Fractional CFO for smart home companies
Smart home blends consumer electronics economics with a subscription overlay. Connected cameras, locks, sensors and hubs sit on a hardware P&L; recurring monitoring, storage and software fees behave like SaaS. The category has consolidated around a handful of platforms across security, lighting, climate and the broader connected stack.
The valuation question is whether the subscription book ever pays back a hardware-margin-negative launch, and the model has to be honest about it. That means attach-rate and churn tied to specific cohorts, deferred revenue and ratable recognition on multi-year service plans, warranty and replacement reserves, and an LTV-to-CAC view that separates device from service.
Flow provides financial modelling, FP&A and fractional CFO advisory to smart home companies across security and monitoring, climate and energy, lighting and access, connected appliances and platform layers. Our startup CFO work runs hardware and subscription as two unit-economics views that reconcile, not blend.

Financial modelling for "smart home" 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.
Hardware vs subscription unit economics
Device gross margin and subscription gross margin modelled as two separate unit-economic views that reconcile to one P&L. The valuation question is whether the recurring book pays back a margin-negative device launch.
Attach rate and subscription cohort retention
Subscription attach at point of sale, activation, and renewal modelled by device cohort, with churn curves by month and tier. Tells you whether the recurring revenue actually compounds or just resets each hardware cycle.
Deferred revenue and ratable recognition
Multi-year service plans, prepaid subscriptions and lifetime licences modelled into deferred revenue with monthly ratable recognition. Surfaces the gap between cash collected and revenue recognised that diligence will check first.
LTV / CAC with device-and-service split
Customer LTV built from device margin plus subscription margin over expected lifetime, against fully-loaded CAC. Stops blended LTV from hiding a subscription book that never reaches payback.
Warranty, replacement and platform-risk reserves
Warranty accrual, in-warranty replacement, and reserves for end-of-life of integrations with third-party platforms (Alexa, HomeKit). Captures the categorical risk that a platform partner kills a SKU mid-cycle.
BOM and component-cost sensitivity
Component-level BOM, freight and tariff sensitivities modelled against pricing and pack-out cycles. Margin moves quarter to quarter on chip and sensor cost before retail pricing can be reset.
