Hidden Trade Show Costs Most Teams Forget

Beyond the obvious expenses—booth, space, travel—lie dozens of smaller costs that add up. These hidden costs aren’t actually hidden; they’re just easy to overlook during planning. Here’s what to look for.

Show Services Surprises

Electrical Beyond the Basics

You budgeted for electrical service, but did you include the cost of the actual connection? Many shows charge separately for the outlet installation in addition to the power service. Running electrical to an island booth location often costs more than perimeter spaces. For a complete breakdown, see our guide to trade show electrical and A/V costs.

Internet at Show Rates

Convention center internet is notoriously expensive. A basic wifi connection can run $500-$1,500. Hardwired connections for demos or heavy usage cost more. If you need reliable bandwidth for live demonstrations, budget accordingly.

Cleaning and Maintenance

Multi-day shows mean daily vacuuming, trash removal, and keeping your space presentable. Some shows include basic cleaning; others charge extra. Either way, someone needs to be responsible for booth appearance throughout the event.

Floral and Plants

That greenery that softens your booth? It’s rented, and it’s not cheap. A few plants can easily run $200-$500 for the show duration.

Logistics Hidden Costs

Empty Container Storage

Your booth arrives in crates and cases. Where do those go during the show? Empty container storage is charged by the piece or by square footage. For a larger booth, this can be several hundred dollars.

Forklift and Rigging

Heavy items or hanging elements require special equipment. Forklift service is typically billed hourly with minimums. Rigging for hanging signs or structures requires certified riggers at premium rates.

Overtime and Rush Charges

Anything that happens outside normal working hours—early morning setup, late-night fixes, weekend deliveries—incurs overtime rates. Emergency shipments can cost 3-5x standard rates. Understanding trade show labor costs in advance helps you plan around these premiums.

Staff-Related Costs

Meals and Per Diem

Hotel breakfast doesn’t cover lunch and dinner. Convention center food is expensive. Per diem for a team of four over five days adds up quickly—easily $1,500-$2,500 depending on the city.

Ground Transportation

Uber, Lyft, taxis, parking—the back-and-forth between hotel, convention center, airports, and client dinners accumulates. Budget $50-$100 per person per day for ground transportation in most cities.

Client Entertainment

Taking key prospects to dinner, hosting a happy hour, buying drinks at the networking reception—relationship building has real costs. These often come as surprises on expense reports.

Booth Staff Support

If you’re hiring temporary staff to help in the booth—brand ambassadors, demo specialists, interpreters—their fees plus any training time should be budgeted.

Marketing & Collateral Costs

Last-Minute Printing

You always need more than you print. Running out of brochures mid-show means rush printing at show-city prices. Build in a buffer or accept the premium.

Promotional Items

Giveaways, swag, branded items—these seem small individually but add up. A $5 item given to 500 people is $2,500. Plus shipping to the show.

Pre-Show Marketing

Email campaigns, social media promotion, direct mail to target accounts, show guide advertising—driving traffic to your booth costs money. This often lives in a different budget but should be considered part of show investment.

Technology Costs

Lead Retrieval

Show-provided lead scanners cost $200-$500 per device. Apps and third-party solutions have their own fees. You might need multiple devices for a busy booth.

Demo Equipment

Laptops, tablets, monitors for demonstrations—if they’re dedicated show equipment, their purchase or rental should be allocated. Don’t forget stands, mounts, and security cables.

Charging Stations

Providing phone charging for visitors is a traffic-builder, but the stations and power requirements add cost.

Post-Show Costs

Lead Follow-Up

Email campaigns, direct mail, sales follow-up time—converting leads into opportunities requires investment after the show ends.

Booth Refurbishment

Graphics get scuffed, components wear out, elements need refreshing. Post-show repair and update costs should be allocated per show.

Analysis and Reporting

The time spent analyzing results, preparing reports, and conducting post-mortems has value, even if it’s not a direct expense.
