Fractional CFO for communication & collaboration software companies
Communication and collaboration software typically combines per-seat SaaS with usage - minutes, messages, storage, increasingly AI tokens. Self-serve and enterprise motions run alongside each other, and the unit economics differ enough that averaging across the customer base produces metrics that mean nothing.
Self-serve and sales-led cohorts report as separate businesses inside the business, with their own CAC, payback and gross margin. Infrastructure costs - bandwidth, telecom termination, AI inference - get modelled at workload level so the cost of heavy free-tier usage stays visible.
Flow provides financial modelling, FP&A and fractional CFO advisory to communication and collaboration software companies across team messaging and conferencing, voice and video infrastructure (CPaaS, UCaaS, CCaaS), email and customer communication, async collaboration, and community and creator collaboration. We work as the outsourced startup CFO through growth, fundraising and sale processes.

Financial modelling for "communication & collaboration software" startups
As fractional CFOs, we build KPI-driven financial models that are insightful and easy to maintain.
Financial modelling is both art and science - models must be robust, but also understandable, and useful for both internal planning and VC fundraising purposes. Hire a fractional CFO who knows how to handle both sides of the equation.
Self-serve vs sales-led P&L
Two cohorts run as separate businesses inside the model - own CAC, own payback, own gross margin. Averaging across them produces metrics that flatter one motion and indict the other without anyone seeing it.
Workload COGS - bandwidth, telco, AI
Bandwidth, telecom termination and AI inference attributed to specific customers and product surfaces. The cost of supporting heavy free-tier and consumption usage stays visible rather than absorbed into a single COGS line.
Free-to-paid conversion funnel
Cohort-level conversion from sign-up to paid team to enterprise tracked over twelve to twenty-four months. Shows where the funnel is leaking and whether free-tier infrastructure spend is converting at rates that justify it.
Seat ARR & consumption waterfall
Bookings to billings to revenue split between seat ARR and consumption - minutes, messages, tokens - with overages and true-ups modelled by usage cohort. Removes the optical lift consumption can give an otherwise flat seat business.
NDR by segment and motion
Net retention measured separately for self-serve and sales-led books, with seat expansion and consumption upsell decomposed. The two engines compound differently and a single NDR number hides which one is doing the work.
Sales capacity model
Field quota, AE ramp and CS coverage tied to enterprise seat and consumption targets, with self-serve modelled off marketing and product spend rather than headcount. Mismatched assumptions in either column show up in payback.
