What it means
At its simplest, commission is a rate applied to a base. A salesperson on 5% of invoiced revenue earns $5,000 on $100,000 of sales, and nothing if nothing sells.
Brokers, estate agents, recruiters and payment processors all charge commission in the same structural way, just with different bases. Commission matters to a business because it converts a fixed cost into a variable one.
A team paid mostly on commission costs less when revenue is weak, which protects cash flow in a downturn. The trade-off is that high-performing people expect uncapped upside, so a good year can produce pay packets that surprise a board that only modelled the average.
The mechanics are where most disputes arise. A scheme has to define the base, whether that is booked revenue, invoiced revenue, cash collected or gross margin, and it has to state when commission is earned and when it is clawed back if the customer cancels or fails to pay.
Paying on booked revenue with no clawback is the classic way to end up rewarding sales that never turn into cash. Most schemes are tiered rather than flat.
A rep might earn a lower rate up to quota and an accelerated rate above it, which pushes effort towards the end of the period rather than spreading it evenly. Accelerators are deliberate, but they can also encourage deals to be pulled forward or pushed into the next quarter, so finance teams watch period-end patterns closely.
The nuance worth remembering is that people optimise for whatever the scheme measures. Commission on revenue encourages discounting, because a discounted deal still pays; Commission on gross margin removes that incentive but is harder to explain and depends on cost data the rep may not trust.
The right base is the one that matches what the business actually needs more of.
In practice
Real-world examples
Example 1
A commercial insurance broker is paid 12% of the first-year premium on every policy placed. On an $85,000 policy that is $10,200, received when the insurer pays the broking house. The broker's own bonus is calculated on renewals, so the firm keeps an incentive to service the account rather than just win it.
Example 2
A software company changes its scheme from 6% of contract value to 10% of first-year gross margin. Discounting drops sharply in the following two quarters because a 20% price cut now cuts commission far more than it used to. Average deal size falls slightly, but realised margin per deal improves.
Example 3
An estate agency charges a seller 1.4% of the sale price. On a $640,000 property that is $8,960, payable on completion rather than on offer acceptance. The agency pays its negotiator 15% of that fee, or $1,344, once the money is received.
Think of it
Think of a commission like a tip you give to a waiter at a restaurant. Just as you might tip more for excellent service, a commission rewards someone for successfully completing a task, like making a sale.
Formula
Calculation
Commission earned = (eligible sales at each tier x that tier's rate), summed across tiers
A sales representative has a quarterly quota of $300,000 and closes $420,000 of invoiced revenue. The scheme pays 5% on everything up to quota and an accelerated 8% on revenue above quota.
Base tier = $300,000 x 5% = $15,000
Accelerator tier = ($420,000 - $300,000) x 8% = $120,000 x 8% = $9,600
Total commission = $15,000 + $9,600 = $24,600
As a blended rate that is $24,600 / $420,000 = 5.86% of revenue. If the same rep had closed only $300,000, commission would have been $15,000, so the last $120,000 of sales was worth $9,600 to the rep and paid at a materially higher rate than the first tranche.Case study
Seen in the real world
Braxley Industrial Supplies is a fictional, illustrative distributor with 14 field sales staff and revenue of $22,000,000. Its long-standing scheme paid a flat 4% of invoiced revenue with no reference to margin, and management could not understand why gross margin had slipped from 31% to 26% over three years while volumes grew.
The pattern was straightforward once the data was cut by rep. Discounting had crept up because a rep giving away 5% of price lost only 5% of their commission but the company lost about a sixth of its margin on that order. The scheme was rewarding volume at any price.
Braxley moved to a scheme paying 12% of gross margin dollars, with a transitional guarantee for two quarters so nobody's earnings collapsed while they adjusted. In this illustrative outcome, revenue growth slowed but gross margin recovered to 30% within a year, and total commission paid stayed almost unchanged because the better-margin reps earned more and the discounters earned less.
Watch out
Common mistakes
- Paying commission on booked orders with no clawback, so the company pays out on deals that are later cancelled or never collected.
- Changing scheme rules mid-period, which destroys trust far faster than a lower rate ever would.
- Assuming a capped scheme saves money, when the usual result is that the best performers stop selling once they hit the cap.
Questions
People also ask
Should commission be paid on revenue or on gross margin?
Margin-based schemes protect pricing and suit distributors and services firms, while revenue-based schemes are simpler and suit businesses with tightly controlled list prices.
When is commission recognised as an expense in the accounts?
It is accrued in the period the related sale is recognised, not the period it is paid, so a quarter-end sale creates a liability even if the cheque goes out weeks later.
Are accelerators worth the extra cost?
Usually yes if quota is set realistically, because the incremental commission is paid only on revenue the company would not otherwise have booked.
