You closed the month with more revenue than costs, and the checking account holds less than it did on the first. Both facts are true at the same time, and the reason is almost never fraud or an error. Profit and cash answer two different questions, and only one of them pays the rent.
What follows is the order a bookkeeper works through when someone brings in that month, written as the questions themselves. They are worth asking yourself before you pay anyone else to ask them.
When did the money actually leave?
Most profit and loss statements are built on accrual accounting, which records income when you earn it and costs when you incur them, whatever the bank is doing that week. The statement says you earned it in March because that is when you finished the work. The bank says the customer paid in May. Neither is lying.
Plenty of small operations file taxes on a cash basis, where income counts when it arrives, and then run their management reports on accrual because that is what the software does by default. If nobody has told you which one you are looking at, that is the first thing to establish. The two versions of the same month can look nothing alike, and arguing about a number without knowing which basis produced it wastes an hour.
What is sitting in receivables?
Accounts receivable is work you have done, billed, and not been paid for. It counts as income on the statement and as nothing at all in the bank. A growing business almost always has a growing receivables balance, which is exactly why growth can drain an account that was fine when things were slow.
Ask for the aging, meaning the same list sorted by how old each unpaid invoice is. What matters is not the total, it is the shape. If most of what is outstanding is under thirty days, you have a timing problem and it will resolve. If a meaningful share has crossed ninety days, some of that is not a timing problem, it is a collection problem, and it should stop being counted as money you expect.
Did you buy something the statement will not let you expense?
A truck, a compressor, a cargo trailer. Cash leaves in one lump, and the cost gets spread across several years as depreciation, so the statement only shows a slice of it. That gap is one of the two most common answers to the question this piece opens with.
The other is loan principal. The payment leaves your account whole, but only the interest portion counts as an expense. Everything else is you handing back borrowed money, which was never income. On a newer loan that split is heavily weighted toward principal, so a payment that feels enormous barely registers on the statement. None of that is an accounting quirk somebody invented. The IRS deliberately treats a truck and a box of fittings differently, recovering the cost of one across years and letting you deduct the other in the month it is bought, and the statement is only reporting that choice back to you.
What did the owner take out?
Money you take out of a sole proprietorship or a partnership is a draw, not an expense. It reduces the bank balance and leaves the profit figure untouched, which is correct and still surprises people every year. If the business is set up as an S corporation you are supposed to be running reasonable wages through payroll, and those do show up as an expense, so the same withdrawal lands in a different place depending on a structure choice you may have made years ago without thinking about this.
The practical consequence is that owners of unincorporated businesses routinely look at a profit figure, feel reassured, and forget that the number is calculated before they eat. If you want the statement to tell you the truth, write down what you actually need to take out each month and subtract it yourself before you decide the business is doing well.
What else quietly holds cash?
Two more places, and they are the ones people forget to look at because neither appears on a profit and loss statement as a line you would notice.
Inventory is the obvious one for anyone who stocks parts or materials. Cash converts into shelves. The statement records nothing until the part is sold or installed, so a month spent building up stock ahead of a busy season looks identical to a good month, right up until the bank tells you otherwise. Anyone who bought in quantity to catch a supplier discount has felt this without necessarily naming it.
The other is prepaid costs, which means anything you pay for in advance and use up over time. An annual insurance premium, a year of software, a license renewal. The money is gone in January and the expense is spread across twelve months, so January looks unusually profitable and unusually broke at the same time. Neither figure is wrong. They are answering different questions, which is the theme of the whole exercise.
What do the next sixty days look like?
The most useful spreadsheet in a small business is also the ugliest one. Eight columns, one per week. Opening balance, deposits you actually expect, payments you actually owe, closing balance. Not forecasts, not averages. Named invoices and named bills.
Two things fall out of it immediately. You find the week that goes negative, usually five or six weeks out, while there is still time to move something. And you stop treating the current balance as a measure of how the business is doing, because you can see what is already claimed.
Which of these can you fix this month?
Not the depreciation and not the loan. The ones within reach are the invoice you send four days after the job instead of the same afternoon, the deposit you stopped asking for because one customer once pushed back, and the terms you inherited from whoever you worked for before you went out on your own. Those three move cash without changing a single thing about the work.
A month that looks good and feels bad is usually telling you something specific. It is worth finding out what, because the answer is generally a habit rather than a crisis.
