Cost classification

Break-even only works if fixed overhead, revenue-linked delivery spend, and staffing steps are kept separate. Here’s the quick math: fixed overhead is $5,450/month, before payroll and demand-driven fees.

Expense	Cost	Break-Even Treatment	Common Mistake
Recurring office overhead	Fixed	Include office rent, utilities, business insurance, website hosting, office supplies, professional services, and general software subscriptions at $5,450/month.	Spreading stable overhead across jobs and making margin look worse than it is.
Founder, senior writer, and sales salaries	Semi-fixed	Model payroll in steps as full-time equivalent staffing changes, not as a percent of revenue.	Treating payroll like it flexes smoothly with every new project.
Specialized authoring software licenses	Semi-variable	Use 5.0% of revenue in the first year, falling to 3.0% by the mature year.	Booking it as fixed software and hiding usage pressure as volume grows.
AI assistant tool usage fees	Semi-variable	Use 3.0% of revenue in the first year, falling to 2.0% by the mature year.	Assuming tool usage is free once the subscription is active.
Sales commissions	Variable	Apply 8.0% of revenue in the first year, stepping down to 6.0% by the mature year.	Putting commissions below the line and overstating contribution margin.
Project-specific subcontractor fees	Variable	Apply 7.0% of revenue in the first year, stepping down to 5.0% by the mature year.	Treating subcontractors like fixed staff before demand is proven.
Annual marketing budget	Semi-fixed	Plan it as a budget step: $15,000 in the first year, rising to $80,000 by the mature year.	Modeling marketing as a clean percent of sales when spend is planned in blocks.

How does break-even change across lean, base, and full technical writing scenarios?

Scenario table

Lean and base sit below break-even, while full capacity finally clears it because higher price mix and utilization lift the contribution margin faster than fixed payroll grows. Retainer-heavy work helps, but only if utilization stays high.

Planning-case figures are directional, not guarantees; pricing, mix, and utilization can move them fast.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean Year 1 project-heavy mix	$84K	$19K	$244K	77.0%	-$179K	Far below break-even, so cash burn stays high.
Base Year 3 balanced mix	$557K	$109K	$536K	80.5%	-$88K	Still below break-even; the gap narrows, but fixed costs still outrun margin.
Full Year 4 retainer-heavy mix	$1.17M	$207K	$686K	82.3%	$275K	Clears break-even with cushion, but utilization has to stay strong.

What breaks the Year 1 break-even plan for a technical writing service?

Stress test

Base Year 1 breaks even at about $317K a month, with $244K of fixed cost and 23% variable expense. If bookings slip, overhead grows, or delivery costs rise, the cushion disappears fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$317K	$0 gap	No cushion if revenue lands here.
Revenue shortfall	Monthly revenue lands 15% below break-even, near $269K.	$317K	$37K gap	A small top-line slip becomes a monthly loss.
Fixed-cost rise	Fixed costs rise 10% from $244K to about $268K.	$349K	$32K gap	Overhead growth pushes the target up fast.
Margin pressure	Variable expenses rise from 23% to 28%.	$339K	$22K gap	Higher delivery cost means more billable work to cover overhead.
Combined pressure	Revenue falls 15%, variable expenses rise to 28%, and fixed costs rise 10%.	$373K	$75K gap	Three-way pressure turns break-even into a deep monthly loss.

Founder checklist

Only scale fixed costs once you can prove the $317K/month revenue path, the Year 1 pricing, and the delivery flow behind it. If the pipeline or renewals slip, the $23.2K/month fixed load will outrun break-even.

1Demand proof$317K/mo

Verify the pipeline can support a $317K/month revenue path and the Year 1 mix of 60% project documentation, 30% API documentation, and 10% retainers before you lock in payroll.

2Price floor$110/$125/$105

Hold Year 1 rates at $110/hour for project documentation, $125/hour for API documentation, and $105/hour for retainer services so the model is not built on discount work.

3Fixed load$23.2K/mo

This is the Year 1 fixed monthly load from office rent, utilities, software, professional services, insurance, hosting, supplies, and payroll, so test demand before you commit to the space.

4Margin buffer77% CM

Contribution margin (CM, money left after variable costs) is about 77% after software, AI, sales commissions, and subcontractor fees, so keep outsourced work from rising too far.

5Capacity ramp2.0 FTE

Year 1 staffing is 2.0 full-time equivalents across the founder, a half-time senior writer, and a half-time sales lead, with the next hires not starting until Month 13.

6Launch buffer$223K

Keep the $223K minimum cash cushion while you test demand against the $47.5K launch capex and the $1.8K Year 1 CAC, because weak early pipeline will hit this balance first.
