Everything on the list, roughly in the order it needs doing
Not every wedding follows the same timeline, but most run into the same jobs. Use this as a starting point, not a rulebook.
Book the venue, set the guest list, secure the big vendors — photographer, caterer, band. These get booked up furthest in advance, so they go first regardless of what else is undecided.
Send invitations, finalise the menu, order the dress and suits, sort the details that make the day feel like yours — table cards, favours, a way for guests to actually share their photos with you afterward.
Final headcount, seating plan, rehearsal, and the small logistics: who's got the rings, who's collecting the cards at the end of the night, where the QR table cards are being printed and by when.
One line worth adding early: how guests will share their photos. Sorted in a few minutes, done well before the invitations go out. See the card designer.
