Why teams connect Bill and Eloqua
Put revenue reality behind every campaign: Bill and Eloqua 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; Eloqua 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 Payments, Chart of Accounts, Bank Accounts, Vendor Credits and Credit Memos in Bill with Contact Lists and Segments, Contacts, Accounts, Custom Data Objects in Eloqua 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 Add or remove Contacts from shared Contact Lists and Segments based on lifecycle stage computed downstream in a database.
- 04 Two-way sync Contacts between Eloqua and a Postgres or warehouse table, matched on email, so ops teams query and update marketing profiles in SQL while marketers keep working in Eloqua.
Common sync patterns
Revenue and billing signals reach the audience
Plan tier, spend, or payment status from Bill lands on the matching record in Eloqua, so segments and targeting reflect who actually pays and how much.
One customer and contact list
Where both systems keep customer or contact records, an edit on either side propagates to the other, ending dual maintenance and the drift it creates.
Where Eloqua captures new people: clean records flow to finance
Registrants, form fills, or leads created in Eloqua create or update the matching customer or contact in Bill, so billing and reporting start from accurate details without re-entry.
What you can sync between Bill and Eloqua
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 | Eloqua objects | How this pairing syncs | |
|---|---|---|---|
| Vendor Credits and Credit Memos AP and AR adjustments applied against bills and invoices; synced so balances stay accurate on both sides. | 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. | Vendor Credits and Credit Memos is specific to Bill and Activities to Eloqua — each maps to any object or custom field on the other side. | |
| 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. | Campaigns Multi-step campaign-canvas assets managed through the Application REST API; campaign membership and response data read out for attribution reporting. | Bills is specific to Bill and Campaigns to Eloqua — 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. | Emails Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync. | Vendors is specific to Bill and Emails to Eloqua — 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. | 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. | Invoices is specific to Bill and Forms and Form Submits to Eloqua — 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. | 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. | Customers is specific to Bill and Contact Lists and Segments to Eloqua — 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. | 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. | Payments is specific to Bill and Contacts to Eloqua — each maps to any object or custom field on the other side. |
How changes propagate between Bill and Eloqua
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 Eloqua 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 Eloqua through its API, with automatic retries and rate-limit backoff.
Eloqua Bill 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 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.
- 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.

FAQ
Bill and Eloqua integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Bill and Eloqua: authenticate both systems, choose the objects to sync (such as Bill's Vendor Credits and Credit Memos and Bills), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Bill: Rate limits are enforced per developer key: 20,000 requests per hour, login capped at 200 per hour, and a maximum of 3 concurrent requests per developer key per organization. Eloqua: Contact records are keyed on email address; imports upsert against email as the default match key, so records without a valid email cannot be matched. Stacksync's field mapping accounts for these differences between Bill and Eloqua without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Bill and Eloqua records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Bill and Eloqua connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Bill–Eloqua integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Bill and Eloqua. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
