What was the ROI of your last exhibition? Count the scanned cards.

The exhibition ROI formula, and why the numerator breaks

Exhibition ROI equals revenue traced to exhibition cards divided by total exhibition cost. The numerator depends entirely on whether the cards were scanned and source-tagged at the booth. Most B2B manufacturers approximate it with guesswork ("we got some good leads at the show"), which makes the sales and marketing ROI conversation political instead of mathematical. The b2b marketing ROI framework built on card scanning gives the numerator a hard number and turns the post-exhibition retrospective into a real ROI calculation you can defend.

The four inputs that make ROI honest

• Scan as numerator input — every card is a measurable contribution. Revenue attribution →
• Source-to-PO tracking closes the ROI loop. CRM workflow →
• Cost-per-scanned-card is your first efficiency metric. Hidden cost →
• Show-by-show comparison reveals which exhibitions actually deliver. Multi-channel tracking →

What honest exhibition ROI looks like in practice

When you can finally calculate exhibition ROI as a hard number, two things usually happen. One show turns out to deliver disproportionately better ROI than the rest, so marketing doubles down on it next year. Another turns out to be a waste, so marketing cuts it. Both decisions become possible only after honest measurement. VynDeal renders these reports automatically. See marketing's contribution to revenue for the upstream framework.
