Why teams connect Bill and Gong

Sync customers, invoices, and payment status between Bill and Gong in real time, so sales sees the money and finance sees the relationship.

Finance and sales describe the same customers in different systems. Gong knows the relationship: who the contacts are and what is in motion with the account. Bill knows the money: what was invoiced, what was paid, what is overdue. When the two are connected only by exports, each side works partly blind.

Stacksync links Bills, Vendors, Invoices, Customers in Bill to Trackers & Scorecards, CRM Objects, Library, Data Privacy (Erasure) in Gong with bi-directional, real-time sync. New customers, updated billing details, invoice status, and payment activity move in whichever direction you configure, field by field, with conflicts resolved by rules you set. The result is one version of each customer, visible from both sides.

Common use cases

  • 01 Read approved Bills and their line items into a Postgres warehouse for spend, accrual, and cash-flow reporting without CSV exports.
  • 02 Sync Customers and Invoices from BILL AR into a CRM or ERP so sales and finance see billing and payment status on the account.
  • 03 Import externally recorded dialer or web-conference calls into Gong via POST /v2/calls so they get transcribed and analyzed like native Gong calls.
  • 04 Upload warehouse- or CRM-derived Accounts, Opportunities, and stages into Gong through the CRM integration API so deal context shows alongside conversations.

Common sync patterns

Billing detail changes flow back

When a contact or address is corrected in Gong, Bill gets the update before the next invoice goes out.

Collections with context

Finance sees the account owner and relationship history from Gong when chasing a balance, and sales sees that the chase is happening.

Where Gong tracks deals: closed-won creates the finance record

A won opportunity creates or updates the customer in Bill with the right billing details, so invoicing starts without re-keying.

What you can sync between Bill and Gong

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 Gong objects How this pairing syncs
Customers AR customer master records; mapped to customer/account records in a CRM or ERP so finance and sales share one view. CRM Objects Accounts, opportunities, stages, and users uploaded into Gong through the CRM integration API so CRM context appears alongside conversations. Write (upload) path. Customers is specific to Bill and CRM Objects to Gong — 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. Library Call-library folders and folder content (curated calls and snippets) read via GET /v2/library/folders and /v2/library/folder-content. Read-only. Payments is specific to Bill and Library to Gong — 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. Data Privacy (Erasure) GDPR/CCPA deletion handled by POST /v2/data-privacy/erase-data-for-email, with data-for-email lookups on the read side; a write path used for compliance deletions. Chart of Accounts is specific to Bill and Data Privacy (Erasure) to Gong — each maps to any object or custom field on the other side.
Bank Accounts Funding and deposit accounts; read to reconcile payments and posted transactions against the ledger. Calls Retrieved via POST /v2/calls/extensive with participants, topics, trackers, scorecards, and media URLs, filtered by fromDateTime/toDateTime; external recordings are also imported via POST /v2/calls with media uploaded via PUT /v2/calls/{id}/media. Read and write. Bank Accounts is specific to Bill and Calls to Gong — each maps to any object or custom field on the other side.
Vendor Credits and Credit Memos AP and AR adjustments applied against bills and invoices; synced so balances stay accurate on both sides. Transcripts Speaker-attributed, timestamped sentences retrieved via POST /v2/calls/transcript for one or more callIds; available only after asynchronous processing completes. Read-only. Vendor Credits and Credit Memos is specific to Bill and Transcripts to Gong — 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. Users Gong users and team members with roles, titles, email, and settings, read via GET /v2/users to map call owners and participants to CRM and warehouse identities. Read-only. Bills is specific to Bill and Users to Gong — each maps to any object or custom field on the other side.

How changes propagate between Bill and Gong

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

Gong Bill Interval-based propagation

DetectionStacksync polls Gong for changes on an incremental schedule, reading only records changed since the previous pass. Polling POST /v2/calls/extensive on fromDateTime/toDateTime.

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.
  • Gong: 3 API calls per second and 10,000 calls per day per company by default; exceeding returns HTTP 429 with a Retry-After header, and limits can be raised by contacting Gong.

How the Bill and Gong connectors work

Bill

Integration surface
REST/JSON (BILL v3 Connect API)
Authentication
Session-based: POST /v3/login with username, password, organizationId, and a developer key (devKey) returns a sessionId that is passed with the devKey as headers on every subsequent call; OAuth is available for partner/embedded apps
Change detection
Webhook event subscriptions (POST /v3/subscriptions) for bills, vendors, payments, invoices, and bank accounts, with polling on createdTime/updatedTime list filters as the fallback
Capabilities

Rate limits
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.

Gong

Integration surface
REST API on api.gong.io/v2 - retrieval endpoints (calls, transcript, users, stats, settings, library, logs) plus write endpoints for importing calls, uploading CRM data, and data-privacy erasure
Authentication
Basic authorization header combining an Access Key and Access Key Secret (created by a Gong technical admin, base64-encoded as key:secret); OAuth 2.0 Bearer tokens are supported for marketplace apps
Change detection
Polling POST /v2/calls/extensive on fromDateTime/toDateTime; the public API exposes no outbound webhooks or CDC, though a Gong admin can configure a product-side automation Rule that POSTs matching calls to a URL. Transcripts and analysis appear only after asynchronous processing.
Capabilities

Rate limits
3 API calls per second and 10,000 calls per day per company by default; exceeding returns HTTP 429 with a Retry-After header, and limits can be raised by contacting Gong.
