Record payouts, not just sales

Platforms deduct transaction, payment-processing and sometimes listing or ad fees. Record the gross, the fees and shipping from each payout report so totals match your bank.

Worked example

A $35 item with $5 shipping charged: at an example 6.5% transaction fee, 3% processing plus $0.25, and a $0.20 listing fee, fees come to about $4.25. With $9 of materials and $5.50 of postage, profit is about $21.25, a 53% margin. Rates here are examples; use your platform's current fee page.

Set aside as you go

Many sellers move a fixed percentage of each payout to a separate savings account. A tax professional can tell you what applies to you.
