There are several types of sales quotas that can be used including sales volume, dollar sales volume, unit sales volume, and point sales quotas. Sales volume quotas are the most common and communicate a sales target for a given time period. Budget quotas can also be used to set targets for expenses, gross margins, or net profits. Combination quotas control both selling and non-selling activities by combining different performance metrics into a single measure. When establishing a quota system, management must ensure quotas are accurate, fair, attainable, and accepted by the sales force.
