What a Commission Structure Is
A commission structure is the set of rules that determines how much variable pay a sales rep earns on each deal, defined by the commission rate and how that rate moves with revenue closed or quota attainment. It is the mechanism behind a rep's on-target earnings, and it does more than control cost. The structure tells reps which deals are worth chasing and when to close them. Change the structure and behavior changes with it.Flat, tiered, and accelerator structures compared
| Structure | How the rate works | What it rewards |
|---|---|---|
| Flat | One rate on every dollar of revenue, say 10% on all closed business. | Steady volume and simplicity. |
| Tiered | The rate steps up as the rep clears attainment bands, for example 8% up to quota and 10% above it. | Clearing the next threshold. |
| Accelerator | A multiplier applies to revenue closed over quota, often 1.5x to 2x the base rate past 100% attainment. | Overachievement and keeping top reps. |
The behavior each structure rewards
Flat commission rewards consistent output. Every deal pays the same, so a rep has no reason to sprint in the last week of the quarter or to hold a deal back. It fits transactional, high-volume motions where the goal is throughput.
Tiered commission rewards pushing past each band, but it also invites sandbagging. A rep who has already cleared a tier may park the next deal in the following period to start that quarter closer to a higher rate. Deals bunch at the edges of the bands.
Accelerators reward overachievement, and they pull future revenue into the present. Once a rep passes 100% quota attainment, every extra dollar is worth more, so reps chase late-quarter deals hard and sometimes discount to pull a future-quarter deal forward. That protects the current number and thins the next quarter.
How commission design shows up in your forecast
Behavior that a plan pays for becomes a pattern in the pipeline. Accelerators concentrate closes in the final weeks and can inflate a single quarter. Tiered plans push close dates as reps time deals into the band they want. A forecast that ignores comp design reads these patterns as random risk or as strength. Reading them correctly means knowing what your reps are paid to do, then checking whether the attainment distribution matches the structure you set.
Frequently Asked Questions
What is the difference between flat and tiered commission?
A flat structure pays one rate on every dollar of revenue, so the hundredth deal earns the same rate as the first. A tiered structure raises the rate as the rep clears attainment bands, for example 8% up to quota and 10% above it. Flat rewards steady volume. Tiered rewards clearing the next threshold.
What is a commission accelerator?
An accelerator is a higher multiplier applied to revenue a rep closes above quota, often 1.5x to 2x the base rate past 100% attainment. It exists to stretch and retain top performers. The tradeoff is that accelerators reward pulling future deals into the current quarter, which can thin the following one.
Which commission structure is best for a B2B SaaS team?
It follows the sales motion. High-volume transactional teams run well on flat or lightly tiered plans that reward throughput. Enterprise teams, where overachievement is rare and valuable, get more from accelerators. Set the structure to the behavior you want, then confirm quotas are high enough that accelerators pay for real overperformance.
How does commission structure affect revenue forecasting?
Reps close deals in the pattern their plan pays for. Accelerators bunch closes at quarter-end and can inflate one period at the expense of the next. Tiered plans encourage sandbagging and close-date pushing. A forecast should account for these patterns rather than treat them as noise, because comp design drives when and how deals land.
