Sales commission is the variable pay a rep earns on the deals they close. Three inputs set the number: the commission rate, the base the rate applies to, and the accelerators that raise the rate once a rep clears quota. The first two decide how much a deal pays. The third decides something forecasting teams care about more, which is when reps try to close it.
Rate, base, and accelerators
Rate is the percentage a rep earns on a deal. A plan might pay 10% on new business. Some plans hold the rate flat across the year. Others tier it, paying a lower rate on early attainment and a higher rate later. Base is the dollar figure the rate multiplies. Common bases are total bookings, annual contract value, total contract value, recognized revenue, or gross margin. The base shapes behavior. Pay on bookings and reps chase logo count and contract length. Pay on margin and reps protect price, because every dollar of discount cuts their own check. Accelerators raise the rate above quota. A rep at 100% attainment earns the base rate, then 1.5x to 2x that rate on every dollar past quota. Accelerators are the strongest timing lever in a comp plan, because they change what a single deal is worth depending on when it lands.How commission mechanics move deal timing
Accelerators and period boundaries pull against each other, and reps respond to both. A rep who has already crossed quota sits in accelerator territory, so every remaining deal pays more this period than next. They pull deals forward, sometimes trading a discount for a signature before the quarter closes. A rep sitting well below quota does the opposite. A deal that will not lift them over quota is worth more next period, when it can count toward a new number and the higher rates that follow. So it gets pushed.
The result is closes that cluster at period end for comp reasons, not demand reasons. ORM's view of forecasting treats this directly. The strongest slippage signal is a rep changing a deal's close date, and a deal that slips one quarter is less likely to close at all. Pull-forward gets modeled as its own revenue source, separate from carry-over pipeline and from deals created and closed inside the quarter, because the discount and the borrowed future deal both carry a cost.
Why this matters for the forecast
A forecast that trusts every close date inherits the comp plan behind it. Reading the quarter correctly means separating deals that close on their own merit from deals timed around a threshold. Commission structure is one of the first places to look when close dates bunch up in the final weeks.
Frequently Asked Questions
What is the difference between commission rate and commission base?
The rate is the percentage a rep earns. The base is the dollar figure it applies to, such as bookings, annual contract value, recognized revenue, or gross margin. A 10% rate on a $50,000 bookings base pays $5,000. Changing the base changes rep behavior even when the rate stays the same.
What are commission accelerators?
Accelerators are higher commission rates that start once a rep passes quota. A plan might pay the base rate up to 100% attainment, then 1.5x to 2x that rate on every dollar above it. Accelerators reward overperformance and are the main reason reps push to close deals before a period ends.
How do commission accelerators affect the forecast?
They concentrate closes at period end. Reps in accelerator territory pull deals forward to earn the higher rate, while reps behind quota let deals slip to the next period. Both are timing choices driven by pay, not by buyer readiness, so a forecast has to separate them from real demand.
What base should a SaaS company pay commission on?
It depends on the behavior you want. A bookings base rewards new contract volume and length. A margin base discourages discounting, because reps feel every price cut in their own check. Recognized revenue sits between them, tying pay to delivery. Most SaaS teams pay on bookings or annual contract value, then use accelerators and clawbacks to correct for the tradeoffs.
