Low Voltage Wiring Installation Financial Model Template For Founders, Bids, And Investor Decks

What are the primary revenue drivers?

Your revenue is driven by the number of active customers, the average billable hours per project, and your hourly rate for each service. The model forecasts revenue based on your marketing spend and customer acquisition cost (CAC), which starts at $450 and decreases to $350 over five years. This approach allows you to directly link marketing investment to top-line growth, projecting revenues from $713k in year one to $5.7M in year five.

Core Revenue Streams

• Structured Cabling: Billed at an initial rate of $95/hour.
• Security Integration: Billed at a higher rate of $115/hour.
• AV Systems: Billed at a premium rate of $125/hour.

What is the path to profitability?

You'll reach profitability by managing direct costs and scaling your team efficiently. The model shows positive EBITDA of $16k in the first year, growing substantially to $2.67M by year five. This trajectory is achieved by controlling the Cost of Goods Sold, like raw materials (18% of revenue initially), and by strategically hiring technicians as your customer base expands, ensuring labor costs don't outpace revenue growth.

Improving Profitability

• Negotiate bulk discounts on raw materials.
• Optimize technician scheduling to maximize billable hours.
• Focus sales efforts on higher-margin services like AV systems.
