Cost classification

The model reaches break-even in Month 31, so bad cost classification can move that date fast. Keep rent fixed, supplies and commissions variable, and wages, marketing, and fleet in the right step or usage buckets.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Use $8,500 per month as base overhead.	Spreading rent across routes and hiding true overhead.
Warehouse Rent	Fixed	Use $4,200 per month until space needs change.	Treating storage space as if it rises with each job.
Year 1 Wages	Semi-fixed	Use about $75.3k per month, then add staff in blocks.	Treating technicians as pure overhead when route volume drives staffing.
Marketing Budget	Semi-fixed	Use $15,000 per month in the first year campaign plan.	Modeling campaigns as a clean percent of each sale.
Cleaning Supplies and Chemicals	Variable	Subtract 12% of revenue before covering overhead.	Budgeting supplies as flat overhead instead of route-driven spend.
Restroom Consumables	Variable	Subtract 8% of revenue as usage rises with service volume.	Ignoring higher paper, soap, and refill use on busy routes.
Sales Commissions	Variable	Subtract 5% of revenue tied to closed customer volume.	Putting commissions in fixed payroll and overstating margin.
Vehicle Fleet Operations	Semi-variable	Model the 8% route-linked portion with a base fleet plan.	Treating fuel and route wear as pure overhead.

How does break-even change across lean, base, and full route coverage?

Scenario table

Break-even here is driven by route density, since variable costs take about 40% of revenue and 60% is left to cover fixed overhead. Lean volume still burns cash, the base case sits at break-even, and full coverage creates a small cushion.

These are planning cases, not guarantees; actual results will shift with route mix, labor, and contract timing.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean route coverage	$130.3K	$52.1K	$97.8K	60%	-$19.6K	Still below break-even, so cash burn continues.
Base route coverage	$162.9K	$65.2K	$97.8K	60%	$0	Sits at break-even, so any slip turns it negative.
Full route coverage	$203.6K	$81.5K	$97.8K	60%	$24.4K	Creates a modest cushion if routes stay dense.

What breaks first if contracts, labor, or overhead slip?

Stress test

This plan is most exposed to contract density and labor-heavy routes. A 10% revenue miss can burn about $113K a month, while a 10% fixed-cost jump or a 5-point margin drop pushes break-even to about $2.07M or $2.06M a month.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$1,883K/month	$0 cushion	Base plan sits at break-even.
Revenue shortfall	Revenue runs 10% below break-even.	$1,883K/month	$188K gap	That miss drives about $113K monthly loss.
Fixed-cost increase	Fixed overhead rises 10%.	$2,067K/month	$184K gap	Admin and overhead growth quickly eat cushion.
Margin pressure	Variable expense rises from 40% to 45%.	$2,055K/month	$172K gap	Longer routes and higher technician burden squeeze margin.
Combined pressure	Fixed costs rise 10% and margin falls to 55%.	$2,255K/month	$372K gap	Weak contract density makes breakeven much harder.

What should the founder verify before locking in routes, staff, and vehicles?

Founder checklist

Confirm you have signed or near-signed recurring work before you lock in the fleet and payroll. This model does not break even until Month 31, and the cash trough reaches about -$1.138M, so weak demand shows up fast.

1Demand Proof$450 CAC

Verify you can win recurring customers at about $450 CAC before you commit to route growth, because slow close rates make the launch spend hard to earn back.

2Fixed Load$97.8K/mo

Check that booked revenue can carry the Year 1 wage and overhead load of about $97.8K a month, or fixed costs will outrun the route base.

3Contribution60% CM

Hold the full variable stack near 40% of sales, which leaves about 60% contribution margin if supplies, fleet use, commissions, and software stay on plan.

4Package Mix$299/$599/$999/$149

Validate that buyers will accept the Year 1 mix across Basic, Premium, Elite, and add-ons at these prices, because the wrong mix cuts revenue per account.

5Tech Load8 FTE

Map workload to the Year 1 plan for 8 cleaning technician FTEs and 12 billable hours per active customer each month so labor stays tied to route demand.

6Capex Timing$285K

Delay the $180K fleet, $65K cleaning equipment, and $40K inventory buys until route usage is proven, or you will trap cash in assets too early.
