Why teams connect Azure Active Directory and Bill

Keep the people who can act on financial records in Bill matched to their identities in Azure Active Directory, so access is provisioned, updated, and revoked in real time.

Bill runs the money — the ledgers, invoices, budgets, and payments — and every one of those actions is taken by a person with a login. Azure Active Directory 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 Vendor Credits and Credit Memos, Bills, Vendors, Invoices in Bill aligned with Directory roles, Devices, Users, Groups in Azure Active Directory, 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.

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 Provision and deprovision Entra ID Users and Group memberships from an HR system of record so account enablement follows employment status.
  • 04 Sync manager, department, and jobTitle from an HRIS back onto Entra ID User attributes to keep dynamic groups and Conditional Access accurate.

Common sync patterns

One user roster across both systems

People, their status, and their contact details stay matched between Bill and Azure Active Directory, so the finance system's login list reflects who actually works here instead of drifting out of date.

Group and role membership drives finance permissions

A person's group or role in Azure Active Directory maps to their permission set in Bill, so who can approve, post, or view is governed from one place instead of maintained twice.

Access reviews backed by live data

Because the user list in Bill matches the identity source in Azure Active Directory in real time, access certifications and SOX-style reviews start from current membership rather than a stale spreadsheet.

What you can sync between Azure Active Directory and Bill

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.

Azure Active Directory objects Bill objects How this pairing syncs
Applications App registrations under /applications; usually read into a database or CMDB for app ownership and credential-expiry tracking. Customers AR customer master records; mapped to customer/account records in a CRM or ERP so finance and sales share one view. Applications is specific to Azure Active Directory and Customers to Bill — each maps to any object or custom field on the other side.
Service principals /servicePrincipals (enterprise apps) plus appRoleAssignments; read for app inventory and access-posture reporting. Payments Outgoing vendor payments and received customer payments; read for reconciliation and created to schedule bill pay. Service principals is specific to Azure Active Directory and Payments to Bill — each maps to any object or custom field on the other side.
Directory roles /directoryRoles and roleManagement assignments; read for privileged-access reviews, with role-assignment writes where the granted scopes permit. Chart of Accounts GL accounts used to code bills and invoices; typically mastered in the accounting system and written into BILL for consistent coding. Directory roles is specific to Azure Active Directory and Chart of Accounts to Bill — each maps to any object or custom field on the other side.
Devices /devices registered or joined to the tenant; typically read-only into asset and security databases. Bank Accounts Funding and deposit accounts; read to reconcile payments and posted transactions against the ledger. Devices is specific to Azure Active Directory and Bank Accounts to Bill — each maps to any object or custom field on the other side.
Users /users in Microsoft Graph; synced two-way — profile attributes, accountEnabled, and assignedLicenses are read out while provisioning writes (create, update, disable, delete) are pushed back. Vendor Credits and Credit Memos AP and AR adjustments applied against bills and invoices; synced so balances stay accurate on both sides. Users is specific to Azure Active Directory and Vendor Credits and Credit Memos to Bill — each maps to any object or custom field on the other side.
Groups /groups covering security and Microsoft 365 groups; created, updated, and deleted through Graph, and read into warehouses for entitlement reporting. 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. Groups is specific to Azure Active Directory and Bills to Bill — each maps to any object or custom field on the other side.

How changes propagate between Azure Active Directory and Bill

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.

Azure Active Directory Bill Sub-second propagation

DetectionAzure Active Directory notifies Stacksync of record changes through webhook events. Microsoft Graph delta query (deltaLink tokens returning only changed users and groups, with @removed deletions) paired with change-notification.

DeliveryEach detected change is written to Bill through its API, with automatic retries and rate-limit backoff.

Bill Azure Active Directory 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 Azure Active Directory through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Azure Active Directory: Resource-unit throttling: roughly 8,000 ResourceUnits per 10 seconds per app for reads on tenants over 500 users, writes near 3,000 requests per 2.5 minutes; 429 responses include a Retry-After header.
  • 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.
