Running Cost 1
: Staff Wages
Payroll Baseline
Staff wages are your primary fixed burden heading into 2026. Core payroll for 20 full-time employees (FTEs), comprising Lead Specialists and Senior Modelers, hits $17,500 monthly, making it the single largest expense line item. Managing this headcount directly controls your baseline burn rate.
Headcount Build
This $17,500 covers the base salaries for your 20 core technical staff required to deliver Building Information Modeling (BIM) services. To calculate this, you need the average loaded cost per role (salary plus benefits/taxes) multiplied by the number of hires planned for 2026. It’s the foundation of your operating expense structure.
Target FTE count: 20
Role mix: Lead Specialist, Senior Modeler
Monthly payroll total: $17,500
Controlling Payroll
Since this cost is fixed, optimization means avoiding premature hiring or ensuring utilization stays high. If you hire too fast, you'll carry excess salary expense before revenue catches up. A common mistake is forgetting the loaded cost—what you actually pay the company, not just the salary.
Stagger hiring based on pipeline.
Use subcontractors for demand spikes.
Track utilization rates closely.
Burn Rate Anchor
This $17.5k payroll sets your minimum monthly operational floor, excluding rent and software. If project revenue dips in Q3 2026, this large fixed commitment means you need significant cash reserves or immediate cost-cutting levers ready to deploy. It's defintely the first place auditors look.
Running Cost 2
: Core BIM Licenses
Fixed Tech Spend
Your baseline technology commitment for essential modeling tools is $1,200 per month. This fixed cost covers the core Building Information Modeling (BIM) software seats needed for your team, regardless of project load. You must budget for this before any revenue comes in.
License Cost Basis
This $1,200 monthly covers essential, non-project-specific software licenses required for all modeling staff. To calculate this, you need the exact seat count multiplied by the recurring monthly subscription fee for the base platform. It sits firmly in the fixed technology overhead, separate from variable project software fees.
Seats x Unit Price = Monthly Cost
Fixed, not tied to utilization
Compare against $17.5k payroll
Managing Seats
Avoid over-provisioning seats early on; only purchase licenses for active modelers. If you plan for 20 FTEs, you need 20 seats minimum, but check if annual commitments offer a discount versus monthly billing. Don't confuse these core licenses with variable project software fees.
Negotiate annual vs. monthly rates.
Track license utilization closely.
Avoid buying seats for pipeline staff.
Fixed Cost Reality
This $1,200 is a hard floor for your technology expense, meaning your break-even point calculation must absorb it monthly. If you only have 10 active modelers but pay for 20 seats, you are effectively paying 50% extra in unused fixed overhead.
Running Cost 3
: Office Space Rent
Fixed Rent Reality
Your dedicated commercial office space sets a baseline fixed cost of $3,500 per month. This expense hits your Profit and Loss statement regardless of how many Building Information Modeling (BIM) projects you complete. You must cover this before calculating operational profitability.
Rent Inputs
This $3,500 covers the lease obligation for your physical operational hub. To budget accurately, you need the signed lease term and the quoted monthly rate. This is a non-negotiable fixed overhead item in the 2026 budget structure.
Lease agreement term
Quoted monthly rate
Required square footage
Cutting Overhead
If operations allow, avoiding a dedicated space cuts this $3,500 immediately. If you must have space, negotiate a shorter initial term or use co-working memberships first. Don't over-commit on square footage early on.
Explore co-working options first
Delay signing long leases
Negotiate tenant improvement allowances
Rent vs. Variable Load
Compared to your $17,500 staff wages and $1,200 core licenses, the rent is manageable, but it must be covered by gross profit from billable hours. If you scale down to remote work, you save $3,500 monthly, which is $42,000 annually. That's defintely meaningful savings.
Running Cost 4
: Project Software Fees
Project Fee Leverage
Project software fees scale directly with sales, consuming 80% of project revenue immediately. This cost structure means your effective gross margin is determined by how efficiently you deploy these variable licenses per billed hour. You defintely need tight control here.
Cost Breakdown
These fees cover essential, project-specific software licenses and third-party data libraries needed for modeling work. Since this is 80% of revenue, you estimate it by multiplying projected monthly revenue by 0.80. This cost varies directly with sales volume, unlike fixed payroll.
Covers 50% for specific licenses.
Includes 30% for data libraries.
Needs sales volume forecasts.
Managing Variable Fees
Managing this cost means tightly controlling utilization and avoiding scope creep that demands unbudgeted library access. If onboarding takes 14+ days, churn risk rises because you might absorb license costs before revenue starts flowing. Track this closely.
Tie license use to billable milestones.
Negotiate bulk deals for common libraries.
Track utilization vs. core license costs.
Margin Reality Check
Because 80% of project revenue covers these variable fees, your true gross margin is only 20% before factoring in staff wages or overhead. Focus intensely on utilization rates; any idle time means you are paying for software access that isn't generating income.
Running Cost 5
: Specialist Subcontractors
Subcontractor Leverage
Subcontracted specialists are your primary scaling mechanism, absorbing 80% of 2026 revenue. This cost structure demands tight control over project scoping to ensure subcontractor utilization directly drives profitable service delivery. If you aren't tracking subcontractor efficiency, you're losing margin fast.
Cost Calculation
This 80% of revenue expense covers specialized BIM modeling or niche engineering support you don't staff internally. Estimate this by multiplying required specialist hours by their agreed hourly rate, then applying it against the total project billing. It’s a direct pass-through cost tied to sales volume.
Inputs: Specialist hourly rate, billed hours.
Impact: Directly reduces Gross Profit Margin.
Benchmark: 80% is high; requires high utilization.
Managing Variable Scale
Since subcontractors hit 80% of revenue, avoid using them for tasks the 20 core FTEs can handle. Standardize subcontractor agreements to include scope caps or tiered pricing based on volume commitment. If onboarding takes 14+ days, churn risk rises. Don't let scope creep inflate these variable costs past the planned 80%; defintely lock down SOWs.
Mandate clear SOWs (Statements of Work).
Negotiate volume discounts upfront.
Use them only for specialized needs.
Capacity Lever
Your 20 core staff manage baseline operations, but subcontractors manage capacity spikes. If you project revenue growth beyond what 20 FTEs can handle, ensure your subcontractor pipeline is vetted and ready to absorb the work without quality decay. This is your key operational lever for 2026.
Running Cost 6
: Customer Acquisition
Acquisition Budget Reality
Your $25,000 annual marketing spend in 2026 must support a high $2,500 target Customer Acquisition Cost (CAC). That budget breaks down to roughly $2,083 per month for securing new architectural, engineering, and construction (AEC) clients. This CAC is high, so the Lifetime Value (LTV) must defintely support it.
Acquisition Budget Setup
This $25,000 covers all marketing efforts aimed at securing new clients for your specialized Building Information Modeling (BIM) services. It’s a fixed allocation against variable revenue, meaning you must track every dollar spent against the resulting billable hours. If you spend $2,083 monthly, you need to know exactly which channels drive the final sale.
Managing CAC Risk
A $2,500 CAC is only viable if the average client engagement yields significant profit. Since project software fees and specialist subcontractors already consume 80% of project revenue, your margin on the remaining 20% must absorb this acquisition cost quickly. Focus on securing larger, longer-term contracts.
Track channel ROI closely.
Prioritize referrals over cold outreach.
Ensure LTV is 3x CAC minimum.
CAC Viability Check
To justify acquiring a client for $2,500, you need to calculate how many billable hours that client must purchase. If your blended hourly rate is $150, you need about 17 hours of billable work just to break even on acquisition costs, before covering your $17,500 core payroll.
Running Cost 7
: Utilities and Fixed Overhead
Fixed Infra Costs
Your essential administrative and infrastructure costs—utilities, insurance, cloud services, and accounting—are fixed at $2,050 per month. This baseline spend must be covered before any revenue hits the door. It’s non-negotiable overhead supporting your Building Information Modeling (BIM) operations.
Admin Cost Breakdown
This $2,050 covers necessary operational glue for your service. Accounting fees are usually fixed monthly retainers, while insurance requires annual quotes projected monthly. Cloud services depend on storage needs, but utilities are based on the office space rent ($3,500/month). You need firm quotes for insurance and accounting to lock this number down defintely.
Utilities and office overhead.
Mandatory business insurance policies.
Core cloud storage needs.
Monthly accounting retainer.
Controlling Fixed Spend
You can’t slash fixed costs easily, but you can manage the variable components within this bucket. Review your cloud storage usage quarterly; often, scaling down unused licenses saves money fast. For insurance, shop providers annually, aiming for a 5% to 10% reduction by bundling policies if possible. Don't let accounting fees creep up without reviewing scope.
Audit cloud usage every quarter.
Shop insurance annually for better rates.
Ensure accounting scope is tight.
Overhead Context
Compared to $17,500 in staff wages and $1,200 in core BIM licenses, this $2,050 is small, but it’s pure fixed burn. If you have zero billable hours, this amount, plus wages and licenses, is what you pay every single month. It's the minimum viable operational cost floor.
