Commission is a wonderful motivator right up until someone disagrees about how much they earned. Was that sale really theirs? Does the commission come off the total or the profit? What happens if the customer cancels next month? These questions cause more friction in sales teams than almost anything else, and they all have the same fix: a clear commission agreement written before the selling starts. Here is what one should cover so everyone gets paid fairly and nobody ends up arguing.
What a commission agreement is
A commission agreement is a contract that sets out how commission will be earned and paid. It applies whenever someone is paid based on the sales or results they generate, whether they are an employee, a freelancer, a sales rep or an affiliate. The agreement defines what triggers a commission, how it is calculated, when it is paid, and what happens in the awkward situations that inevitably come up. It turns "we will sort out the details later" into something both sides can rely on.
What it should cover
A solid commission agreement answers the questions that cause disputes:
- The commission rate: a percentage, a flat amount, or a tiered structure.
- The basis: whether commission is on total sales, profit, or something else.
- When commission is earned: at the sale, at payment, or at delivery.
- When it is paid: the schedule for actually receiving it.
- What happens on refunds, cancellations or non-payment.
- How disputed or shared sales are handled.
Define exactly when commission is earned
This is the single most important clause, and the one most often left vague. There is a big difference between commission earned when a deal is signed and commission earned when the customer actually pays. If your agreement pays on signing, you can end up paying commission on a sale that later falls through. If it pays on receipt of payment, the salesperson carries some of the risk of a customer who does not pay. Neither is wrong, but you must choose deliberately and write it down, because this is precisely where trust breaks down. A clear rule, applied consistently, keeps everyone confident that the numbers are fair.
Plan for refunds and clawbacks
What happens when a customer returns the goods or cancels the service after commission has been paid? If your agreement is silent on this, you are in for an uncomfortable conversation. Many commission structures include a clawback provision, where commission paid on a sale that is later refunded or cancelled is deducted from future commission. It feels harsh, but without it, a business ends up paying for sales that never really happened. The key is to make the rule clear from the start, so a salesperson knows a commission is not truly theirs until the sale is genuinely complete. Spelled out in advance, a clawback is fair; sprung as a surprise, it feels like a betrayal.
Keep it motivating and transparent
A commission agreement is not just a legal safeguard; it is a motivation tool, so design it to encourage the behaviour you actually want. If you want bigger deals, weight the commission toward them. If you want retention, tie some commission to customers who stay. Above all, keep the calculation transparent enough that a salesperson can work out their own commission and check it. Nothing kills motivation faster than a commission scheme so complicated that people cannot tell whether they are being paid correctly. A fair, clear, motivating agreement turns commission from a source of arguments into exactly what it is meant to be: a reward that drives the results you are after.
Frequently asked questions
When is commission usually earned?
It depends on the agreement. Common triggers are when a deal is signed, when the customer pays, or when goods are delivered. The agreement should state which clearly.
What is a commission clawback?
It is a provision that recovers commission already paid on a sale that is later refunded or cancelled, usually by deducting it from future commission.
Should commission be on total sales or profit?
Either can work. Commission on profit protects your margins; commission on total sales is simpler. Choose deliberately and state it clearly.
Do freelancers and affiliates need commission agreements too?
Yes. Anyone paid based on results benefits from a clear agreement covering rate, timing and what happens with refunds or disputes.
How do you handle a sale that two people worked on?
Decide the rule in advance: a split, a credit to whoever closed it, or a shared percentage. Shared and disputed deals cause the most friction, so a clear policy written into the agreement prevents arguments before they start, and everyone knows how the credit will be divided long before a big deal comes in.
