Party Planning RSVP & Vendor Coordination Checklist

Lock in your party date, time, and theme

Choose your date early—don't compete with other local parties. For seasonal parties (holiday, New Year), book 8+ weeks out. Document your theme and expected vibe so vendors understand the brief.

Scout and book your venue

Confirm capacity, parking, noise curfew, and any venue restrictions. Get written confirmation of your deposit date and cancellation policy. For block parties, confirm street permits and HOA sign-offs early.

Estimate your guest count range

Start with a realistic number based on your network. This drives all downstream decisions: catering quantities, bartender hours, furniture rentals, and music system size. Budget-per-head calculations start here.

Create your Who's In RSVP event

Set up at whos-in.app/create in 2 minutes. Add your party theme photo, description, capacity limit, and any dress code or theme requirements. Enable the 'Dietary Requirements' field for catering planning.

Research and shortlist vendors (catering, bar, DJ, florist, photographer)

Build your vendor shortlist for the services your party type needs. Get 2-3 quotes per vendor. Compare pricing on a per-head basis so you can lock your budget.

Confirm and book your caterer or food vendor

Sign contracts and pay deposits. Get their guaranteed final headcount deadline—this is usually 48-72 hours before. Note this in your party timeline. Ask about dietary accommodations and whether they'll track RSVPs with you.

Book your bartender, bar service, or beverage supplier

Confirm per-head cost, minimum spend, and whether they provide glassware and ice. Agree on final headcount deadline. For block parties, confirm alcohol licensing if needed.

Lock in entertainment (DJ, band, games, activities)

Book and brief them on your theme, guest count estimate, and must-play/no-play lists. Confirm arrival time, setup time needed, and technical requirements (power outlets, space).

Set your RSVP deadline (3 weeks out)

This deadline must align with your catering and bar final headcount deadlines—usually 48-72 hours before the party. Mark this clearly in your invites and on your RSVP page.

List what guests need to know or bring

Document dress code, theme requirements (costumes for Halloween/holiday parties), dietary preferences to declare, parking details, or any BYOB/bring-a-dish expectations.

Send your RSVP link everywhere (first push)

Post your Who's In RSVP link across all channels: group chat, email list, Facebook event, Instagram stories, local community boards, Nextdoor. For theme parties, make the theme visible in your messaging to get buy-in early.

Pin the RSVP link in your main group chat

Use WhatsApp, Telegram, or Messenger to pin your link where it stays visible. New invitees can find it without scrolling through 50 messages.

Check your current RSVP count and trend

Log into Who's In and review your numbers. If you're below 50% of your target, do a targeted second push to specific people. Note dietary requirements and any theme costume commitments.

Book secondary vendors (florist, photographer, games/rentals)

If needed for your party type, book and confirm delivery times. Confirm theme understanding (are flowers coordinating with your colour scheme? Does the photographer know the key moments to capture?).

Confirm vendor final headcount requirements

Email your catering and bar contacts. Check their final number deadline. Create a reminder in your calendar 72 hours before your RSVP deadline to confirm with vendors.

Send a personal chase-up to non-responders

Go through your invite list and message people individually who haven't RSVP'd yet. Use a friendly tone: 'Hey! Still coming to the [theme] party on [date]? I need an answer for catering.' Personal messages convert better than broadcast reminders.

Review dietary requirements and theme commitments

Go through your RSVPs on Who's In. Document vegetarian/vegan/allergy needs and pass to catering. Note who's committing to costumes for Halloween or themed parties—flag if you need to remind them.

Calculate your current budget-per-head

Take your total spend (venue, catering, bar, entertainment) and divide by your confirmed RSVPs. If it's exceeding your budget, decide now whether to reduce headcount or cut costs somewhere.

Arrange any theme-specific decorations or props

Order or DIY balloons, banners, lights, table settings. For holiday parties or themed events, do this now to avoid last-minute shortages.

Brief any volunteers or co-hosts

For larger parties, assign roles: entry greeter, bar assistant, food service, photo documentation, coat check. Send a message with the party timeline and their responsibilities.

Send a reminder to all RSVPs (automatic or manual)

Who's In sends automatic reminders. Include the date, time, location, parking details, dress code/theme requirements, and dietary form link. Mention any last-minute changes.

Check your RSVP count and flag non-commitments

Review who's said 'maybe' or left dietary requirements blank. Send a quick follow-up: 'Can you confirm yes/no so I can finalize catering?' You need locked numbers.

Finalize catering order with final headcount (or range)

Most caterers need 48-72 hours notice. Confirm your final number (or give a range like 'between 45-55'). Pass any dietary requirements and theme-specific requests. Confirm delivery/setup time.

Confirm bar final order and headcount

Same as catering. Confirm final guest count, drink preferences, and whether they're handling glassware/ice/cleanup. Confirm arrival and setup times.

Create your party run-of-show (timeline)

Document: arrival/greeting (15 min), appetizers (30 min), main course (45 min), entertainment/dancing (1.5 hrs), cake/toasts (30 min), wind-down. Share with DJ, caterer, and co-hosts so everyone is synchronized.

Confirm all vendor arrival and setup times

Email catering, bar, DJ, and florist with exact setup times. Confirm your contact number and venue access details. Reconfirm your party start time and guest count one final time.

Plan your table layout and seating if applicable

For dinner parties, farewell parties, or celebrations with speeches, sketch out your layout. Confirm how many high-top tables, dining tables, or lounge seating you need based on final headcount.

Gather any music playlists or entertainment requests

If you're curating music with your DJ, finalize your must-play list and any songs to avoid. For themed parties, share reference music that matches your vibe.

Prepare any speeches, toasts, or announcements

For farewell parties, retirement celebrations, or milestone events, write and time your remarks. Brief anyone else speaking. Confirm with your DJ when these are happening so they can lower music volume.

Test all tech and audiovisual needs

Microphone, speaker, projector, lights—test everything. For parties with slideshows or video tributes, have your file ready and backed up.

Send a final 48-hour reminder with logistics details

Who's In can send this automatically, or do it manually. Include: exact address with map link, parking instructions, dress code/theme reminder, arrival time, and any last-minute changes. This single reminder reduces no-shows by up to 40%.

Check for last-minute cancellations or changes

Review your RSVP list for any status changes. If you have a waitlist, reach out to backups immediately if spots open up.

Confirm final guest count with all vendors one last time

Call or email catering, bar, and entertainment. Give your final confirmed number. This is non-negotiable for accurate food/beverage quantities and budget lock.

Prepare your check-in process

Print a guest list with checkboxes, or set up Who's In's mobile check-in (scan QR codes on your phone). For larger parties (50+), designate someone as the check-in host to manage entry.

Finalize decorations and setup checklist

Confirm you have all decorations, setup supplies, and theme props. Create a checklist for setup day: table covers, centerpieces, string lights, signage, etc.

Arrive 90 minutes early for full setup

For larger parties (50+ guests), you need time to decorate, set up tables, brief vendors, and handle last-minute issues. This isn't optional—rushed setup always shows.

Coordinate vendor arrivals and setup

Be the point person when catering, bar, DJ, and florist arrive. Show them where to set up, confirm electrical needs, and run through the party timeline with them. Stay in touch via phone/radio.

Set up your entry experience

Clear signage, a greeter, and a 30-second check-in process make the first impression. Have your guest list ready. If you're doing themes, compliment anyone in costume loudly to encourage others.

Track actual attendance vs. RSVPs in real-time

Use Who's In to check guests in as they arrive. Note no-shows and walk-ins. This data helps you understand your RSVP-to-attendance ratio for future parties.

Capture photos and video throughout

Designate someone to take candid photos and a few videos of key moments (toasts, dancing, group shots). Take 20-30 photos minimum for social sharing and future promotion.

Monitor food, beverage, and vendor quality

Walk around during the party. Is food running out? Is the bar backed up? Is the DJ reading the room? Address issues before guests notice. Your job is to let everyone else do their job.

Manage the timeline (speeches, entertainment, transitions)

Use your run-of-show to keep the party flowing. Cue the DJ before speeches. Let catering know when to clear plates. A smooth timeline feels effortless—that's the goal.

Thank and pay your vendors (within 48 hours)

Send a message or call to catering, bar, DJ, florist, photographer. Pay any remaining balances promptly. Ask them if they'd recommend you to other planners—build your vendor relationship for next time.

Send thank-you messages to all attendees

Within 24 hours, thank everyone who came. Send from Who's In or manually. Include a highlight photo, a personal note about what made the party special, and a teaser for your next event.

Follow up with no-shows

Send a friendly 'we missed you' message within 48 hours. Ask if there was an issue and invite them to your next party. You recover 20-30% of no-shows with a genuine follow-up.

Post photos and videos on social media

Share your best 5-8 photos within 48 hours while people are still talking about the party. Tag your venue, vendors, and any special guests. Write a caption that makes non-attendees regret missing it.

Analyze your party metrics and budget

Review: invited vs. RSVPs vs. actual attendance, no-show rate, budget-per-head actual cost, vendor performance. Use Who's In's analytics to track this over time. What worked? What would you change?

Request vendor reviews or feedback

Email catering, DJ, photographer—ask them to share a testimonial or video clip of the party. This becomes social proof for marketing your next party.

Book your next party immediately

Strike while momentum is high. Create your next event on Who's In within 72 hours of this party ending. Excited attendees are your best marketing—announce the next date while the energy is fresh.
