Which expenses are fixed and which move with sales for this custom products store?

Cost classification

Break-even is only useful if fixed charges stay below contribution margin, which is sales after variable costs. Here, product inputs, partner fees, shipping, and payment fees move with sales; platform tools and core subscriptions do not.

Expense	Cost	Break-Even Treatment	Common Mistake
E-commerce Platform Subscription	Fixed	Include $299 per month from Month 1 through Month 60 in fixed overhead.	Tying it to order count instead of monthly run-rate.
Website Hosting & Maintenance	Fixed	Include $150 per month from Month 1 through Month 60 below gross margin.	Burying hosting inside gross margin and hiding overhead.
Design Studio Software Licenses	Fixed	Include $100 per month from Month 1 through Month 60 as a fixed operating tool.	Treating it like per-order design labor.
Blank Product Cost	Variable	Apply 5.0% of sales in the first year and 4.8% in the second year.	Ignoring product mix when unit economics change.
Manufacturing Partner Fees	Variable	Apply 5.0% of sales in the first year and 4.8% in the second year.	Counting partner production work as fixed overhead.
Payment Processing Fees	Variable	Apply 2.5% of sales in the first year and 2.4% in the second year.	Using gross sales as profit before card fees.
Shipping & Packaging	Variable	Apply 5.0% of sales in the first year and 4.8% in the second year.	Assuming shipping is free to the business.
Customer Service Software	Semi-fixed	Add $80 per month starting Month 13 as support volume requires tools.	Adding support tools before support volume exists.

How does break-even shift from launch to scale for an online custom products store?

Scenario table

Break-even climbs as payroll and marketing expand, but a higher AOV and better mix keep the margin cushion strong. The lean launch case clears around $214k a month, while the full Year 3 case needs about $683k to cover the bigger cost base.

Planning assumptions only; actual break-even will move with mix, ad costs, and fulfillment.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch case	$214k	$37k	$176k	82.5%	$0	Launch is tight; small cost slips can turn profit negative.
Base Month 17 case	$443k	$74k	$369k	83.2%	$0	This is the planning case; break-even is near flat, so mix and CAC matter.
Full Year 3 scale case	$683k	$108k	$575k	84.2%	$0	Higher AOV helps, but added payroll and marketing keep the revenue bar high.

What breaks this custom store’s break-even plan?

Stress test

The plan is close to break-even, so small demand misses or higher fulfillment costs matter fast. A 15% revenue drop leaves a mid-five-figure gap, and a 5-point rise in variable costs lifts break-even revenue to about $472k.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$443k	$0 cushion	You have almost no room for error.
Revenue shortfall	Revenue falls 15% to about $377k.	$443k	$66k gap	A modest demand miss leaves a mid-five-figure hole.
Fixed-cost pressure	Fixed costs rise 10% to about $406k.	$488k	$45k gap	Overhead growth pushes the line higher fast.
Margin pressure	Variable expenses rise 5 points, cutting margin to 78.2%.	$472k	$29k gap	Higher CAC, shipping, or reprints can erase the cushion.
Combined pressure	Revenue falls 15%, fixed costs rise 10%, and variable expenses rise 5 points.	$519k	$142k gap	That stack of misses turns break-even into a steep loss.

What should you verify before you lock in ad spend, hiring, and inventory for this custom products store?

Founder checklist

Treat Month 17 break-even as the test, not the finish line. Don’t scale hard until pricing, margin, supplier speed, and support can all hold at the Year 2 plan.

1Pricing check$37.62 AOV

Verify the Year 2 mix and 1.15 units per order really land at this average order value before you spend more on traffic.

2Margin check16.8% costs

Keep blank product, partner fees, processing, and shipping near 16.8% of sales, because shipping drift or reprints can erase the cushion fast.

3Run-rate$16.1K/mo

Once the founder, marketing manager, and customer service rep are live, make sure sales can cover this fixed load before you add more spend.

4Throughput513 orders/mo

At break-even, check that proofing, reprints, refunds, and supplier turnaround can handle this order volume and keep blank inventory close to the $5K plan.

5Cash floor$806K min

Hold enough reserve to cover the Month 17 cash trough, since the model does not reach break-even until after a long ramp.

6CAC goal$32 CAC

Do not push the Year 2 marketing budget to $250K, or about $20.8K a month, until paid traffic moves from $35 CAC toward this level and conversion data is steady.
