Why teams connect Cvent and Plex ERP

Feed the real customer, order, and revenue records from Plex ERP into Cvent so campaigns run on who actually bought what, and let contact and consent changes flow back in real time.

Marketing runs on lists of people, but the list rarely knows which of those people are paying customers, what they ordered, or what they are worth. Plex ERP holds exactly that: Parts, Inventory, Production jobs, Sales orders that record who the customer is, what they bought, and what they owe. When the two are joined only by a periodic export, campaigns go out against stale audiences, existing customers get prospecting emails, high-value accounts look the same as cold leads, and a canceled order still counts toward a segment.

Stacksync syncs Parts, Inventory, Production jobs, Sales orders in Plex ERP with Budgets, Events, Contacts, Attendees and Registrations in Cvent in real time, and where both sides accept writes, in both directions. Customer, order, and invoice data maps field by field onto the contacts, audiences, or accounts Cvent works with, so segmentation and personalization run on current purchase history instead of a month-old snapshot. Contact details and consent changes that originate in Cvent flow back onto the record in Plex ERP.

The strongest bridge between the two is identity and purchase history, who the customer is and what they have bought, so that is where most of the value sits. Because the sync is field-level, each system keeps the attributes the other has no use for; only the shared records are held in agreement.

Common use cases

  • 01 Sync production and inventory data from Plex into a warehouse or Postgres for plant-level analytics.
  • 02 Keep customers, parts, and pricing aligned between Plex and the CRM the sales team uses.
  • 03 Write Attendees and Registrations into Cvent from external marketing signup flows, then read attendance status back into a warehouse.
  • 04 Sync Sessions and Speakers into a content database or agenda app so schedule and speaker changes propagate without manual re-entry.

Common sync patterns

Lifecycle triggers from back-office events

A first order, a renewal, or a lapsed account recorded in Plex ERP appears in Cvent within seconds, ready to start or stop a lifecycle campaign.

Where Cvent captures new people: signups become customer records

Registrations, form fills, or new subscribers in Cvent create or update the corresponding record in Plex ERP, so the back office sees them without anyone re-keying.

Consent and contact changes travel

Email, address, or subscription-status changes stay aligned across both systems, so a customer who updates their details or opts out is respected everywhere.

Attendees and Registrations Per-event registrants; written in from CRM or marketing signup flows via POST /ea/attendees and read back out to a warehouse for attendance and registration-status reporting. Inventory On-hand balances and locations replicated for visibility outside the plant system Attendees and Registrations is specific to Cvent and Inventory to Plex ERP — each maps to any object or custom field on the other side.
Sessions Agenda items within an event; listed or created through the API and synced so session-level attendance feeds reporting tables. Production jobs Shop-floor work records combining ERP and MES data for output reporting Sessions is specific to Cvent and Production jobs to Plex ERP — each maps to any object or custom field on the other side.

How changes propagate between Cvent and Plex ERP

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Cvent Plex ERP Sub-second propagation

DetectionCvent notifies Stacksync of record changes through webhook events. Per-event webhooks push attendee, registration, session, and speaker changes.

DeliveryEach detected change is written to Plex ERP through its API, with automatic retries and rate-limit backoff.

Plex ERP Cvent Interval-based propagation

DetectionStacksync polls Plex ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

DeliveryEach detected change is written to Cvent through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Cvent: Responses carry X-RateLimit-Limit/Remaining/Reset headers; a 429 signals either the per-second limit (retry with exponential backoff from ~2s) or the daily quota (up to 500,000 calls/day on the Premium tier, 1,000/day on Free) exhausted until midnight UTC.
  • Plex ERP: Subject to the platform's API rate limits.
