Why teams connect Bill and Oracle DB

Work with Bill's financial data straight from Oracle DB: 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 Schemas, Sequences, PL/SQL procedures and packages, Partitions in Oracle DB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Oracle DB, 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 Write changes from SaaS apps back into Oracle so PL/SQL jobs and reports run on current data.
  • 04 Log-based replication of order and inventory tables into an analytics warehouse instead of nightly batch dumps.

Common sync patterns

Internal tools without API plumbing

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

Write back safely

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

React to financial events

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

What you can sync between Bill and Oracle DB

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 Oracle DB objects How this pairing syncs
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. Sequences Key generators to respect when external systems insert rows Bills is specific to Bill and Sequences to Oracle DB — 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. PL/SQL procedures and packages In-database logic that can consume or transform synced data Vendors is specific to Bill and PL/SQL procedures and packages to Oracle DB — 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. Partitions Physical subdivisions relevant when replicating high-volume tables Invoices is specific to Bill and Partitions to Oracle DB — 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. JSON columns Document data stored in the converged engine and synced alongside relational rows Customers is specific to Bill and JSON columns to Oracle DB — 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. Tables The primary read/write surface for row-level sync over SQL Payments is specific to Bill and Tables to Oracle DB — 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. Views Curated read-only projections exposed to downstream consumers Chart of Accounts is specific to Bill and Views to Oracle DB — each maps to any object or custom field on the other side.

How changes propagate between Bill and Oracle DB

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

Oracle DB Bill Sub-second propagation

DetectionChanges in Oracle DB are captured at the source via change data capture — no polling loop against its API. Log-based CDC from redo logs via LogMiner or GoldenGate, or trigger and timestamp polling.

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.
  • Oracle DB: Throughput bounded by database resources rather than API quotas.
