Why teams connect Cvent and Sage 300

Feed the real customer, order, and revenue records from Sage 300 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. Sage 300 holds exactly that: GL Accounts, Journal Batches, Order Entry Orders, Purchase 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 GL Accounts, Journal Batches, Order Entry Orders, Purchase Orders in Sage 300 with Attendees and Registrations, Sessions, Speakers, Exhibitors 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 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 Write web and EDI orders into Order Entry and return order status to the source channel.
  • 02 Replicate GL, AR, and AP detail to a warehouse for consolidated multi-company reporting.
  • 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 Sage 300 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 Sage 300, 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.

What you can sync between Cvent 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.

Cvent objects Sage 300 objects How this pairing syncs
Surveys Survey definitions and responses; read out to a warehouse for post-event feedback analysis alongside attendance data. Journal Batches GL entries staged in batches that must be posted; a common write target for external systems. Surveys is specific to Cvent and Journal Batches to Sage 300 — each maps to any object or custom field on the other side.
Budgets Event budget line items; read into a finance database or ERP to reconcile planned versus actual event spend. Order Entry Orders Sales orders written from e-commerce or EDI feeds. Budgets is specific to Cvent and Order Entry Orders to Sage 300 — each maps to any object or custom field on the other side.
Events Top-level event containers created and updated through the Events endpoints; read out for reporting and written to provision events from an external system. Purchase Orders Procurement documents read for spend visibility and receiving. Events is specific to Cvent and Purchase Orders to Sage 300 — each maps to any object or custom field on the other side.
Contacts Account-wide people database spanning every event; synced two-way with a CRM or warehouse as the shared audience source of truth via the Create Contacts endpoint. Inventory Items Item master with costing and quantities, synced to storefronts and WMS. Contacts is specific to Cvent and Inventory Items to Sage 300 — each maps to any object or custom field on the other side.
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. AR Invoices and Receipts Billing and payment records replicated for cash and revenue reporting. Attendees and Registrations is specific to Cvent and AR Invoices and Receipts to Sage 300 — 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. AR Customers Receivables customer master synced to CRMs and billing tools. Sessions is specific to Cvent and AR Customers to Sage 300 — each maps to any object or custom field on the other side.

How changes propagate between Cvent 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.

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

Sage 300 Cvent 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 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.
