For a professional outdoor lighting company, calculating the true cost of a sale goes far beyond the price of a brass fixture or a spool of low-voltage wire. To maintain healthy margins, a business must accurately calculate its selling costs—the total expense required to acquire a customer and finalize a contract.
Understanding these costs breaks down into three core categories:
1. Customer Acquisition Costs (CAC)
This is the total investment required to get the phone to ring. It includes digital marketing, local Search Engine Optimization (SEO) to capture regional searches, and maintaining a high-quality, informative website. To find the marketing cost per sale, divide your total advertising spend over a specific period by the number of closed contracts generated during that same window.
2. Design and Consultation Time
Unlike over-the-counter retail, architectural lighting requires custom design. This phase involves physical site visits, and creating detailed layout plans. The selling cost must factor in:
- The hourly wages or commission for the designer.
- Vehicle fuel and wear-and-tear traveling to the property.
- The time spent drafting the formal proposal and itemized estimate.
3. Overhead Allocation
A portion of fixed business expenses (Overhead) must be distributed across every sale. This includes rent, utilities, government fees, office pesonnel, vehicle expenses including gas, cost of tools, direct mail costs, CRM software for tracking leads, and warehouse expenses for storing commercial-grade inventory.
The Bottom Line:
By tracking these expenses, a landscape lighting business ensures its project pricing covers not just the physical installation, but the entire process of bringing a client from initial curiosity to a beautifully lit property.
