A service center changed its sales compensation from a flat 1% of revenue to a tiered plan based on gross margin dollars. Within six months, average gross margin per ton increased by $8. On 60,000 tons of annual sales, that $8 improvement added $480,000 to the bottom line. The total increase in sales compensation was $95,000. The company netted $385,000 from a one-page policy change.
Why Revenue-Based Plans Fail
A sales rep paid 1% of revenue earns $100 on a $10,000 order regardless of whether the margin is $1,500 or $300. The rep has zero incentive to hold price. In fact, they have an incentive to drop price to close the deal because their commission is the same either way and a bird in hand is worth more than a negotiation that might not close.
Revenue-based plans also create equal incentives for all business. A $10,000 commodity order that required one phone call pays the same as a $10,000 specialty order that required sourcing, technical support, and three follow-up calls. The rep gravitates toward easy volume and avoids the harder, higher-margin work.
Margin-Based Compensation Structures
The most effective structure for steel distribution pays a percentage of gross margin dollars. A common range is 8% to 12% of gross margin. On a $10,000 order with a $1,500 margin, the rep earns $120 to $180. On the same revenue with a $300 margin, they earn $24 to $36. Now the rep has a direct financial incentive to negotiate better pricing and focus on higher-margin products and customers.
Tiered margin plans add acceleration. Below target margin per ton, the rep earns 8% of gross margin. At target, 10%. Above target, 14%. This acceleration encourages reps to push for better margins rather than settling at the minimum. The incremental commission cost is small relative to the margin improvement it drives.
Base Salary vs. Commission Split
Pure commission (no base salary) attracts aggressive sellers but creates high turnover and can lead to short-term thinking that damages customer relationships. Pure salary with no commission creates no urgency and no differentiation between top performers and coasters. The sweet spot for steel distribution is a 60/40 to 70/30 split: 60% to 70% base salary, 30% to 40% variable compensation tied to margin performance.
The base salary should be high enough that the rep can pay their bills without hitting quota. The variable component should be meaningful enough that hitting and exceeding quota creates a noticeable income difference. For a rep targeting $150,000 total compensation, that means a base of $90,000 to $105,000 and variable potential of $45,000 to $60,000.
What Else to Incentivize
Beyond margin, consider adding smaller incentive components for new account acquisition (a bonus for each new account that reaches $50,000 in annual revenue), account growth (a bonus for growing existing accounts by more than 10% year over year), and product mix expansion (a bonus for selling products from underperforming categories). Keep these supplemental incentives to 10% to 15% of total variable compensation. The primary driver should always be margin.
Communication and Transparency
The most important element of any compensation plan is that the rep can calculate their own paycheck. If the plan is so complex that reps cannot figure out what they will earn on a given deal, it will not change behavior. Give every rep access to their margin data, their commission calculations, and their progress toward targets. Real-time visibility into their earnings drives the daily decisions that compound into annual results.
Review and adjust the plan annually. Market conditions, company goals, and competitive dynamics change. A plan that worked three years ago may need tuning. But avoid mid-year changes unless absolutely necessary. Changing the rules mid-game destroys trust and demotivates your best performers.
