Which BIM clash detection expenses stay fixed, and which move with sales?

Cost classification

Clean break-even math depends on putting each expense in the right bucket. If fixed payroll, software seats, or usage fees are misclassified, the Month 5 break-even target can look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent ($4,500/month)	Fixed	Keep in monthly overhead until the lease or footprint changes.	Spreading rent by project and hiding the true monthly hurdle.
Software Licenses Subscription ($2,800/month)	Fixed	Include as baseline overhead for model review capacity.	Ignoring paid seats needed before billable hours arrive.
Utilities and Internet ($600/month)	Semi-variable	Model the base service monthly, then flex usage with team activity.	Treating all connectivity spend as fixed while file traffic grows.
Salaried delivery team ($33.3k/month in first year)	Semi-fixed	Hold flat within current capacity, then step up when hiring expands.	Treating coordinators and engineers as fully variable labor.
Freelance VDC Support (12% of revenue in first year)	Variable	Apply as a revenue-linked delivery charge in gross margin.	Forgetting extra review hours on revision-heavy projects.
Cloud Computing and Storage (5% of revenue in first year)	Variable	Tie to model volume, storage, and processing demand.	Leaving usage charges in overhead instead of contribution margin.
Sales Commissions (5% of revenue)	Variable	Deduct from each sale when calculating contribution margin.	Counting booked revenue before the commission load.
Annual Marketing Budget ($45,000 in first year)	Semi-fixed	Plan as a committed spend level that changes in budget steps.	Assuming marketing falls automatically when sales slow.

How does break-even change from lean to full utilization for a clash detection service?

Scenario table

Mixing $145 retainer, $175 fixed project, and $225 on-demand hours changes margin fast. The lean case sits on the line, the base case builds a cushion, and the full-utilization case widens it if revisions and staffing stay controlled.

Planning case only; actual break-even shifts with win rate, revisions, and staffing mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean retainer mix	$694k	$208k	$486k	70.0%	$0k	Basically at break-even; one weak month can flip it.
Base Year 1 mix	$1,163k	$349k	$486k	70.0%	$328k	This gives a workable cushion if volume and revisions stay steady.
Full-utilization Year 2	$2,440k	$647k	$711k	73.5%	$1,082k	Higher load widens the cushion, but staffing and turnaround time still matter.

What breaks the break-even plan for a BIM clash detection service?

Stress test

The base plan clears break-even, but unpaid revisions, higher software and staffing overhead, and slower project starts can shrink the cushion fast. At $694k break-even revenue, margin pressure matters more than small price changes.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change; 30% variable expenses and $486k fixed costs.	$694k	$469k cushion	Healthy cushion, but overhead stays heavy.
Revenue shortfall	Revenue falls 20% to $930k.	$694k	$236k cushion	Less room for delays and slow project starts.
Fixed-cost increase	Fixed costs rise 15% to $559k.	$799k	$364k cushion	Overhead creep pushes break-even higher.
Margin pressure	Variable expenses rise to 38%, cutting contribution margin to 62%.	$784k	$379k cushion	Unpaid revision cycles eat margin fast.
Combined pressure	Revenue falls 30%, variable load rises to 38%, and fixed costs rise 15%.	$902k	$88k gap	A weak quarter can turn into a cash squeeze.

Can this clash detection service carry office space and hires before Month 5 break-even?

Founder checklist

Do not add office space, software seats, or more coordinators until signed pipeline, pricing, and delivery flow can carry the model’s Month 5 break-even. The first-year plan shows $1.395M revenue and $332K EBITDA, but only if CAC and fixed costs stay inside plan.

1Pipeline$694K/mo

Validate that late-stage work can really reach this level before you expand the team or lease more space.

2Fixed Load$51.5K/mo

Check the full monthly burn from rent, software, insurance, utilities, IT, and base payroll before you commit to more fixed cost.

3CM70%

Contribution margin (CM) stays strong only if freelance support, cloud spend, commissions, and travel hold near the modeled rates.

4Utilization24 hrs

Delay the $95K senior coordinator or $75K VDC engineer until delivery stays busy enough to support 24 billable hours per active customer.

5Cash Buffer$780K

Keep this reserve intact because the cash low point lands in Month 2, well before the model reaches break-even in Month 5.

6CAC$1.5K

Keep acquisition cost near the model and watch weekly lead flow against the $45K first-year marketing budget so break-even does not slip.
