Recording and editing sales

A sale is an order: any number of item lines plus order-level shipping charged, label cost, and discount. Picking a channel prefills its shipping defaults; all stay editable — this order's real postage wins. Fees apply once per order, and discounts come off the item total before fees (as marketplaces do).

In Sales history, click an order to expand its full breakdown — line items on the left, the economics waterfall (gross → fees → net → cost → profit) on the right — with Edit and Delete right there. Most orders shouldn't be typed at all: use CSV import.
