Cost classification

Break-even is only useful if fixed overhead, revenue-linked fees, and support capacity are split correctly. Here, the big risk is treating endpoint support like rent when ticket load rises with managed devices.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent & Utilities	Fixed	Use $4,500 per month from Month 1 through Month 60. It does not rise just because more devices are managed.	Scaling rent with customers or endpoints.
Software Licenses & Development Tools	Semi-fixed	Start with the $3,200 monthly base, then model step-ups only when tool tiers, seats, or capacity limits change.	Holding the tool stack flat forever.
Cloud Infrastructure & Hosting	Variable	Apply it as a revenue-linked delivery charge: 12.0% in Year 1, falling to 8.0% by Year 5.	Using one flat hosting dollar amount.
Payment Processing Fees	Variable	Tie fees directly to collected revenue: 3.2% in Year 1, easing to 2.5% by Year 5.	Ignoring fees in contribution margin.
Customer Success & Support Tools	Variable	Model as usage-linked support tooling: 2.5% of revenue in Year 1, declining to 1.5% by Year 5.	Treating support tooling like office software.
Customer Support Specialist Labor	Semi-variable	Include a staffing base, then scale with load: 0.3 FTE in Year 1 grows to 2.5 FTE in Year 5.	Treating support labor as fully fixed.
Annual Marketing Budget	Semi-fixed	Use the planned budget steps: $120,000 in Year 1, rising to $400,000 in Year 5 as acquisition scales.	Modeling marketing as a constant sales percentage.

How does break-even change across lean, base, and full MDM launch scenarios?

Scenario table

Lean clears break-even, but the cushion is thinnest. As the mix shifts toward Business and Enterprise, margin improves, yet fixed costs still set the floor, so support load and device density decide how safe the plan really is.

Planning assumptions only. Real break-even will move with device density, support load, and enterprise mix.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$1,470k	$260k	$563k	82.3%	$647k	Still above break-even, but the cushion is smaller.
Base launch	$2,050k	$294k	$1,006k	85.7%	$752k	Highlighted case with a solid cushion if mix holds.
Full launch	$2,720k	$326k	$1,177k	88.0%	$1,217k	Strongest cushion, but support load still matters.

What breaks first if MDM revenue slips or costs creep up?

Stress test

The plan has almost no cushion: break-even lands near $684k of annual revenue on $563k of fixed cost and an 82.3% contribution margin, meaning most revenue is left after variable costs. A 10% revenue miss or small cost creep pushes it into loss.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$684,000	$0 gap	At plan, there is no cushion.
Revenue shortfall	Revenue runs 10% below plan.	$684,000	$56,000 gap	A 10% miss turns breakeven into a loss.
Fixed-cost pressure	Fixed overhead rises 10% to about $619k.	$752,000	$68,000 gap	Overhead growth raises the bar fast.
Margin pressure	Variable costs rise 5 points; margin falls to 77.3%.	$728,000	$44,000 gap	Discounting or support load tightens the runway.
Combined pressure	Revenue is 10% lower, fixed costs rise 10%, and margin falls to 77.3%.	$802,000	$144,000 gap	Watch discounting, trial conversion below 22%, CAC above $85, and support hiring before device volume catches up.

Can this mobile device management service prove demand, margin, and support capacity before you scale hiring and paid marketing?

Founder checklist

Don’t add sales payroll or bigger ad spend until pilot trials convert at the modeled rate and the billing flow works for the $8, $18, and $45 plans. With Year 1 CAC at $85 and a modeled cash low of -$274K, the math has to work before the fixed-cost base grows.

1Pilot Demand22.0% trial-to-paid

Run pilot cohorts first and confirm trials turn into paid seats at the modeled 22.0% rate before you add sales payroll, because Year 1 CAC is $85 and weak conversion slows payback.

2Fixed Load$46.3K/mo

Delay office setup, hardware, and training until revenue is steady, because the fixed load is already about $46.3K a month.

3Unit Margin82.3% CM

Check that cloud, processing, and support tools stay near 17.7% of revenue, which leaves about 82.3% contribution margin to cover fixed cost and move toward break-even.

4Support Capacity4,650 devices

Test enrollment, policy setup, and ticket flow against the 4,650-device break-even volume, and write service-level commitments before support headcount rises.

5Cash Cushion-$274K low point

Set stop-loss triggers before cash hits the modeled low point of about -$274K in Month 37, because the plan does not pay back until Month 38.

6Spend Ramp$120K to $180K

Keep paid marketing at the Year 1 level until billing works for the $8, $18, and $45 plans, then review the step to $180K in Year 2 only after the funnel stays healthy.
