Which expenses are fixed, variable, or semi-fixed for this transportation management system?

Cost classification

Bad classification makes break-even look earlier than it is. In this model, Month 4 break-even depends on keeping fixed overhead separate from revenue-linked cloud, API, commission, and support costs.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Use $3,000 per month in the fixed overhead base from Month 1 through Month 60.	Tying rent to revenue and understating the cash needed before scale.
Legal & Accounting Retainer	Fixed	Use $1,500 per month as recurring fixed overhead for break-even math.	Treating the retainer as one-time setup work instead of a monthly run-rate expense.
CEO Salary	Fixed	Use $150,000 per year as fixed payroll in the first year and later years.	Excluding founder payroll, which makes break-even look cleaner than payroll reality.
Lead Software Engineer Salary	Fixed	Use $120,000 per year as fixed technical payroll starting in Month 1.	Moving core engineering into variable expense even though it does not rise per customer.
Later Hiring Roles	Semi-fixed	Treat Sales Manager, Marketing Specialist, Customer Success Manager, and Junior Software Engineer hiring as step increases when roles start in later model years.	Smoothing new hires evenly across revenue instead of adding payroll when capacity is hired.
Annual Marketing Budget	Semi-fixed	Use $150,000 in the first year as a planned spending level, then step it up with the annual budget.	Modeling marketing as pure variable CAC even when the budget is committed upfront.
Cloud Hosting & Data Services	Variable	Use 8.0% of revenue in the first year, declining by year as stated in the model.	Putting hosting in fixed overhead and missing margin drag as usage grows.
Sales Commissions & Payment Processing	Variable	Use 5.0% of revenue in the first year because the expense moves with paid sales volume.	Forgetting commissions and processing fees when calculating contribution margin.

How does break-even shift across lean, base, and full TMS plans?

Scenario table

As the mix shifts toward Pro and Enterprise, margin improves faster than fixed overhead. That gives the base and full paths more cushion, even though the cost base climbs.

Planning assumptions only; actual break-even will move with sales mix, onboarding speed, and fixed cost control.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch path	$519K	$104K	$415K	80%	$664K	Month 4 break-even leaves little room for slip.
Base growth path	$1.14M	$171K	$969K	85%	$6.3M	Higher Pro and Enterprise share gives a wider cushion.
Full scale path	$1.80M	$180K	$1.62M	90%	$25.3M	Enterprise-heavy mix gives the strongest break-even buffer.

What breaks the TMS break-even plan?

Stress test

The plan is most exposed to sales slippage and cost creep. Year 1 break-even sits near $519K, so a 10% revenue miss or a 25% variable-cost rise can push it below break-even fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	Year 1 base case holds fixed costs at $415K and variable expenses at 20%.	$519K	$0 gap	Base case reaches break-even in Month 4.
Revenue shortfall	Revenue falls 10% to $467K.	$519K	$52K gap	A small demand miss creates a fast funding gap.
Fixed-cost pressure	Fixed spend rises 10% to $457K.	$571K	$52K gap	Hiring, software, or office creep pushes break-even higher.
Margin pressure	Variable expenses rise to 25%, cutting contribution margin to 75%.	$553K	$34K gap	Cloud, support, and payment costs eat margin quickly.
Combined pressure	Revenue falls to $467K while fixed spend rises to $457K and variable expenses hit 25%.	$609K	$142K gap	Watch delayed onboarding, cloud overruns, integration creep, discounting pressure, and support tickets outpacing subscriptions.

What should the founder verify before committing to major Transportation Management System hiring and platform spend?

Founder checklist

Before you add headcount or heavy build spend, prove Month 4 break-even is real, not just modeled. The plan only works if the Year 1 pipeline, 80% contribution margin, and cash cushion all hold at once.

1Demand proof220 actives

Verify the Year 1 pipeline can support about 220 active customers and a blended recurring revenue rate near $235.90 per customer per month.

2Fixed load$49.8K/mo

Check that the business can carry the post-hire fixed load once Month 13 roles start, because that is the real step-up before sales gets easier.

3Margin guard80% CM

Keep cloud hosting at 8%, integrations at 4%, commissions and processing at 5%, and support at 3% so contribution stays near 80%.

4Hire gateMonth 13

Do not add the Sales Manager, Marketing Specialist, or Junior Software Engineer until the trial-to-paid path and sales cycle are clear.

5Cash floor$849K

Keep the modeled minimum cash in view, with the low point in Month 2, so early build spend does not outrun the reserve.

6Launch capex$77K

Fund the full launch setup for tools, equipment, design, IP, collateral, security, and hardware before go-live so the build is not cut short.
