Cheers ☕️. Most founders learn profit first.
Then they learn the hard way that profit and cash are not the same thing.
Net working capital is the space between them. It is where growth quietly eats cash, where “good months” still feel tight, and where simple operational fixes can unlock real breathing room.
Local note: Fuse supports founders in Charlotte, North Carolina and beyond. Some of the best progress still happens face to face over coffee, with a clean balance sheet and an AR aging report on the table.
Net working capital is the cash your business needs to run day to day while you wait for money to come in.
If your customers pay you later, you fund that gap.
If you buy inventory before you sell it, you fund that gap.
If you pay vendors faster than customers pay you, you fund that gap.
That is why two companies with the same profit can have completely different cash stress.
At the simplest level:
Net Working Capital (NWC) = Current Assets − Current Liabilities
In most founder-run businesses, the working part of working capital is usually driven by three lines:
Here is the key idea:
When net working capital goes up, cash usually goes down.
Why? Because you are tying up more money in receivables and inventory, and you are paying bills faster than you need to.
If you want one mental model that makes net working capital feel real, use this:
Cash Conversion Cycle (CCC) = DSO + DIO − DPO
Shorter CCC usually means less cash trapped in the business.
Longer CCC usually means more cash trapped in the business.
Founders feel this as stress. Finance people see it as a timing problem.
You do not need to become a spreadsheet wizard to improve working capital. You need a few consistent moves and a weekly rhythm.
Here are the patterns we see when net working capital is the real problem:
Here is a simple example of how this happens:
Nothing “mystical” happened. Timing happened.
Progress comes from rhythm. Here is a practical sprint we run with founders.
Founders do not need fifty KPIs. They need the few that control cash.

It depends on your model. The more important question is trend and control. Are you shortening your cash cycle over time, and do you understand what is driving it?
Yes. Some businesses collect cash fast and pay vendors later. That can be a strength. It becomes a problem when it is driven by missed bills, unclear processes, or vendor strain.
Start with AR aging, DSO trend, inventory levels for key SKUs, and a simple view of upcoming AP payments. Keep it tight, keep it consistent.
Growth often expands AR and inventory faster than cash arrives. If customer terms are loose and collections are inconsistent, revenue growth can create a cash crunch.
Clear terms and consistent invoicing usually improve relationships. Surprises and last-minute pressure are what damage trust. Set expectations early and deliver clean communication.
Working capital is not “finance trivia.” It is operational reality.
When you can see the timing, you can control the timing.
