Checklist, budget and moodboard
On the Wedding Day tab, under your run sheet: everyone working on the day, each with a call time and a private link to the day sheet. Send it on WhatsApp; they tap once to confirm, and you see who has.
Your run sheet is the plan for the day. Your wedding team, just below it, is who carries it out: the vendors you have booked, plus anyone who is not on the site, like the family's caterer or whoever is driving. Each of them gets a private link to a day sheet made from what you already have: the day, the venue with a map, their call time, the running order, who else is working, and the mood board you choose.
Change the run sheet or a call time and the page updates on its own; nothing needs re-sending. New link makes the old one stop working, for when a link went to the wrong chat.
Vendors see each other's names and roles, the times and what happens, and the mood board you choose. They never see each other's numbers, your notes on the run sheet, your budget or what you are paying anyone. Your planner sees and edits the team as they do the rest of your plan.
