Welcome to Edition 3 of The KAT Edge.
Last edition we took apart CARR: why it is on every board deck and why most companies cannot reconcile it. Before that, we separated the three numbers leadership treats as interchangeable: bookings, billing, and revenue. In that first edition I named a gap and walked past it on purpose. The gap between billing and cash. DSO.
This edition we go there. Not the definition. The dollars.
Let's get into it.
Your DSO is a number your finance team reports and your board nods at. It is also, quietly, one of the largest uninvested assets on your balance sheet.
Days Sales Outstanding measures the average time between sending an invoice and collecting the cash. The formula is simple: accounts receivable divided by revenue, times the number of days in the period. A DSO of 60 means that, on average, every dollar you bill takes two months to arrive.
Here is the part that gets waved away. Every single day of DSO is cash you have already earned, already invoiced, and are financing for free on behalf of your customer.
It is tempting to treat slow cash as a customer-quality issue or a sales-discipline issue. By the time DSO is the problem, the deal is signed and the work is delivered. What is left is process: when the invoice goes out, whether the terms match the contract, whether disputes have an owner and a deadline, whether anyone is actually working the collection.
In Edition 1 I described milestone invoicing that depended on a human remembering to pass the baton between Professional Services and billing. One missed handoff and the billing clock stops, which means the cash clock never starts. That is DSO being manufactured inside your own four walls, with no help from the customer.
What one day of DSO is worth at your ARR.
This is arithmetic, not a benchmark. Cash tied up per day of DSO equals your annualized recurring revenue divided by 365. So the value of pulling your DSO down is fixed and knowable for your exact business.
Read the $50M row. Cutting DSO by 15 days frees roughly $2.05M in cash, permanently, without raising a dollar of new capital or closing a single new deal. The last column is the part finance feels and the board forgets: that freed cash has a carrying cost. At a 12 percent cost of capital, the $50M company is paying about $247K a year to finance receivables it could have collected. The cash-freed columns require no assumptions. Only the carrying cost does. Swap your own cost of capital into that column and it scales linearly. For venture-stage SaaS the real rate is usually higher, which makes the cost of slow cash worse, not better.
Where the days actually hide.
When I pull DSO apart in week one, the days almost never sit where people expect. The usual sources, in order of how often they surprise leadership:
Invoicing lag. The contract is signed and the work is live, but the first invoice goes out two, three, four weeks late. Those weeks are pure DSO and they were created entirely by you.
Terms that do not match the contract. The contract says Net 30. The invoice says Net 45. The customer pays to the longer term. Nobody reconciled the two.
Disputes without an owner. A line item is questioned, the invoice stalls, and there is no name and no date attached to resolving it. It ages quietly.
Collections that nobody runs. Not a dunning email. An actual person, working a prioritized list, before the balance is 90 days old. Each of these is fixable in weeks, not quarters. None of them requires a conversation with sales.
The benchmark that matters.
You will find SaaS DSO benchmarks ranging from the low 30s to the high 60s depending on who is selling the report. Most of that spread is methodology, not insight. The benchmark worth using is your own terms. Your DSO should sit within roughly 10 to 15 days of your stated payment terms. If you bill Net 30 and your DSO is 58, the 28-day gap is not the market. It is process, and the table above tells you exactly what closing it is worth.
What to watch for.
If you want to know whether DSO is quietly financing your customers, ask these four questions:
1. What is the average lag between contract go-live and the first invoice, and who owns shortening it?
2. Do our invoice terms reconcile to the executed contract terms, every time, automatically?
3. Which receivables over 60 days have a named owner and a resolution date, and which do not?
4. If we cut DSO by 15 days, what would that free in cash, and what are we currently paying to carry it?
If question four draws a blank, your finance team is sitting on the answer in the table above and has never run the number for your business.
DSO is not a collections statistic. It is the speed at which your earned revenue becomes spendable cash. Every day you leave on the table is capital you raised the hard way and then lent back to your customers, interest-free.
The cash is already yours. The only question is when it shows up.
Where does DSO hide in your business, and what has actually moved it? I would like to hear what is working in the comments.
