Why teams connect Bill and Google Cloud SQL

Work with Bill's financial data straight from Google Cloud SQL: read it with ordinary queries, write to it from your own code, and let Stacksync keep both sides consistent.

Engineers need finance data more often than finance systems make it easy to get: for internal tools, reporting services, or logic that reacts to invoices and payments. Working through the vendor API means rate limits, pagination, and glue code that has to be maintained forever.

Stacksync mirrors Customers, Payments, Chart of Accounts, Bank Accounts from Bill into Instances, Databases, Schemas, Tables in Google Cloud SQL and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Google Cloud SQL, and rows your code writes or updates flow back into Bill with validation, so the finance system stays the system of record.

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 Keep an internal admin application backed by Cloud SQL consistent with an ERP or billing system.
  • 04 Migrate from a self-managed database by syncing Cloud SQL and the legacy system during cutover.

Common sync patterns

Internal tools without API plumbing

Build dashboards and back-office tools directly on Google Cloud SQL; Stacksync handles the API calls, rate limits, and retries against Bill.

Write back safely

Updates written to the synced tables in Google Cloud SQL propagate into Bill, so automations can create or correct finance records without custom integration code.

React to financial events

Changes in Bill appear in Google Cloud SQL as row changes, so you can trigger downstream logic with the database tooling you already use.

What you can sync between Bill and Google Cloud SQL

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 Google Cloud SQL objects How this pairing syncs
Payments Outgoing vendor payments and received customer payments; read for reconciliation and created to schedule bill pay. Views Read-only sources for shaping data before syncing it out. Payments is specific to Bill and Views to Google Cloud SQL — 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. Transaction logs MySQL binlog or PostgreSQL WAL, the source for log-based change capture. Chart of Accounts is specific to Bill and Transaction logs to Google Cloud SQL — 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. Instances The managed MySQL, PostgreSQL, or SQL Server server a sync connects to. Bank Accounts is specific to Bill and Instances to Google Cloud SQL — 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. Databases Scope the tables included in a sync configuration. Vendor Credits and Credit Memos is specific to Bill and Databases to Google Cloud SQL — 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. Schemas Namespace tables in PostgreSQL and SQL Server instances. Bills is specific to Bill and Schemas to Google Cloud SQL — 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. Tables Mapped directly to sync targets; schema changes can be propagated. Vendors is specific to Bill and Tables to Google Cloud SQL — each maps to any object or custom field on the other side.

How changes propagate between Bill and Google Cloud SQL

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 Google Cloud SQL 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 applied to Google Cloud SQL as a row-level write, with types converted between the two schemas.

Google Cloud SQL Bill Sub-second propagation

DetectionChanges in Google Cloud SQL are captured at the source via change data capture — no polling loop against its API. Engine-dependent log-based CDC: MySQL binlog, PostgreSQL logical replication, SQL Server change tracking.

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.
  • Google Cloud SQL: Constrained by instance size and connection limits rather than API quotas.
