A process validation service needs about $100K in monthly revenue to break even in Year 1 under these planning assumptions Here’s the quick math: fixed payroll, overhead, and marketing are about $71K/month, while subcontracted lab testing, calibration partner fees, travel, and commissions consume 29% of revenue, leaving a 71% contribution margin Break-even revenue is $71K / 71%, or roughly $100K/month The full model reaches break-even in Month 7, with Year 1 revenue of $1327M and EBITDA of $35K

Which process validation expenses are fixed, and which move with sales?
Cost classification
Break-even is only reliable when fixed overhead stays out of contribution margin and job-linked spend stays variable. In the first operating year, the main split is monthly overhead, revenue-based delivery spend, and capacity added through hires.

Common Mistake
Office Rent ($6,500/month)
Fixed
Include in monthly overhead for Month 1 through Month 60.
Allocating rent to each validation project.

Modeling it as usage spend per project.
Subcontracted Lab Testing (12% of first-year revenue)
Variable
Deduct from revenue before calculating contribution margin.
Putting lab work into fixed overhead.
Calibration Partner Fees (8% of first-year revenue)
Variable
Model as delivery spend that rises with project volume.
Treating partner fees as a flat monthly vendor bill.
Project Specific Travel (5% of first-year revenue)
Variable
Apply to project revenue because it follows client work.
Spreading travel evenly across all months.
Salaried Consulting Staff
Semi-fixed
Add in hiring steps as delivery capacity expands.
Assuming salary flexes with each billed hour.
How does break-even change from lean to full delivery in a process validation service?
Scenario table
As billable work scales, fixed overhead spreads out and break-even moves farther from the launch month. Higher realized rates, more billable capacity, lower partner fees, and tighter travel control all widen the cushion.
Planning assumptions only; actual break-even can move with realized hours, partner fees, and travel.

What breaks the Year 1 break-even plan for this process validation consulting business?
Stress test
Year 1 is tight. At about $100K/month break-even revenue, a 10% revenue dip, a 10% fixed-cost bump, or higher subcontract and travel costs can erase the cushion fast.

Underbilled hours, rework, travel overruns, subcontract support, and delayed client approvals can push the plan negative.
Is this process validation firm ready to commit fixed spend before it signs the lease and hires?
Founder checklist
Not yet, unless the pipeline and cash can carry the Month 7 break-even point. The model reaches break-even in Month 7, but it still needs $535K minimum cash and steady signed demand before it commits to the lease, capex, and senior hires.
1Signed Pipeline$100K/mo
Verify late-stage or signed work can cover at least $100K a month in Year 1, or about four $27K validation projects, before you lock the $315K capex and office lease.
2Fixed Burn$15.2K/mo
Check that fixed monthly costs stay near $15.2K, because rent, insurance, software, training, cloud tools, and admin hit cash even when field work slows.
3Contribution Margin71% CM
Use the Year 1 mix to confirm a 71% contribution margin, based on 20% subcontract and calibration cost plus 9% travel and commission; if mix shifts to lower-rate work, break-even moves out.
4Billable Capacity120 hrs
Make sure the team can bill 120 hours at $225 an hour without rework delay before you add another $135K senior engineer, or payroll will outrun delivery.
5Cash Runway$535K
Hold at least $535K through Month 7, because minimum cash lands in Month 7 and payback takes 23 months; that cushion keeps the buildout and payroll from choking the launch.
6CAC Gate$4.5K
Validate Year 1 customer acquisition cost near $4,500 before lifting marketing above $45K, since higher spend only helps if each new project still converts at a workable cost.
