The show ends when the hall closes. The cost of the show doesn't. Invoices arrive for weeks, leads go cold in days, and the question "was it worth it?" gets asked by someone who wasn't there and wants a number. This is how to handle all three.
Part 1: The invoice audit
On a U.S. show you get one invoice from the general service contractor and a separate invoice from every exclusive vendor you used — electrical, internet, AV, cleaning, catering, lead retrieval — plus your carrier's. The first audit step is knowing how many invoices to expect. Missing invoices are as common as wrong ones, and they arrive later, after the budget's been closed.
Then, line by line:
Every line maps to an order. Pull the order confirmations. A line with no confirmation is either an on-site order (check your dispute log) or an error.
Every line is at the tier you ordered in. If you ordered carpet at the advance price and the invoice shows standard, that's a dispute. Your confirmation is the evidence.
Every drayage line maps to a shipment and a weight. Billed weight should equal your certified weight rounded up to the next hundred, or the minimum. Check the rate category — base, special handling, uncrated — against how the freight actually arrived. Check for late or off-target surcharges you didn't incur. Multiple small shipments each carry a minimum; that's legitimate, and it's why consolidation matters next time.
Every labor line maps to a signed ticket. Hours billed should match the hours on the tickets you signed. Supervision percentage should match what you ordered. A one-hour minimum for a cancelled call is legitimate only if you cancelled inside 24 hours.
Duplicates. The same item twice, on two invoices or on the same one. It happens.
Package items billed separately. If your rental package included carpet, structure labor or structure drayage, those shouldn't appear again — but your product's drayage and your own labor will, and legitimately so. Know what the package covered.
Cancelled items. Anything you cancelled before the free-cancellation cutoff should show a full credit. Refund timelines: card refunds commonly post within a couple of weeks after close, other payment methods four to six weeks. Put a reminder on it.
Dispute windows. Rental and service disputes were supposed to be raised before the show closed; drayage and labor disputes have windows too. Raise them in writing, with photos, immediately — the longer the gap, the weaker the position.
A good audit takes an hour per show and recovers something on most of them. The planner's vendor invoice tracker holds the expected invoices, the matched line items, and the dispute log you kept on site, so the audit is a reconciliation, not an archaeology project.
Part 2: Lead follow-up
Leads decay. The contact who was excited on Wednesday has forgotten your booth by the following Wednesday, and has had three other vendors follow up in between. The cadence that works:
- Day 1: the pre-written email, sent the morning after close. Thank you, one key message, one clear next step. Written before the show so it goes out without anyone writing anything.
- Day 3: segmented follow-up. Not everyone gets everything — the person who asked about pricing gets pricing, the person who asked about integration gets the integration page. Your on-site lead notes (twenty words per lead, rated A/B/C) are what make this possible.
- Day 7: A-leads get a call or a meeting request. B-leads get a second email with something useful.
- Day 14: anyone who engaged with anything gets a specific offer.
- Day 30: the last touch for the quiet ones, then they go into normal nurture.
Memorialize what you learned about each person — in the CRM, not in someone's notebook — so the salesperson who calls starts from knowledge, not from "I see you visited our booth."
Part 3: Measurement
Start with two numbers from before the show:
Breakeven leads. Total show cost divided by (average deal value × close rate). If the show costs $25,000, your average deal is $10,000 and you close one in five qualified leads, you need 12.5 qualified leads to break even. Set that target before the show. After the show, actual qualified leads against that target is the headline.
Budget versus benchmark. Industry surveys of exhibitor budgets put booth space around a quarter of total spend, show services (labor, drayage, electrical, cleaning, internet) a bit under a fifth and rising, exhibit design and construction mid-teens, shipping and travel around a tenth each, promotion high single digits, graphics mid single digits. If one of your categories is wildly outside those ranges, it's either a deliberate choice or a problem.
Then the post-show metrics:
- Cost per lead = total actual cost ÷ leads captured
- Cost per qualified lead = total actual cost ÷ A- and B-rated leads
- Cost per meeting = total actual cost ÷ meetings booked
- Pipeline created = sum of opportunity value opened from the show
- ROI = (revenue attributed − total cost) ÷ total cost, once deals close — which may be months later, so track it
- Savings captured = for every item ordered at advance pricing, the difference between the floor price and what you paid. This is the number that shows the planning itself paid for the planner.
Keep the measurement protocol identical across shows. Different goals per show are fine; different math per show makes the portfolio comparison meaningless.
Part 4: The one-page report
The person who approves next year's budget wants one page:
- Total cost by category, versus budget, versus benchmark.
- Leads, qualified leads, meetings, against the breakeven target.
- Cost per lead, cost per qualified lead, cost per meeting.
- Pipeline created and any closed revenue to date.
- Savings captured through advance ordering and disputes recovered.
- Three things that worked, three things to change.
- The rebook recommendation, with the booth size and location you'd want.
The planner generates this page from the data you entered during the show. Export it, attach it to the rebook request, and the conversation about next year's budget starts from evidence.
Part 5: Lessons learned and the next show
Survey the booth staff within a week — what slowed them down, what they wished they'd had, what attendees asked that nobody could answer. Survey a handful of visitors if you captured permission. Ask the organizer for attendee data and any booth-engagement metrics they collect; some now provide stop rates and dwell times.
Then decide the storage question if you haven't, decide the rebook, and clone the show in the planner with next year's dates. The deadlines, the vendor list, the budget and the lessons come with it. Next year starts already planned.
Frequently asked questions
- How do I audit a trade show invoice?
- Match every line to an order confirmation, every drayage charge to a certified weight rounded up to the next hundred pounds, and every labor hour to a signed ticket. Check that items are billed at the tier you ordered in, look for duplicates and package items billed twice, and confirm credits for cancelled items.
- How quickly should I follow up with trade show leads?
- The first touch the morning after the show closes, using an email written before the show. Then segmented follow-ups on days 3, 7, 14 and 30. Most leads go cold within a week.
- How do I calculate trade show ROI?
- Set a breakeven before the show: total cost divided by (average deal value × close rate) gives the qualified leads you need. After the show, track cost per lead, cost per qualified lead, cost per meeting, pipeline created and closed revenue over time.
- When should I expect refunds for cancelled trade show orders?
- Credit-card refunds commonly post within about two weeks after the show closes; other payment methods can take four to six weeks. Put a reminder on it.
