Running Cost 1
: Payroll and Wages
Fixed Salary Burn
Your 2026 payroll commitment is $704,000 annually for 9 full-time staff. This fixed cost averages $58,667 monthly and covers everyone from the CEO down to the Certified Installers doing the actual shaft work. You must cover this before invoicing starts.
Calculating Payroll Overhead
Payroll and Wages is a fixed overhead expense that must be covered regardless of project volume. You need precise salary agreements for all 9 roles, including the CEO and Certified Installers, to lock in the $704,000 annual figure. This commitment hits your budget first.
Total fixed annual salary: $704,000.
Headcount includes 9 full-time staff.
Monthly average: $58,667.
Staffing Cost Control
Managing fixed payroll means timing hires to match project pipeline certainty. Since these are specialized roles, you can't easily cut Certified Installer wages without losing quality or compliance guarantees. Focus on keeping administrative overhead lean until revenue scales. Defintely phase in roles slowly.
Stagger hiring past the initial launch.
Ensure high utilization for installers.
Keep non-billable staff count low.
Utilization Impact
Because $58,667 is the baseline monthly burn for salaries alone, your project pricing must aggressively cover this fixed cost. If your specialized crews sit idle, this fixed expense quickly erodes contribution margin from billable work, making utilization rates critical to profitability.
Running Cost 2
: Rent and Utilities
Fixed Space Cost
Your fixed overhead for physical space runs $7,450 every month. This covers the warehouse and office rent, plus essential utilities and communications services needed to run operations. This cost is non-negotiable unless you downsize your footprint.
Space Breakdown
This $7,450 figure is pure fixed overhead, meaning it doesn't change whether you build one shaft or ten. It combines $6,500 for the physical lease of the warehouse and office space. You also add $950 for utilities and communications. This is a baseline cost you pay before any revenue hits the bank.
Warehouse/Office Rent: $6,500
Utilities/Comms: $950
Optimization Tactics
Fixed rent is hard to move quickly, but you can negotiate renewal terms early. For utilities, audit your communication plans; maybe you're paying for too much bandwidth. If you can operate with a smaller warehouse or move to a lower-cost industrial zone, savings could be substantial. Honestly, this is defintely a long-term lever.
Audit communication service tiers.
Renegotiate lease terms early.
Consider shared industrial space.
Overhead Impact
At $7,450 monthly, this rent and utility cost needs to be covered by your gross profit margin before you pay salaries or insurance. Compare this against your $704,000 annual payroll to see how much revenue volume is required just to keep the lights on and the doors open.
Running Cost 3
: Insurance and Compliance
Fixed Compliance Overhead
Insurance and compliance costs hit $4,650 per month, making it a non-negotiable fixed overhead. This covers your General Liability and Workers Comp, plus mandatory Professional Association Dues. This spend must be covered before you see profit on any project.
Cost Breakdown
Your fixed compliance overhead is $4,200 monthly for critical liability coverage and Workers Comp insurance. Add $450 for required Professional Association Dues. These inputs are based on crew size and project risk exposure, not direct revenue. This is a baseline cost you pay regardless of job volume.
Liability coverage is $4,200/month.
Dues total $450 monthly.
These are fixed obligations.
Managing Spend
You can't cut liability insurance, but you can shop quotes annually. If your specialization reduces inherent risk, negotiate lower Workers Comp premiums after year one. Avoid letting dues lapse; non-compliance voids your code guarantee. This cost is defintely tied to your 100% compliance guarantee promise.
Shop insurance quotes yearly.
Use specialization to lower premiums.
Don't skip association dues payments.
Fixed Cost Impact
Because this $4,650 is fixed, your first priority must be securing enough high-margin projects to absorb it quickly. If payroll is $58,667 monthly, this compliance spend is about 8% of your fixed salary base. You need consistent revenue flow to cover this before factoring in variable COGS.
Running Cost 4
: Project Materials (COGS)
Material Cost Shock
Your material costs are unsustainable right now. In 2026, Project Materials (COGS) are forecast at 190% of revenue, driven by 125% for core items and 65% for safety gear. This structure guarantees massive losses before you even pay your installation crews.
Material Cost Breakdown
This estimate comes from combining two huge material buckets for 2026 projections. Fire-Rated Sealants and Specialized Fasteners alone consume 125% of revenue. Add 65% for Job-Specific Safety and Testing Consumables. If revenue hits $1M, materials cost $1.9M-a serious structural issue for a specialty contractor.
Fasteners and Sealants: 125% of revenue
Safety and Testing Gear: 65% of revenue
Taming Material Spend
You must aggressively negotiate supplier contracts for those sealants and fasteners now. Standardize safety consumables across all job types to gain volume discounts. If you can cut the 125% component down to 50%, you move toward viability. What this estimate hides is the impact of material waste on site.
Lock in supplier pricing early
Reduce inventory holding costs
Standardize component lists
Immediate Pricing Review
Review your entire project pricing model right away. Current pricing must cover 190% COGS, plus 95% in variable travel/inspection fees, plus $58,667 monthly in fixed payroll. You are defintely underpricing by a huge margin if these material assumptions hold true for your scope of work.
Running Cost 5
: Vehicle Fleet Maintenance and Fuel
Fleet Cost Fixed
Fleet maintenance and fuel is a fixed monthly operating expense of $2,800. This cost supports moving your specialized installation crews and necessary materials between various commercial job sites daily. Since it's fixed, it doesn't scale with immediate project volume, making accurate initial budgeting critical for cash flow planning.
Fleet Budgeting
This $2,800 monthly figure represents expected operational costs for the fleet needed to service projects. To verify this, you need to model the number of trucks used times the estimated monthly fuel burn and scheduled preventative maintenance. It sits alongside payroll and rent as core overhead before revenue starts flowing.
Estimate fuel based on projected monthly miles.
Factor in mandatory state safety inspections.
Include costs for 9 employees needing transport.
Cutting Fuel Burn
Managing this fixed cost means maximizing crew efficiency per trip. Poor route planning or deferred maintenance quicklly erodes this budget line. Focus on dense scheduling within specific geographic zones to lower non-billable miles. A good goal is keeping fleet utilization above 90% during operational hours.
If a primary service vehicle breaks down unexpectedly, the $2,800 estimate is immediately insufficient. Unplanned repairs or emergency rentals can spike this cost significantly, delaying crew deployment and risking penalties on critical path construction timelines. This cost must include a small contingency buffer, maybe 10%.
Running Cost 6
: Inspection and Travel Fees
Travel and Inspection Cost Sink
Your direct variable costs are crushing potential margins, as travel and inspection fees consume 95% of project revenue. This structure means pricing must be aggressive, or profitability will be impossible before fixed overhead even hits the books.
Variable Cost Setup
These costs are tied directly to job execution and compliance sign-off. Project-Specific Travel and Logistics demand 50% of revenue, covering crew deployment. Inspection Fees add another 45% for required third-party sign-off, making the total variable burden 95%. This leaves only 5% contribution margin before fixed costs.
Travel: 50% of revenue
Inspections: 45% of revenue
Total Direct Variable Load: 95%
Controlling Travel Drag
You can't eliminate inspection fees, but you can control travel drag. Focus on securing larger, fewer projects clustered geographically to reduce logistical costs per job. Negotiate bulk rates with inspection agencies early in 2026 to chip away at that 45% burden. If onboarding takes 14+ days, churn risk rises, defintely impacting cash flow.
Prioritize job density over volume
Lock in multi-project travel discounts
Audit inspection fee schedules
Pricing Reality Check
Your margin structure is extremely thin due to these direct variable loads. If your project pricing doesn't explicitly account for a 95% variable cost ratio, you will lose money on every single job completed, regardless of overhead levels.
Running Cost 7
: Software and Marketing
Fixed Tech and Outreach
Software and marketing require a fixed commitment of $2,350 per month to run operations and secure future work. This covers essential tools for project costing and the budget allocated for lead generation in 2026. You need these systems running before the first crew mobilizes.
Software Licensing Costs
The $1,100 monthly software expense covers critical fixed licenses for Estimating and Enterprise Resource Planning (ERP) systems. These tools manage job costing, material take-offs, and project timelines, which is crucial when dealing with complex, code-driven construction. If onboarding takes 14+ days, churn risk rises.
Estimating software checks material quantities.
ERP tracks labor and billing flow.
This is a non-negotiable fixed overhead.
Marketing Budget Allocation
Marketing spend is set at $1,250 monthly based on the $15,000 annual budget for 2026. Since you target general contractors, focus spending on trade shows and specialized digital outreach rather than broad advertising. Don't defintely overspend early on brand awareness before securing initial anchor projects.
Target contractor events first.
Measure ROI per lead source.
Review annual budget quarterly.
Total Fixed Tech Spend
Totaling $2,350 monthly, software and marketing are fixed costs that must be covered regardless of project volume. Since your COGS is high at 190% of revenue, maintaining tight control over these SG&A expenses is vital to reaching profitability quickly.
