Profit Is Not Cash

Short Answer: Profit counts what you earned in a period. Cash counts what actually moved through the bank. They drift apart for four common reasons: customers paying later than you bill them, buying supplies ahead of use, spending on equipment or loan principal (which barely touch profit), and money the owner takes out. Trace each one and your profit reconciles to your bank balance to the dollar.

Almost every owner hits this month eventually. The profit and loss statement says the business made $10,000. The bank account says there's less money than there was 30 days ago. Nothing is wrong with the books. The two numbers answer different questions, and the gap between them is the most useful thing on your financials to understand.

What Does "Profit" Actually Measure?

Profit is revenue minus expenses for a period, recorded when the work happens. If your books use accrual accounting (revenue counted when you earn it, not when you're paid), a job you finish and invoice in April is April revenue, even if the check arrives in May.

That makes profit a good measure of whether the business works: are you charging enough, and are your costs under control? It is a poor measure of whether you can make payroll on Friday.

What Does "Cash Flow" Measure?

Cash flow is simply money in minus money out of your bank accounts. It doesn't care when the work was done or what the spending was for. A customer payment for last month's job is cash in. A new mower is cash out, all at once, on the day you pay for it.

A Worked Example: One April at a Landscaping Company

Take a hypothetical landscaping company, Greenline Landscaping: one owner, a crew of four, two trucks, about $520,000 a year in revenue. Residential clients pay on completion. Commercial clients pay 30 days after the invoice.

Here is Greenline's April profit and loss statement:

And here is what happened in the bank account the same month:

A $10,000 profit, and the account fell by $25,500. Here is where every dollar went.

Where Did the Profit Go?

1. Customers Haven't Paid Yet

Greenline billed $48,000 in April. Residential clients paid their $20,000 on the spot. The $28,000 billed to commercial clients won't arrive until May. The company did collect $9,000 on March's commercial invoices, so cash in was $29,000 against $48,000 billed.

Money you've billed but not collected is called accounts receivable. When it grows, it soaks up cash. Here it grew by $19,000.

2. Supplies Bought Ahead of Use

The P&L only counts the $12,000 of materials that went into April jobs. Greenline actually bought $16,000, stocking $4,000 of mulch and plantings for May. That $4,000 is still sitting in the yard as inventory. It's an asset, not an expense, so it doesn't lower profit. It does lower cash.

3. Equipment and Loan Principal

The $7,000 mower left the bank in one payment. On the P&L, its cost is spread over the several years the mower will work (called depreciation), so April shows only a sliver of it.

Loan payments split in two. The interest is an expense, already inside the $6,000 line above. The principal (the part that pays down what you borrowed) isn't an expense at all, so the $1,500 never appears on the P&L.

4. Money the Owner Took Out

In a sole proprietorship or single-member LLC, an owner's draw isn't a business expense. It's the owner taking part of the profit home. So the $4,000 comes out of cash but not out of profit. (If the business is an S-Corp paying the owner a salary, that salary is an expense and does show up on the P&L.)

Putting It Back Together

Start from profit and walk each gap. You land exactly on the change in the bank account:

This walk is what a cash flow statement does, and it's why accountants produce one next to the P&L. Once you've done it for a month, a low balance stops being a mystery and becomes a list of decisions: chase the $28,000 of commercial invoices, buy May's materials in May, or put the mower on a payment plan.

What to Look For

• How long customers take to pay, against your terms. If your terms are 30 days and the average invoice takes 50 to collect, you're lending your customers three weeks of work.
• Cash on hand against the next four weeks of fixed bills. Payroll, rent and loan payments don't wait for collections. Below four weeks of cover, one late client becomes a crisis.
• A gap you can't explain. A walk that doesn't land on your bank balance usually means a bookkeeping error, and it's worth finding before you make decisions on those books.

What a Finance Consultant Would Do Next

A consultant looking at Greenline's April wouldn't stop at the walk. They'd pick out the gaps that are really decisions: whether commercial contracts should require a deposit, whether the mower should have been financed, and how large a draw the business can support across the whole season rather than one month. Then they'd model each option against the rest of the year before recommending one.

That analysis is what Occam's Model runs on your own books. It builds this walk from the files you already keep and lets you test a change, such as asking customers to pay faster, against your numbers before you make it. When you need extra help, an expert can review it with you.

Common Questions

Can a profitable business run out of money?
Yes, and growing businesses do it most often. Each new customer on payment terms adds unpaid work to receivables before the cash arrives. A business can be profitable every month and still miss payroll.

Does this mean my bookkeeping is wrong?
Usually not. If your books are on accrual, profit and cash are supposed to differ. The warning sign is a gap you can't explain, not the gap itself.

Would cash-basis accounting make the two numbers match?
Closer, but not all the way. Cash-basis books count revenue when it's collected, which removes the receivables gap. Equipment purchases, loan principal and owner's draws still don't show up as expenses.

How often should I check profit against cash?
Monthly, after the books close. In your busy season, look at receivables every week.
