Operationally Available Cash

Cash that the company can freely deploy for any operational purpose — total bank balances minus any contractually restricted balances. This is the input most boards actually want when judging runway, because it strips out escrows, security deposits, and processor reserves that cannot be spent on payroll or vendors. The distinction matters more as the company adds enterprise contracts (deposit obligations), debt facilities (covenant balances), and payment processing volume (rolling reserves). Common pitfall: at early stage, restricted cash is often near zero so teams equate this with `finance.total_cash_in_bank` — track them separately from day one to avoid surprise reclassifications later.

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.

Signed cash effect of period-over-period changes in current assets — accounts receivable, prepaid expenses, deposits, and other short-term assets. Positive when assets are converting back to cash (AR collections, prepaid expenses being consumed); negative when assets are growing and absorbing cash (AR balance up, new prepayments made). Half of the `finance.net_working_capital_adjustment` rollup. Common pitfall: a one-off enterprise prepayment to a vendor (e.g. 12-month infra commit) shows up here as a large negative without the P&L showing the cost yet — flag it explicitly so the board does not read deterioration where there is none.

Signed cash effect of period-over-period changes in current liabilities — accounts payable, accrued payroll/taxes/bonuses, deferred revenue from customer prepayments, and other short-term liabilities. Positive when liabilities grow and absorb less cash than the matched expense suggests (e.g. AP balance growing means vendor cash payments lag); negative when liabilities are being paid down faster than they accrue. Deferred revenue is the most powerful component in SaaS — a large annual prepayment received increases deferred revenue and supplies cash now against expense recognized later. Common pitfall: a board reading this as straight cash improvement misses that deferred revenue must still be earned out, and a stretched AP balance signals supplier strain. Best practice: footnote large components (deferred revenue, accrued bonus) separately.

Estimated number of months the company can operate at the current net burn before unrestricted cash reaches zero, holding everything else constant. The single most consequential survival input for venture-backed companies — it sets the urgency of every fundraising, hiring, and cost decision. Common pitfall: runway is often quoted off `finance.total_cash_in_bank` and a single-month spot-burn instead of operationally-available cash and a 3-month-trailing burn — the result is a runway that looks 2–4 months longer than it actually is when working capital tightens. Boards should ask which cash and which burn went into the calculation.
