Why teams connect Eloqua and Sage 300

Feed the real customer, order, and revenue records from Sage 300 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. Sage 300 holds exactly that: AP Vendors, GL Accounts, Journal Batches, Order Entry 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 AP Vendors, GL Accounts, Journal Batches, Order Entry Orders in Sage 300 with Activities, Campaigns, Emails, Forms and Form Submits 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 Sage 300.

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 AR customers, invoices, and balances into a CRM for multi-currency account visibility.
  • 02 Write web and EDI orders into Order Entry and return order status to the source channel.
  • 03 Load purchase or product-usage records into Custom Data Objects linked to Contacts so nurture campaigns branch on behavior mastered in another system.
  • 04 Add or remove Contacts from shared Contact Lists and Segments based on lifecycle stage computed downstream in a database.

Common sync patterns

Suppress or target existing customers

Because Sage 300 knows who is already a paying customer, Eloqua can exclude them from acquisition campaigns or single them out for renewal and cross-sell.

One customer identity across both systems

A person or company's contact details corrected in either system update the other, so marketing and the back office stop maintaining separate versions of the same record.

Lifecycle triggers from back-office events

A first order, a renewal, or a lapsed account recorded in Sage 300 appears in Eloqua within seconds, ready to start or stop a lifecycle campaign.

What you can sync between Eloqua and Sage 300

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 Sage 300 objects How this pairing syncs
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. AR Customers Receivables customer master synced to CRMs and billing tools. Contacts is specific to Eloqua and AR Customers to Sage 300 — 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. AP Vendors Payables vendor master synced with procurement and payment systems. Accounts is specific to Eloqua and AP Vendors to Sage 300 — each maps to any object or custom field on the other side.
Custom Data Objects Auxiliary data tables (CDOs) linked to Contacts for records like event registrations or purchases; synced via the Bulk API so nurture campaigns can branch on them. GL Accounts Chart of accounts read for transaction mapping across integrations. Custom Data Objects is specific to Eloqua and GL Accounts to Sage 300 — each maps to any object or custom field on the other side.
Activities Engagement events (email opens, clicks, form submits, bounces, page views, subscribes/unsubscribes) exported through the Bulk API activities export; read-only feed for scoring and attribution. Journal Batches GL entries staged in batches that must be posted; a common write target for external systems. Activities is specific to Eloqua and Journal Batches to Sage 300 — each maps to any object or custom field on the other side.
Campaigns Multi-step campaign-canvas assets managed through the Application REST API; campaign membership and response data read out for attribution reporting. Order Entry Orders Sales orders written from e-commerce or EDI feeds. Campaigns is specific to Eloqua and Order Entry Orders to Sage 300 — 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. Purchase Orders Procurement documents read for spend visibility and receiving. Emails is specific to Eloqua and Purchase Orders to Sage 300 — each maps to any object or custom field on the other side.

How changes propagate between Eloqua and Sage 300

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 Sage 300 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 applied to Sage 300 as a row-level write, with types converted between the two schemas.

Sage 300 Eloqua Interval-based propagation

DetectionStacksync polls Sage 300 for changes on an incremental schedule, reading only records changed since the previous pass. Scheduled polling.

DeliveryEach detected change is written to Eloqua 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.
