Your business is profitable on paper. So why is there no cash in the bank?
Your profit and loss statement says the business made money last quarter. Your bank account says otherwise, and payroll is due Friday. It’s a disorienting position, and a very common one. Profit and cash measure different things, and the gap between them explains more small-business cash crunches than lack of sales ever does.
Profit is earned; cash is collected
Profit, as shown on an income statement, measures what the business earned in a period: revenue minus the expenses that relate to that revenue. Cash flow measures what actually moved in and out of the bank account.
Those two can match closely in a simple cash business, like a café paid at the register. In many businesses, they don’t, because the timing of earning and the timing of paying are different.
Where the gap comes from
The most common reason is unpaid invoices. Imagine a small agency that completes $30,000 of client work in March and pays $22,000 in salaries and costs that month. Its March profit is $8,000. But clients have 60 days to pay, so March’s cash flow is −$22,000. The profit is real; the money just hasn’t arrived.
Inventory works the same way in reverse. A business that buys $15,000 of stock to sell over the next few months has spent the cash now, but the cost only shows up as an expense as the stock is sold.
Equipment purchases spread out too. A $12,000 machine expected to last five years is usually recorded as an expense of $2,400 a year through depreciation, while all $12,000 leaves the bank on the day it’s bought.
Loan repayments are the reverse case. The interest on a loan is an expense, but the part of each payment that repays principal isn’t, so it reduces cash without reducing profit. A business paying $1,000 a month in principal has $12,000 a year less cash than its profit suggests.
Owner withdrawals don’t appear as expenses either, for most small businesses. Money you take out to live on reduces cash but not profit.
And taxes are owed on profit, whether or not the cash has come in.
Why growth can make it worse
Growth often widens the gap. More sales mean more invoices waiting to be paid, more inventory to buy in advance and sometimes more equipment. A business growing quickly can be more profitable each month and have less cash each month, until it can’t pay its bills. This is why lenders and experienced owners watch cash as closely as profit.
What to watch
The cash flow statement shows where cash came from and where it went, alongside the income statement that shows profit. Looking at both each month shows whether profit is turning into cash.
A few habits help. Track how long customers take to pay, and follow up on overdue invoices promptly. Ask for deposits or shorter payment terms on large projects. Plan inventory and equipment purchases around expected cash, not just expected sales. Keep a cash cushion for the gap between doing the work and getting paid.
The business runway calculator shows how long current cash lasts at your monthly burn, and the break-even calculator shows how many sales cover fixed costs. For how the timing of revenue is recorded, see cash vs. accrual accounting.
The takeaway
Profit tells you whether the business is earning more than it costs. Cash flow tells you whether you can pay the bills this month. A business needs both, and watching only profit can leave you caught out by unpaid invoices, inventory, equipment and loan payments that profit doesn’t show.
