Cost classification

Break-even gets reliable only when payroll, rent, delivery fees, and usage-based tools sit in the right buckets. If contractor overruns or cloud testing usage are treated as fixed overhead, Month 8 break-even can look safer than it is.

Expense	Cost	Break-Even Treatment	Common Mistake
CEO / Founder salary	Fixed	Include as recurring monthly overhead across the planning range.	Excluding founder pay to make break-even look earlier.
Senior QA Engineer salary	Fixed	Treat the first-year role as base delivery capacity already committed.	Counting the salary as variable labor by project.
Office Rent	Fixed	Use $3,500 per month in fixed overhead from Month 1.	Spreading rent across billable hours and hiding idle capacity.
Sales Commissions & Bonuses	Variable	Apply 5% of revenue in the first year before contribution margin.	Budgeting commissions as a flat monthly sales expense.
Project-Specific Contractor Fees	Variable	Apply 4% of revenue in the first year as delivery volume grows.	Treating contractor overruns as fixed overhead instead of job-linked spend.
Cloud Infrastructure & Device Lab	Semi-variable	Model at 12% of revenue in the first year for usage-linked testing capacity.	Locking cloud testing usage into one flat monthly amount.
Specialized Testing Tool Licenses	Semi-variable	Model at 6% of revenue in the first year when tool use scales with work.	Treating all testing licenses like basic office software.
Junior QA Engineer salary	Semi-fixed	Add as a capacity step when the role starts in Year 2.	Smoothing new hires evenly across Month 1 through Month 60.

How does break-even change as the setup moves from lean to base to full?

Scenario table

More hiring, tool spend, and service depth push fixed costs up faster than margin improves, so the monthly revenue needed to stay even rises. The real test is whether anchor retainers can cover the bigger cost base before headcount grows.

Planning assumptions only; actual break-even will move with service mix, hiring pace, and sales quality.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch setup (Year 1)	$420k	$113k	$307k	73%	$0	Lowest hurdle, but a small sales miss cuts the cushion fast.
Base operating setup (Year 2)	$705k	$173k	$532k	75.5%	$0	This is the core case; steady anchor retainers keep it on track.
Full scale setup (Year 3)	$968k	$213k	$755k	78%	$0	Best margin, but it needs the biggest monthly revenue base.

What breaks the break-even plan if demand slows or costs move up?

Stress test

The plan breaks first on demand misses, then on staffing creep. If contractor fees or tool spend rise before recurring work is signed, break-even jumps and cash gets tight.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Base case. No change in demand, staffing, or delivery mix.	$468,000	$0 cushion	Base case clears with no spare room.
Revenue shortfall	Billable revenue lands 10% below plan.	$468,000	$47,000 gap	A small demand miss wipes out the cushion.
Fixed-cost increase	Year 2 staffing lands before recurring work scales.	$803,000	$335,000 gap	Hiring first pushes the hurdle much higher.
Margin pressure	Delivery burden rises from 27% to 29%.	$481,000	$13,000 gap	Slightly weaker margin leaves little room for slippage.
Combined pressure	Year 2 staffing lands and delivery burden rises to 29%.	$825,000	$357,000 gap	Two small drags together create a much bigger break-even gap.

What should a software testing founder verify before hiring full-time QA staff and locking in fixed costs?

Founder checklist

Don’t lock in full-time QA hires yet. Confirm anchor clients can support Year 1 pricing, keep CAC near $1,200, and cover the $816K cash need through Month 7; otherwise, the model stays fragile before the Month 8 break-even point.

1Anchor clientsMonth 8

Verify signed work or late-stage pipeline exists before full-time hiring, because Year 1 EBITDA is still negative and break-even does not land until Month 8.

2Price test$120/$90/$150/$160

Test that buyers accept the Year 1 hourly rates of $120 automated, $90 manual functional, $150 performance load, and $160 security testing before you add staff.

3CAC control$1,200

Track customer acquisition cost against the $1,200 Year 1 assumption as marketing rises from $25K to $50K, so growth does not outrun usable demand.

4Margin mix12% + 4%

Keep cloud infrastructure and device lab spend near 12% and contractor fees near 4% of revenue, because that is the cleanest check on delivery margin.

5Billable hours30/25/40/35 hrs

Match staffing to the Year 1 billable hours by line: 30 automated, 25 manual functional, 40 performance load, and 35 security, so each hire adds real throughput.

6Cash runway$816K / M7

Protect cash through Month 7, since minimum cash is $816K and the business only reaches breakeven in Month 8, with $5.9K of monthly fixed overhead already locked in.
