Desktop cash-flow workspace
Find out which month kills your business — before you sign anything.
CashRunways models the cash curve of a real business across 6 to 36 months: tax, payment fees, returns, restocking, churn, capacity and the way your cost per customer quietly rises every time you double ad spend. Then it tries to break it.
Three engines, one model
Inventory, subscription and service businesses behave nothing alike. Stock ties up cash before revenue; SaaS pays for a customer a year before they pay you back; agencies hit capacity walls. Each gets its own maths.
Break-first stress tests
Every plan survives on paper. CashRunways raises CAC 40%, doubles returns, adds churn — and tells you which single assumption kills you soonest, and in which month.
Close the month, re-forecast
Log six real numbers each month. CashRunways grades each variance by how much data stands behind it, flags direction that repeats, and rebuilds the rest of the year from what you measured.
Start with the model
Pick a country and a category, set your assumptions, and read the cash curve. Premium adds the graded scorecard, stress tests, monthly close with variance grading, an AI review and saved scenarios.
