We Tore Apart a Comp Plan That Paid Reps More to Discount Than to Hold the Line
A line-by-line teardown of an accelerator structure that made a 20%-discounted deal more lucrative for the rep than a full-price one — and the two-line fix that closed the gap.
The exec team's read on this one was simple: margins had eroded two points in a quarter, and the reps had gone soft in negotiation, discounting to close instead of holding the line. That's a story about people. The comp plan I was handed to review told a different story — one about arithmetic — and once you follow the arithmetic through, the reps weren't the ones making the irrational choice. The plan was.
The plan as written
Strip out the boilerplate and the mechanism was this: base commission of 8% on booked revenue up to 100% of quota. Cross 100% attainment for the quarter and an accelerator kicks in — 12% — applied retroactively to every pound booked that quarter, not just the marginal revenue above the line. Cross 120% and the rate jumps again, to 16%, again retroactive. This is an extremely common structure, sold to leadership as a way to reward big quarters disproportionately. It's also a cliff, and cliffs change behaviour in a specific, predictable way: whatever gets you over the cliff sooner is worth far more than its face value, because it doesn't just earn its own commission — it re-rates every deal that came before it in the period.
Nothing in the plan referenced margin. The accelerator tier, the base rate, the whole calculation ran off gross booked revenue. That omission is the entire story.
The maths that exonerated the reps
Take a rep sitting at £460k booked against a £500k quarterly quota with two weeks left — 92% attainment, £40k short of the cliff. Two deals are live:
- Deal A: same buyer, £60k at list price, but procurement wants three more weeks of security review. Realistically slips to next quarter.
- Deal B: same buyer, same need, £48k after a 20% discount. The discount removes the last objection and the buyer signs this week.
Close Deal B and the quarter finishes at £508k — 101.6% attainment, over the cliff. The 12% rate applies to the full £508k: £60,960 in commission. Don't close it, or wait for Deal A next quarter, and the quarter finishes at £460k — under the cliff, base rate only: 8% of £460k, £36,800.
Now compare Deal B against what closing Deal A at full price would have paid, hypothetically, in the same window: £520k total, still over the cliff, 12% of £520k = £62,400. The gap between taking the full-price deal and taking the 20%-discounted one is £1,440 in commission to the rep. The gap in margin given away by the company is £12,000. The rep's personal cost of discounting, once you account for how the accelerator actually calculates, is a rounding error next to the certainty of clearing the cliff this quarter instead of risking a flat £36,800 quarter with the £60k deal now sitting in a pipeline that might not survive procurement's security review at all.
| Scenario | Booked revenue | Attainment | Rate applied | Commission |
|---|---|---|---|---|
| No deal closes this quarter | £460k | 92% | 8% (no accelerator) | £36,800 |
| Deal B closes (20% discount) | £508k | 101.6% | 12%, retroactive | £60,960 |
| Deal A closes hypothetically at list | £520k | 104% | 12%, retroactive | £62,400 |
Read that table as a rep would read it under deadline pressure: discounting cost £1,440 against the full-price outcome, and not discounting risked £24,160 against the do-nothing outcome. There is no version of that choice where holding the line is the rational move, and no amount of sales-skills coaching changes the arithmetic sitting underneath it.
Why the exec team blamed the wrong thing
"Aggressive negotiating" is a comfortable diagnosis because it points at behaviour that training can supposedly fix. It also happened to be wrong, because the actual driver was structural: a revenue-weighted, retroactive accelerator with no margin gate makes the marginal cost of a discount nearly invisible to the person deciding whether to offer one, while making the marginal value of crossing the attainment cliff enormous. Blame the reps and you run a negotiation workshop that changes nothing, because the plan is still telling every rep near a cliff that discounting is nearly free.
The two-line fix
Nobody needed to rebuild the plan. It needed two additions:
- Margin-weight the revenue that counts toward accelerator thresholds. Attainment for tier purposes = booked revenue × (deal margin ÷ target margin), capped at 1.0. Base commission can still be paid on gross revenue if the org wants simplicity there — but the number that decides whether you've crossed the cliff has to reflect what the deal actually protected, not what it billed.
- Discounts beyond standing authority require Deal Desk approval to count toward accelerator-eligible revenue at all. Unapproved, under-margin deals still count toward quota at base rate — nobody's stopping the rep from closing the business — they just stop being fuel for the cliff.
Run Deal B back through the fixed plan. Target margin was 45%; the 20% discount took it to roughly 30%. Margin ratio: 30 ÷ 45 = 0.667. Margin-adjusted contribution from Deal B: £48k × 0.667 ≈ £32k. Total margin-adjusted attainment: £460k + £32k = £492k against a £500k quota — 98.4%, under the cliff. Base commission is still paid on the full gross £508k at 8% (£40,640), but the 12% accelerator never triggers. The company keeps roughly £20,000 of the commission it would otherwise have paid for a deal that cost it £12,000 in margin to close — and, more importantly, the rep chasing the cliff next quarter now has a real incentive to protect margin rather than revenue, because margin is what the plan is actually paying for.
What this teardown is actually about
A comp plan is a set of instructions written in the only language a revenue org fully trusts: money. Reps followed the instructions perfectly. The instructions just weren't the ones the exec team thought they'd written. Before you run a negotiation-skills intervention on a discounting problem, run the Discount Leakage Calculator against last quarter's booked deals and see whether the pattern clusters suspiciously around attainment thresholds — it usually does, and it's visible in an afternoon. If you're a rep or manager trying to understand what your own plan actually rewards rather than what the summary slide claims it rewards, the Commission Statement Decoder is built for exactly this kind of line-by-line reconstruction.
Fix the plan and the "aggressive negotiating culture" tends to resolve itself within a quarter, without a single workshop. That should tell you something about how much of it was ever a skills problem to begin with.
