Why teams connect Bill and Cvent

Put revenue reality behind every campaign: Bill and Cvent share the same customers, contacts, and billing status in real time, in both directions.

Bill records the money — who pays, how much, and whether they are current; Cvent decides who hears from the business and what they hear. The two overlap wherever the same customers and contacts matter to both, and when that overlap is bridged by CSV exports or an overnight batch, campaigns target on stale billing data and finance works from lists marketing has already changed underneath it.

Stacksync syncs Chart of Accounts, Bank Accounts, Vendor Credits and Credit Memos, Bills in Bill with Attendees and Registrations, Sessions, Speakers, Exhibitors in Cvent field by field, in real time, and in both directions. You decide which system owns which fields — finance keeps the revenue and payment truth, marketing keeps consent and engagement — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Write Vendors created during ERP onboarding into BILL so new payees are ready to pay without manual re-entry.
  • 02 Read Payments and payment status into a reconciliation database once bills are marked paid in BILL.
  • 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

Where Cvent captures new people: clean records flow to finance

Registrants, form fills, or leads created in Cvent create or update the matching customer or contact in Bill, so billing and reporting start from accurate details without re-entry.

Where Bill tracks lifecycle state: keep Cvent current

Trial, renewal, churn, or payment state from Bill updates the contact in Cvent, so lifecycle campaigns and audience suppression run on current billing reality.

Consent and contact details stay aligned

Email, phone, address, and opt-out flags kept in either system stay consistent in the other, so every send and record honors the latest preferences.

What you can sync between Bill and Cvent

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.

Bill objects Cvent objects How this pairing syncs
Bills Accounts-payable amounts owed to vendors, with bill line items; read and created via /v3/bills and pulled incrementally by filtering on createdTime/updatedTime. Speakers Speaker records tied to an event; synced two-way with a speaker database or CMS, with an updatedDate on each record for incremental pulls. Bills is specific to Bill and Speakers to Cvent — each maps to any object or custom field on the other side.
Vendors Payee master records; synced two-way with vendor/supplier tables in an ERP or accounting system so new payees don't have to be re-keyed. Exhibitors Exhibitor and sponsor records; synced to a CRM or database to track booth, sponsorship, and lead-capture data per event. Vendors is specific to Bill and Exhibitors to Cvent — each maps to any object or custom field on the other side.
Invoices Accounts-receivable invoices sent to customers; created and read via /v3/invoices to keep billing status aligned with the ERP or CRM. Surveys Survey definitions and responses; read out to a warehouse for post-event feedback analysis alongside attendance data. Invoices is specific to Bill and Surveys to Cvent — each maps to any object or custom field on the other side.
Customers AR customer master records; mapped to customer/account records in a CRM or ERP so finance and sales share one view. Budgets Event budget line items; read into a finance database or ERP to reconcile planned versus actual event spend. Customers is specific to Bill and Budgets to Cvent — each maps to any object or custom field on the other side.
Payments Outgoing vendor payments and received customer payments; read for reconciliation and created to schedule bill pay. 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. Payments is specific to Bill and Events to Cvent — each maps to any object or custom field on the other side.
Chart of Accounts GL accounts used to code bills and invoices; typically mastered in the accounting system and written into BILL for consistent coding. 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. Chart of Accounts is specific to Bill and Contacts to Cvent — each maps to any object or custom field on the other side.

How changes propagate between Bill and Cvent

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.

Bill Cvent Sub-second propagation

DetectionBill notifies Stacksync of record changes through webhook events. Webhook event subscriptions (POST /v3/subscriptions) for bills, vendors, payments, invoices, and bank accounts, with polling on.

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

Cvent Bill 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 Bill through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Bill: 20,000 requests per developer key per hour; login (POST /v3/login) capped at 200/hour; maximum 3 concurrent requests per developer key per organization. Spend & Expense API is a separate token at 60 calls/token/minute.
  • 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.
