Cash conversion and DSO: why revenue is not cash
You can have a record quarter and an empty bank account at the same time. Revenue is what you book. Cash is what arrives. The distance between them has a name, and most commercial leaders never look at it.

The gap between revenue and cash
Revenue is booked when you deliver. Cash arrives when the customer pays. In B2B with enterprise buyers, public-sector customers, or channel partners, the gap between those two moments is routinely 60 to 120 days, sometimes longer. That gap is not a rounding error. It is the difference between a business that can fund its own growth and one that runs out of room right when it should be accelerating.
The gap shows up on the balance sheet as accounts receivable, which sits inside the Asset Efficiency driver of the Enterprise Value Map. It is one of the boxes commercial teams skip entirely, because it feels like a finance problem. It is not. It is created by commercial decisions.
What DSO is and how to read it
Days Sales Outstanding is the average number of days it takes to collect cash after a sale. A DSO of 75 means that, on average, money sits unpaid for 75 days after you have earned it. The number itself matters less than two things: the trend and the spread.
- The trend. A DSO drifting up means collections are slowing relative to sales. It is an early warning that often shows up before any cash crunch does.
- The spread. Blended DSO hides the story. One channel or segment paying in 30 days and another in 120 averages to something that describes neither. Track DSO by channel and by customer segment, not just company-wide.
The cash conversion cycle
DSO is one piece of a bigger picture. The cash conversion cycle is how long your money is tied up from the moment you spend it to the moment the customer pays you back. For a product business it includes inventory sitting on the shelf and the terms you get from your own suppliers. The shorter the cycle, the more your business funds itself. The longer it is, the more you depend on outside capital just to keep operating at the same size.
Why comp and terms drive it
Here is the part that makes this a commercial problem. When the comp plan pays on bookings, reps grant extended payment terms freely, because their commission lands the moment the deal closes. The receivable, and the cash problem it creates, lands months later on the finance team. The rep was rational. The plan made the trade for them.
This is why the fix is partly a compensation design question. Tie a portion of commission to collected revenue, not just booked revenue, and the person closing the deal suddenly cares whether the customer actually pays.
How to improve it
- Put DSO on the commercial agenda. Not just the finance report. What commercial leadership reviews is what changes.
- Tie comp to collected cash. The single highest-return change for aligning sales behavior with cash reality.
- Standardize terms and make exceptions visible. Extended terms should be a deliberate concession with a cost attached, not a default a rep gives away to close faster.
- Invoice fast and follow up faster. A surprising amount of DSO is self-inflicted through slow invoicing and passive collections, not customer behavior.
Frequently asked questions
What is Days Sales Outstanding (DSO)?
Days Sales Outstanding is the average number of days it takes to collect cash after a sale. A DSO of 75 means money sits unpaid for an average of 75 days after the revenue is earned. The trend and the spread by channel matter more than the headline number.
Why is revenue not the same as cash?
Revenue is recognized when you deliver. Cash arrives only when the customer pays, which with enterprise, public-sector, or channel buyers can run 60 to 120 days later (median B2B DSO is closer to 50 to 60 days). That gap appears on the balance sheet as accounts receivable, and it determines whether a business can fund its own growth.
What is the cash conversion cycle?
The cash conversion cycle is how long your money is tied up from when you spend it to when the customer pays you back, including inventory and supplier terms. A shorter cycle means the business funds itself; a longer one means it depends on outside capital to operate at the same size.
How do you improve DSO and cash conversion?
Put DSO on the commercial agenda by channel and segment, tie part of sales commission to collected revenue rather than bookings, standardize payment terms and price exceptions deliberately, and invoice and follow up faster. Much of high DSO is self-inflicted through slow process, not customer behavior.
