Details
Sales are not the same as cash in the bank if customers pay later or bills are due sooner.
Owner draw can make a profitable business feel cash-tight when it is not included in planning.
Self-employed owners often need to reserve cash for estimated taxes instead of treating all revenue as spendable.
The 30, 60, and 90 day cash preview makes timing pressure visible before hiring, spending, borrowing, or taking a larger draw.
After checking cash timing, inspect payment terms, invoice process, runway, profit margin, and client profitability before changing spend.
Benchmarks
A broad planning signal that monthly revenue covers expenses, owner draw, and tax reserve.
If monthly net cash is negative, less than six months of runway deserves closer planning.
A broad operating reserve benchmark, not a rule for every business model.
