I’ve seen profitable businesses run out of cash. It sounds contradictory until you understand the timing gap between when work is done and when money actually arrives in the account.
In commercial work, that gap can be 30, 60, or 90 days depending on the client and contract structure. If you’re paying employees and suppliers in real time while waiting for receivables to clear, the math gets uncomfortable fast.
The difference between profit and cash
Your P&L shows whether you’re making money. Your bank account shows whether you can pay your bills today. These are two different numbers and they’re often significantly different.
A business can show strong monthly revenue on paper and still bounce payroll if the receivables don’t collect on schedule. Understanding this distinction early is one of the most important things a business owner can do.
Practical cash flow management
Know your cash cycle — from the day work begins to the day payment clears, how many days does it typically take? Map this for your five largest client types. The number will probably surprise you.
Invoice immediately when work is completed or at defined milestones. Every day you delay invoicing is a day you add to the cash gap for no reason.
Follow up on outstanding invoices before they’re overdue, not after. A quick call or email at day 25 on a net-30 invoice is professional and effective. Waiting until day 45 and then chasing it is harder for everyone.
Build a cash reserve that covers at least 60 days of fixed operating expenses. This isn’t an emergency fund — it’s an operating buffer that gives you room to manage timing gaps without stress.
On QuickBooks and your books
If your accounting software doesn’t have current numbers, you’re flying without instruments. Reconcile weekly. Run your accounts receivable aging report every Monday morning. If an invoice is past due, you address it that day — not when you notice a problem with the bank balance.
The businesses that stay healthy financially are almost always the ones with clean, current books. It’s not exciting work. It’s foundational work.
When to bring in help
If accounting isn’t your strength, hire a bookkeeper before you need one, not after. A part-time bookkeeper who keeps your records current and your receivables tracked is one of the highest-return hires a small business can make.
Your time is better spent on revenue-generating activities than on sorting through receipts. Know when to delegate.
