The planning break-even revenue is about $435k per month before adding discretionary acquisition budget: $36,983 / 85% = $43,510 If you treat the $150,000 Year 1 marketing budget as a fixed monthly commitment, the target rises to about $582k per month: ($36,983 + $12,500) / 85% Year 1 variable expenses equal 15% of revenue from hosting, integrations, digital advertising, and support scaling, so each $100 of revenue contributes about $085 to overhead The supplied model reaches break-even in Month 6 and shows Year 1 EBITDA of $91k

Break-even gets unreliable when fixed payroll, committed marketing, and usage-linked fees are blended. Here, $36,983/month of base overhead sits in the numerator, while Year 1 usage and acquisition lines reduce contribution margin.

Use $32,083/month for the Year 1 base team before later hiring steps.
Letting headcount rise automatically with every new subscriber.
Nonpayroll overhead
Fixed
Add $4,900/month for rent, retainers, licenses, insurance, utilities, internet, and supplies.
Leaving small recurring overhead out of break-even math.
Cloud Hosting & Infrastructure
Variable
Subtract 5.0% of Year 1 revenue from contribution margin.
Modeling usage infrastructure as one flat monthly bill.
Third-Party Integration Fees
Variable
Subtract 3.0% of Year 1 revenue as sales volume grows.
Burying integration fees in overhead instead of margin.
Digital Advertising & Content
Variable
Treat the 5.0% Year 1 line as revenue-linked acquisition spend.
Counting it again inside the CAC-funded marketing budget.
Customer Support Scaling
Variable
Apply 2.0% of Year 1 revenue to reflect support load from active customers.
Keeping support flat while transaction volume rises.
Committed marketing budget
Semi-fixed
If committed, spread the $150,000 Year 1 budget as $12,500/month.
Double counting CAC budget and the 5.0% advertising line.
QA Engineer and Sales Executive hires
Semi-fixed
Add hiring step-ups when the QA Engineer starts in Month 13 and Sales Executive starts in Month 25.
Smoothing later hires across all months from launch.
How does break-even shift as this cloud-based accounting software moves from lean to full scale?
Scenario table
Fixed payroll grows faster than the margin, so break-even revenue climbs with scale. The supplied model still hits break-even in Month 6, but the lean case has the tightest cushion and the full case has the widest.
Planning assumptions only; actual results will move with pricing, conversion, churn, and hiring pace.

What breaks the break-even plan for this accounting software?
Stress test
The base case clears break-even at about $43,510 a month, but it leaves little room for miss. A softer trial-to-paid rate, higher support load, or the $12,500 monthly marketing commitment can push the target up fast.

What should you verify before you lock in payroll and ad spend for this cloud accounting platform?
Founder checklist
Do not lock in recurring payroll or a bigger ad budget until the Month 6 break-even path holds. The model needs about $36,983 a month of fixed costs, $43,510 of monthly revenue to break even, and $824,000 of cash at the early low point in Month 2.
1Fixed Load$36.98K/mo
Confirm payroll and overhead are funded from launch, because the recurring cost base starts at $36,983 a month before sales catch up.
2Margin Stack85% CM
Keep hosting, integration, ad, and support spend near the model so each revenue dollar leaves about 85 cents for fixed costs.
3Demand Proof3.0% / 18.0%
Test whether visitors can reach free trial at 3.0% and trial users can convert to paid at 18.0%, or ad spend will miss payback.
4Pricing Mix$9.615K ARPAC
Check Solo, Team, and Enterprise pricing against $9,615 average monthly revenue per active customer so the mix supports the burn.
5Cash Cushion$824K
Keep the Month 2 cash trough funded, because the model’s low point hits before break-even and before the payback clock turns.
6Hiring RampMonth 13+
Delay noncritical hires if Month 6 break-even slips, since QA starts in Month 13 and Sales in Month 25 and both add fixed cost fast.
