Reporting closed won revenue from scans without overclaiming what the show did

A slide went round an exhibitions group last year with one line on it: the show delivered 1.4 million in customer revenue. It came from an exhibitor, it was accurate in the sense that the exhibitor had computed it from their own CRM, and nobody in the room could say what the word delivered meant. Reporting closed won revenue from scans turns on that one word.

Did those deals exist before the show? Were the buyers already in a cycle? Was the show the only marketing touch, or one of eleven? The slide did not say, the exhibitor's analyst had not been asked, and by the following quarter the figure had been repeated in a rebooking conversation, a sponsorship pitch and a board pack.

Revenue attached to a badge scan is the most quoted and least defined number in exhibitor reporting. Making it defensible takes a written rule and a published range.

Four verbs, and only two of them survive scrutiny

Attribution language is loose in a way that costs organisers credibility, so it is worth being pedantic about the verbs.

Sourced means the contact entered the exhibitor's database at the show. Checkable from the scan and the CRM creation date. A strong claim when it is true, and true for a minority of leads at most shows, because a large share of scanned badges belong to people the exhibitor already knew.

Touched means a contact on the opportunity was scanned at the show inside the agreed window. Checkable, cheap, and it makes no causal claim at all.

Influenced means the show contributed to the outcome. It is a modelling claim, and how much it is worth depends entirely on which model you ran and how many other touches existed.

Caused means the deal would not have happened otherwise. That requires a counterfactual, which requires a control group, which almost nobody has.

My position is that an organiser should report the second and stay out of the third and fourth. Show touched revenue, defined precisely, is a number you can hand to a finance director and defend line by line. Influenced revenue invites the reader to hear caused, and once that happens the number belongs to whoever quotes it last.

Write the rule before you compute the number

The rule needs four clauses and it fits in a paragraph on the report.

An opportunity is flagged show touched when a contact role on that opportunity matches a badge scanned by that exhibitor at that edition, and the opportunity was created after show open, and within the published attribution window, and the match came from a tier the exhibitor has accepted. Revenue on a show touched opportunity that later closes won is reported as show touched revenue.

Every clause is doing work. Created after show open excludes deals that were already running, which is the single largest source of overclaiming. The join that produces those matched contact roles is E14's. The window keeps the tail finite and is chosen against the exhibitor's own sales cycle, in E15. The accepted tier clause matters because a low precision match tier will drag wrong contacts into the flag, and the matching tiers are E16's subject.

CEIR's 2015 study on Exhibitor ROI and Performance Metric Practices found that exhibitors struggle with closing the loop on what becomes of their leads and with tracing exhibition leads back to sales conversion. A written rule does not close that loop by itself. It does mean that when the loop is closed, the number that comes out has a definition attached to it.

What does a single touch attribution model quietly do?

Most exhibitors will run this inside a CRM whose default attribution model is single touch, and the default is worth understanding before you accept a number produced by it.

Salesforce's documentation for Customizable Campaign Influence describes the Primary Campaign Source model as assigning 100 per cent influence to the campaign named in the Primary Campaign Source field on the opportunity. One campaign takes the whole deal. If somebody set the show as the primary campaign, the show gets all of it, including the portion any reasonable person would give to the six months of email nurture that followed.

This cuts both ways and that is the point. Where the show is the primary campaign, the number is inflated. Where a later webinar or an outbound sequence took the primary slot, the show gets nothing at all despite the buyer having been scanned on the stand. Two exhibitors with identical behaviour can report wildly different show revenue depending on which of their marketing team set a picklist.

An organiser who accepts a single touch number without asking which campaign held the primary slot is accepting a number generated by a field default.

Working it on 118 opportunities

Take an exhibitor with 118 opportunities flagged show touched under the rule above, measured at day 365.

By that point, 31 have closed won, 44 have closed lost, and 43 are still open. Win rate among resolved opportunities is 31 divided by 75, or 41.3 per cent. The exhibitor's baseline win rate across all opportunities in the same period is 34 per cent, so the show touched cohort runs about seven points ahead. That gap is interesting and it is association, since the same buyers who walk a show floor are the ones with active requirements.

Closed won value across the 31 deals: 1,364,000, averaging 44,000 per deal.

Now split the 31 by how many marketing touches their contact roles carry inside the window. Twelve of the 31 have the show as the only recorded campaign membership on any contact role. Nineteen have at least one other campaign.

Under a Primary Campaign Source model with the show set as primary, the reported figure is the full 1,364,000. Under a strict only-touch restriction, the figure is the 12 deals, worth 448,000. The same underlying data, the same window, the same matching, and a spread of more than three to one produced entirely by the attribution rule.

Report the range and name the rule

The version I would publish is one sentence with the range in it.

Show touched closed won revenue: 1,364,000 across 31 deals under a show-primary rule, of which 448,000 across 12 deals had the exhibition as the only recorded marketing touch. Window 180 days. Match tiers one and two. Baseline win rate 34 per cent.

That is longer than a headline figure and it is the only version that survives being quoted. Anyone who takes the 1,364,000 out of that sentence has visibly removed the qualification, which is a different situation from having never been given it.

The ratio between the two figures is itself worth tracking across editions. An exhibitor whose only-touch share is falling is running more marketing around the show, which is usually a sign of a maturing programme and not of the show mattering less. An exhibitor whose only-touch share is very high may have a CRM where nobody records anything else, which tells you the rest of their attribution is unreliable too.

Who is allowed to say the word revenue?

An organiser does not hold the revenue data and should not be the party asserting a revenue claim about an exhibitor's business.

What the organiser can do is define the rule, ship the key and the method, and publish the definition. The exhibitor runs it, the exhibitor owns the number, and the organiser reports it back as the exhibitor's own figure with the rule attached. That is a smaller claim and it is the only one the organiser can actually stand behind.

The CEIR Industry Insight Report on improving lead quality and sales conversion, written by Jefferson Davis of Competitive Edge and published by CEIR in 2019, defines a lead as anyone booth staff interacts with during the exhibition who requires follow-up, where that follow-up delivers measurable value for the exhibiting company. The measurable value clause sits inside the exhibitor's business, not the organiser's. An organiser who starts asserting revenue figures on the exhibitor's behalf has taken responsibility for a measurement they cannot audit, and the first time one of those figures is wrong in a rebooking conversation, it is the credibility of your whole exhibitor analytics that pays.

Where this stops

None of this establishes that the show caused any of the 1,364,000.

The scanned cohort self-selects. People who attend exhibitions and stop at a stand are disproportionately people with a live requirement and budget, which is precisely the population that closes deals whatever else happens. Comparing their win rate to a baseline that includes cold outbound contacts measures the difference between those populations at least as much as it measures the effect of the exhibition.

The only clean answer is a holdout, and the practical version is unglamorous: an exhibitor with enough volume can withhold show-sourced follow-up from a random slice of their scanned leads for a defined period and compare outcomes. Very few will agree to that, because it means deliberately not calling people they paid to meet. Absent a holdout, treat every figure in this post as a description of what happened to a group, and never as a statement about what the show produced.

There is also a timing trap. Deals closing after your window are invisible, deals closing inside it are counted in full, and an exhibitor who runs a long cycle will always look worse than one who does not, regardless of what your floor delivered them.

Write the four clause rule for your show, in one paragraph, and send it to the three exhibitors most likely to quote a revenue figure at you this year. Ask them whether the number they have been using would pass it. The answers will tell you how much of your own rebooking narrative is built on definitions nobody has read.
