Mastering Cash Flow: Understanding Your Real Numbers

Growing up in a family business here in the Midwest, I learned a hard lesson early on: you can have a line of customers out the door and still be kept awake at night wondering how you’re going to cover payroll.

I remember a year when my parents’ shop was busier than ever. Revenue was at an all-time high. But because we hadn’t mastered the “ebb and flow” of our cash, we hit a winter wall. We had tied up all our capital in inventory and new equipment during the summer rush, leaving the bank account bone-dry when the snow started to fall and the foot traffic slowed.

As the Northern Regional Director of the Michigan SBDC, I see this every day. Profitability is great, but cash flow is what keeps the lights on. If you want to move from just “surviving” to truly growing, you have to look past the sales numbers and start managing the movement of your money.

Here is how you can master your cash flow to control your inventory, make smarter investments, and find financial success.

1. Separate Your Worlds

The quickest way to lose track of your business health is to mix it with your personal life. From day one, you must have a dedicated business checking account and credit card. This isn’t just for clean taxes; it’s about having a clear, unfiltered view of what your business is actually doing.

2. Make Your Data Bulletproof

Whether you use QuickBooks® or another system, your bookkeeping must be precise. A golden rule we advocate for at the Michigan SBDC: your total sales must match your total deposits. Never spend cash from a sale before it hits the bank. If you can’t trust your data, you can’t trust your decisions.

3. Find Your “Survival Number”

Every owner should know their Target Revenue. This is the total dollar amount you need to bring in every month to cover your costs.

To find yours, use this formula:

Your Gross Profit Margin Percentage represents what is left from every dollar of sales after you pay for the direct cost of providing that service or product.

To find yours, use this formula:

Knowing this number allows you to see exactly when you’re actually making money and when you’re just “trading dollars.”

4. Use Projections as Your GPS

A Profit and Loss statement tells you what happened last month. A Cash Flow Projection tells you what will happen next month. This is the secret weapon for Michigan’s seasonal businesses. By mapping out your year, you can see that “winter dip” coming from months away and adjust your inventory purchases or equipment investments accordingly.

5. Sales Pay the Business First

It’s a tough pill to swallow, but as the owner, you get paid last. Sales must cover business expenses and future reserves first. Only when the business is healthy and the bills are paid should you take a systematic owner’s draw.
