Which expenses are fixed and which move with sales in a cross-border tax advisory firm?

Cost classification

Break-even is only useful when fixed overhead stays separate from revenue-linked delivery expenses. If you mix payroll steps, referral fees, and one-time setup spend, Month 9 break-even can look cleaner than cash will feel.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent and Utilities	Fixed	Use $6,500 per month in operating overhead from Month 1 through Month 60.	Treating rent as a percentage of revenue.
Professional Liability Insurance	Fixed	Use $1,200 per month as required baseline overhead before any client work is sold.	Leaving insurance out until revenue starts.
IT Infrastructure and CRM	Fixed	Use $850 per month as recurring operating software and systems overhead.	Mixing this with one-time server setup capex.
Specialized Tax Research Subscriptions	Variable	Model as 8% of first-year revenue, falling to 5.5% by Year 5.	Booking it as flat overhead despite revenue scaling.
External Jurisdictional Counsel Fees	Variable	Model as 12% of first-year revenue, then lower percentages as delivery efficiency improves.	Ignoring local counsel when pricing cross-border work.
Referral Partnership Commissions	Variable	Apply 5% of revenue across all forecast years because it moves with sales volume.	Counting referred revenue but excluding commission drag.
Payroll	Semi-fixed	Model payroll in staffing steps as full-time equivalent headcount changes by year.	Spreading salaries evenly as a revenue percentage.
Annual Marketing Budget	Semi-fixed	Use $45,000 in the first year, then step up with the planned annual budget.	Putting all acquisition spend into monthly variable CAC.

How does break-even change from a lean launch team to a full-service tax advisory model?

Scenario table

Break-even gets easier as the model adds more retainers, higher billable hours, and more staff. The lean launch case is still tight, the base case turns profitable, and the full-service case has the strongest cushion.

Planning assumptions only; actual break-even will move with client mix, pricing, staffing, and delivery costs.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch team	$81.4K	$23.6K	$69.3K	71.0%	-$11.5K	Still below break-even, so new retainers must cover fixed payroll.
Base small-team scale	$166.1K	$44.0K	$91.4K	73.5%	$30.6K	Above break-even, with enough cushion to absorb slower project timing.
Full-service scale	$483.4K	$103.9K	$183.2K	78.5%	$196.3K	Wide break-even cushion, helped by more billable hours and lower delivery drag.

What breaks the break-even plan for this international tax advisory service?

Stress test

Year 1 is already about $63K a month below break-even, so the cushion is thin. If revenue slips, fixed load rises to $797K a month, or margin stays at 71.0%, the gap opens fast.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$877K	$63K gap	Base case is already slightly under break-even.
Revenue shortfall	Year 1 average monthly revenue slips 8% to about $749K.	$877K	$128K gap	A small sales miss turns into a six-figure gap.
Fixed-cost pressure	Year 2 fixed load rises to about $797K a month.	$1.084M	$270K gap	Added payroll and overhead move the goalpost up fast.
Margin pressure	Year 2 contribution margin holds at 71.0% instead of 73.5%.	$1.124M	$310K gap	More external counsel, travel, or unpriced compliance work cuts cushion.
Combined pressure	Year 2 fixed load rises to about $797K a month, margin stays at 71.0%, and revenue slips 8% below Year 1.	$1.124M	$375K gap	Soft demand and heavier overhead together leave very little room.

What has to be true before you commit to the lease and hiring plan for this international tax advisory firm?

Founder checklist

Before you lock in heavy overhead, prove the pipeline, pricing, and client load can carry the model to Month 9 breakeven. If CAC, billable hours, or mix miss plan, hold the commitment and keep burn light.

1Pipeline Proof$2.5K CAC

Confirm Year 1 client acquisition stays near $2,500 per customer so new work can cover the monthly burn fast enough.

2Launch Rates$350 / $450 / $300

Test that buyers will accept these hourly rates for retainer advisory, project consulting, and compliance packages before you scale spend.

3Team Load8.5 hrs

Verify each active client can average 8.5 billable hours per month so the Year 1 team can stay loaded without hiring too early.

4Margin Mix71% CM

Hold contribution margin near 71% after research, external counsel, referral commissions, and travel, because weaker mix pushes breakeven out.

5Monthly Burn$58.5K/mo

Check the full Year 1 fixed load, including rent, insurance, IT, education, marketing, admin, and payroll, before signing on for heavier overhead.

6Cash Cushion$641K

Fund at least $641,000 before Month 8, since minimum cash lands in Month 8 and breakeven does not arrive until Month 9.
