Long-press any sale to Edit Order — add or remove compounds, change quantities and prices, apply a discount, change the client or date. It edits the whole transaction, not just the line you pressed, and stock corrects itself automatically.
Duplicate Sale re-runs a past order for a returning client: same products and prices, dated today, unpaid, trimmed to what's actually in stock.
New sales start unpaid and show red until you mark them paid.
