A SPIFF (Sales Performance Incentive Fund) is a short-term bonus paid to salespeople for completing a specific action — selling a particular product, booking a set number of demos, or hitting a goal inside a defined window. It is paid on top of regular commission, and it ends when the window closes.
That last part is what makes a SPIFF a SPIFF: it is temporary and targeted. Commission rewards everything a rep sells, forever. A SPIFF points the team's energy at one number, for one sprint.
Commission is the engine. A SPIFF is the turbo button — brief, directional, and expensive if you hold it down all year.
| SPIFF | Commission | Bonus | |
|---|---|---|---|
| Timeframe | Days to weeks | Permanent | Quarterly / annual |
| Trigger | One specific action | Every closed deal | Hitting quota or MBO |
| Amount | Flat, known upfront | % of deal value | % of salary or target |
| Best for | Steering behavior now | Rewarding revenue | Rewarding consistency |
SPIFFs work when there is one behavior you need more of right now. The classic use cases:
- Product launch. First 10 deals of the new SKU earn $500 each — reps learn to pitch it fast
- Stalled inventory or dying quarter. Flat payout on any deal that closes before month end
- A funnel metric that's bleeding. Fastest average lead response this month takes $1,000 — behavior SPIFFs beat outcome SPIFFs for coachable metrics
- Pipeline building. $50 per qualified meeting booked this sprint, capped per rep
- Channel attention. Vendor SPIFFs paid to partner reps who lead with your product
Notice the third one. The highest-leverage SPIFFs target the speed metrics reps fully control — response time, follow-up cadence, quote turnaround — not just closed revenue, which arrives too late to steer.
- Short window. Two to six weeks. Longer, and it's just a worse commission plan.
- One number. A SPIFF with three conditions steers nothing. Pick the single behavior.
- Pay fast. Payout inside the same pay cycle. Delayed SPIFFs lose their charge.
- Cap the spend. Per-rep caps and a total budget — SPIFFs on uncapped metrics get gamed.
- Announce the end. A SPIFF that quietly becomes permanent trains reps to wait for the next one.
Before you SPIFF a lagging number, audit why it lags. Paying reps to push through a broken process buys the symptom, not the cure — if quotes take two weeks because approvals take twelve days, no incentive fixes it.
What does SPIFF stand for?
SPIFF is most commonly expanded as "Sales Performance Incentive Fund" (sometimes "Sales Performance Incentive Funding Formula"). The word predates the acronym — 19th-century drapers paid a "spiff" to clerks who sold unwanted stock — so the expansion is a backronym, and you will see both SPIFF and SPIF used.
Is it SPIFF or SPIF?
Both spellings are used interchangeably. SPIFF with two Fs is the more common form in sales organizations and the one we use. There is no difference in meaning.
Are SPIFFs taxable?
Yes. For employees, cash SPIFFs are supplemental wages subject to payroll taxes. SPIFFs paid by a manufacturer directly to a reseller's reps are typically reported as 1099 income. Non-cash prizes are taxable at fair market value. Confirm treatment with your payroll or tax advisor.
What is the difference between a SPIFF and a commission?
Commission is the standing percentage of every deal a rep closes — permanent and formula-based. A SPIFF is a temporary, flat-amount incentive attached to one specific action for a defined window, layered on top of the regular plan.
What is a SPIFF in car sales?
Dealerships use SPIFFs to move specific units — a flat cash amount for selling an aged vehicle, a slow trim, or a finance product this weekend. It is the same mechanic as B2B SPIFFs: short window, specific target, instant payout.
