The business requires a minimum of $443,000 in cash reserves to sustain operations until the projected break-even point in April 2027.
Fixed monthly operating costs are substantial, exceeding $51,500 in 2026, driven primarily by a $40,417 payroll for six full-time employees.
Variable expenses are critically high, consuming 290% of revenue, with Direct Hardware (140%) and Subcontracted Labor (60%) being the largest cost drivers.
Profitability is not expected for 16 months, emphasizing the necessity of aggressive scaling to cover the high initial fixed and variable cost base.

Running Cost 1 : Wages and Salaries

Initial Payroll Burn

Initial monthly payroll for your starting team of six FTEs hits $40,417. You must manage this burn rate closely because headcount is projected to grow to 13 employees by 2030. That initial payroll sets your baseline fixed labor cost right out of the gate.

Cost Inputs

This initial $40,417 covers the first six full-time employees (FTEs) needed to run operations, including the General Manager, Designers, and Technicians. You calculate this by summing the fully loaded cost-salary plus benefits and taxes-for those specific roles. If your average loaded cost per person is about $6,729, that gets you to the starting monthly outlay. This is defintely your largest fixed labor expense.

Headcount: 6 FTEs initially
Role mix: GM, Designers, Technicians
Input: Fully loaded salary rates

Managing Headcount Growth

Scaling headcount to 13 by 2030 means careful hiring phasing is crucial. Avoid hiring overhead too early; use subcontractors, like the 60% variable labor cost you forecast, until revenue density supports a new hire. Track the revenue generated per employee (RPE) monthly to ensure each new salary dollar drives proportional growth.

Phase hiring based on utilization.
Use variable labor first.
Monitor revenue per employee.

Fixed Cost Pressure

Since this payroll is fixed, it pressures your contribution margin until revenue volume increases significantly. Every dollar paid to these six people must be supported by billable project revenue, or it erodes capital reserves quickly. Keep the GM focused purely on billable utilization.

Running Cost 2 : Warehouse and Office Rent

Fixed Rent Anchor

Warehouse and office rent is a fixed overhead cost holding steady at $6,500 per month across the entire five-year model. This predictable expense anchors your operational burn rate, meaning you must generate sufficient project revenue quickly to absorb it before hiring or variable component costs increase.

Estimating Space Needs

This $6,500 covers the baseline space needed for admin and light component storage supporting the initial six full-time employees (FTEs). You determine this by getting quotes based on required square footage for office work and inventory staging, treating it as an unavoidable fixed cost until revenue justifies expansion.

Get quotes for combined needs.
It supports initial staffing levels.
It's not tied to installation volume.

Managing Space Costs

Since rent is fixed, optimization means maximizing the utility of every square foot you pay for. Avoid signing multi-year leases until you have steady project flow, perhaps using flexible office space first. If you overpay for space early, it deflates your contribution margin on every job.

Maximize utilization immediately.
Delay facility expansion plans.
Use flexible terms where possible.

Overhead Impact

This $6,500 is a major fixed commitment, second only to initial wages at $40,417 monthly. You need strong gross margins on your installation projects to cover this cost quickly; if it's too high relative to your first few jobs, it's it's a major drain on working capital.

Running Cost 3 : Direct Hardware and Components

Hardware Cost Trajectory

Your direct hardware cost starts high at 140% of revenue in 2026, but you project better buying power, dropping this to 120% by 2030. This initial expense ratio is critical because it means your gross margin is negative until you scale volume or negotiate better pricing. Honestly, this ratio must improve fast.

Hardware Inputs

This variable cost covers all physical sensors, dimming modules, control units, and wiring needed for the installation. Inputs require accurate unit counts per project multiplied by negotiated supplier prices. Since the ratio is over 100%, you need tight control over initial supplier quotes to manage negative gross margins early on.

Calculate component cost per square foot.
Track vendor lead times closely.
Factor in freight costs separately.

Cutting Component Spend

To manage this 140% starting ratio, focus on securing volume discounts immediately after the first few successful projects. Avoid scope creep that adds unnecessary components to the bill of materials. A defintely goal is hitting 120% by 2030, but you need a plan to get below 100% sooner.

Standardize sensor packages across projects.
Negotiate payment terms early.
Review component substitution options.

Margin Reality Check

Since hardware costs exceed revenue initially, every project booked in 2026 loses money before labor or overhead. You must secure enough working capital to cover this 40% revenue gap on components alone. Focus sales efforts on larger, higher-margin jobs to absorb this initial hardware deficit quickly.

Running Cost 4 : Subcontracted Electrical Labor

Labor Cost Trajectory

Subcontracted labor starts high, consuming 60% of revenue in 2026, but the plan hinges on cutting this to 40% by 2030. This shift signals a defintely move toward building internal technical capacity rather than relying on external crews for installations.

Estimating External Spend

This cost covers paying external electricians for installation work, which is a major driver of gross margin early on. In 2026, if revenue hits projections, this variable spend will eat up 60 cents of every dollar earned. You need to track this percentage against total revenue monthly to see if the scaling strategy is working.

Track against total project revenue.
Input is external crew hours/rates.
High starting percentage means low initial margin.

Managing the Shift In-House

Reducing this expense requires hiring your own team, which shifts cost from variable (labor) to fixed (salaries). Current payroll for six FTEs is $40,417 monthly. To hit the 40% target by 2030, you must carefully manage the hiring ramp-up to absorb the work currently outsourced.

Hire technicians before subcontracting peaks.
Watch fixed overhead absorption rate.
Avoid relying on subcontractors post-2027.

Margin Impact Check

The gap between 60% in 2026 and 40% in 2030 represents a 33% improvement in variable cost structure. If you miss the 2030 target, profitability suffers because fixed overhead like rent ($6,500/month) remains constant regardless of labor efficiency.

Running Cost 5 : Online Marketing Budget

Marketing Spend Baseline

Your 2026 online marketing budget is set at $24,000 annually, or $2,000 per month. This spend is calibrated to acquire new commercial installation projects at a target Customer Acquisition Cost (CAC) of $1,200. Hitting this CAC means you need about 20 new projects that year.

Budget Calculation Inputs

This $2,000 monthly spend covers digital ads and content creation necessary to generate leads for your daylight harvesting systems. You calculate this by dividing your total desired annual marketing spend by your target CAC to find the number of customers you can afford to buy. If onboarding takes 14+ days, churn risk rises defintely.

Annual Budget: $24,000
Target CAC: $1,200
Acquired Customers: 20 projects/year

Managing Acquisition Cost

Since your target CAC is high at $1,200, focus on lead quality over volume immediately. Conversion rates from lead to signed contract must be tracked religiously. Avoid broad digital campaigns; target facility directors specifically via industry trade publications for better results.

Focus on high-intent leads.
Track lead-to-contract conversion.
Test channel ROI monthly.

CAC Versus Project Value

If your average project size yields revenue far exceeding $10,000 in gross margin, the $1,200 CAC is manageable. If projects are smaller, you must aggressively drive down acquisition costs below $800 quickly.

Running Cost 6 : Design Software Licenses

Fixed Software Spend

Software licenses are a fixed $1,200 monthly cost essential for all Site Audits and Design work. This spend supports the core technical output of the business. You need to budget this precisely before any revenue starts flowing to ensure you aren't caught short.

Budgeting the Tools

These licenses cover the necessary Design and Modeling Software used by your technical team to create accurate system plans. This is a predictable fixed cost of $1,200/month, separate from variable expenses like hardware (starting at 140% of revenue). It anchors your initial overhead alongside rent ($6,500/month).

Fixed software cost: $1,200 monthly.
Supports all Site Audits.
Essential for accurate system design.

Controlling License Use

You can't skimp on design tools, but you must manage user seats strictly. Avoid paying for licenses for staff who aren't actively designing or auditing sites right now. Check if annual prepaid plans save you 10% to 15% over month-to-month billing; it's defintely worth the upfront cash outlay if utilization is stable.

Monitor active user seats closely.
Check for annual prepayment discounts.
Avoid paying for dormant seats.

Fixed Cost Reality

This $1,200 is a non-negotiable fixed cost that must be covered by the first few projects monthly just to keep the lights on, technically speaking. It's a baseline operational requirement before you even start billing for labor or materials on any job.

Running Cost 7 : Fleet and Project Logistics

Logistics Cost Structure

Logistics costs start high in 2026, combining a fixed base with a significant variable component tied directly to sales volume. You must manage the 40% variable rate for Project Logistics and Freight to maintain margin as you scale revenue. Honestly, that variable portion needs immediate attention.

Fleet Cost Breakdown

This covers moving equipment and personnel to job sites. The fixed part is $1,500 per month for vehicle leases or base insurance. The variable part, Project Logistics and Freight, hits at 40% of revenue starting in 2026. This is a major component of your Cost of Goods Sold (COGS) structure.

Fixed base: $1,500/month.
Variable starts 2026.
Covers site transport costs.

Controlling Variable Freight

To control the 40% variable rate, you need route density. Grouping installations geographically reduces trips. Since Subcontracted Electrical Labor is also high at 60% in 2026, using your fixed fleet efficiently helps lower overall site costs. Defintely optimize scheduling.

Increase job density per zip code.
Negotiate freight contracts early.
Minimize technician non-billable travel time.

Early Margin Reality Check

Your combined variable costs (Hardware at 140%, Labor at 60%, Logistics at 40%) mean gross margin is severely compressed early on. The $1,500 fixed fleet cost is small compared to the 240% total variable overhead relative to revenue in 2026.
