Case Study · SaaS Scale-Up

Series B SaaS company builds finance function through offshore + fractional CFO.

Composite case based on common patterns with venture-backed B2B SaaS companies, $8M–$25M ARR, post-Series B. Roughly 15 similar engagements in our book. Generalizes specific company details while preserving operational mechanics.

Situation

Post-Series B finance situation

B2B SaaS company, roughly $14M ARR after Series B, 75 employees, 3-year-old company. Pre-raise finance function: one contract bookkeeper (part-time), one QBO setup that had grown organically, revenue recognition done through a manual spreadsheet, board reporting produced by the CEO with help from the bookkeeper.

Post-Series B investor expectations made this setup untenable:

Monthly board packages with KPI commentary, not just P&L
Clean ASC 606 revenue recognition with deferred revenue schedule
Monthly close by day 5 with variance commentary
Quarterly budget-vs-actual with forecast updates
Investor reporting on schedule (quarterly, plus ad-hoc)
Clean books for next round of due diligence

Options considered

Three paths the company considered:

Hire a US VP Finance at $220k base. Rejected: overkill for current scale, 4–6 month search timeline unacceptable, founder didn't want to give the FTE slot to finance vs product.
US-based outsourced CFO firm. Got quotes at $12k–$18k/month for combined CFO + controller + bookkeeping. Within budget but expensive for early-stage cash management.
Offshore-led structure. Ultimately chosen. Combined offshore controller + fractional CFO + junior offshore bookkeeper.

Engagement structure

The finance team structure that was built

Offshore team

Offshore senior controller (full-time equivalent). Senior accountant with Big 4 SaaS experience, covered monthly close, ASC 606 revenue recognition, deferred revenue management, AP/AR ownership, monthly financial statement preparation. Cost: $5,200/month.
Offshore junior bookkeeper (part-time, 80 hrs/month). Transaction coding, basic reconciliation, vendor bill entry, expense report processing. Cost: $1,400/month.
Fractional CFO (20 hrs/month). Monthly board reporting, investor communication, cash management, strategic finance input, banker relationships. Senior offshore CFO with prior Fortune 500 and SaaS experience. Cost: $3,600/month.

Total offshore cost: $10,200/month ($122,400 annualized)

Comparable US-only option modeled: US controller $120k base loaded + fractional US CFO 20 hrs at $250 = $60k + US junior bookkeeper 80hrs at $45 = $43k = $223k loaded. Offshore alternative delivered roughly 45% cost reduction for equivalent scope.

CEO and VP of Operations supervision

CEO spent approximately 4 hours/month on finance (vs previous 20 hrs/month pre-engagement). VP Operations served as primary US point of contact with offshore controller, spending 3–5 hours/week on finance coordination.

18-month arc

Engagement arc across 18 months

Months 1–3: cleanup and foundation

Historical books cleanup (3 months of work prior to Series B needed restating)
Chart of accounts rebuild for better investor reporting
ASC 606 revenue recognition implementation with contract-level analysis
Deferred revenue schedule built out for all existing subscriptions
Monthly close process documented and automated where possible

Output: first clean month-end close delivered day-9 of month 3. Target was day-5; hit that by month 5.

Months 4–9: steady state operations

Monthly close by day 5 consistently
Monthly board package delivered day 10 with full KPI commentary
Quarterly budget-vs-actual on schedule for board meetings
First investor quarterly report produced on time without drama
Customer expansion and churn tracked in structured way

Months 10–15: growth adaptation

Company ARR grew from $14M to $22M; transaction volume roughly doubled
Offshore controller added capacity: scaled from 40 hrs/week to full-time dedicated
Junior offshore bookkeeper scaled from 80 hrs/month to 120 hrs/month
Fractional CFO hours remained at 20/month – strategic work didn't scale linearly with transaction volume
Process automation added (Ramp for expenses, Tipalti for international payments)

Months 16–18: Series C preparation

Data room built out through fractional CFO leadership, offshore controller execution
QoE-style preparation for due diligence
Board pre-alignment for Series C timing
Company closed Series C successfully; offshore team continued post-raise

Economics

Economic outcome across 18 months

Cost

Monthly offshore cost: $10,200 starting, scaled to $12,400 by month 15
Total 18-month offshore cost: approximately $200,000
Comparable US-only model: approximately $380,000
Cost avoidance: ~$180,000

Value delivered

Series C raise closed with due diligence process described by lead investor as "cleanest we've seen at this stage"
No material accounting issues discovered in due diligence (contrast with earlier rounds where clean-up added 6 weeks)
CEO time freed from finance: estimated 15 hrs/month recovered across 18 months = 270 hours back to product and sales
Board satisfaction: CFO-level board package quality enabled more strategic board conversations

What didn't happen

Company did not hire a full-time VP Finance or CFO during this period. Fractional CFO arrangement was adequate for Series C. Company eventually hired full-time CFO at roughly 2 years post-Series C, when scale ($45M+ ARR) warranted full-time strategic finance leadership.

What typically goes wrong

Common friction points in this engagement pattern

Founder/CEO wanting to skip onboarding investment. Founders under time pressure often want to hand off finance immediately. Engagements that skip month 1 onboarding predictably struggle in month 3–6. Resolution: set founder expectations explicitly at kickoff about the 20–40 hour month-1 investment.
ASC 606 complexity underestimated. SaaS companies with hybrid revenue (subscription + implementation + services) often have messier revenue recognition than founders realize. Resolution: budget extra controller time in months 1–3 specifically for ASC 606 work.
Board package format debates. Every board has different expectations; first few monthly packages often have multiple revision cycles. Resolution: invest in first month's package format explicitly; subsequent months are fast when format is settled.
Fractional CFO being pulled into operational work. When books are messy, CEO wants fractional CFO to "just fix it." This drains strategic capacity into operational work. Resolution: hold the scope line; use offshore controller to fix operational issues, keep CFO on strategic work.
