Sales commission is a variable payment earned when a sales-related outcome is achieved. That outcome could be a closed-won deal, new recurring revenue, a booked contract, a qualified opportunity, expansion revenue, margin contribution, or quota attainment.
Companies use commissions because they create a direct link between sales behavior and business results. When the rules are clear, commission plans help focus sellers on the outcomes that matter most, such as winning new business, protecting margin, expanding accounts, or improving deal quality.
A sales commission plan should explain who is eligible, what is rewarded, which data is used, how the payout is calculated, when it is reviewed, and when it is paid. Without that clarity, commissions can create disputes instead of motivation.
Sales commission is one type of incentive compensation, alongside bonuses, SPIFs, OTE-based plans, KPI incentives, and other forms of variable pay. That matters because commission rules rarely live in isolation. They affect forecasting, Finance review, HR communication, sales behavior, and GTM performance.
How commission differs from salary, bonus, SPIF, and OTE
-
Salary is fixed pay. It does not usually change based on deal outcomes.
-
Commission is variable pay tied to measurable sales outcomes, often a percentage of eligible revenue, bookings, or margin.
-
Bonus is usually a periodic or lump-sum reward tied to individual, team, or company performance.
-
SPIF is a short-term incentive used to drive a specific action, such as selling a new product or accelerating quarter-end activity.
-
OTE stands for on-target earnings. It represents total expected pay when a role hits 100% of its goals, including base salary and target variable pay.
In other words, sales compensation is the full pay system for sales roles. Commission is one important part of that system.
