Wedding Planning OS — Budget Engine, Guest List & RSVP, Vendor CRM, Seating & Countdown Timeline

One calm Notion command center for the whole wedding that does the math. Set your date and the entire timeline dates itself; RSVPs auto-tally your headcount and meal counts; expenses roll up into a live budget with over-budget flags; and a vendor CRM tracks quotes, balances and payment due dates. Includes seating with live table fill, a thank-you tracker and 40+ AI wedding prompts.
