Booking the wrong vendor can derail your wedding day faster than bad weather. And the heartbreaking part? Most couples don't find out until it's too late to change course.
After coordinating over a hundred weddings, I've seen what happens when couples skip the right questions — and I've seen what happens when they ask them. The difference is night and day. This guide gives you the exact questions I recommend asking each vendor before you sign anything, plus the red flags that should send you running and the green flags that signal you've found someone you can trust.
Before any vendor meeting, pull up your wedding planning checklist so you know where you are in the process. Once you book, the vendor worksheets hub has a dedicated worksheet for each vendor type to track every detail through wedding day.
Photographer & Videographer
Your photos and video are the only things from your wedding day that last forever. Get this right.
- Will you personally be shooting our wedding, or will you send an associate?
- How many weddings do you shoot per weekend?
- What happens if you have a medical emergency on our wedding day — who is your backup?
- Can we see a complete gallery from a recent wedding, not just highlight shots?
- What is your typical turnaround time for delivering our images?
- Do you have experience shooting in low-light venues (candles, dim receptions)?
- What printing and sharing rights do we have to our images?
Red Flags
They can't show you a full wedding gallery — only curated highlight shots. They dodge the backup-photographer question. Their contract doesn't specify who will actually be there on your day.
Green Flags
They've shot your venue before (or a similar one). They walk you through their backup plan without hesitation. They ask questions about you — your relationship, what moments matter most, what you're nervous about.

Your Venue
Your venue sets every constraint for every other vendor. Lock this in first — everything else cascades from it.
- What is the maximum guest capacity, and does that number change with different room configurations?
- Are there noise ordinances or a hard end time for music?
- Is there a required vendor list, or can we bring in outside vendors?
- What is included in the rental — tables, chairs, linens, setup, teardown?
- How many other events will be happening the same day on the property?
- What are the load-in and load-out windows for our vendors?
- Is there a dedicated day-of venue coordinator, or do we need to hire our own?
Red Flags
They're vague about what's included in the rental fee. They can't confirm exclusivity of the space. Their "preferred vendor" list turns out to be a required vendor list — often with inflated pricing baked in.
Green Flags
They hand you a detailed event timeline and a clear breakdown of exactly what's included versus rented separately. There's a dedicated venue coordinator who is present for the entire event, not just setup.
Caterer
Food is the number one thing guests remember — and the number one complaint when it goes wrong. Don't treat catering as an afterthought.
- Can we schedule a tasting before signing the contract?
- How do you handle dietary restrictions and allergies, both during planning and on the day?
- What is the staff-to-guest ratio for service?
- How far in advance is the food prepared? When does it come off the line before service?
- What happens if a key menu item becomes unavailable closer to the date?
- Are gratuity and service charges included in the quote, or are they added separately later?
Red Flags
They won't offer a tasting. The initial quote grows by 20 to 30 percent once "fees" are added. They can't explain how allergy protocols are handled at the event level — not just on the planning call.
Green Flags
They've catered at your venue before. They proactively ask about allergies and have a documented protocol they can walk you through. The quote is itemized line by line with zero mystery charges.
DJ or Band
Music controls the energy of your entire reception. A skilled DJ reads the room and carries the party. A bad one can clear the dance floor in under an hour.
- Will you personally be DJing our event, or will you send someone from your roster?
- Can we provide a do-not-play list, and will you actually respect it?
- How do you handle song requests from guests during the reception?
- What is your setup time, and do you have backup equipment on-site?
- Have you worked at our venue before? Are you familiar with their sound system?
- How do you keep energy up during slower moments like dinner and toasts?
Red Flags
They can't confirm who will actually be at your wedding. They're dismissive about your do-not-play list or act like it's a burden. They haven't worked at your venue and don't ask for a walkthrough call with the venue coordinator.
Green Flags
They send a detailed questionnaire before the event covering your song preferences, key moments, and energy goals. They've worked your venue and know its quirks — loading dock, sound system, curfew times.
Track all confirmed details in the DJ & entertainment worksheet once you've signed.
Florist
Flowers are one of the most common budget surprises in wedding planning. Ask specific questions before you fall in love with a vision that doesn't match the quote.
- Can you realistically work within our budget, and if not, how would you recommend scaling back?
- Will the exact flowers I see in my inspiration photos be available during my wedding season?
- Does your quote include setup and breakdown, or just delivery?
- What happens if a specific bloom isn't available closer to the date — who decides the substitution?
- Can I see photos of completed weddings with a similar style to mine?
Red Flags
They promise specific flowers without checking seasonal availability. It's unclear whether setup labor is included. Their portfolio doesn't come close to matching your style and they don't ask about your venue's color palette or lighting.
Green Flags
They're upfront about substitutions and have a clear process for communicating changes before the order is placed. They ask about the light in your venue, the color palette of your linens, and how the florals will read in photos.
Document your final selections, colors, and delivery window in the florist worksheet.
Wedding Coordinator
If you're hiring a coordinator, this person will be your right hand on the most important day of your life. Vet them like it matters — because it does.
- How many weddings do you take per weekend?
- Will you personally be my coordinator on the day, or will you hand off to an assistant I haven't met?
- How do you handle vendor emergencies — a no-show, a late caterer, a bustle that breaks an hour before the reception?
- What does your day-of timeline process look like, and when do you start building it?
- How do you communicate with me in the final weeks leading up to the wedding?
- Can I speak with two or three recent couples you've worked with?
Red Flags
They're vague about who will actually show up on your wedding day. They downplay the importance of a detailed timeline. They can't provide references or get defensive when you ask for them.
Green Flags
They've coordinated at your venue. They ask about your biggest stress points and give specific, grounded answers. They walk you through a sample timeline from a past wedding without being asked — because they know that's how you understand what you're actually buying.
The Bottom Line
The best vendors welcome these questions. If someone gets defensive, rushes you, or gives vague non-answers — that's your answer.
Asking the right questions before you book is the single highest-leverage thing you can do for your wedding. It's not about being difficult. It's about walking into your wedding day knowing you built your team right.
