Why teams connect Bill and Gainsight
Connect the financial records in Bill with the work happening in Gainsight, so both stay current without exports or copy-paste.
Bill holds the financial truth: who the customers are, what they were billed, what they paid. Gainsight is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.
Stacksync keeps Customers, Payments, Chart of Accounts, Bank Accounts in Bill and Scorecard Fact, Timeline Activity, Success Plan, Task and Playbook in Gainsight in sync, bi-directionally and in real time. Whatever records Gainsight keeps and whatever events it produces, the overlap with Bill is mapped field by field, and a change on either side shows up on the other within seconds.
There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.
Common use cases
- 01 Sync Customers and Invoices from BILL AR into a CRM or ERP so sales and finance see billing and payment status on the account.
- 02 Write Vendors created during ERP onboarding into BILL so new payees are ready to pay without manual re-entry.
- 03 Read Timeline Activities and Success Plan objectives into a reporting database for churn, QBR, and CSM-productivity dashboards.
- 04 Keep Relationship records aligned with a billing system or ERP so multi-product customers map to the correct contracts and invoices.
Common sync patterns
Where Gainsight tracks people or companies: one identity
A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.
Where Gainsight handles customer conversations: billing context in view
Front-line teams see invoice and payment status from Bill next to the customer they are helping, without logging into the finance system.
Where Gainsight collects payments or triggers charges: events land in Bill
Payment and charge activity flows into Bill as it happens, so the books reflect reality without manual reconciliation.
What you can sync between Bill and Gainsight
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 | Gainsight 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. | Relationship Sub-units within a company for multi-product or multi-team accounts; synced so each maps to the right contract in billing or an ERP. | Customers is specific to Bill and Relationship to Gainsight — 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. | CTA (Call to Action) Risk and expansion alerts that drive CSM plays; often synced to ticketing or project tools so follow-up work is tracked where teams operate. | Payments is specific to Bill and CTA (Call to Action) to Gainsight — 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. | Scorecard Fact Health scores and measures per Company or Relationship; usage metrics from a warehouse are written in so scores reflect live telemetry. | Chart of Accounts is specific to Bill and Scorecard Fact to Gainsight — 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. | Timeline Activity Logged calls, emails, and notes; usually read out into a reporting database for QBR and churn analysis. | Bank Accounts is specific to Bill and Timeline Activity to Gainsight — 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. | Success Plan Account objectives with associated tasks; read out for reporting or synced with project tools tracking onboarding and adoption. | Vendor Credits and Credit Memos is specific to Bill and Success Plan to Gainsight — 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. | Task and Playbook Cockpit tasks generated from CTAs and playbooks; synced with Jira or Asana so execution happens in the team's own tool. | Bills is specific to Bill and Task and Playbook to Gainsight — each maps to any object or custom field on the other side. |
How changes propagate between Bill and Gainsight
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 Gainsight 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 Gainsight through its API, with automatic retries and rate-limit backoff.
Gainsight Bill Interval-based propagation
DetectionStacksync polls Gainsight for changes on an incremental schedule, reading only records changed since the previous pass. Polling on the ModifiedDate (GS Modified Date) system field, which is filterable and sortable on every object.
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.
- Gainsight: Synchronous APIs are capped near 100 calls/min and 50,000/day; the asynchronous Bulk API allows 10 calls/hour and 100/day. Both are fixed-window limits, and the applicable per-hour and per-day limits are returned in the x-ratelimit-limit response header.

FAQ
Bill and Gainsight integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Bill and Gainsight: authenticate both systems, choose the objects to sync (such as Bill's Customers and Payments), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
On the Bill side: Customers, Payments, Chart of Accounts, Bank Accounts, plus custom fields where Bill exposes them. On the Gainsight side: Scorecard Fact, Timeline Activity, Success Plan, Task and Playbook. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Bill and Gainsight: Where Gainsight tracks people or companies: one identity; Where Gainsight handles customer conversations: billing context in view; Where Gainsight collects payments or triggers charges: events land in Bill. A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.

Stacksync manages authentication, retries, and rate limits on both sides.
-
Bill: BILL exposes separate AP and AR object sets plus a distinct Spend & Expense API that uses its own token and a lower 60-calls-per-minute limit. Gainsight: Person records associate to Company via the Company Person object and to Relationship via Relationship Person; those junctions must be maintained for contacts to resolve correctly. Stacksync's field mapping accounts for these differences between Bill and Gainsight without custom code.
