Problem

Wedding planning wasn’t built for fragmentation.

Too many tools

Couples typically juggle five to ten apps — spreadsheets, email, RSVP forms, registries, and more — with no single source of truth.

Costs that creep

Per-guest and per-RSVP fees add up fast. Important features sit behind paywalls, and exports are an afterthought.

Logistics at scale

Hundreds of guests, dozens of vendors, multi-day weekends, dietary and accessibility needs — the complexity is real.

Solution

Purpose-built for the whole weekend — not a generic checklist app.

WeddingOS is a unified workspace for couples and planners: one guest graph, unlimited events, and modules that stay in sync from RSVP to day-of.

Master guest list

The guest record is the backbone: parties, plus-ones, dietary and accessibility tags, custom fields, import/export, and a foundation for every module.

Multi-event RSVPs

Model rehearsal dinners, welcome parties, ceremonies, receptions, and brunches as first-class events — per-event invites, deadlines, meals, and unified or split RSVP flows.

Seating & day-of

Interactive floor plans, drag-and-drop seats, table stats, print views, vendor sharing links, and a simplified full-screen mode when guests arrive.

Budget, vendors & comms

Estimates vs actuals, payment schedules, contracts, vendor logs, universal registry, couple’s website, and an automated email engine with merge tags and batch sends.

How it works

From first guest to last dance — without switching apps

    1. Create your wedding workspace

    Set the date, add partners and collaborators, and choose how you will host — self-managed or cloud. Invite a planner later if you use one.

    2. Build guests & events

    Import or enter your master guest list, create events for the whole weekend, assign who is invited where, and configure RSVP questions per event.

    3. Run RSVPs through day-of

    Send magic links and campaigns, track responses, finalize seating and vendors, then use check-in and day-of modes when it counts.

Features

Modules that share one guest graph and one source of truth

    Events

    Ceremony, reception, rehearsal, welcome party, brunch — each with its own guest slice, RSVP config, seating canvas, and comms.

    Guests & RSVPs

    Master list with parties, dietary and accessibility tags, magic links, QR batches, per-event responses, and offline admin entry.

    Budget & vendors

    Categories, estimate vs actual, payments linked to vendors, contracts, communication logs, and day-of vendor schedules.

    Timeline & tasks

    Engagement-to-honeymoon milestones, checklists, calendar sync, and minute-by-minute day-of runbooks.
