Sales Commission Structures Explained: 7 Models with SaaS Examples
There is no single correct commission structure. There is only the one that aligns with what your company actually needs reps to do. The structure you choose shapes behavior more directly than quota targets, comp plan documents, or motivational speeches ever will.
Here are seven commission structures commonly used in B2B SaaS, with notes on where each one works and where it tends to break down.
1. Flat rate commission
A fixed percentage of every dollar closed. If the rate is 10% and a rep closes $50,000, they earn $5,000. No tiers, no thresholds, no complexity.
This works well for early-stage companies with simple products and relatively uniform deal sizes. It’s easy to explain, easy to calculate, and reps always know what a deal is worth. The downside is that it offers no extra motivation to push past quota. A rep who is at 80% of target and a rep at 120% earn the same rate per dollar.
2. Tiered commission
Different commission rates apply at different levels of attainment. A plan might pay 8% on the first $500,000 of bookings and 12% on everything above that. The rate increases as the rep climbs through defined thresholds.
Tiered structures reward overperformance and create natural incentive curves. They’re the most common structure in mid-market and enterprise SaaS. The risk is complexity. If you have more than three tiers, most reps will stop tracking where they stand, which defeats the purpose.
3. Accelerators
Accelerators increase the commission rate after a rep exceeds 100% of quota. Where a tiered plan changes rates at fixed dollar thresholds, an accelerator kicks in at attainment milestones. A rep might earn 10% up to quota and 15% on everything above it.
This is the standard model for companies that want to reward top performers disproportionately. The economics work when the incremental revenue from overperformance is high-margin. If your product has low marginal cost of delivery, accelerators let you share the upside without hurting unit economics.
4. Draw against commission
A draw provides a guaranteed minimum payment that is later recovered from earned commissions. In a recoverable draw, the company advances $5,000 per month and deducts it from the rep’s commission earnings. A non-recoverable draw is essentially a guaranteed floor that the rep keeps regardless.
Draws are most useful during ramp periods for new hires or when entering new markets where pipeline takes time to build. The operational complexity is real. Tracking draw balances, handling negative balances at period end, and deciding what happens when a rep leaves with an outstanding draw all require documented policies.
5. Multiplier-based commission
A multiplier adjusts the base commission rate based on a secondary factor. If the company wants reps to prioritize multi-year deals, it might apply a 1.2x multiplier on three-year contracts and a 0.8x multiplier on month-to-month. The base rate stays the same; the multiplier shifts it.
Multipliers work well when you need to weight certain behaviors without redesigning the entire plan. They become problematic when stacked. Three overlapping multipliers on a single deal make it nearly impossible for a rep to estimate their payout, and impossible for operations to explain it.
6. Gross margin commission
Instead of paying on revenue, this structure pays a percentage of the gross margin on each deal. A $100,000 deal with 70% margin generates $70,000 in gross profit, and the rep earns their rate on that figure.
This is common in businesses where deal profitability varies significantly, such as services-heavy sales or highly customized implementations. It aligns the rep with the company’s actual economics. The downside: it requires reps to have visibility into margins, which many organizations are not comfortable sharing. And it creates perverse incentives if margin calculations are opaque or inconsistent.
7. Hybrid structures
Most real-world SaaS comp plans are hybrids. A typical enterprise AE plan might combine a tiered commission on new logo bookings with an accelerator above quota and a multiplier for multi-year terms. An SDR plan might use a flat rate per qualified meeting plus a bonus for pipeline conversion.
The key with hybrids is restraint. The best plans use two or three mechanics, not five. Every additional lever adds operational overhead in calculation, explanation, and dispute resolution. If a rep cannot explain their plan to a colleague in under two minutes, the plan is too complicated.
Choosing the right structure
The structure should follow the behavior you want. If you need consistent production, flat or tiered works. If you need quota-beating performance, accelerators earn their complexity. If you need reps to prioritize certain deal types, multipliers or margin-based plans do the work.
Whatever you choose, document it clearly, model the cost at various attainment levels, and make sure operations can calculate it cleanly every period. A brilliant commission structure that nobody can execute accurately is worse than a simple one that runs on time.
