Fractional CFO for productivity software companies

Productivity software is heavily PLG-led, with self-serve sign-up, free tiers and team-to-enterprise expansion at the centre of the GTM. The accounting isn't difficult, but the metrics question is - paid conversion, team expansion, edition mix and active-user definitions all need consistent treatment.

The model respects how PLG actually behaves rather than retrofitting a sales-led shape onto it. Self-serve and sales-assisted economics report separately with their own payback profiles, and the cost of supporting the free funnel - infrastructure, AI compute, support - is made explicit.

Flow provides financial modelling, FP&A and fractional CFO advisory to productivity software companies across notes, docs and wikis, task and project management, calendaring and scheduling, no-code and workflow automation, and AI-native productivity tools. We work as the outsourced startup CFO through growth, fundraising and sale processes.

Team expansion

ARPU per seat

CAC payback

Gross margin

Edition mix

Financial modelling for "productivity 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.

PLG funnel model

Self-serve sign-up to active team to paid conversion to enterprise contract tracked as a cohorted funnel over twelve to twenty-four months. The model respects how PLG actually behaves rather than retrofitting a sales-led shape onto it.

Free-tier infrastructure cost

Infrastructure, AI inference and support cost of the free funnel made explicit in gross margin reporting rather than buried in a blended COGS. The cost of supporting unpaid users is treated as a customer-acquisition investment with its own ROI.

Team-to-enterprise expansion

Expansion tracked at team-within-account level with conversion rates from team plan to enterprise contract by cohort. Logo-level NDR collapses the team expansion engine that creates most of the lifetime value in PLG businesses.

Active-user & DAU/WAU model

Active-user definitions held consistent across paid and free tiers, with DAU, WAU and engagement-cohort trajectories modelled by acquisition source. Engagement is the leading indicator of paid conversion and the metric most easily distorted by sloppy definitions.

Seat ARR & edition mix

Paid seat ARR walked by edition mix, with ARPU-per-seat movement decomposed from raw seat growth. Edition uplift is a distinct expansion lever from net new paid seats and the model treats them as such.

Self-serve vs sales-assisted P&L

Self-serve and sales-assisted cohorts reported with their own CAC, payback and gross margin profile. Most PLG businesses develop a sales-assisted enterprise layer over time, and the two motions need to read separately well before a process starts.
