@kevinkauffman Solid process. Add one step at the end: note what you paid for the card in the same place. At 200 sales that makes profit per card easy to pull.
A return costs more than the refund. Example data: return label 6.00, the original label you already paid 5.00, fees not refunded 1.50, new packing 0.90. That is 13.40 gone per return. Log it against the item so its real profit shows.
Etsy lists fees as a long run of separate lines. Grouping them by listing shows which products actually pay their way. In this example data the mug carries the most fees of the three. Check that view before you renew a listing that barely sells.
Packing supplies are a cost on every order even though no platform shows them. Example data: mailer, sleeve and toploader, tape and a thank you card come to 0.90 an order. Over 300 orders that is 270.00 your fee report never mentions.
Write three things down the day you buy stock: the date, what you paid including tax and shipping, and where it came from. A sale price is easy to look up later. Your buy cost usually is not, and your profit depends on it.
Profit per sale hides how long each sale took. Example data: vintage tops made 140.00 but needed 14 hours, so 10.00 an hour. Cards made 150.00 in 5 hours. Log hours next to profit for a month before you pick what to source more of.
@dudethatgolfs@CardPurchaser Congrats on going live. Write down what you paid for each card before the first one sells, it makes the profit math easy later.
