Rainwater harvesting and greywater systems require skilled installers, system designers, and customer-facing roles—but compensating your team fairly while staying profitable is a common stumbling block for growing businesses in this space. Your sales structure directly impacts both the quality of leads you close and the team's motivation to upsell high-value system upgrades. Here's how to build a compensation model that works.
Understanding Your Market Position
The rainwater harvesting sector spans residential retrofit projects (typically $3,000–$15,000), commercial installations ($20,000–$150,000+), and ongoing maintenance contracts. Your compensation strategy must reflect where you're competing. A team selling $8,000 residential systems operates differently than one moving $50,000 commercial greywater reuse installations for office parks.
Start by calculating your average project value and gross margin. Most established rainwater and greywater companies maintain 35–50% margins after labor and materials. If your average system sells for $10,000 with a 40% margin, you have $4,000 to allocate across labor, overhead, and commission.
Sales Commission Structure for Hardware & Installation
Direct commission on system sales typically ranges from 8–15% for inside sales roles and 10–20% for outside/field sales roles in this niche. Here's what works:
Pure commission model: Best for experienced reps already in your network. Offer 12–18% of gross profit (not revenue) per closed project. A rep closing three $10,000 systems monthly at 40% margin earns $1,440–$2,160. This attracts hungry performers but creates cash-flow volatility.
Base + commission hybrid: More sustainable for building a stable team. A typical structure:
- Base salary: $35,000–$45,000 annually (inside sales) or $45,000–$60,000 (outside sales with vehicle/travel costs)
- Commission: 5–10% of gross profit on closed deals
- Bonus: 2–5% for upsells (smart controls, larger cistern capacity, greywater distribution upgrades)
This encourages consistent effort while protecting your reps' income.
Structuring Your Sales Roles
Most growing rainwater harvesting companies need at least two distinct roles:
Lead generation / inside sales: Handles incoming inquiries, qualification calls, and site assessments. Compensation: $40,000–$50,000 base + 4–6% commission on converted projects. Expect 15–25 qualified leads monthly from your website, referrals, and directory listings. Being visible on platforms like Mercoly helps you attract consistent inbound leads that your inside team can convert.
Account managers / outside sales: Manages existing customers, oversees installations, and develops ongoing maintenance contracts. Compensation: $50,000–$65,000 base + 5–8% on new work + 10–15% on recurring maintenance contracts (these are gold—they're predictable and have high margins). One account manager can typically manage 40–60 active customer relationships.
Adding Incentives Beyond Commission
Commission alone won't drive behaviors you actually need. Layer in these incentives:
- System design bonuses: +2% for systems that exceed budget targets (customers buying larger tanks or dual greywater loops)
- Referral bonuses: $300–$800 per customer referral that converts (rewards word-of-mouth, which is huge in this niche)
- Seasonal targets: Q3–Q4 are peak installation windows. Offer 1.5x commission multiplier in high-volume months
- Team bonuses: If monthly revenue hits a target (say, $50,000), split 3–5% of overages among the whole team. This reduces cutthroat behavior and builds culture
Common Pitfalls to Avoid
Don't pay commission on revenue—always tie it to gross profit or you'll incentivize your reps to discount aggressively on high-complexity jobs. You'll eat the margin loss while they pocket commission.
Avoid paying commission on quotes or estimates. Only pay when the customer has signed and paid a deposit. Too many rainwater companies bleed money on commissioned "sales" that never close.
Don't ignore your maintenance and service revenue. Service contracts (tank cleaning, filter replacement, system inspections) are where many rainwater companies lock in 60%+ margins. Make sure your compensation plan rewards this work, not just new installations.
Scaling Your Team
As you grow from 1 to 3 salespeople, your overhead should drop from 35% of revenue to 25–28%. This is where accurate tracking matters—use simple CRM software ($50–150/month) to track pipeline, close rates, and average deal size. You'll spot inefficiencies fast.
Hiring your second salesperson is the hardest move; the third becomes much easier once you have repeatable processes and proven compensation.
Frequently Asked Questions
Q: What's a realistic close rate for residential rainwater systems? Most established teams convert 15–30% of qualified leads into closed projects; newer teams average 10–15%. Your close rate directly affects how many leads your inside sales person needs to hit revenue targets.
Q: Should I pay commission on maintenance contracts differently than new installations? Yes—maintenance contracts should pay higher commission (10–15%) because they're lower-effort, recurring revenue that sticks around for years.
Q: How do I know if my commission rates are competitive? Talk to other rainwater and greywater installers in your region (they're usually friendly about this), check job boards for salary data, and track your reps' actual earnings. If top performers are earning less than $70,000–$90,000 annually at your company, you're likely losing them to competitors.
