A logged-in customer taps Start CoCart on a restaurant page to become the host. CoCart generates an invitation link and a scannable QR code, and the host can pre-fill guest names so people can just pick their own from a list. Each guest lands on a join page, picks or enters their name, and orders from their own isolated cart - no account needed.
When a guest is done, they submit their selection to the host's group session. The host sees a full breakdown: subtotal per guest, tax share calculated proportionally, and tip share split equally - then pays for the whole table in one checkout, with each guest's name attached to their items on the final invoice.
