Why teams connect Bill and OCI Database (Oracle Cloud)

Work with Bill's financial data straight from OCI Database (Oracle Cloud): 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 Invoices, Customers, Payments, Chart of Accounts from Bill into Materialized views, Schemas, Sequences, PL/SQL procedures and packages in OCI Database (Oracle Cloud) and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against OCI Database (Oracle Cloud), 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 Replicate operational tables from OCI to an analytics warehouse with log-based CDC instead of nightly batch dumps.
  • 04 Run on-prem Oracle and OCI side by side during a cloud migration while keeping both ends writable.

Common sync patterns

Internal tools without API plumbing

Build dashboards and back-office tools directly on OCI Database (Oracle Cloud); Stacksync handles the API calls, rate limits, and retries against Bill.

Write back safely

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

React to financial events

Changes in Bill appear in OCI Database (Oracle Cloud) as row changes, so you can trigger downstream logic with the database tooling you already use.

What you can sync between Bill and OCI Database (Oracle Cloud)

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 OCI Database (Oracle Cloud) objects How this pairing syncs
Invoices Accounts-receivable invoices sent to customers; created and read via /v3/invoices to keep billing status aligned with the ERP or CRM. PL/SQL procedures and packages Server-side logic that can react to synced data or transform it in place Invoices is specific to Bill and PL/SQL procedures and packages to OCI Database (Oracle Cloud) — 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 collections Document-style storage in the converged engine, synced alongside relational tables Customers is specific to Bill and JSON collections to OCI Database (Oracle Cloud) — 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. Partitions Physical table subdivisions relevant when replicating large fact tables Payments is specific to Bill and Partitions to OCI Database (Oracle Cloud) — 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. Tables The primary sync surface; rows are read and written directly over SQL Chart of Accounts is specific to Bill and Tables to OCI Database (Oracle Cloud) — 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. Views Read-only projections used to expose curated subsets to downstream systems Bank Accounts is specific to Bill and Views to OCI Database (Oracle Cloud) — 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. Materialized views Precomputed result sets sometimes used as stable read sources for replication Vendor Credits and Credit Memos is specific to Bill and Materialized views to OCI Database (Oracle Cloud) — each maps to any object or custom field on the other side.

How changes propagate between Bill and OCI Database (Oracle Cloud)

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 OCI Database (Oracle Cloud) 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 OCI Database (Oracle Cloud) as a row-level write, with types converted between the two schemas.

OCI Database (Oracle Cloud) Bill Sub-second propagation

DetectionChanges in OCI Database (Oracle Cloud) are captured at the source via change data capture — no polling loop against its API. Log-based CDC from redo logs (LogMiner or GoldenGate), or 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.
  • OCI Database (Oracle Cloud): Throughput bounded by instance sizing rather than API quotas.
