Which software distribution expenses are fixed, and which move with sales?

Cost classification

Break-even only works if each expense follows its real driver. Put revenue-linked fees in contribution margin, keep stable monthly overhead separate, and treat payroll as step capacity.

Expense	Cost	Break-Even Treatment	Common Mistake
Vendor License Fees	Variable	Deduct 5.0% of first-year revenue before overhead coverage.	Treating vendor fees like monthly overhead.
Payment Processing Fees	Variable	Deduct 2.5% of first-year revenue from gross sales.	Ignoring fee drag on contribution margin.
Digital Advertising Spend	Variable	Use 10.0% of first-year revenue as sales-linked demand spend.	Mixing CAC and contribution margin without a rule.
Customer Success Tools	Variable	Deduct 2.0% of first-year revenue for support tooling.	Assuming customer support is free.
Cloud Hosting & Infrastructure	Fixed	Include $3,500 per month in overhead coverage.	Tying base hosting to each license sold.
Payroll	Semi-fixed	Model the $270,000 first-year wage base as capacity added in steps.	Hiring ahead of revenue proof.
Office, Software Tools, and Admin Overhead	Fixed	Include $6,600 per month for tools, rent, utilities, legal, accounting, and admin.	Burying rent and admin in variable expenses.

How does break-even change from a lean launch to a fuller team?

Scenario table

Break-even climbs as fixed payroll grows, even when the fuller case has a better margin. The lean setup breaks even near $36.4k a month, while the fuller setup needs about $57.8k, so staffing is the main risk.

Planning cases only; actual results will move with mix, pricing, CAC, and hiring timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$36,398	$7,098	$29,300	80.5%	$0	Lowest revenue floor; best for pre-scale catalog testing.
Base case	$40,497	$7,897	$32,600	80.5%	$0	Midpoint case; payroll raises the floor, so volume still matters.
Fuller Year 2 case	$57,767	$10,167	$47,600	82.4%	$0	Higher margin helps, but the larger team pushes break-even up fast.

What breaks the break-even plan for software distribution?

Stress test

This plan is most exposed to sales misses and margin squeeze. A 10% revenue dip, a 10% overhead jump, or a 5-point fee increase each pushes break-even above the base case, so vendor terms and paid acquisition need tight control.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change from the base case.	$40,500	$0 gap	Break-even is met only if pricing and mix hold.
Revenue shortfall	Monthly revenue slips 10% to about $36,500.	$40,500	$3,300 gap	A small sales miss quickly eats the cushion.
Fixed-cost pressure	Overhead rises 10% from the base plan.	$44,600	$4,100 gap	Rent, staffing, or tools creep can push break-even out of reach.
Margin pressure	Variable expenses rise to 24.5%, cutting margin to 75.5%.	$43,200	$2,700 gap	Higher vendor fees or chargebacks hit every sale.
Combined pressure	Revenue falls 10%, overhead rises 10%, and variable expenses rise 5 points.	$44,600	$8,400 gap	Three small hits together create a fast cash drain.

Should you lock the platform build and reseller terms yet?

Founder checklist

Don't lock the platform build or reseller terms until the Year 1 demand and cost assumptions hold in live tests. The model needs about $40,500 in monthly revenue to break even, and cash bottoms near $559,000 in Month 13.

1Demand Proof$100K

Verify real demand before you push past the Year 1 marketing budget, because paid spend without traction will not support break-even.

2Fee Terms7.5%

Lock vendor license and payment processing terms first, since the Year 1 direct fee stack starts at 7.5% and protects gross margin.

3Order Value$145.20

Test pricing and product mix on live orders, because the Year 1 average order value is about $145.20 and small mix shifts change revenue fast.

4CAC Test$55

Run paid channels until customer acquisition cost holds near the Year 1 assumption, or the marketing ramp will outrun payback.

5Payroll Ramp$40.5K/mo

Delay support hiring until monthly revenue clears the break-even line, so fixed payroll does not rise before the model can carry it.

6Cash Buffer$559K

Protect cash through Month 13, because the model bottoms near $559,000 and Month 14 break-even is a target, not a guarantee.
