| Materials | Copper ~9,500 USD/t | price risk |
| SG&A | ~18% rev | mid‑sized firms |
Revenue Streams
Fixed-Price Contracts
Fixed-price contracts are lump-sum commercial builds with a defined scope where final margin hinges on execution quality and strict change-control; industry net margins averaged roughly 3–6% for general contractors in 2024. Incorporating prefab and value engineering routinely raises margins by 2–6 percentage points and cuts schedule risk. Common in office, retail, and institutional projects, these contracts transfer scope risk to the contractor, making cost forecasting and contingency critical.
Time & Materials
Billed labor hours plus materials with typical markups of 10–20% provide flexible revenue capture. Time & Materials suits uncertain scopes and service work where change orders are frequent. Transparent, itemized pricing builds client trust and, in 2024, drove invoice approval cycles roughly 30–40% faster versus fixed‑price projects, improving cash flow.
Service & Maintenance
In 2024 IES service & maintenance drives recurring revenue via preventative maintenance contracts and 24/7 service, delivering predictable cashflows and higher customer lifetime value. SLAs are tiered and priced by response time and geographic coverage to capture premium urgency fees. Upsells of retrofits and performance upgrades boost average contract value, while multi-site programs increase account stickiness and reduce churn.
