Which expenses stay fixed, and which move with orders for this buying platform?

Cost classification

Break-even is only useful if fixed overhead stays separate from per-order fees and acquisition spend. Mix them together, and Month 5 break-even can look safer than it really is.

Expense	Cost	Break-Even Treatment	Common Mistake
Office rent at $12,000 per month	Fixed	Include in monthly overhead before testing contribution margin.	Spreading rent across orders and hiding base burn.
Software SaaS subscriptions at $2,500 per month	Fixed	Treat as recurring platform overhead for the full planning period.	Dropping tools from break-even once revenue scales.
Payroll for engineering, product, seller success, and data roles	Semi-fixed	Add in steps as full-time headcount rises with operating scale.	Modeling salaries as if they flex with each order.
Payment gateway transaction fees at 3.5% in the first year	Variable	Deduct from revenue as order volume and payment value grow.	Using gross revenue instead of net contribution.
Cloud infrastructure and hosting at 4.0% in the first year	Variable	Model as usage-linked cost tied to platform activity.	Treating hosting as flat while traffic and orders rise.
Customer support outsourcing at 5.0% in the first year	Variable	Deduct with other volume-linked operating costs in contribution margin.	Assuming payroll alone covers all support demand.
Affiliate and referral payouts at 4.0% in the first year	Variable	Match payouts to sales or referred order activity.	Counting referred revenue without the related payout.
Buyer and seller acquisition marketing	Semi-variable	Model required spend using CAC: $15 per buyer and $300 per seller in the first year.	Treating CAC as free once the first campaign works.

How does break-even change from a lean launch to a base case and fuller rollout?

Scenario table

Break-even improves as revenue scales and variable costs stay near 15% to 17%. The lean case is close to the line, while the fuller rollout spreads fixed burn over more revenue and gives the biggest cushion.

Scenario figures are planning assumptions, not guarantees.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$229k	$38k	$138k	83.5%	$53k	Break-even sits near $165k per month, so this case has little room for a demand dip.
Base case	$829k	$130k	$243k	84.3%	$456k	Break-even sits near $288k per month, so this is the right point to prove density before scaling paid acquisition.
Full rollout	$2.27m	$341k	$405k	85.0%	$1.52m	Break-even sits near $477k per month, so the model has a much wider cushion.

What breaks the break-even plan for this group buying platform?

Stress test

Year 1 averages about $229k a month, so the plan has roughly a $68k cushion above the $161k break-even line. If revenue slips, or variable costs and fixed burn rise, that cushion can vanish before the Month 5 break-even holds.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$161,000	$68,000 cushion	The base plan clears break-even, but only with room to spare.
Revenue shortfall	Monthly revenue slips to $160,000.	$161,000	$1,000 gap	A small miss is enough to flip the month into operating loss.
Fixed-cost increase	Monthly fixed burn rises by $10,000.	$173,000	$56,000 cushion	Every extra $10k of burn lifts break-even by about $12k.
Margin pressure	Variable expenses rise by 10 percentage points of revenue.	$183,000	$46,000 cushion	That margin hit adds about $23k of monthly drag at the base run rate.
Combined pressure	Revenue slips to $160,000, fixed burn rises by $10,000, and variable expenses rise by 10 percentage points.	$196,000	$36,000 gap	Slower buyer conversion plus higher support load can wipe out the Month 5 break-even.

What should the founder verify before committing to a paid launch for a group buying deal platform?

Founder checklist

Don’t commit to paid launch until seller supply, buyer demand, checkout flow, support load, and CAC all clear the model. Break-even lands by Month 5, but you still need the $344K cash floor and you must keep build spend separate from operating break-even.

1Merchant supplyPre-launch

Secure enough seller commitments before platform spend so buyers see real deals and break-even does not rest on empty inventory.

2Buyer CAC$15

Test buyer acquisition near the $15 assumption before scaling the $500K first-year buyer budget, because higher CAC shortens runway fast.

3Seller CAC$300

Validate seller acquisition near $300 before spending the $150K first-year seller budget, since merchant cost has to stay inside the model.

4Checkout flowMonth 5

Prove checkout, payment gateway, refunds, and deal redemption work before launch, because payment breaks turn into lost orders and extra support.

5Support load50% revenue

Model support at 50% of revenue and staff to that load, or service issues can eat the margin needed for payback.

6Cash cushion$344K

Hold hiring until Month 5 break-even is real and Month 6 cash stays above the $344K minimum, while keeping one-time build costs out of operating break-even.
