Most corporate event planners are good at what they do. A few aren't. The hard part is that the problems usually don't show up until the contract is signed and the deposit is in.

Here are the red flags I'd watch for when you're vetting an event planner, based on patterns I've seen across the industry. If you spot more than two of these in your first conversation, keep looking.

### Red flag 1: Vague pricing

A real planner can give you a meaningful price range within the first call. Something like: "For a 150-person holiday party in Orlando with full-service planning, you're looking at $15,000 to $25,000 in planning fees, depending on scope."

A planner who refuses to talk numbers, who keeps redirecting to "let's set up a deeper conversation," or whose first email is just a meeting request, is usually one of two things: inexperienced, or building toward a high-pressure sales pitch. Neither is what you want.

### Red flag 2: Hidden fees in the proposal

Read every proposal carefully for these phrases:

- "Staffing fees billed separately"

- "Technology fee"

- "Day-of coordination fee" (separate from the planning fee)

- "Service charge" (separate from gratuity)

- "Markups on vendor invoices may apply"

Each of those is a place where a $30,000 quote can quietly become $45,000. The best planners give you all-in pricing on the first page.

### Red flag 3: No relevant corporate references

Wedding planning experience does not equal corporate event planning experience. They're different disciplines with different stakeholders, different timelines, and different definitions of success.

Ask for two references from corporate clients similar to your size and event type. If they can't produce them, or if they offer wedding references instead, this isn't the right planner for a corporate program.

### Red flag 4: They oversell on the first call

If the first conversation is heavy on "we can do anything" and light on "here's what your event will actually look like," that's a pattern to notice. Confident planners ask diagnostic questions: What's the goal? Who's the audience? What's worked before? What hasn't? Then they propose a scope that fits.

Planners who promise the moon on call one usually deliver the same generic experience to every client.

### Red flag 5: Long-term contract lock-in with no out-clause

A common structure is the annual contract with 50 percent paid upfront. That's fine when there's a real reason for it. It's not fine when there isn't a 30-day termination clause, when the deposit is non-refundable regardless of cause, or when the contract terms aren't open to negotiation.

A confident planner doesn't need to lock you in. They earn the renewal each year by doing the work well.

### Red flag 6: They handle vendor payments through their account

Some planners require all vendor payments to flow through them, with markups added. Others insist on running vendor invoices through their books "for simplicity," which conveniently allows for percentage markups you may never see.

The cleanest structure is: you pay vendors directly, the planner manages the relationship and the timeline. Travel and accommodation reimbursed at actual cost with receipts, no markup. If a planner resists this structure, ask why.

### Red flag 7: No process for what happens when things go wrong

Ask: "What happens if the keynote speaker cancels three days out?" or "What happens if the venue double-books us?" A real planner will walk you through their contingency process, their backup vendor list, and the contractual protections they put in place.

A planner who hand-waves this question with "don't worry, we handle it," is a planner you should worry about.

### Red flag 8: Communication is already slow

If they take three days to return your initial inquiry, expect that pattern to continue once you've signed. The pre-sale period is the most attentive a vendor will ever be. If communication is already strained when they're trying to win you, it'll be worse when you're already locked in.

### Red flag 9: They badmouth other planners

Healthy competitive positioning sounds like: "Here's what we do that's different." Unhealthy positioning sounds like: "Don't work with [Competitor], they're terrible." If they talk that way about peers, they'll eventually talk that way about you.

### Red flag 10: The contract is short and vague

A serious planner has a real contract with scope, deliverables, payment terms, termination clauses, vendor handling, and IP ownership clearly defined. A two-page agreement that doesn't address what happens when things change is a sign that things changing wasn't planned for.

### What to do instead

When you're vetting planners, request:

1. A written proposal with all-in pricing

2. Two references from corporate clients (not weddings)

3. A sample contract you can review before deposit

4. A walk-through of their contingency process

5. Clarity on how vendor payments and reimbursables are handled

If a planner produces all five comfortably, you're probably in good hands.
