Cost classification

Break-even is reliable only when fixed overhead stays separate from project delivery expense. If contractor payouts, review fees, or revision overruns sit in overhead, the model understates the revenue needed to cover each new client.

Expense	Cost	Break-Even Treatment	Common Mistake
Co-working Space Membership	Fixed	Include $2,500 per month in baseline overhead before calculating required gross profit.	Allocating it to projects and making margins look weaker than they are.
Enterprise Authoring Tools Subscription	Fixed	Include $1,200 per month as recurring operating overhead for the full planning range.	Treating the subscription as usage-based when it does not move with client volume.
Contractor Technical Writer Fees	Variable	Deduct 18.0% of first-year revenue before contribution margin; this falls to 16.0% by the mature year.	Putting contractor payouts in overhead and overstating contribution margin.
Subject Matter Expert Review Fees	Variable	Deduct 4.0% of first-year revenue as a delivery expense tied to project work.	Ignoring review time until quality issues force rework.
Project Specific Software Licenses	Variable	Deduct 3.5% of first-year revenue because project needs drive the spend.	Bundling it with fixed software and missing the per-project drag.
Referral and Partner Commissions	Variable	Deduct 5.0% of first-year revenue when partner-sourced work closes.	Counting referred revenue at full margin before paying commissions.
Revision Labor Beyond Included Scope	Semi-variable	Keep base delivery hours in project margin, then add extra labor when revisions exceed scope.	Treating overruns as overhead instead of pricing or change-order work.
Added Editor or Project Manager Capacity	Semi-fixed	Add payroll in steps when workload rises, such as the Lead Editor starting after the first year.	Assuming staffing scales smoothly by revenue instead of hiring in chunks.

How does break-even change from a lean launch to full-capacity delivery?

Scenario table

Break-even rises as the mix shifts toward higher-margin API and compliance work, while payroll steps up too. CM ratio improves from 69.5% in the lean launch to 76.5% at full capacity, so the monthly break-even bar and profit cushion both move.

Planning assumptions only; project mix, revision load, and client churn can move break-even fast.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$84k	$26k	$40k	69.5%	$18k	Clears break-even, but the cushion is still tight.
Base growth	$170k	$49k	$54k	71.3%	$67k	Healthy cushion; staffing and close rates matter more.
Full-capacity documentation	$572k	$134k	$77k	76.5%	$360k	Strong cushion, but revision-heavy work can still compress margin.

What could push this user manual writing service below break-even?

Stress test

Base Year 1 still covers overhead, but the cushion shrinks fast if sales slow or contractor costs rise. The combined downside is the real stress point: a 20% revenue drop plus a 5-point margin hit leaves almost no room.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change in Year 1 revenue or cost mix.	$46.4K/month	$37.6K cushion	Solid buffer, but underbooked months still matter.
Revenue shortfall	Revenue drops 20% while costs stay flat.	$46.4K/month	$20.7K cushion	A slower close rate cuts the cushion fast.
Fixed-cost pressure	Fixed overhead rises by $10K per month.	$60.8K/month	$23.1K cushion	Extra tools or headcount push break-even up.
Margin pressure	Variable expense rate rises to 35.5% of revenue.	$49.9K/month	$33.9K cushion	Higher contractor fees or more revisions eat margin.
Combined pressure	Revenue drops 20%, variable expense rate rises to 35.5%, and fixed overhead rises by $10K per month.	$65.4K/month	$1.7K cushion	Sales and cost pressure together nearly erase the buffer.

Should you add the Lead Editor before this user manual writing service proves break-even?

Founder checklist

Not yet, unless pricing, pipeline, and cash all clear the model first. Break-even lands in Month 6, but the business still needs about $819K of minimum cash in Month 2, so the next hire should wait until those gates are real.

1Pricing floor695% CM

Lock revision limits in proposals so the Year 1 contribution margin holds before you add headcount or software.

2Project values$5.0K-$6.6K

Verify signed work lands near the assumed average values for software docs, hardware manuals, API docs, and compliance audits.

3Base burn$32.2K/mo

Keep the monthly fixed load near this level, because rent, tools, insurance, legal, CRM, and Year 1 wages must clear before break-even.

4Capacity bench42.0 hrs

Keep active-customer load near 42 billable hours a month and keep contractor coverage ready before you take overlapping manuals.

5Cash floor$819K, Month 2

Protect the Month 2 cash trough, because the model needs about this much on hand before the ramp is safe.

6Launch pipeline$45K / $1.5K CAC

Build pipeline before the Year 1 marketing budget is spent and keep CAC near $1,500 so Month 6 stays a planning marker.
