Why Is My Trades Business Profitable on Paper but Broke in the Bank?
By Doug Johnson, CPA - Updated August 2026
It sounds counterintuitive - but a lot of the items that impact your business's cash flow never hit your P&L. Most small trades businesses keep cash-basis books, which means the P&L only counts revenue you've actually collected and expenses you've actually paid - so the profit number isn't inflated by unpaid invoices or anything phantom. The money is really gone. It just went to things that aren't expenses: your draws, your estimated taxes, loan principal, and equipment. If you've ever looked at a profitable P&L and wondered why your business bank balance is lower than you'd expect, this article walks through exactly where the cash went.
Where the cash actually goes
Four places, in rough order of how often we find them when we dig into a trades client's books:
- Owner draws and estimated taxes. Your draws aren't an expense - they never touch the P&L. Neither do the quarterly estimated tax payments you're making on that profit. For a healthy trades business, these two are usually the single biggest gap between "what the P&L says" and "what the bank says," and owners are routinely shocked at how much they add up to over a quarter.
- Loan principal. Only the interest on your truck and equipment loans hits the P&L. The principal portion of every payment isn't an expense, it's a liability paydown - but obviously it still impacts your bank balance. Two or three financed trucks can quietly pull ~2 - 3K a month that "profit" never accounted for.
- Equipment bought with cash. Pay 24K for a used van and the P&L won't reflect it until year-end - the purchase gets capitalized, and the expense either gets accounted for in December using bonus depreciation, or trickles in as depreciation over years. Note that this cuts both ways: depreciation on gear you bought in prior years (assuming no bonus depreciation was used) is an expense with no cash attached, which is why your P&L and bank account drift apart in both directions.
- Credit card paydowns. On cash-basis books, card charges count as paid when you swipe - so the expense already hit. When you later pay down the balance, that's a liability paydown with zero P&L effect. A business digging out of a card balance can look great on paper while the account drains.
How you fix it
The fix follows the same progression we recommend for trades bookkeeping generally: current books first, real monthly cash visibility second, job-level numbers third.
- Get the books current first. First things first, you need your books reconciled within the first couple weeks of month-end, not reconstructed at tax time or sometime during the quarter. You can't manage a cash gap you find out about 3 months later. Everything else depends on this.
- Read a comparative balance sheet and run a cash forecast. The P&L can't show you draws, loan principal, equipment purchases, or card paydowns - the balance sheet is where that info lives. At least quarterly, you should be reviewing your balance sheet and comparing it against the prior period - this will allow you to see changes in loan balances, new draws, etc. Over time, you should also work (or have your CPA work) to build out a cash flow forecast that you can use for forward-looking planning.
- Work toward job costing. Tagging labor, materials, and subs to each job tells you your margin per job, not just company-wide - and which jobs generate cash vs. consume it. This isn't essential at 100K in revenue, but becomes critical as you scale. Do note, though, that this is impossible without tight bookkeeping and good operational systems.
FAQ
Is this a sign my prices are too low? Not necessarily - a pricing problem shows up as thin margins on the P&L itself. What we're describing here is healthy profit with cash leaving through doors the P&L doesn't watch: draws, taxes, principal, equipment. That said, both can be true at once, and job costing can help you tell them apart.
Would switching my books to accrual show me this sooner? It shows you a different piece of the picture - accrual-style management reports make receivables and work in progress visible, which matters more as your jobs get bigger. But most small trades businesses correctly stay cash-basis for tax purposes, and you can do both: cash for the tax return, accrual-informed reporting for running the business.
I financed a truck and took Section 179 - why did my profit crater but my cash barely moved? That's this article's problem running in reverse. Section 179 and bonus depreciation front-load the deduction into year one while the financing spreads the cash out over five or six years - so you get a big paper expense with almost no cash out. The catch comes later: in years two through five you're making real loan payments with no deduction left to show for them, which is exactly when owners start asking the question in this article's title.
How much cash should I keep in the business? A common target in the trades is 1 - 2 months of operating expenses, more if your work is seasonal or your customers pay slow. The right number can be determined by building out a detailed cash forecast, which is a better guide than any rule of thumb.
Can't I just take fewer draws? That helps the symptom more than the cause - and you still have to live. The durable fixes are on the billing and collection side, plus knowing your real numbers monthly. Cutting draws can work in the short-term but isn't sustainable over the long-term, as it eats into your living expenses and lifestyle.
