Cost classification

Break-even is only useful if stable overhead stays separate from usage-linked spend. Keep payroll, rent, audits, and insurance in overhead; model cloud, storage, commissions, and onboarding with volume, and keep the $500,000 early capital spend out of monthly overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
CEO and Strategy Lead payroll	Fixed	Include the $180,000 annual salary as steady monthly overhead during the planning range.	Treating executive pay as if it rises with each customer.
Core engineering payroll	Fixed	Include the Chief Technology Officer and approved engineering team in fixed overhead for each staffing plan.	Putting engineering salaries into per-transaction delivery expense.
Office Rent and Utilities	Fixed	Use the $12,000 monthly amount in operating overhead from Month 1 through Month 60.	Reducing rent when short-term revenue dips.
SOC 2 and HIPAA Compliance Audits	Fixed	Include the $4,500 monthly compliance audit spend as fixed overhead.	Modeling required audit spend as optional after launch.
Cloud Computing and Real Time Processing	Variable	Model as a revenue-linked expense: 10.0% in the first year, falling to 6.5% by the fifth year.	Using one flat dollar amount while enterprise transaction volume grows.
Data Storage and Security Compliance Monitoring	Variable	Model as a revenue-linked expense: 4.0% in the first year, falling to 2.0% by the fifth year.	Ignoring storage growth as retained security data expands.
Sales Commissions and Partner Rebates	Variable	Apply 5.0% of revenue across all five years in the break-even model.	Counting commissions as fixed payroll instead of sales-linked spend.
Customer Success Representative headcount	Semi-fixed	Add in steps: 0.0 FTE in the first year, 1.0 FTE in the second year, and 5.0 FTE by the fifth year.	Spreading future hires evenly across all months from launch.

How does break-even shift from a lean pilot mix to a base enterprise mix and a full-scale case?

Scenario table

Break-even gets easier as paid conversion, enterprise share, implementation fees, and transaction volume rise. The lean case stays underwater, the base case reaches break-even around Month 24, and the full case builds a real cushion.

Planning assumptions only; actual results can move with sales mix, support load, and timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean pilot-heavy mix	$66.5k	$15.3k	$112.7k	77%	-$876k	Still below break-even; the pilot mix can’t cover fixed load.
Base enterprise mix	$191.1k	$40.1k	$162.7k	79%	-$399k	Break-even lands around Month 24 as enterprise share improves.
Full scale mix	$406.6k	$77.3k	$209.3k	81%	$1,053k	Clear cushion once volume, fees, and enterprise revenue stack up.

What pressures break-even first for this service?

Stress test

The biggest break-even risks are slower trial-to-paid conversion, higher cloud and compliance spend, and enterprise sales delays. If revenue slips to about $162k a month while fixed or support costs rise, the cushion disappears fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$191k	$0 cushion	Break-even holds at the Year 2 revenue run rate.
Revenue down	Monthly revenue runs 15% below the Year 2 average, to about $162k.	$191k	$29k gap	Slower trial-to-paid conversion can push the plan below break-even.
Fixed costs up	Year 2 fixed monthly costs rise 10%, to about $1.79M a year.	$189k	$2k cushion	Payroll and compliance growth can erase a very thin buffer.
Margin pressure	Variable expenses rise from 21% to 26%, cutting contribution margin from 79% to 74%.	$220k	$29k gap	Higher cloud processing or support spend lifts the revenue bar fast.
Combined pressure	Revenue falls to about $162k while fixed costs and variable expenses stay stressed.	$221k	$59k gap	Trial slowdown, compliance creep, and sales delays create a clear cash gap.

What should a founder verify before locking in this behavioral biometrics security build?

Founder checklist

Don’t lock in the build yet. First prove that trials, paid conversion, CAC, and support capacity can carry the $28.5K monthly fixed load and the $500K opening capex before Year 1 hiring goes beyond the core team.

1Launch Demand5.0%

Verify that at least 5.0% of prospects start a free trial, because weak launch demand makes the platform build and sales spend too heavy too soon.

2Paid CAC$1.5K CAC

Verify closed paid accounts stay near $1,500 CAC before you raise the $120K Year 1 marketing budget, or paid growth will outpace cash payback.

3Fixed Load$28.5K/mo

Verify fixed overhead stays at about $28.5K per month across rent, audits, insurance, legal, tools, and training, because higher lease or audit spend pushes break-even out.

4Margin77% CM

Verify Year 1 cloud, storage, commissions, and onboarding costs still leave about 77% contribution margin, since that margin decides whether each new account adds cash.

5Capacity Ramp50K→100K tx

Verify onboarding and security operations can scale with enterprise transaction volume from 50,000 in Year 1 to 100,000 in Year 5 before selling more Professional and Enterprise implementations.

6Cash Cushion$901K / M26

Verify you can fund the $500K early capex and still survive the Month 26 cash trough, because the model turns the corner after the break-even window, not before it.
