Why I Finally Started Asking 'What's NOT Included?' Before Booking Anything

Stop Shopping on Sticker Price Alone

I manage purchasing for our company's events and team-building activities—roughly $60,000 annually across 8 vendors. Party venues, bounce house rentals, pool table deliveries for the break room, even bowling alley reservations for quarterly outings. For years, my process was simple: find the lowest base price, book it, move on.

I was wrong.

The turning point came in late 2023. I booked a trampoline park—let's call it Venue A—for a department event. Their website showed a per-person rate that looked fantastic. About 30% lower than the other place I was considering. I booked it. The day of the event, I got hit with a "mandatory party host fee," a separate "cleanup charge," and a $75 fee for using a credit card instead of ACH. The final bill was $1,420—more than I would have paid at the park I dismissed as "too expensive."

The question everyone asks is 'what's your best price?' The question they should ask is 'what's included in that price?'

"I've learned to ask 'what's NOT included' before 'what's the price.' The vendor who lists all fees upfront—even if the total looks higher—usually costs less in the end."

Three Hidden Costs That Keep Showing Up

After that experience, I started tracking the dirty laundry. Across party venues, bounce house rentals, and equipment suppliers for our offices, I see three patterns repeat. Each one is a lesson learned the hard way.

1) The Mandatory Add-On

Most buyers focus on the per-person price and completely miss the mandatory extras. Think party host fees, facility usage surcharges, or "required insurance" that's just a line item markup. One bounce house rental company quoted me $299 for a weekend rental. The base price looked great. Then came the delivery fee ($85), the setup fee ($50), the "sanitation fee" ($40), and a refundable damage deposit that was never refunded even though we returned the inflatable spotless.

Total: $474 for something advertised at $299. That's a 58% markup.

2) The Credit Card Tax

Around 40% of the venues I work with now charge a 3-4% convenience fee for credit cards. Some call it a "processing fee." Some just don't mention it until checkout. When you're booking for 50 people at $35 a head, that 3% is $52.50—not nothing. I now always ask: "Is this the price if I pay by card, or is there a discount for ACH or check?" The ones who are upfront about it? I trust them more. The ones who dodge the question? Red flag.

3) The Cleanup/Exit Fee That Appears Out of Nowhere

This one kills me every time. At a bowling alley we used for a team night, we paid a per-lane fee and shoe rental. Great. Then an hour before the event ended, the manager handed us an invoice for a "group cleanup deposit." We hadn't even eaten at the venue. It was a $200 charge that wasn't mentioned on the booking form, the confirmation email, or the phone call. I argued it. They waived half. Still left a bad taste.

Here's the thing: if you list all fees upfront, even if the total looks higher, I can budget for it. I can tell my VP what the real cost is. When you hide fees, you make me look incompetent. That's worse than the money.

Why Transparency Wins (Even When It Costs More)

People think expensive vendors deliver better quality. Actually, vendors who deliver quality can charge more. The causation runs the other way. The same logic applies to pricing transparency: vendors who are upfront about total cost can charge more because they're not wasting your time with surprise fees.

In our 2024 vendor consolidation project, I evaluated 12 venues for our annual company picnic. One vendor had a base rate that was 15% higher than the cheapest option. But when I asked for a full breakdown, they sent a single page with everything itemized: rental, staff, cleaning, insurance, payment method—all listed. No asterisks. No "subject to change" language. I booked them. The total came to $8,400. With the cheapest vendor's hidden fees, it would have been closer to $9,100.

Dodged a bullet on that one.

The Counterargument: "But My Boss Wants the Lowest Price"

I hear this a lot from fellow admins. "My boss just wants the cheapest option." To which I say: your boss wants the cheapest total cost, not the cheapest base price. When I present a proposal, I show the bottom-line total, not the advertised rate. I also show a comparison column: "Vendor A: $1,200 all-in. Vendor B: $999 + $180 in mandatory fees = $1,179." The numbers speak for themselves.

If your boss is still pushing for the lower base price, ask them one question: "Would you rather approve a $1,200 invoice you understand, or a $999 invoice that becomes $1,200 after the fact?" That usually settles it.

Also, worth noting: many vendors now offer online booking with instant price calculators. Those are great—if they include all fees. I've seen calculators that show a "starting from" price, then add 40% in mandatory extras at checkout. That's not a calculator. That's a bait-and-switch.

So Here's My Rule Now

Before I book any venue or equipment rental—whether it's a trampoline park for a kid's birthday or tables for the office party—I have a checklist. Not a formal document, but a mental one:

• Get the all-in quote in writing. Not just the base rate. Ask for breakdown of every fee: facility, staff, cleanup, insurance, payment method, delivery, setup, gratuity (some add 18% automatically).
• Ask the awkward question. "What could possibly be added to this bill that I'm not seeing?" The answer will tell you everything.
• Compare total, not base. Create a column for "all-in" and sort by that. The cheapest base price is often the most expensive option.

In my experience, the vendors who resist giving an all-in quote are the ones with the most to hide. The ones who say "Here's the price, and here's exactly what you get" are the ones I trust. Every time.

As of January 2025, I've saved our department about $4,200 annually just by switching to this approach. That's real money. And my VP noticed.

So if you're an admin buyer like me, skip the base-price game. Ask the real question. Your budget—and your sanity—will thank you.
