Which expenses are fixed, variable, semi-variable, or semi-fixed for this customer service software break-even model?

Cost classification

Break-even lands in Month 9 only if the model treats usage and sales costs correctly. Hosting, commissions, ads, and support capacity move differently than rent or core salaries, so don’t flatten them into fixed overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
CEO salary, $120,000/year	Fixed	Include as recurring monthly overhead of $10,000 across the planning range.	Cutting founder pay from break-even and overstating profit.
Lead Software Engineer salary, $150,000/year	Fixed	Include as recurring monthly product overhead of $12,500 from Month 1.	Treating core engineering as optional until revenue scales.
Office Rent, $3,000/month	Fixed	Include the full $3,000 each month regardless of customer count.	Spreading rent per customer and making early margins look worse.
Internal Software Subscriptions, $1,500/month	Fixed	Hold at $1,500 per month unless the operating plan adds seats or tools.	Using $15,000/month instead of the model’s $1,500/month assumption.
Sales Commissions & Bonuses, 7.0% of first-year revenue	Variable	Apply as a revenue-linked deduction, falling to 5.0% by the fifth year.	Treating commissions as fixed payroll and missing margin drag.
Digital Advertising Spend, 5.0% of first-year revenue	Variable	Model as revenue-linked selling spend, falling to 3.0% by the fifth year.	Mixing it with the separate annual marketing budget and double counting.
Cloud Infrastructure & Hosting, 5.0% of first-year revenue	Variable	Deduct with revenue as usage grows, improving to 3.0% by the fifth year.	Treating hosting as fully fixed and overstating contribution margin.
Customer Success Manager capacity, starts Month 25 at $65,000/year	Semi-fixed	Add in a staffing step when customer volume needs dedicated success coverage.	Treating support labor as fully fixed before workload exists.

How does break-even shift from lean founder-led proof to base hiring and full scale support?

Scenario table

Higher fixed costs push break-even up, even when the contribution margin improves. So the lean plan needs the least revenue, while the full plan only works if scale stays steady.

Scenario figures are planning assumptions for break-even analysis, not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean founder-led proof	$539k	$108k	$431k	80%	$0	Lowest revenue bar, so it is the safest start.
Base hiring plan	$987k	$181k	$806k	81.7%	$0	Break-even is higher, but the model supports added team capacity.
Full scaled sales and support	$1,419k	$234k	$1,185k	83.5%	$0	Best only if pipeline and support load stay consistent.

What breaks the break-even plan for this customer service software business?

Stress test

Year 1 breaks first, because the model needs about $539k MRR against $431k of fixed costs at an 80% contribution margin. Weak trial conversion, discounting, higher cloud use, support-ticket surges, or early hiring can push it out of balance fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$539k MRR	$0 cushion	At plan, revenue just covers fixed costs.
Revenue shortfall	Monthly revenue slips to $431k MRR.	$539k MRR	$86k gap	Weak trial conversion leaves about an $86k monthly operating gap.
Fixed-cost pressure	Fixed costs rise by $10k per month.	$664k MRR	$125k gap	Early hiring or overhead pushes the break-even bar much higher.
Margin pressure	Contribution margin falls from 80% to 75%.	$575k MRR	$36k gap	Discounting, cloud use, or ticket surges cut the cushion fast.
Combined pressure	Revenue holds at $431k MRR, margin falls to 75%, and fixed costs rise to $531k.	$708k MRR	$277k gap	Two hits at once create about a $208k monthly loss.

Should you scale payroll and paid acquisition before this software is actually break-even ready?

Founder checklist

Before you add payroll or heavier marketing, confirm the model clears break-even with the Year 1 prices, funnel, and CAC already in hand. If you can’t hold about 80% contribution margin and keep cash near $735K through Month 8, the Month 9 break-even case is too tight.

1Price mix$49 / $149 / $499

Verify buyers will take the Starter, Pro, and Enterprise prices before you spend harder, because the mix drives revenue per account and the path to break-even.

2Funnel proof3.0% / 15.0%

Verify Year 1 traffic can turn at 3.0% from visitor to trial and 15.0% from trial to paid, since the launch forecast depends on that funnel.

3CAC$250 CAC

Verify customer acquisition cost can stay near $250, because every step above that pushes payback farther out and makes paid growth less safe.

4Contribution80% CM

Verify Year 1 direct costs stay near 20% of revenue, which leaves about 80% contribution margin to cover payroll, rent, and marketing.

5Burn load$30.6K/mo

Verify monthly burn stays near $30.6K before adding the Month 13 Data Scientist, Sales Manager, and Marketing Specialist, and wait on the Month 25 Customer Success Manager until support demand justifies it.

6Cash reserve$735K / Month 8

Verify you can keep at least $735K of minimum cash and survive the Month 8 low point, so you do not lock in extra rent, tools, or workstations before the Month 9 break-even date.
