Why teams connect Bill and Google AlloyDB

Work with Bill's financial data straight from Google AlloyDB: 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 Bank Accounts, Vendor Credits and Credit Memos, Bills, Vendors from Bill into Materialized Views, Indexes, Sequences, Replication Slots in Google AlloyDB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Google AlloyDB, 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 Read Payments and payment status into a reconciliation database once bills are marked paid in BILL.
  • 02 Read approved Bills and their line items into a Postgres warehouse for spend, accrual, and cash-flow reporting without CSV exports.
  • 03 Use logical replication to feed AlloyDB changes into warehouses or event pipelines without batch jobs.
  • 04 Consolidate SaaS data into AlloyDB and serve analytics from its columnar engine without a separate OLAP store.

Common sync patterns

Write back safely

Updates written to the synced tables in Google AlloyDB 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 AlloyDB as row changes, so you can trigger downstream logic with the database tooling you already use.

Query finance data like any other data

Customers, invoices, and payments from Bill live in Google AlloyDB as regular tables or collections your team can join, index, and query.

What you can sync between Bill and Google AlloyDB

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 AlloyDB objects How this pairing syncs
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. Materialized Views Precomputed aggregates refreshed and synced outward on a schedule. Vendors is specific to Bill and Materialized Views to Google AlloyDB — 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. Indexes Keep sync key lookups fast on high-volume tables. Invoices is specific to Bill and Indexes to Google AlloyDB — 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. Sequences ID generation relevant when external systems insert rows. Customers is specific to Bill and Sequences to Google AlloyDB — 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. Replication Slots Logical replication artifacts that back log-based change capture. Payments is specific to Bill and Replication Slots to Google AlloyDB — 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. Databases Standard PostgreSQL databases within an AlloyDB cluster that syncs connect to. Chart of Accounts is specific to Bill and Databases to Google AlloyDB — 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. Schemas Namespaces used to separate synced SaaS data from application tables. Bank Accounts is specific to Bill and Schemas to Google AlloyDB — each maps to any object or custom field on the other side.

How changes propagate between Bill and Google AlloyDB

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 AlloyDB 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 AlloyDB as a row-level write, with types converted between the two schemas.

Google AlloyDB Bill Sub-second propagation

DetectionChanges in Google AlloyDB are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication.

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 AlloyDB: No API-style rate limits; throughput is bounded by instance size.
