Why Your P&L Doesn't Match Your Bank Account

Why Your Profit and Loss Doesn't Match Your Bank Account

Your P&L says you made money but your bank account says otherwise. Here's what causes the gap on cash-basis books, and when it's actually a problem.

Your profit and loss report says you made $18,000 last month. You open your bank app and there's $4,000 sitting there. Nothing is broken. Both numbers can be right at the same time.

This is one of the most common questions business owners ask, and the answer is simple once you see it: a profit and loss report and a bank balance measure two different things.

What each report is actually telling you

Your profit and loss shows what you earned and what you spent running the business over a period of time. One month, one quarter, one year.

Your bank balance is a running total of every dollar that moved in or out — including a lot of money that has nothing to do with profit.

That second part is where the gap comes from.

Money that leaves your bank but never shows up as an expense

Loan payments on your truck or equipment. If your truck payment is $900 a month, only part of that is an expense. The interest is. The rest is paying down what you borrowed, and paying off a debt is not a cost of doing business. Your bank drops $900. Your P&L might only show $120.

Money you pay yourself. Owner draws are not an expense. You are not an employee buying something for the business — you are taking your own money out. It leaves the bank and never touches the profit and loss at all.

Buying equipment. Spend $30,000 on a new truck and your bank feels it right away. Your profit and loss does not. A purchase that big goes on your balance sheet, and it works into your P&L a piece at a time over several years. That is depreciation. Your tax return may treat it differently, and that is a separate question from how it sits in your books.

Money that comes in but isn't income

Sales tax you collect. When you charge a customer sales tax, that money is not yours. You are holding it for the state. It sits in your bank and makes you look better off than you are, right up until you send it in.

Loans and transfers. Borrowing $20,000 puts $20,000 in your account. You did not earn it. Same with moving money between your own accounts — the balance changes, the profit does not.

Expenses that show up before the money leaves

This one runs the other direction. Buy $3,000 of materials on a credit card and that cost hits your P&L right away, because that is when you incurred it. But the money does not leave your bank until you pay the card, maybe next month.

So your P&L can show an expense your bank has not felt yet.

The report you're missing

The profit and loss only tells half the story. The other half is on your balance sheet — what you own, what you owe, and what you have taken out. Loan balances, equipment, sales tax you are holding, owner draws. All of it lives there.

Read the two together and the gap stops being a mystery. Your P&L tells you whether the work is making money. Your balance sheet tells you where the money went.

When the gap IS a problem

A difference between the two reports is normal. Not being able to explain it is not.

If you cannot point to the loan payments, the draws, the equipment, and the sales tax and watch the two numbers line up, then something is categorized wrong. That is worth fixing before tax season, not during it.

That is the actual job: every charge in the right place, every account matched to its statement, every month. When the books are kept that way, the gap between your profit and your bank balance is always explainable — and usually in about thirty seconds.
