Cost classification

This model reaches break-even in Month 5, but only if fixed payroll and rent are not treated like usage costs. Classifying each line correctly keeps the sales target tied to real cash commitments and revenue-linked fees.

Expense	Cost	Break-Even Treatment	Common Mistake
CEO salary	Fixed	Treat the $150,000 annual salary as a $12,500 monthly payroll commitment from Month 1.	Leaving founder pay out of break-even because cash is tight.
Senior QA Engineer payroll	Semi-fixed	Model Year 1 at 2.0 FTE and $125,000 per FTE, then add payroll in hiring steps as delivery capacity grows.	Reading 2.0 FTE as 20 FTE or modeling engineers as fully variable by project hour.
Automation Specialist payroll	Semi-fixed	Use $135,000 per FTE and step capacity from 1.0 FTE in the first year to 7.0 FTE in the mature year.	Spreading automation payroll evenly across every test hour.
Office Rent	Fixed	Include $6,500 monthly from Month 1 through Month 60 before calculating contribution margin coverage.	Typing $65,000 monthly, which adds $58,500 of false monthly overhead.
Professional Liability Insurance	Fixed	Carry $1,200 monthly as recurring overhead, separate from revenue-linked delivery expenses.	Using $12,000 monthly instead of the $1,200 monthly amount in the model.
Cloud Device Farm & Automation Licenses	Variable	Apply 12% of Year 1 revenue as a revenue-linked delivery expense.	Treating tool usage as a flat software bill when the model ties it to revenue.
Sales Commissions	Variable	Subtract 5% of revenue before measuring contribution toward fixed overhead.	Counting gross bookings as available cash before commissions are paid.
Recruitment & Job Board Fees	Semi-variable	Use the $1,500 monthly base, then scenario-test increases when hiring pace accelerates.	Typing $15,000 monthly or adding contractor tester spend without a real quote.

How does break-even shift from a lean launch to a fuller build?

Scenario table

More automation and a retainer-heavy mix lift contribution margin, but each staffing step-up also raises fixed cost. So break-even gets safer with scale, yet the monthly revenue floor climbs too.

Planning assumptions only; actual break-even will move with client mix, staffing timing, and utilization.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch: Year 1 mix	$178K	$43K	$91K	76%	$44K	Month 5 break-even; the monthly floor is about $120K.
Base case: Year 2 mix	$398K	$87K	$146K	78%	$165K	At about $187K a month, break-even is easier to clear.
Full launch: Year 5 mix	$1.43M	$243K	$377K	83%	$809K	Automation lowers variable load, but payroll step-ups raise the floor to about $454K a month.

What breaks the break-even plan if clients start late or costs run hot?

Stress test

Year 1 clears break-even at about $1,082K, with roughly $1,049K of cushion against $2,131K revenue. The weak spots are late client starts, higher Year 2 headcount, and margin drift from tool, hosting, or travel spend.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1,082K	$1,049K cushion	Year 1 revenue clears break-even, but the buffer is finite.
Revenue shortfall	One Year 1 client starts one month late.	$1,215K	$916K cushion	Slow starts can remove about $101K of contribution.
Fixed-cost pressure	Year 2 headcount and marketing lift fixed costs to $1,269K.	$1,626K	$505K cushion	More staff means revenue has to ramp faster.
Margin pressure	Cloud device farm, hosting, and travel keep margin at 76%.	$1,670K	$461K cushion	Small cost creep makes the same sales base work harder.
Combined pressure	A late client and Year 2 cost step-up hit together.	$1,803K	$328K cushion	Two small hits stack into a much thinner buffer.

Is this end-to-end testing service ready to lock payroll, tooling, and sales spend before break-even?

Founder checklist

Before you lock payroll and sales spend, make sure the first-year revenue path can reach $2.131M, the model can hold $733K of minimum cash through Month 5, and the pricing and capacity assumptions still work. If one of those slips, break-even pushes out fast.

1Revenue Path$2.131M Y1

Verify pipeline math can reach Year 1 revenue of $2.131M, because the model only breaks even in Month 5.

2Fixed Load$72.3K/mo

Check that payroll and overhead can carry this monthly fixed load at launch, since the team is in place before scale.

3Pricing76% CM

Confirm the 12% device and automation license load, 5% hosting, 5% sales commissions, and 2% travel still leave about 76% contribution margin.

4Billable Load140 hrs/customer/mo

Test that each active customer can absorb 140 billable hours a month, or revenue per account will fall short of the plan.

5Cash Cushion$733K

Keep at least the $733K minimum cash cushion through Month 5, because that is the low point before breakeven.

6Launch Spend$4.5K CAC

Test the $4.5K customer acquisition cost against the $120K Year 1 marketing budget and stage the $25K workstations, $12K network setup, $20K mobile device library, and $18K website build before sales ramp.
