Why Growing Businesses Run Out of Cash
My business does $10 million a year but I have no cash. That sentence is more common than it should be, and it is almost never a mystery once you look at the calendar instead of the year-to-date P&L.

Why does a profitable company run out of cash?
A profitable company runs out of cash when it funds growth from working capital: customers pay slowly, inventory or work-in-process rises, and the company pays its people and vendors on a faster cycle than it collects. The P&L can look fine while the checking account does not.
Cash is a timing problem wearing an accounting costume. Growth makes the timing worse, because the company must buy, hire, and deliver before the customer pays.
The cash conversion cycle
Money leaves for labor, materials, and overhead. Money returns when the customer pays. The gap is funded by someone: the owner, a lender, or unpaid vendors. Growing the top line lengthens the gap unless collections, inventory, and terms improve at the same time.
The usual culprits
- Receivables that grow faster than sales, often because the owner will not pressure a familiar customer.
- Inventory or jobs that sit, because saying no to work feels like leaving money on the table.
- Vendor terms that are tighter than customer terms.
- Tax, distributions, or owner compensation that assume last year's cash pattern still holds.
- A 'profitable' job that was bid without the cost of carrying it.
What to do in the first thirty days
Build a thirteen-week cash view. Collect the old invoices with a named owner. Stop bidding work that consumes cash you do not have. Match purchasing to demand. That is how a company stays solvent enough to be improved.
Longer term, cash discipline is part of financial performance and part of operations. Companies that cannot see cash weekly cannot manage anything else with confidence.
Profit on paper is not the same as cash in the account.
