A Won button (🏆) now sits in each conversation's bar on the web; in the app it is Won… in the conversation's menu. Write the amount, the currency and a note, and press Save the win. It counts for the Growth campaign that reached this person in the 14 days before — the WhatsApp offer sent to their number, or the post campaign that opened the conversation. Undo cancels a win: whoever saved it can within a day, an owner or admin at any time.
Amounts are kept in your workspace's currency, which an owner or admin confirms once — in Growth, or with their first win. Different currencies are shown side by side, never added up. Growth shows what came in over 30 days, what each campaign brought, and a What it brought tab.
