Your P&L says you made money last month. So why did Friday's payroll feel so close?
It's one of the most common surprises we see with growing businesses, and it comes from a simple fact: profit and cash move on different schedules. Revenue is recorded when you earn it. Cash arrives when the customer pays. Expenses hit when they're incurred, but bills, payroll, loan payments and taxes leave the bank on their own calendar.
One customer paying 30 days late plus one large bill paid early can turn a profitable month into a very tight one. Of all the forward-looking tools we use with clients, the cash forecast is often the one that matters most.
What a cash forecast is (and isn't) A cash forecast looks out a short distance, usually up to 13 weeks. Sometimes the horizon is the next month. Sometimes it's just "can we get through the next payroll?"
It doesn't ask whether you're profitable. It asks one question: what's coming into the bank account, what's going out, and when?
How it's built The structure is intentionally simple. Unlike a budget or forecast, which follow your P&L accounts line by line, a cash forecast uses a handful of broad categories so it's easy to update every week.
Start: this week's beginning bank balance
Cash in: customer collections, draws on a line of credit, owner contributions
Cash out: vendor bill payments, payroll, rent, debt service, credit card payments, tax payments, owner distributions
End: projected bank balance at the end of the week, which becomes next week's starting point
Roll that forward week by week, and you can see the lumpy weeks before you're in them: the payroll week that lands before a big collection, the quarter-end tax payment, the month with three paydays.
What it lets you do When you can see a crunch coming, you have options:
Sort payables into must-pay and can-wait. Payroll and rent drafts can't move. Some vendor payments can go out a week later without harm.
Follow up on collections early. Often the forecast is fine as long as two specific customers pay on time. Knowing that tells you who to call.
Plan line-of-credit draws instead of scrambling for them.
Talk to your bank from strength. A lender is far more comfortable extending credit when you can show a budget, a forecast and a cash plan that explain why you need it and how it gets repaid.
Get it out of your head Many owners run a cash forecast in their heads. They know the balance, they know payroll is Friday, they know which customer is slow. That's impressive, and it works, until the business grows and too many things are moving through the account at once.
Growth consumes cash. Putting the forecast on paper, updated weekly, is how you keep growing without being surprised.
