Understanding Your Business Cash Flow

A profitable business can still run short of cash. A cash forecast shows when money is expected to arrive and when it must leave.

Updated September 20, 2026

Separate profit from available cash

An unpaid invoice is not money in your bank account. Loan principal payments, owner withdrawals, and equipment purchases also affect cash differently from the expenses shown on a profit-and-loss statement.

Build a weekly forecast

Start with available cash. Add expected customer receipts by collection date, then subtract payroll, rent, suppliers, debt payments, and planned tax payments. Track the ending balance each week over the next few months.

Use the forecast to act early

Compare actual collections with your forecast. Follow up on overdue accounts, review inventory commitments, and discuss payment timing before a shortfall occurs. Keep a separate reserve for obligations already incurred.

A practical example

You start with $12,000, expect $8,000 in collections, and have $23,000 of payments due. That leaves a $3,000 gap, even if your sales report looks strong. Delayed collections would make the gap larger.

What to gather
  • Current bank balances
  • Unpaid invoices and their expected collection dates
  • Upcoming bills, payroll, and loan schedules
  • Expected tax payments and major purchases
