The problem
Too many moving parts become too many separate trackers.
Self-planning couples often manage money, guests, vendors and tasks in separate trackers, making it hard to see what is due or what changed downstream.
Wedding planning system
An all-in-one Excel wedding planner spreadsheet connecting budget, guests, seating, vendors, payments, tasks, decisions, milestones and the wedding-day schedule.

The problem
Self-planning couples often manage money, guests, vendors and tasks in separate trackers, making it hard to see what is due or what changed downstream.
The outcome
Keep the wedding plan connected so the next payment, RSVP state, seating attention, overdue task, decision deadline and milestone stay visible together.
