Sales Are Growing but Cash Is Tight: A DFW Owner's Working Capital Guide

It is one of the most counterintuitive moments an owner faces: sales are up, the team is busy, the P&L shows a profit — and the bank balance keeps shrinking. Growth is supposed to feel like winning. Instead it feels like drowning.

This isn't a paradox; it's working capital. Growth consumes cash before it produces it, and the faster you grow, the wider that gap gets. In a market where the Federal Reserve's small-business research shows operating expenses are the top reason firms seek financing, understanding this gap is one of the highest-leverage things an owner can learn.

Why profitable businesses run out of cash

Profit is an accounting measure; cash is a timing reality. You recognize revenue when you invoice, but you collect weeks later. You pay your team, your vendors, your lender, and your tax reserve on their schedule, not your customers'. The bigger the order, the longer the project, the more inventory you carry — the more cash is locked up between 'we earned it' and 'we have it.'

Growth amplifies every piece of this at once. More sales mean more receivables, more inventory or work-in-progress, more payroll funded before collection. That is why a profitable, fast-growing company can be the one most likely to hit a cash wall.

AR days and collection discipline

Accounts receivable is usually the biggest lever. Track your average collection period (AR days) and watch the trend, not just the snapshot. Tighten terms where the market allows, invoice the day work is complete, automate reminders, and follow up on past-due balances on a schedule rather than when you happen to notice.

Cutting AR days from 60 to 40 on a business with $2M in annual sales frees roughly $110,000 of cash — without a single new customer.

AP timing, inventory, and project costs

Accounts payable is the other side of the lever. Negotiate vendor terms that match your collection cycle, take early-pay discounts only when the math beats your cost of capital, and avoid paying everything the moment the bill arrives out of habit.

For product businesses, inventory is trapped cash — track turns and carrying cost. For project businesses, unbilled work-in-progress is the same problem in a different shape: bill promptly against milestones so you aren't financing your customers' projects out of your own operating account.

Debt service and tax reserves

Two outflows quietly wreck cash plans because they don't show up on the P&L the way they hit the bank: loan principal and taxes. Principal repayment reduces a liability — it isn't an expense — so a profitable business can still be cash-negative after debt service. And tax reserves must be set aside as you earn, not scrambled for at deadline.

Build both into your forecast explicitly. A simple rule: every month, move the estimated tax reserve and the upcoming principal into a 'do not touch' view so you never confuse it with spendable cash.

Build a working-capital dashboard

Pull these into one weekly view: cash on hand, AR aging and AR days, AP aging, inventory or WIP balance, upcoming payroll, debt service due, and the tax reserve. Add a rolling 13-week cash projection so you can see the gap before it arrives — our 13-week cash flow forecast guide walks through the exact structure.

The dashboard turns 'how are we doing on cash?' from a gut feeling into a number you check every Monday in fifteen minutes.

Secure a line of credit before you need it

The cheapest time to arrange a line of credit is when you don't need it — when the books are clean, the trend is up, and you have leverage. The most expensive time is when cash is already tight and the lender can see it.

If growth is on your horizon, treat a revolving line as infrastructure, not a rescue. It smooths the working-capital gap so a great quarter doesn't become a cash crisis. This is exactly the kind of decision a fractional CFO helps you get ahead of.
