Why teams connect Cvent and DEAR Inventory

Feed the real customer, order, and revenue records from DEAR Inventory 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. DEAR Inventory holds exactly that: Suppliers, Stock adjustments and transfers, Assemblies / Production, Locations 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 Suppliers, Stock adjustments and transfers, Assemblies / Production, Locations in DEAR Inventory with Exhibitors, Surveys, Budgets, Events 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 DEAR Inventory.

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 stock levels and product data to e-commerce storefronts and a CRM so sales quotes reflect real availability.
  • 02 Push sale orders from a storefront or CRM into DEAR for fulfillment without manual re-entry.
  • 03 Sync Sessions and Speakers into a content database or agenda app so schedule and speaker changes propagate without manual re-entry.
  • 04 Read Budgets and event financials into an ERP or finance database to reconcile planned versus actual event spend.

Common sync patterns

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 DEAR Inventory 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 DEAR Inventory, so the back office sees them without anyone re-keying.
