Fractional CFO for e-commerce software companies
E-commerce software contracts blend platform subscription with payments revenue share, app marketplace economics, transaction fees and merchant services. For the larger platforms, payments and ancillary make up the majority of gross profit, and merchant mix moves gross margin meaningfully.
GMV-driven modelling sits at the centre - take rate, payments penetration and ancillary attach all model off GMV cohorts, and merchant retention curves are built at cohort level rather than aggregated. Pass-through revenue reports net so software economics aren't quietly contaminated by low-margin volume.
Flow provides financial modelling, FP&A and fractional CFO advisory to e-commerce software companies across commerce platforms and storefront builders, headless and composable infrastructure, payments and checkout, post-purchase and logistics, and merchant financial services. We work as the outsourced startup CFO through growth, fundraising and sale processes.

Financial modelling for "e-commerce 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.
GMV-driven take rate
Take rate, payments penetration and ancillary attach all modelled off GMV cohorts rather than logo cohorts. The merchant who triples GMV is a different revenue trajectory than the merchant who adds three seats, and the model treats them as such.
Payments unit economics
Payments revenue reported net of processor, sponsor bank and interchange with gross margin built from the ground up. Pass-through volume reports net so software economics aren't contaminated by low-margin payments throughput.
Ancillary attach - apps, shipping, capital
App marketplace, shipping, fulfilment and merchant capital revenue reported as distinct expansion paths with their own margin and risk profile. The merchant-financial-services tail is valued differently and needs to be visible separately.
Merchant cohort retention
Cohort retention measured at merchant level by GMV band and segment, with downgrade, plan-tier movement and churn separated. Aggregated retention in this category systematically masks the SMB attrition that drives long-run economics.
Subscription ARR waterfall
Subscription bookings to billings to revenue separated cleanly from GMV-linked revenue and payments. Investors and acquirers can read the software business on its own merits before adding the payments and ancillary stack.
CAC payback by merchant segment
Fully-loaded CAC and payback by SMB, mid-market and enterprise merchant cohorts, with payments-attach lifetime value modelled in. The full unit economics only resolve once payments contribution is included alongside subscription.
