Why teams connect Eloqua and Plex ERP

Feed the real customer, order, and revenue records from Plex ERP into Eloqua 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: Purchase orders, Customers, Suppliers, Shipments 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 Purchase orders, Customers, Suppliers, Shipments in Plex ERP with Contacts, Accounts, Custom Data Objects, Activities in Eloqua 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 Eloqua 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 Eloqua 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 Feed quality and scrap data to dashboards supervisors check without logging into Plex.
  • 02 Sync production and inventory data from Plex into a warehouse or Postgres for plant-level analytics.
  • 03 Export email opens, clicks, form submits, and bounces from the Bulk API Activities export into a warehouse for lead scoring and multi-touch attribution.
  • 04 Load purchase or product-usage records into Custom Data Objects linked to Contacts so nurture campaigns branch on behavior mastered in another system.

Common sync patterns

Where Eloqua captures new people: signups become customer records

Registrations, form fills, or new subscribers in Eloqua 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.

Purchase history drives segmentation

Orders, invoices, and revenue totals from Plex ERP land on the matching contact or account in Eloqua, so audiences are built from what customers actually bought and spent rather than from guesses.

What you can sync between Eloqua and Plex ERP

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Eloqua objects Plex ERP objects How this pairing syncs
Campaigns Multi-step campaign-canvas assets managed through the Application REST API; campaign membership and response data read out for attribution reporting. Shipments Outbound logistics records synced to trading partners and tracking systems Campaigns is specific to Eloqua and Shipments to Plex ERP — each maps to any object or custom field on the other side.
Emails Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync. Quality records Checksheet and inspection data pulled into plant dashboards Emails is specific to Eloqua and Quality records to Plex ERP — each maps to any object or custom field on the other side.
Forms and Form Submits Form definitions and their submission data, accessed through the Application REST API; submissions read out into a warehouse for lead capture and analysis. Parts Item master records shared with CRM, e-commerce, and planning tools Forms and Form Submits is specific to Eloqua and Parts to Plex ERP — each maps to any object or custom field on the other side.
Contact Lists and Segments Shared lists (static) and segments (dynamic audiences); Contacts are added to or removed from shared lists based on lifecycle stage computed downstream. Inventory On-hand balances and locations replicated for visibility outside the plant system Contact Lists and Segments is specific to Eloqua and Inventory to Plex ERP — each maps to any object or custom field on the other side.
Contacts Core person records, keyed on email address as the unique identifier; imported/exported via the Bulk API and upserted on email, synced two-way with CRM, warehouse, and app databases. Production jobs Shop-floor work records combining ERP and MES data for output reporting Contacts is specific to Eloqua and Production jobs to Plex ERP — each maps to any object or custom field on the other side.
Accounts Company records linked to Contacts via the account-linkage field; moved through the Bulk API and typically mastered in a CRM or ERP and written into Eloqua. Sales orders Demand records written in from e-commerce or EDI channels and read out for fulfillment status Accounts is specific to Eloqua and Sales orders to Plex ERP — each maps to any object or custom field on the other side.

How changes propagate between Eloqua 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.

Eloqua Plex ERP Interval-based propagation

DetectionStacksync polls Eloqua for changes on an incremental schedule, reading only records changed since the previous pass. Polling via Bulk API exports filtered on a contact/account modified-date field using EML filter syntax.

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

Rate-limit considerations

  • Eloqua: Per-instance soft limits by sync type (Export 2,000/hr, Import 2,000/hr, Sync Action 4,000/hr); 32 MB cap per POST to a staging area and 50,000 records per retrieve batch.
  • Plex ERP: Subject to the platform's API rate limits.
