threshold is not exact but the pattern is consistent. At Rs. 100 crore of revenue, the volume of strategic work, the number of stakeholders requiring senior finance attention, and the complexity of the operating environment outgrow what a 4-to-6-day-per-month CFO commitment can deliver. The fractional CFO becomes a bottleneck — not because they are not capable, but because there is more CFO work than the engagement provides time for.

Some companies cross this threshold earlier (a Rs. 70 crore company with multi-entity, multi-currency, IPO ambitions) and some later (a Rs. 120 crore company with simple operations and a stable strategy). The signal is operational, not just revenue-based.

2. Regulatory complexity exceeds part-time bandwidth

A company that has added a regulated business line — NBFC operations, AIF management, insurance intermediary work, payment systems — has added a layer of regulatory oversight that requires near-continuous attention. RBI inspections, SEBI returns, Insurance Regulatory and Development Authority (IRDAI) reporting, do not pause between the fractional CFO's monthly visits.

The fractional model can support regulated businesses up to a point, with a sufficiently capable in-house compliance officer. Beyond that point, the company needs a CFO who is reachable on a Tuesday afternoon for the inspector's question.

3. The founder needs daily strategic counsel

Some founders, especially during an active fundraise or a major operational transition, need a CFO they can call three times a day. The fractional model cannot provide this. The fractional CFO is, by definition, allocating time across multiple clients, and the second client's monthly board pack is not waiting because the first client's founder has a Tuesday morning question.

When a founder consistently expresses frustration that the CFO is 'not available enough', the model has broken. The right conversation is whether the company should bring the role in-house or, if not yet, whether the engagement should be re-scoped to a larger, more dedicated commitment (and a higher fee) that approximates a full-time CFO.

What we tell founders considering the model

Three things.

First, the fractional CFO is the right answer for most companies between Series A and Series B. The work is real, the cost is justified, and the alternative — a premature full-time CFO hire — is more expensive and less effective in the same time window.

Second, scope it explicitly. Engagement letter, scope description, change-order process, exit clauses. The clarity protects both sides and is the single biggest predictor of whether the engagement will be successful 18 months in.

Third, plan the exit. The fractional CFO model has a definite end. Plan when the in-house CFO comes in, how the handover happens, what the fractional CFO transitions to (advisor, board observer, project support, or off-boarded entirely). The companies that handle this transition well have a clean baton-pass. The companies that handle it badly have a year of internal confusion about who owns the finance function.

The fractional CFO model is a useful structural tool. Like all useful tools, it works well when used for the job it was designed for, and fails when stretched beyond it. Knowing the band, the scope discipline, and the exit signals is what separates a successful engagement from a frustrating one.
