Profitable on paper, short on cash: where the money actually goes

One of the most common questions I hear from business owners is some version of this: "My CPA says we had a good year. Why does cash always feel tight?" It is a reasonable question, and in most cases nothing is wrong. Profit and cash are simply measured in different ways, and the gap between them tends to widen as a business grows.

In corporate finance, this gap is managed deliberately. Large companies track working capital as closely as they track sales, because they know that a profitable company can still run out of cash. The same principles apply to a $2M service business. They are just rarely explained to owners in plain terms.

Profit and cash measure different things

On an accrual-basis profit and loss statement (P&L), revenue is recorded when earned and expenses when incurred. Your bank account records money when it actually moves. If you finish a $50,000 job in March and the customer pays in May, an accrual P&L records the revenue in March while cash arrives in May. A cash-basis P&L follows receipts and payments more closely, but still differs from your bank balance because of items such as loan principal, asset purchases, and owner distributions. Ask your bookkeeper which basis your reports use.

The balance sheet helps explain that gap. Five common sources of differences between profit and available cash are worth reviewing.

1. Accounts receivable: money customers owe you

Receivables tend to grow in step with sales. If customers pay you in 45 days on average, roughly a month and a half of revenue may be tied up in unpaid invoices. For a $3M business, that is about $370,000, assuming sales are relatively steady.

Here is the part that often gets overlooked: when sales grow, receivables grow with them. A business that grows 20% in a year will typically have 20% more cash tied up in receivables, even if every customer pays on time. Growth consumes cash before it produces it.

The opportunity works the other way, too. Reducing average collection time from 45 days to 30 days in that same $3M business frees up roughly $120,000 in cash, without a single new sale.

2. Inventory and job materials

When you buy materials ahead of a job or stock up before a busy season, accounting treats that purchase as an asset, not an expense. It doesn't hit the P&L until the materials are used or sold. Your profit looks healthy while your checking account carries the cost.

Slow-moving or excess inventory is a quiet drain. Every dollar on a shelf is a dollar that can't be used for payroll, debt, or opportunities.

3. Loan principal payments

Only the interest portion of a loan payment appears as an expense on the P&L. The principal portion, which is often the larger share, reduces the loan balance on the balance sheet instead. An owner with a truck loan, an equipment note, and a line of credit can easily be paying several thousand dollars a month that never shows up on the profit report.

4. Owner distributions and income taxes

S corporations and many LLCs are taxed as pass-through entities, although an LLC's tax treatment depends on its elections and ownership. Owners may owe tax on business income even when the cash stays in the business. Distributions reduce available business cash without being operating expenses. Your CPA should determine the tax estimates, timing, and appropriate way to fund them; cash planning should reflect that guidance.

5. Investment in growth

New hires, a second location, additional vehicles, or a larger facility usually require cash months before they generate revenue. This is healthy, but it needs to be planned. Growth that outpaces available cash is one of the most common reasons otherwise strong businesses run into trouble.

How to manage the gap

• Review your balance sheet every month alongside your P&L. Watch the trend in receivables, inventory, and debt balances.
• Track days sales outstanding (DSO), an estimate of collection time: average receivables divided by credit sales for the same period, multiplied by the days in that period. Exclude cash sales and consider seasonality; compare the trend alongside your overdue-invoice report.
• Build a 13-week cash forecast. It's a simple, rolling projection of cash in and cash out, week by week. It helps you anticipate cash needs and reduce surprises.
• Set aside tax money in a separate account as profit is earned, based on guidance from your CPA.
• Tighten payment terms, invoice promptly, and require deposits or progress billing on large jobs.
• Plan major purchases and hires against the forecast, not against last month's profit.

The bottom line

Profit tells you whether the business model works. Cash tells you whether you can keep operating while it does. Both matter, and neither one is complete without the other. The good news is that managing cash doesn't require new software or a finance team. It requires looking at the numbers you already have with a clear framework, on a consistent schedule.
