Cash flow is the money moving in and out of your business right now. Profit is what your books say you earned after expenses. You can be profitable on paper and still not make payroll on Friday. That's cash flow, and it's the #1 reason good businesses stumble.
The classic trap
You land a $20,000 job. Feels great. You buy materials ($8,000), pay your crew ($6,000), and invoice the client Net 30. For the next month, you're "profitable" but your checking account is screaming.
Three numbers worth watching weekly
- Money in — payments received this week
- Money out — bills, payroll, materials, subscriptions
- Outstanding — invoices sent but not paid yet
That's it. You don't need a CFO to start. You need visibility.
Habits that help
Invoice fast, collect faster. See our guide on getting paid faster.
Build a buffer. Aim for 1–2 months of operating expenses in the bank. Slow seasons happen.
Match timing. Don't pay for materials 60 days before the client pays you. Deposits and milestone billing exist for a reason.
Watch recurring costs. Subscriptions add up quietly. Audit quarterly.
