Your P&L Says You Made Money. Your Bank Account Disagrees.
Your P&L tells you what you earned. Your bank balance tells you what landed. Those are different questions with different answers, and the gap between them is where most businesses get into trouble.
Revenue is recognized when you send the invoice. Cash arrives when the customer decides to pay it. In between sits every payroll you have to make regardless.
The number that explains it is billed versus collected, tracked monthly. Almost nobody produces that report, which is why the question keeps coming as a surprise.
Four things that create the gap
When an owner tells me the P&L is lying, it is almost always one of these, and often several at once.
1. Timing. You invoiced $250,000 in March. You collected $180,000 in March, some of it against January and February invoices. March profit looks great, March cash does not. Nothing is wrong. Accrual accounting is doing exactly what it is supposed to do.
2. Things that consume cash but never touch the P&L. This is the one that genuinely surprises people. Paying down loan principal is not an expense. Buying equipment is not an expense, it capitalizes and comes back as depreciation over years. Owner draws are not an expense. Building inventory is not an expense until you sell it. All four move real money out of your bank and none of them reduce your reported profit.
3. Things that hit the P&L but never touch cash. Depreciation and amortization reduce your profit without any money leaving. Accrued expenses you have booked but not paid do the same. So the mirror image happens too: a business showing a loss can be building cash.
4. Growth. The cruel one. Growing companies get squeezed hardest, because every new job means paying labor and materials now against an invoice that collects in 45 days. The faster you grow, the wider the gap. Plenty of profitable companies have run out of money in a good year.
Billed versus collected, month by month
One chart answers the question. Bill amounts on one axis, collections on the other, twelve months across the bottom.
What you are looking for is not the individual months, because those bounce around. It is the pattern.
- Collections consistently below billings means either your collection process is not working or you are booking revenue on work that is not genuinely billable yet.
- Collections spiking well above billings in a month usually means a backlog cleared, which feels great and tells you nothing about the underlying trend.
- A widening gap over several months is the warning. That is receivables aging, and receivables aging is the single most reliable early signal that a cash squeeze is coming.
Then reduce it to one number. Total collected divided by total billed, year to date. Call it your conversion rate. A business converting 93 cents on the dollar over a year has a working collection process. A business at 78 cents has a problem it has not named yet.
The report that actually answers it
The statement of cash flows exists precisely for this, and almost no small business owner ever reads one. It starts with net income and walks you down to the change in your bank balance, line by line, showing exactly where the difference went.
Net income at the top. Add back depreciation. Adjust for the change in receivables, which is cash your customers are still holding. Adjust for inventory and payables. That gets you cash from operations. Then investing, which is the equipment you bought. Then financing, which is the loan principal and your draws. Bottom line is the change in cash.
Read it once and the mystery is gone. You are not guessing anymore, you are looking at the arithmetic.
The catch is that QBO will generate one on demand and it will be worthless if your balance sheet is not clean. Cash flow is derived from period-over-period balance sheet movement. Unreconciled accounts, misposted loans, and inventory that was never counted all flow straight into the report as nonsense. A cash flow statement is only as good as the balance sheet underneath it, which is why most owners look at one, find it confusing, and never open it again.
What to do about it
- Produce billed versus collected every month. Not annually. Monthly, with the prior twelve visible, so you see the trend rather than the month.
- Age your receivables and actually work them. Most collection problems are not difficult customers, they are invoices nobody followed up on.
- Get the balance sheet reconciled so the cash flow statement means something.
- Separate the non-P&L cash uses and look at them monthly. Principal, capex, draws, inventory build. That total is money gone that your P&L never mentioned.
- Forecast thirteen weeks out. Expected collections against known obligations, rolled forward every week. It is the single most useful report a small business can run and almost none of them do.
None of this requires new software. It requires the books to be right and someone to look at the same four things every month.
