Reading your P&L
Which lines can I expand, and what is inside?
Seven of them. Discount codes breaks into the top codes plus a remainder and a row for automatic discounts; returns into the products that came back plus refunded shipping; net orders into new and returning; logistics into shipping, pick and pack, packaging, EPR fees and returns; transaction costs per gateway; marketing per platform; overhead into its largest costs.
Every breakdown adds up exactly to the line above it, to the cent. That is the property that makes expanding a row worth doing: the rows are the line, not an approximation of it.
Did this answer it? If not, a person who knows the product will.
