Why teams connect Bill and Oracle Fusion Cloud HCM

Keep the employee, department, and cost records that Bill and Oracle Fusion Cloud HCM share consistent in real time, so the finance system and the people system stop drifting apart.

Bill runs the money side of the company: who gets paid, what it costs, and which part of the business the cost belongs to. Oracle Fusion Cloud HCM runs the people side: who works here, which team they sit in, and how their employment changes over time. The two overlap on the same people and the same org structure, because every employee is also a payee and every department is also a cost center. When that overlap is maintained by hand, a new hire, a transfer, or a termination has to be keyed twice, and the two systems start to disagree about who is active and where the cost lands.

Stacksync syncs Chart of Accounts, Bank Accounts, Vendor Credits and Credit Memos, Bills in Bill with Jobs, Positions, Departments (Organizations), Locations in Oracle Fusion Cloud HCM bi-directionally and in real time. A person added, updated, or deactivated on either side appears on the other within seconds, with field-level mapping and conflict resolution in place of CSV exports and nightly batch jobs.

That matters most when money follows a people event. A hire that finance can pay, a leaver whose access ends, a transfer that redirects cost to the right team, all happen from one change instead of two, so headcount and spend reconcile from the same set of records.

Common use cases

  • 01 Write Vendors created during ERP onboarding into BILL so new payees are ready to pay without manual re-entry.
  • 02 Read Payments and payment status into a reconciliation database once bills are marked paid in BILL.
  • 03 Replicate Grades and Salaries into a warehouse for compensation and headcount analytics without exporting HDL files.
  • 04 Keep Positions and Departments aligned between Oracle HCM and a finance/ERP system so cost centers and reporting structures match.

Common sync patterns

People-driven costs land in finance

Compensation, reimbursements, or other costs tied to a person on the Oracle Fusion Cloud HCM side flow into Bill for posting, so the books reflect what people actually cost without manual re-entry.

New person becomes a known record in finance

When someone is added in Oracle Fusion Cloud HCM, a matching employee or payee record appears in Bill, ready for payroll, expenses, or cost allocation without anyone rekeying the details.

One employee identity

A person's name, ID, or contact details corrected in either system update the other, so finance and HR reference the same person instead of maintaining two versions.

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 Fusion Cloud HCM 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. Assignments Child of a worker's work relationship carrying job, position, department, location, grade, and manager; effective-dated, so writes go through PATCH with an effective date. Invoices is specific to Bill and Assignments to Oracle Fusion Cloud HCM — 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. Jobs Job catalog reference data; commonly read out to align titles and job codes in a warehouse or written to keep downstream systems consistent. Customers is specific to Bill and Jobs to Oracle Fusion Cloud HCM — 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. Positions Position-management records used where positions control headcount; synced to keep vacancy and reporting structures aligned with finance/ERP. Payments is specific to Bill and Positions to Oracle Fusion Cloud HCM — 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. Departments (Organizations) Org-structure records that define cost centers and reporting lines; typically mastered in HCM and read into other systems. Chart of Accounts is specific to Bill and Departments (Organizations) to Oracle Fusion Cloud HCM — 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. Locations Physical work locations referenced by assignments; synced so downstream provisioning and directory tools resolve the same location codes. Bank Accounts is specific to Bill and Locations to Oracle Fusion Cloud HCM — 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. Grades and Salaries Grade, grade-rate, and worker compensation records; usually read out for compensation and headcount analytics, and written back for corrections. Vendor Credits and Credit Memos is specific to Bill and Grades and Salaries to Oracle Fusion Cloud HCM — each maps to any object or custom field on the other side.

How changes propagate between Bill and Oracle Fusion Cloud HCM

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 Fusion Cloud HCM 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 Oracle Fusion Cloud HCM through its API, with automatic retries and rate-limit backoff.

Oracle Fusion Cloud HCM Bill Sub-second propagation

DetectionChanges in Oracle Fusion Cloud HCM are captured at the source via change data capture — no polling loop against its API. Atom feeds expose changes-only feeds for key events (new hire, termination, assignment change).

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 Fusion Cloud HCM: Oracle publishes no fixed per-tenant REST rate limit; pages are capped via limit/offset and Oracle recommends client-side throttling, backoff, and using HDL for mass loads rather than transactional REST.
