Which expenses are fixed, and which move with sales in supply chain automation?

Cost classification

Break-even is reliable only when fixed overhead stays separate from usage-driven spend. Here, revenue can clear Month 3 break-even, but cloud, API, commission, and support percentages still move with contract volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Use $5,000 per month from Month 1 through Month 60, regardless of contracts closed.	Letting rent scale with revenue instead of treating it as baseline overhead.
Software Licenses for G&A, CRM, and ERP	Fixed	Use $2,000 per month as operating overhead in the break-even base.	Missing admin systems because they don’t sit inside product delivery.
CEO, Lead Engineer, and Data Scientist Payroll	Semi-fixed	Model Year 1 payroll as staffed capacity: CEO $180,000, lead engineer $160,000, and data scientist $150,000 at 0.5 FTE.	Hiring ahead of recurring revenue before workload thresholds support it.
Cloud Infrastructure & Data Processing	Variable	Apply 7.0% of revenue in the first year, falling to 5.0% by Year 5.	Treating all hosting as fixed and hiding transaction-volume pressure.
Third-Party API Licenses & Integrations	Variable	Apply 3.0% of revenue in the first year, falling to 2.0% by Year 5.	Ignoring integration usage when customer workflows and transactions rise.
Sales Commissions & Bonuses	Variable	Apply 5.0% of revenue in the first year, falling to 3.0% by Year 5.	Forgetting commissions and overstating contribution margin.
Customer Onboarding & Support Services	Variable	Apply 2.0% of revenue in the first year, falling to 1.5% by Year 5.	Underpricing onboarding work as contract count grows.

How does break-even change across lean, base, and full adoption paths?

Scenario table

Lean sits well below the $738K break-even line, base lands on it, and full adds cushion. The gap mainly comes from active-customer volume, setup income, and the 17% variable cost load.

Planning cases only; actual break-even will move with sales pace, setup mix, and support load.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean pipeline case	$74K	$13K	$613K	83%	-$551K	Still far below break-even, so pre-sales risk stays high.
Base case	$739K	$126K	$613K	83%	$0	Hits the modeled Month 3 break-even point.
Full adoption case	$902K	$153K	$613K	83%	$136K	Creates a cushion, but hiring should wait for demand to hold.

What breaks the break-even plan for supply chain automation?

Stress test

The plan is most fragile on top-line misses and margin creep. With $613,000 in monthly fixed costs and 17% variable expense, break-even is about $738,554 a month, so slower onboarding, API overages, or weaker conversion can move the target fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$738,554	$0 gap	Base case reaches break-even by Month 3.
Revenue shortfall	Monthly revenue lands $10,000 below plan.	$738,554	$10,000 gap	A small miss leaves no cushion.
Fixed-cost pressure	Monthly overhead rises by $10,000.	$750,602	$12,048 gap	Fixed spend pushes break-even up fast.
Margin pressure	Variable expenses rise from 17% to 18% of revenue.	$747,561	$9,007 gap	One point of margin loss raises the bar.
Combined pressure	Monthly overhead rises by $10,000 and variable expenses rise to 18%.	$759,756	$21,202 gap	Small drifts together erase the cushion.

What should the founder verify before locking the build, hiring, and ramp-up spend?

Founder checklist

Don’t commit to the build and hiring plan until the first-year pipeline can support about 16 active customers and the cash plan still holds $816K at the Month 2 low point. The math only works if demand, onboarding, and vendor setup clear the break-even bar before spend accelerates.

1Pipeline Proof16 customers

Verify the pipeline can support about 16 active customers before setup fees, because that is the base load the break-even plan needs.

2Funnel Math2.0% / 15.0%

Check that Year 1 visitor-to-trial and trial-to-paid rates really hold there, or the launch funnel will miss the customer count you need.

3CAC Test$1.5K CAC

At a $150K marketing budget, that CAC implies about 100 acquired customers, so confirm the lead flow can absorb that spend.

4Fixed Load$48.8K/mo

Hold the first-year load near $48.8K a month and remember the $127K launch capex, because fixed spend plus upfront build is what makes or breaks the cash curve.

5Margin Check83% CM

Keep cloud, API, sales, and support costs in line with the 83% contribution margin, or every new customer will do less to cover fixed spend.

6Runway Gate$816K

Delay sales, customer success, and operations hires until after Year 1, and protect the $816K cash floor in Month 2, because early headcount can push break-even past Month 3.
