Total Operational Inflow
Definition
Sum of cash actually received from operating activities for the period — customer collections (subscription, services, transactional revenue), refunds claimed back from vendors, and any operating tax credits. Excludes financing activities (debt draws, equity proceeds) and investing activities (asset sales, investment income). This is the numerator-side of the net-burn equation, and the cash-basis counterpart to recognized revenue on the P&L. Common pitfall: companies sometimes book annual SaaS prepayments here as a single-month inflow, masking the underlying monthly run-rate — split lumpy items out or smooth over a trailing 3 months.
Why it matters
Inputs the cash-basis revenue side of net burn. A growing inflow at flat-or-falling outflow is the textbook "earning its runway" trajectory; the reverse means the company is more dependent on the cash balance than on revenue.
How it's calculated
Sum of operating-activity cash receipts for the period. Subtract from total_operational_outflow to get the absolute net-burn dollar value (before dividing by months to get the rate). How to interpret it
Reconcile against recognized revenue from `sales.arr` and bookings — a persistent gap means deferred-revenue or DSO is moving. Watch lumpy enterprise prepayments and isolate them; they distort the trailing-average net burn read.

Sum of cash actually paid for operating activities for the period — payroll and benefits, employer taxes, vendor payments (infra, tooling, contractors), sales and marketing spend, rent, professional services, refunds issued. Excludes financing activities (debt repayment, dividend payments) and investing activities (acquisitions, capex). Direct input to gross burn. Common pitfall: capitalized R&D and long-term capex sometimes get bucketed here; if so they distort gross burn. Keep this strictly operating-cash and surface investing/financing outflows separately so the board can see "ongoing cost base" vs. "discretionary capital deployment".
Average monthly net cash outflow over the reporting period — total cash spent minus total cash collected, divided by the number of months in the period. The headline survival number for venture-backed startups: it pairs with `finance.total_cash_in_bank` to produce runway, and pairs with revenue growth to produce the Bessemer "burn multiple". Common pitfall: net burn is volatile — large quarterly bills (annual SaaS renewals, employer-tax true-ups), enterprise prepayments, and FX swings can mask the underlying trend. Smoothing over a trailing 3-month average is standard board practice. Equally important: do not silently include one-off cash events (acquisitions, settlements, large prepayments received) without flagging them — boards prefer a "core burn" and "headline burn" pair when the period is noisy.
Signed net effect on cash of changes in current assets and current liabilities — receivables coming in (positive), payables going out (negative), prepaid expenses (negative when paid, positive when burned down), and accrued liabilities (positive when accrued, negative when settled). The rollup of `finance.current_asset_adjustments` and `finance.current_liability_adjustments`. Common pitfall: at early stage this is dominated by payroll-cycle noise and is near zero — once the company adds enterprise contracts with annual prepayments or 60-day net terms, this can swing 1–3 months of burn either direction. Becomes material at Series A+; ignored before that.
Annual Recurring Revenue — the value of all recurring subscription revenue normalized to a one-year run-rate as of the period close. The headline operating metric for a subscription business; every growth and efficiency ratio (NRR, GRR, magic number, CAC payback, Rule of 40) is calibrated against it. Excludes one-time fees, professional services, and non-contractual usage. Common pitfall: confusing ARR (contracted recurring) with revenue (recognized) or with CARR (contracted incl. not-yet-live) — the SMSB standard draws sharp lines between them, and boards expect the same discipline. The KpiVarianceTable widget surfaces forecast / actual / variance / status / future-forecast columns against the same field.
