Two-way sync
Changes in Bill or Onelogin instantly reflect in both systems. No stale data, no manual imports.
Keep Bill and Onelogin in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
Bill runs the money — the ledgers, invoices, budgets, and payments — and every one of those actions is taken by a person with a login. Onelogin is where those people and their access actually live: who is employed, what team they belong to, and what they are allowed to do. The two systems rarely share customers or transactions, but they share the one thing that governs both — the user. When that overlap is maintained by hand, a departed employee keeps finance access for weeks and a new hire waits on a ticket to get any.
Stacksync keeps Bills, Vendors, Invoices, Customers in Bill aligned with Authentication factors (MFA), Custom user fields, Users, Roles in Onelogin, field by field and in real time. A person added, moved, or deactivated on the identity side updates their matching user in the finance system within seconds, with the role or permission set mapped from the group they belong to. Direction is yours to set: lead provisioning from the directory, or let an HR-owned finance record drive the downstream accounts.
For a finance team, that alignment is an audit control rather than a convenience. When the user list in the books matches the identity source of truth, segregation-of-duties and access reviews start from data that is already correct instead of an export that was current last quarter.
People, their status, and their contact details stay matched between Bill and Onelogin, so the finance system's login list reflects who actually works here instead of drifting out of date.
A person's group or role in Onelogin maps to their permission set in Bill, so who can approve, post, or view is governed from one place instead of maintained twice.
Because the user list in Bill matches the identity source in Onelogin in real time, access certifications and SOX-style reviews start from current membership rather than a stale spreadsheet.
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 | Onelogin objects | How this pairing syncs | |
|---|---|---|---|
| Chart of Accounts GL accounts used to code bills and invoices; typically mastered in the accounting system and written into BILL for consistent coding. | Apps (app instances) Connected SAML/OIDC application configs on the account; create, update, delete, and assign to users and roles - the writable app catalog. | Chart of Accounts is specific to Bill and Apps (app instances) to Onelogin — 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. | Groups Account groups used for mapping and reporting; listed and read through the API, which has no create or update endpoint, so groups are read-only. | Bank Accounts is specific to Bill and Groups to Onelogin — 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. | Mappings (mapping rules) Attribute-driven rules that assign roles and app access; full CRUD via the Mappings API, then reapplied across matching users. | Vendor Credits and Credit Memos is specific to Bill and Mappings (mapping rules) to Onelogin — 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. | Events Audit log of every authentication and admin action; read-only, filtered by since/until, and pushed live through the Event Webhook. | Bills is specific to Bill and Events to Onelogin — 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. | Authentication factors (MFA) Per-user registered MFA factors; enrolled, verified, and removed through the MFA API for lifecycle and security workflows. | Vendors is specific to Bill and Authentication factors (MFA) to Onelogin — 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. | Custom user fields Account-level custom attributes on the User record; read and written alongside the standard user profile fields. | Invoices is specific to Bill and Custom user fields to Onelogin — each maps to any object or custom field on the other side. |
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.
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 Onelogin through its API, with automatic retries and rate-limit backoff.
DetectionOnelogin notifies Stacksync of record changes through webhook events. Event Webhook (Event Broadcaster) posts batches of Event objects to a registered endpoint in near real time.

Real-time sync, workflow automation, event queues, EDI, and monitoring, for every Bill–Onelogin connection.
Changes in Bill or Onelogin instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever Bill or Onelogin data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single Bill or Onelogin record.
Track your Bill ⇄ Onelogin sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between Bill and Onelogin.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate Bill and Onelogin with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the Bill and Onelogin objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between Bill and Onelogin: authenticate both systems, choose the objects to sync (such as Bill's Chart of Accounts and Bank Accounts), map fields visually, and changes propagate both ways in milliseconds — no code required.
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Bill and Onelogin records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Bill and Onelogin connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Bill–Onelogin integration in-house.
Yes — Stacksync ships production-grade connectors for both Bill and Onelogin. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
Change detection on Bill: Webhook event subscriptions (POST /v3/subscriptions) for bills, vendors, payments, invoices, and bank accounts, with polling on createdTime/updatedTime list filters as the fallback. On Onelogin: Event Webhook (Event Broadcaster) posts batches of Event objects to a registered endpoint in near real time; the Events API also supports polling with since/until time filters and pagination for historical backfill. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
On the Bill side: Bills, Vendors, Invoices, Customers, plus custom fields where Bill exposes them. On the Onelogin side: Authentication factors (MFA), Custom user fields, Users, Roles. Stacksync auto-detects both schemas and converts types between the two systems.
