Plan and track every line of the wedding spend in one screen. Pre-populated with standard categories (Venue, Catering, Photography, Flowers, Music, Attire, Stationery, Cake, Transport, Honeymoon, etc.). Each line: vendor name, estimated cost, actual cost once you have it, deposit paid so far, status (Planning / Booked / Paid in full). Live rollup at the top — projected total, remaining vs cap, deposits paid, balance still owed, and an "over by" callout if the projected total has crept past your cap.
