Which port management service expenses stay fixed, and which move with sales?

Cost classification

Break-even is reliable only when committed overhead and revenue-linked expenses are separated. In this model, fixed payroll and rent set the floor, while data fees and cloud usage reduce contribution as revenue grows.

Expense	Cost	Break-Even Treatment	Common Mistake
CEO, CTO, sales, software, data science, and logistics operations salaries	Fixed	Include committed payroll in monthly overhead; first-year salaries total about $106,667 per month.	Treating signed payroll as per-client labor.
Office rent	Fixed	Add $15,000 per month to the break-even floor from Month 1 through Month 60.	Leasing space before signed demand supports it.
Cybersecurity compliance	Fixed	Include $6,500 per month as recurring overhead needed to operate the service.	Burying compliance inside general software spend.
Research and development software licenses	Fixed	Add $5,000 per month as the base platform operating spend.	Calling recurring licenses a one-time setup item.
Annual marketing budget	Semi-fixed	Model the first-year budget at $250,000, then step it up by year as planned.	Treating customer acquisition cost as the cash bill.
Administrative and office supplies	Semi-variable	Start with the $2,500 monthly base, then watch for increases as headcount rises.	Ignoring supply spend as the team scales.
Data acquisition fees	Variable	Apply as a revenue-linked charge, starting at 4.0% of revenue in the first year.	Classifying data fees as fixed overhead.
Cloud hosting and processing	Variable	Apply as usage-linked spend, starting at 5.0% of revenue in the first year.	Assuming hosting stays flat forever.

How does break-even move from lean launch to base case and full capacity for a port management service?

Scenario table

As revenue scales, the variable take on each dollar stays low, but fixed staffing and office costs rise fast. That means lean launch stays loss-making, base case nears break-even, and full capacity is where the model turns clearly profitable.

Planning cases only; these figures are model assumptions, not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$120k	$11k	$187k	91%	-$78k	Losses are still wide, so this stage proves demand.
Base case	$303k	$24k	$302k	92%	-$23k	Month 20 is the first break-even signal, but annual EBITDA stays negative.
Full capacity	$585k	$41k	$451k	93%	$93k	This is the first clear profit cushion after staffing and coverage mature.

What breaks the break-even plan if revenue slips or costs creep up?

Stress test

The base case clears break-even at about $188k a month, but the cushion is thin. A 10% revenue slip, higher fixed overhead, or 3-point margin pressure can push the plan back into loss fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$188k/mo	$0 gap	Break-even lands around Month 20.
Revenue shortfall	Revenue comes in 10% below the break-even run rate.	$188k/mo	$169k gap	A small sales miss leaves a large monthly operating hole.
Fixed-cost increase	Fixed overhead rises 10% to $1,878k.	$206k/mo	$18k gap	Wage, rent, or compliance creep pushes breakeven higher.
Margin pressure	Variable expense rises from 9% to 12%, cutting margin to 88%.	$194k/mo	$6k gap	Higher data, cloud, or support costs eat the cushion.
Combined pressure	Revenue runs 10% below plan and variable expense rises to 12%.	$194k/mo	$389k gap	Two misses together turn a small gap into a big loss.

What should a port management founder verify before signing long-term overhead?

Founder checklist

Verify signed monthly retainers, staffing, and cash before you lock in rent or hire up. The model does not break even until Month 20, and it bottoms at -$774K in Month 28, so the commitment should wait for proof of demand and operating control.

1Signed Retainers$188K/mo

Confirm signed monthly retainers are close to the $188K break-even test mix before you add fixed staff and tech.

2Lease Gate$15K/mo

Keep the $15K monthly office rent off the books until port access and on-site needs clearly justify it.

3Margin Check91% CM

Verify Year 1 still holds about 91% contribution margin after 4.0% data fees and 5.0% cloud hosting.

4Staff Ramp$106.7K/mo

Hire against utilization, not hope, because Year 1 payroll runs about $106.7K a month across 8.0 FTE.

5Cash Floor-$774K

Treat the -$774K minimum cash in Month 28 as a hard warning and delay more spend if onboarding slips.

6Launch Spend$570K

Stage the $250K Year 1 marketing plan separately from customer acquisition cost (CAC) and the $320K server, fit-out, security, workstation, and connectivity spend.
