Why Your Shop Is Busy But Not Profitable

Guide · 2026-10-17

Revenue is the loudest number in the room and the least useful one. A shop can grow 40% year over year and still lose money, because every extra order multiplies whatever is broken in the unit economics.

Leak 1: fixed fees on small orders

A $0.30 per-order fee is 6% of a $5 order and 0.3% of a $100 order. If your catalogue skews cheap, your effective fee rate is far above the headline percentage. Bundling is not a marketing tactic here, it is a margin repair.

Leak 2: fee on shipping

Most marketplaces charge their percentage on shipping as well as the item. Sellers who list "free shipping" and absorb the postage pay the fee twice: once on the postage and once on the price they raised to cover it.

Leak 3: the subscription spread

A $39 platform subscription is $1.30 per order at 30 orders and $0.04 at 1,000. Low-volume sellers often blame product margin when the real problem is that fixed costs have not been divided by enough volume.

Leak 4: returns and refunds

Returns cost you the refund, the original payment fee (usually not returned), the return shipping, and sometimes a restocking fee. A 5% return rate on a 30% margin product can wipe out a third of your profit. Model it, do not assume zero.

Leak 5: ad spend measured against revenue

ROAS compares revenue to ad spend. Profit compares margin to ad spend. A 4x ROAS at a 25% margin returns exactly your ad spend in gross profit, which means you broke even on a campaign that looked like a winner.

How to find your leak in ten minutes

Take your last 20 orders and compute, for each one: revenue, every fee, product cost, shipping cost, and ad cost. Sort by net profit. The bottom five will tell you which of the five leaks above is yours.

Most sellers have never done this. The ones who do usually find that one product line is subsidising the rest.
