Most events don't fall apart because of the big things — the wrong venue, the wrong caterer. They fall apart because of the 48-hour confirmation that didn't happen. The vendor who thought they had the right load-in time. The florist who wasn't told the floor plan changed.
The event vendor checklist is the document that closes those gaps. Here's the complete version, organized by category, with what to confirm at each milestone and how to run day-of vendor communication.

What to Confirm with Every Vendor 48 Hours Out
The 48-hour confirmation window is the most important vendor communication you make. Not the booking confirmation 8 weeks ago. Not the casual "we're all set" check-in 2 weeks out. The 48-hour call or email.
Universal 48-Hour Confirmation Items
- Date, venue address, and load-in entrance — even if you've confirmed it before. Vendors work multiple events. Confirm it again.
- Their specific arrival time — not "afternoon," the exact time.
- Their setup window duration — do they have enough time given when other vendors arrive?
- Who they check in with on arrival — you, the venue manager, or a coordinator on-site.
- Any last-minute changes — floor plan updates, headcount changes, vendor swaps.
- Their day-of contact method — are you texting? Radio? They need to know how to reach you.
Category-Specific 48-Hour Items
Catering: Confirm final headcount. Confirm dietary accommodation list is received. Confirm kitchen access time.
Florals: Confirm centerpiece count matches final table layout. Confirm delivery window and who receives them on site.
AV/Entertainment: Confirm tech setup window. Confirm who owns the AV-to-entertainment handoff.
Photography: Share the latest timeline. Flag any program changes since your last conversation.
Rentals: Confirm delivery window. Confirm someone with venue access will be present to receive.
Day-of Vendor Communication Guide
On Arrival
Every vendor should receive, at arrival:
- A copy of the production timeline (their section highlighted)
- The floor plan
- Your cell number and the venue manager's cell number
- Their specific assignment for the day
Do not brief vendors verbally and send them off. Hand them paper. Verbal briefings evaporate.
Communication Channels by Event Size
| Event Size | Communication Method |
|---|---|
| Under 75 guests | Cell phone — direct calls/texts |
| 75–200 guests | Two-way radios (coordinator + all department leads) + cell backup |
| 200+ guests | Dedicated event radio channel per department + command post |
When Things Change
When a timeline changes on event day — and it will — notify only the vendors who are affected by that specific change. A kitchen delay doesn't require a call to the AV team. A ceremony running long requires immediate notification to: bar team (delay cocktail hour), catering (hold appetizer deployment), photography (adjust portrait timing).
Notify with precision, not panic. "We're running 12 minutes behind. First course drops at 7:07 instead of 6:55. Please hold." That's the call. Make it once.
