Which digital room key platform expenses are fixed, variable, semi-variable, or semi-fixed at break-even?

Cost classification

Break-even is reliable only when fixed salaries and rent stay separate from revenue-linked fees. For this model, Year 1 break-even arrives in Month 1, so misclassifying commissions, hosting, or onboarding work can overstate margin fast.

Expense	Cost	Break-Even Treatment	Common Mistake
Payroll, $1.16 million in the first year	Semi-fixed	Treat salaries as monthly operating capacity, then step them up as planned hiring adds engineers, account executives, and customer success staff.	Spreading all payroll per hotel and hiding the step-up when active properties scale.
Office Rent, $7,500 monthly	Fixed	Include the full monthly rent in the fixed expense base for the relevant planning range.	Linking rent to customer count when the lease does not move with sales volume.
Industry Memberships & Trade Shows, $10,000 monthly	Fixed	Keep the monthly amount in fixed overhead unless the plan separately changes event spend.	Treating trade show spend as a sales commission and overstating contribution margin.
General & Administrative Software, $3,000 monthly	Fixed	Model it as recurring overhead that must be covered before operating profit.	Dropping back-office software below the break-even line because it is not tied to installs.
Cloud Infrastructure & Hosting Fees	Variable	Subtract 6.0% of first-year revenue, falling to 4.0% by the fifth year, before calculating contribution margin.	Using a flat server bill and missing usage growth as hotels, locks, and mobile keys increase.
Third-Party API & SMS Fees	Variable	Deduct 2.0% of first-year revenue, easing to 1.5% by the fourth year, as message and integration usage scales.	Ignoring API and SMS usage during onboarding and active guest access periods.
Payment Processing Fees	Variable	Apply 2.5% of revenue across the model because card fees rise directly with billed sales.	Modeling processing fees as fixed software spend instead of a revenue-linked drag.
Sales Commissions	Variable	Deduct 7.0% of first-year revenue, declining to 5.0% by the fifth year, before break-even contribution.	Treating one-time implementation revenue as stable monthly recurring revenue and overstating repeatable margin.

How does break-even change from a lean pilot to a full commercial rollout?

Scenario table

Break-even rises as the rollout gets bigger because fixed overhead and variable costs both climb with scale. The margin stays strong, but the business needs more recurring hotel revenue to cover the heavier monthly base.

Planning assumptions only; room count and hotel count are calculator inputs, so results can shift.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean pilot rollout	$486.3k	$85.1k	$142.3k	82.5%	$258.9k	Revenue sits well above break-even, so the pilot has room.
Base rollout	$982.3k	$148.3k	$205.6k	84.9%	$628.4k	The cushion is still strong, but conversion needs to stay steady.
Full commercial rollout	$1.434M	$186.4k	$273.1k	87.0%	$974.3k	Break-even stays reachable, but the larger cost base needs more scale.

What breaks the break-even plan if hotel adoption slows?

Stress test

Break-even is solid at the base plan, but it gets pressured fast if deployments slow, discounts deepen, or support work rises. Even so, the model stays above break-even in each stress case below.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$172,500	$313,800 cushion	Base plan clears break-even with a wide cushion.
Revenue shortfall	Monthly revenue drops 20% to about $389,000.	$172,500	$216,500 cushion	The business still clears break-even, but the buffer shrinks fast.
Fixed-cost pressure	Fixed overhead rises 15% to about $163,645 a month.	$198,358	$287,900 cushion	Overhead creep lifts the break-even bar, even before revenue changes.
Margin pressure	Variable expenses rise to 22.5% of revenue.	$183,613	$302,600 cushion	Support and implementation drag cut margin, but the plan still holds.
Combined pressure	Revenue falls 20%, variable expenses rise to 22.5%, and fixed overhead rises 15%.	$211,155	$177,800 cushion	Multiple pressure points cut the cushion sharply, but break-even still holds.

What should you verify before committing to the first hotel rollout?

Founder checklist

Test the funnel, pricing, integration, and support load before you scale. The model only holds if demo requests hit 15%, pilots convert at 60%, and the $869K cash floor is covered.

1Demo Demand15%

Verify visitors turn into demo or pilot requests at about 15%, or the Year 1 pipeline won't feed paid trials fast enough.

2Pilot Close60%

Verify pilots convert to paid contracts near 60%, because weak close rates push back revenue and make break-even look fake.

3Price Mix50/40/10

Verify Year 1 bookings land near 50% Basic Access, 40% Pro Operations, and 10% Enterprise Suite, with monthly prices at $3, $5, and $8 plus one-time fees of $2,500, $4,000, and $7,500.

4Integration FitPMS + locks

Verify property-management-system integration and lock vendor compatibility before scale, because failed installs slow go-live and raise support work.

5Margin Load82.5% CM

Verify variable costs stay near 17.5% of revenue and fixed burn stays near $121.5K/mo, or the break-even math will move fast.

6Runway Check$869K

Verify the $869K minimum cash cushion is funded, because Month 1 is the cash low point, and keep customer success at 1.0 FTE until onboarding is stable.
