Which expenses are fixed and which move with sales in a network services business?

Cost classification

If you mix fixed overhead with usage-linked costs, break-even will look safer than it is. Classify each line first so Month 19 break-even depends on real gross margin, staffing capacity, and recurring overhead.

Expense Cost Break-Even Treatment Common Mistake
Office Rent and Facilities Fixed Include $6,000 monthly overhead from Month 1 through Month 60. Tying rent to job volume instead of treating it as base overhead.
Software Licensing and Monitoring Tools Fixed Include $3,500 monthly as required operating overhead. Burying monitoring tools in cost of goods sold and overstating margin.
Hardware and Equipment Costs Variable Apply 12% of first-year revenue in operating break-even math. Treating pass-through gear as pure profit.
Data Center and Colocation Hosting Fees Variable Apply 6% of first-year revenue for usage-linked hosting. Ignoring hosting fees that rise with client load.
Network Engineers Semi-fixed Add capacity in steps: 2 FTE in the first year at $120,000 each annually. Hiring ahead of contracted work and pushing break-even out.
Travel and Client Support Semi-variable Start with the $2,000 monthly support base and monitor site-visit growth. Missing truck-roll creep as the installed client base grows.
Insurance and Compliance Fixed Include $2,000 monthly as non-negotiable overhead. Classifying compliance as optional and understating the break-even floor.

How does break-even change as this network infrastructure business moves from lean to base to full coverage?

Scenario table

Break-even climbs from $93,394 a month in the lean setup to $240,909 in the full setup. Hardware and hosting get leaner as scale rises, but payroll and overhead rise faster, so the cash hurdle gets harder to clear.

Planning assumptions only; actual break-even will move with deal mix, staffing timing, and billing terms.
Scenario Monthly Revenue Variable Costs Fixed Costs CM Ratio Operating Profit Break-Even Signal
Lean network team $93,394 $16,811 $76,583 82% $0 Lowest hurdle; best for one core team.
Base growing field team $177,598 $26,640 $150,958 85% $0 Fits growth, but payroll keeps pressure on break-even.
Full multi-site coverage $240,909 $28,909 $212,000 88% $0 Strongest service reach, yet the highest cash hurdle.

What breaks this break-even plan for a network infrastructure business?

Stress test

The base plan only works with $93,394 of monthly revenue and no real cushion. A 10% sales miss, a 10% fixed-cost bump, or margin slip to 23% each pushes the business below break-even; together they can drive a deep monthly loss.

Stress Case Changed Assumption Break-Even Revenue Revenue Gap Risk Signal
Current plan No change. $93,394 $0 cushion There is no buffer if installs slip.
Revenue shortfall Monthly revenue falls 10% from plan. $93,394 $9,339 gap A 10% sales miss creates about a $7,658 monthly loss.
Fixed-cost increase Fixed overhead rises 10% to $84,241. $102,734 $9,340 gap Overhead creep adds almost $9.3k of revenue needed each month.
Margin pressure Variable expenses rise from 18% to 23%. $99,458 $6,064 gap At the same revenue, that means about a $4,670 monthly loss.
Combined pressure Revenue falls 10%, fixed costs rise 10%, and variable expenses rise to 23%. $109,404 $25,349 gap All three pressures together create about a $19,355 monthly loss.

What has to be true before you sign the lease and buy the network gear?

Founder checklist

Don’t lock in the space, staff, or core infrastructure until the monthly revenue path and cash runway both clear break-even. The model needs about $93.4K in monthly revenue, and it still shows a $376K cash gap at Month 19.

1Revenue path$93.4K/mo

Verify signed recurring support and add-ons can reach this monthly run rate before you commit to long leases or permanent hires.

2Overhead load$76.6K/mo

Check that base payroll, rent, tools, travel, and compliance costs can be covered every month without waiting on new bookings.

3Margin stack82% CM

Keep hardware pass-through visible, because 12% equipment cost and 6% hosting leave 82% contribution before overhead.

4Engineer ramp2.0→3.0 FTE

Add network engineers only after booked support can use the capacity, since staffing steps up fast in the second operating year.

5Cash gap-$376K

Plan for the Month 19 low point and fund the runway before you spend more on infrastructure.

6Launch CAC$1.5K

Keep Year 1 acquisition cost at $1,500, confirm vendor terms for servers, routers, and cabling, and separate the $730,000 setup capex from operating break-even.
