I've planned over 100 events in the last 4 years — corporate launches, networking dinners, conferences, private parties. Here's what I learned the hard way, distilled into the checklist I actually use now.

12 Weeks Out

• Lock the venue. Everything else is flexible. The venue is not. Book it before you have a final headcount — you can always adjust.

• Set your "non-negotiables." Pick 3 things that MUST go perfectly. For a product launch: AV quality, catering timing, photographer coverage. Everything else can be good enough.

• Create your master timeline. Not a to-do list. A reverse-engineered timeline that starts from the event date and works backwards. Every milestone gets an owner and a deadline.

6 Weeks Out

• Confirm all vendors IN WRITING. Verbal confirmations mean nothing. Get it in an email with the exact scope, timing, and pricing.

• Build your run-of-show document. Minute-by-minute breakdown of the event day. Who's where, doing what, at what time. This is the single most important document in event planning.

• Brief your team. Everyone working the event reads the run-of-show. No exceptions.

2 Weeks Out

• Do a venue walkthrough. Physically walk the space with your run-of-show in hand. Identify power outlets, dead zones, bottlenecks.

• *Prepare your "oh sht" kit.** Extension cords, gaffer tape, extra name badges, phone chargers, stain remover, printed vendor contact list. Trust me.

Day Of

• Arrive 2 hours before vendors. You set the tone. If you're calm, everyone's calm.

• Assign a "guest zero." One person whose only job is managing unexpected guest issues so you can focus on production.

• Take photos of the empty setup. You'll want these for your portfolio and post-event debrief.

After the Event

• Send a post-mortem survey within 24 hours. Ask 3 questions max: what was great, what could improve, would you come back.

• Debrief with your team within 48 hours while it's fresh. Document everything — wins, misses, vendor notes.

This is the skeleton. Inside EventFlow Pro, I share the full templates for each of these — the actual run-of-show docs, vendor brief templates, budget trackers, and timeline builders that I use on every event. Plus a community of planners who share their own post-mortems and vendor recs.
