Every lead retrieval vendor says it integrates with your CRM. The claim sits on every pricing page, usually above a row of logos. What it covers varies wildly: sometimes a live API that writes a deduped, attributed record in seconds, sometimes a CSV attachment that arrives two days after the show. Same phrase, different products.
This post is the cross-tool comparison: who connects to what, and what the connection actually is. The setup mechanics, field mapping, Lead vs Contact vs Campaign Member, dedup configuration, live in the companion how-to at event leads to CRM. Here we sort the tools.
Which event lead capture tools integrate with CRM systems?
Nearly every tool claims CRM integration. The real differences are native API vs CSV export, sync timing, and who charges for the access.
The logo wall proves almost nothing. Tendro, Captello, Momencio, and BoothIQ all list Salesforce and HubSpot integrations on their sites. iCapture, now folded into Cvent, connects inside the Cvent ecosystem. Organizer rental scanners technically "integrate" too, in the sense that a CSV can be imported into anything.
Three questions cut through the claims. Is the integration a native API connection or an export you process yourself? Does the lead arrive during the show or after it? And does anyone charge separately for the access, which organizer rentals routinely do. The rest of this post runs the major tools through those three questions. For the wider capture comparison beyond CRM, see best event lead capture apps, and the category pillar at event lead capture.
Vendor by vendor and CRM by CRM, the objects, fields, dedupe keys and attribution each app documents are laid out in the event lead capture CRM sync comparison.
What does "CRM integration" actually mean in lead retrieval?
Three tiers: a live native API that writes records directly, a CSV export you import yourself, or a third-party hop like Zapier in between.
Tier one is the native API integration. The capture tool authenticates against your CRM and writes the record directly: create or update the contact, map the fields, attach the event campaign. This is the only tier where "sync" means what a buyer assumes it means.
Tier two is the CSV export. The tool holds your leads, you download a file, you import it. Every organizer rental scanner works this way. The badge encodes an opaque registration ID, a license plate only the organizer's system can resolve, so the leads live in the organizer's portal until you export them. Rentals already run $400 to $700 per device per event, and organizers often charge again for API or CRM-integration access on top of the scanner fee. Read the order form before assuming the integration is included.
Tier three is the middleware hop. The tool connects to Zapier or similar, and Zapier connects to your CRM. It works, but you now own a second integration, a second bill, and a second place for field mapping to silently break.
Vendors describe all three tiers with the same phrase. When a pricing page says "integrates with Salesforce," your first job is finding out which tier you are buying.
How fast should event leads reach the CRM?
Fast enough that sequences and routing fire while the prospect still remembers the booth. Everything downstream keys off the CRM record.
The CRM is the system of record, so it is also the trigger layer. Rep notifications, assignment rules, follow-up sequences, and meeting links all fire when the record lands. A lead sitting in a vendor portal or a pending CSV triggers nothing. Sync timing decides whether follow-up starts on the show floor or the following Thursday.
The evidence on response timing and what it does to qualification rates is its own post: speed to lead at trade shows.
Which tools sync to Salesforce?
Most vendors list Salesforce. Depth is the variable: live API upsert with dedup at one end, a post-show CSV you upload at the other.
Tendro runs a native Salesforce integration: live API upsert with dedup and event attribution, so a scan becomes a deduped, campaign-attached record while the show is still running. Disclosure, I build Tendro, so filter accordingly. Setup detail is on the Salesforce lead retrieval page.
Cvent LeadCapture and iCapture sit inside the Cvent ecosystem. iCapture was folded into Cvent, and Cvent LeadCapture reportedly works only at Cvent-managed events. If your whole calendar runs through Cvent, that path covers you. If it does not, the integration does not travel with you.
Captello, Momencio, and BoothIQ all list Salesforce integrations. What I cannot tell you from the outside is the depth: which fields map, whether dedup runs, whether the sync is live or batched, and which pricing tier switches it on. Those details vary by tier and change without notice, so treat the vendor claim as a claim and run it through the checklist further down.
Organizer rentals are the floor of the range. Salesforce "integration" means a CSV after the show, exported from the organizer's portal, with API access often a separate line item on the order form.
Which tools sync to HubSpot?
Same story as Salesforce: widely listed, unevenly built. Ask whether the tool writes contacts live or hands you a file to import.
Tendro's HubSpot integration is native: contacts created or updated through the API, deduped, tagged with the event, in under 10 seconds. Details on the HubSpot lead retrieval page, and the workflow-level walkthrough in connecting trade show leads to HubSpot.
The rest of the field mirrors the Salesforce section. Captello, Momencio, and BoothIQ list HubSpot among their integrations. The depth question, live write vs batch vs middleware, is the one their pricing pages do not answer, and the answer can differ between a vendor's Salesforce connector and its HubSpot one. Cvent-ecosystem tools cover HubSpot within Cvent-managed events. Organizer rentals hand you the same post-show CSV regardless of which CRM you run.
What about Pardot, Marketo, Pipedrive, Zoho, and the rest?
Coverage thins out fast beyond Salesforce and HubSpot. Verify your specific CRM before buying; vendor integration lists rot.
Tendro's native connectors are Salesforce and HubSpot. Pardot, Marketo, Pipedrive, Zoho and the rest are built on request from the same sync layer, typically live within a day, and a webhook endpoint covers internal tools and the long tail. If your CRM exposes an API, the lead can land in it. The Marketo specifics, program membership and the status that carries attribution, are in the Marketo event lead capture guide.
For every other vendor the advice is the same: check your specific CRM against their current list before you sign, and confirm which tier of integration it is. Integration lists rot. Tools get acquired, iCapture into Cvent being the live example. Connectors get deprecated. A CRM that appeared on a marketing site in 2024 may now route through middleware. A logo on an integrations page is a snapshot, and often an old one.
What breaks CRM sync at a live event?
Venue WiFi, missing offline queues, duplicate records across shows, and leads that land without event attribution.
Venue connectivity is the first killer. McCormick Place's own guidance caps complimentary WiFi at 768 Kbps, and a packed show floor makes even that optimistic. A capture app that needs a live connection to record a scan loses leads in the dead zones.
The fix is an offline queue: scans stored locally on the device with full metadata, then synced in order when the connection returns. A tool without one fails exactly when the booth is busiest, which is when the leads are worth the most.
Duplicates are the second failure. The same buyer scanned at three shows becomes three records unless dedup runs at sync time. Then a rep cold-emails a prospect who already had two conversations with your team.
Attribution is the quiet one. A lead that lands without the event campaign attached looks like it came from nowhere. Six months later, when someone asks what pipeline the show produced, the answer is a shrug, and the event budget defends itself with anecdotes.
What should you test before trusting a CRM integration?
Run one test lead end-to-end before the show: check field mapping, dedup on a repeat scan, event attribution, and time the sync.
Do this the week before the event, on your production CRM, with your actual field configuration:
- Create one test lead end-to-end. Scan a badge or card and watch the record appear in the CRM. Not a demo environment. Yours.
- Check the field mapping, custom fields included. Standard fields usually survive. The custom ones, lead score, booth notes, conversation tags, are where mappings silently drop data.
- Scan the same person twice. A working integration updates the record. A broken one creates a duplicate, and it will do that a few hundred times over three show days.
- Confirm attribution. The test lead should land attached to the event campaign, not floating sourceless in the database.
- Time the sync. Scan to visible CRM record, on your phone's clock. If it takes minutes at your desk on good WiFi, plan for worse on the floor.
Twenty minutes of testing converts a vendor claim into an observed behavior. Every problem this list catches costs far more to fix mid-show.
How does Tendro handle CRM sync?
Native API sync in under 10 seconds, with dedup, event attribution, and an offline queue. $499 per event with unlimited team members, or a season pass.
Same disclosure as above: this is Tendro's blog.
The integration is tier one throughout: native API connections, no middleware hop. A scan becomes a deduped, event-attributed CRM record in under 10 seconds. Offline scans queue on the device and sync in order on reconnect, so the venue WiFi problem degrades timing, never data. Dedup runs at sync, so a repeat buyer stays one record across shows.
Pricing is $499 per event with unlimited team members, with a season pass for teams running a full calendar. The free trial covers scanning and enrichment, so you can desk-test capture quality before spending anything. CRM sync starts with the first paid event, so run the pre-show checklist above against that first event, not the trial. Start with the trial at app.tendro.com.
