Cash flow
Profitable but broke: why your bank balance disagrees with your P&L
By Elizabeth Miller, Owner & Principal Bookkeeper · Published April 7, 2026 · 7 min read
Perhaps the most common call we get in a first year of working together starts the same way: “The P&L says we made $48,000 last quarter. Why is there $6,000 in the account?”
The profit and loss statement measures earning. The bank account measures timing. Six things typically live in the gap.
1. Receivables
Revenue is recorded when you invoice, not when you are paid. Thirty days of sales sitting in receivables is thirty days of profit you cannot spend. If your average collection period drifts from 32 to 47 days, roughly half a month of revenue silently leaves your bank account.
2. Inventory
Cash converts into stock, and stock is not an expense until it sells. A growing business that buys ahead of demand can be highly profitable on paper and short of cash every single week.
3. Debt principal
Only the interest portion of a loan payment appears on the P&L. The principal reduces a balance sheet liability. A $2,400 monthly payment might show as $310 of expense while $2,090 leaves the bank.
4. Capital purchases
A $30,000 van is not a $30,000 expense. It is an asset depreciated over years — but the cash left in one transaction.
5. Owner draws and distributions
Distributions are not expenses. They never appear on the P&L, and in owner-managed businesses they are frequently the largest single outflow of the year.
6. Sales tax and payroll withholding
Money you collected on someone else's behalf sits in your account looking like yours. It is a liability. Treating it as working capital is the fastest route to a penalty notice.
The report that fixes this
A statement of cash flows reconciles net income to the actual movement in your bank balance, and it is produced by every serious accounting system. Most small businesses never look at it. We include it in every monthly pack, together with a 13-week rolling forecast on our Growth and Controller plans.
A practical habit
Once a month, put three numbers side by side: net profit, change in bank balance, and change in receivables plus inventory. When the first two diverge, the third almost always explains it. That five-minute check has prevented more crises among our clients than any piece of software.
