I've spent a lot of words on expansion revenue costing a fraction of what new-logo revenue costs. It's true and I'd defend the arithmetic. But the emphasis is wrong, and a sales leader pushed on it this week in a way that made me see it.
"Cheaper" makes it sound like the point is to spend less on the most valuable revenue in the business.
That's not the point. Run the number the other way and it says something better.
What You're Actually Paying
New-logo revenue costs what you paid to acquire it. For a top-quartile company that's about 50 cents on the dollar of first-year contract value. The industry median is a twelve-month payback, which means a full dollar of cost for a dollar of first-order revenue. Enterprise runs longer than that.
Expansion revenue costs a commission. Usually about 10 percent, often less, because there's no campaign behind it, no SDR, no pipeline, and no discovery on a stranger.
That's the five-to-ten-times comparison, and it's the one I've been making.
Now Run It Backwards
Stop asking what expansion costs. Ask what you could afford to pay for it.
Double the commission to 20 percent and you're still five times cheaper than a median CAC. Triple it to 30 and you're still ahead by more than three times. Pay 50 percent, the same as a top-quartile company pays to acquire a customer cold, and you've reached break-even on cost while still winning on every other number: faster payback, higher NRR, more LTV per account.
There is an enormous amount of room in there. The industry has settled on 10 percent because that's what it settled on, not because that's what the revenue is worth.
Why This Matters More Than The Discount
I've written before that expansion is the only revenue motion with no loss attached to it, which is why nothing in the organization fights for it. Sales quota runs on loss aversion. Churn runs on loss aversion. Nobody has ever been fired for missing revenue nobody measured.
A 10 percent commission on a number nobody tracks is not a reason for anyone to change what they do on Monday. It's a rounding error attached to an invisible goal.
The headroom is the answer to that. You can attach a number worth chasing, pay it out of margin that acquisition would have consumed anyway, and still be several times better off than sourcing the same dollar cold. Who it gets paid to is a separate question, and a harder one.
The Objection
Somebody will say this destroys margin. It doesn't, and the comparison is the reason.
You're not comparing a 30 percent commission against zero. You're comparing it against what you already pay for the same dollar of revenue when it arrives from a stranger. Against that, 30 percent is a bargain you'd take every time. The only reason it looks expensive is that expansion currently costs so little that anything above a rounding error feels like a splurge.
Cheap is not the achievement. Cheap was never the goal anywhere else either. Cheap is the symptom of nobody trying.
What To Do With This
Look at what you pay for a dollar of new revenue and what you pay for a dollar of expansion revenue. Not what you budget. What you actually pay, per dollar, all in.
Then ask whether the gap between those two numbers is a competitive advantage you're banking or a signal that nobody in your company has been given a reason to go get the second one.
Most of the time it's the second, and the fix isn't a better playbook. It's a number on somebody's comp plan large enough that they'd reorganize their week for it.
