A spiff is a short-term cash incentive paid on top of normal commission for doing something specific: selling a particular product, closing before a date, attaching a service, booking a certain kind of meeting. The term comes from nineteenth-century retail, where it meant a payment to a shop assistant for pushing particular stock. The acronym expansions arrived much later.
How it differs from the things it gets confused with
| Instrument | Paid for | Who can earn it |
|---|---|---|
| Commission | Booked revenue, on a standing rate. | Everyone, continuously. |
| Bonus | Hitting a threshold such as quota or an annual target. | Everyone who clears the bar. |
| Spiff | One named behaviour, inside a window. | Everyone who does the thing, as many times as they do it. |
| Contest | Beating other people. | Usually one winner, which is a different motivational instrument entirely. |
The last row is the one worth separating out. A spiff with an uncapped per-unit payout motivates the whole team. A contest motivates the three people who think they can win and is ignored by everybody else by week two.
The four ways they go wrong
Pull-forward. A quarter-end spiff on closing deals mostly moves deals that were closing anyway. You pay a premium on revenue you already had, and the following quarter starts with an emptier pipeline. The spiff looks like it worked because the measurement window ends before the cost arrives.
Paying twice for the same discount. If the fastest way to earn the spiff is to concede on price, the company funds both sides of the trade: the margin given away and the bonus paid for giving it away. This is close to invisible when concessions are made in terms rather than headline price, which is the gap between list and realised revenue.
Rewarding the already-winning. Spiffs tied to volume go to the sellers with the best territories. The sellers who most need a behaviour change watch the same two names collect, and conclude the scheme is not for them.
Never being switched off. A spiff that runs three quarters in a row is a part of the comp plan that nobody has had to defend in a plan review. It is also no longer motivating anything, because the team has priced it in.
Rules for one that works
One behaviour, stated as an action. Not "sell more of product B" but "close a product B deal with a minimum term of twelve months". Vague targets get interpreted in whatever way is cheapest to reach.
A published end date, honoured. The window is the mechanism. Extending it once teaches everyone that the next deadline is also soft.
A floor on the thing you do not want traded away. If the spiff pays on closing speed, attach a minimum discount threshold or it will be funded out of price.
A control to measure against. Compare the spiffed behaviour to the trend in the two quarters before, and to any segment not covered. Without that, a spiff is judged on whether the number went up in a quarter where several things changed at once, which is not evidence.
Fast payment. A spiff paid two months later in an unexplained line on a statement has lost most of its effect. The connection between the act and the money is the entire mechanism.
Partner spiffs are a different instrument
Paying a partner's sellers directly to favour your product works, which is exactly why it needs care. It is a lever acting on people who do not work for you, inside a relationship that already has a structural tension about who owns which account, and that tension is not a relationship problem to begin with. A spiff that makes partner reps compete with your direct team for the same deal makes the underlying problem worse while appearing to raise partner engagement.
When the answer is a plan change
Run the test before designing anything. If the behaviour you want is one you will still want in a year, the plan is wrong and a spiff is a way of avoiding the conversation. Permanent intent needs a change to the accelerators or the rate, not a patch that expires.
Spiffs earn their place on genuinely temporary needs: clearing legacy inventory, launching a product the team has no reflex for yet, covering a quarter where a segment is unusually soft. Short-lived cause, short-lived instrument. If you cannot name the date the need ends, you are not describing a spiff.
And if a spiff is being used to compensate for deals stalling or falling out, the money is going to the symptom. The stall has a cause, usually at a specific stage, and finding which stage loses the most is cheaper than paying around it.
Questions people ask
What is a spiff in sales?
A short-term cash incentive paid on top of commission for one named behaviour inside a set window, such as selling a specific product or attaching a service.
What is the difference between a spiff and a bonus?
A bonus pays for clearing a threshold such as quota. A spiff pays per occurrence of one specific action, for a limited time, and sits outside the standing plan.
Do sales spiffs actually work?
On genuinely temporary needs, yes. The common failure is pull-forward, where a quarter-end spiff pays a premium on deals that were already closing and empties the next quarter.
How long should a spiff run?
Long enough to act on and short enough to stay salient, with a published end date that is honoured. One that runs several quarters has become part of the plan without review.
When should you change the comp plan instead?
When the behaviour is one you will still want in a year. Permanent intent belongs in the rate or the accelerators, not in a patch designed to expire.
