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 to watch for when vetting a planner. 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. 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 inexperienced - or building toward a high-pressure sales pitch.
Red flag 2: Hidden fees in the proposal
Read every proposal carefully for: "Staffing fees billed separately," "Technology fee," "Day-of coordination fee" (separate from the planning fee), "Service charge" (separate from gratuity), or "Markups on vendor invoices may apply." Each of those is a place where a $30,000 quote can quietly become $45,000.
Red flag 3: No relevant corporate references
Wedding planning experience does not equal corporate event planning experience. Ask for two references from corporate clients similar to your size and event type. If they can't produce them, or 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 first: What's the goal? Who's the audience? What's worked before?
Red flag 5: Long-term contract lock-in with no out-clause
A confident planner doesn't need to lock you in. They earn the renewal each year by doing the work well. Watch for non-refundable deposits regardless of cause and contract terms that aren't open to negotiation.
Red flag 6: They handle vendor payments through their account
The cleanest structure is: you pay vendors directly, the planner manages the relationship and the timeline. If a planner insists on routing all vendor invoices through their books, ask why - it's often where markups get buried.
Red flag 7: No process for what happens when things go wrong
Ask: "What happens if the keynote speaker cancels three days out?" A real planner will walk you through their contingency process, their backup vendor list, and the contractual protections they put in place. "Don't worry, we handle it" is not an answer.
Red flag 8: Communication is already slow
The pre-sale period is the most attentive a vendor will ever be. If it takes three days to return your initial inquiry, expect that pattern once you've signed.
Red flag 9: They badmouth other planners
Healthy competitive positioning sounds like: "Here's what we do differently." If they talk disparagingly 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, and vendor handling 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 request from any planner you're seriously considering
- A written proposal with all-in pricing
- Two references from corporate clients (not weddings)
- A sample contract you can review before deposit
- A walk-through of their contingency process
- Clarity on how vendor payments and reimbursables are handled
If a planner produces all five comfortably, you're probably in good hands. If you're navigating a vendor selection right now and want a second opinion, reach out. No pitch, no pressure.
