Why teams connect Azure SQL Database and Bill

Work with Bill's financial data straight from Azure SQL Database: 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 Customers, Payments, Chart of Accounts, Bank Accounts from Bill into Rows and columns, Stored procedures, Change tracking / CDC tables, Tables in Azure SQL Database and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Azure SQL Database, 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 Azure SQL tables to a warehouse without building custom CDC pipelines.
  • 04 Consolidate data from several line-of-business apps into one Azure SQL database as an integration hub.

Common sync patterns

Internal tools without API plumbing

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

Write back safely

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

React to financial events

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

What you can sync between Azure SQL Database 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 SQL Database objects Bill objects How this pairing syncs
Tables The primary sync target; rows map one-to-one to records in the paired system. Vendor Credits and Credit Memos AP and AR adjustments applied against bills and invoices; synced so balances stay accurate on both sides. Tables is specific to Azure SQL Database and Vendor Credits and Credit Memos to Bill — each maps to any object or custom field on the other side.
Views Read-only projections used when the sync should expose a curated shape rather than raw tables. 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. Views is specific to Azure SQL Database and Bills to Bill — each maps to any object or custom field on the other side.
Schemas Namespaces that organize tables and control which objects a sync user can reach. 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. Schemas is specific to Azure SQL Database and Vendors to Bill — each maps to any object or custom field on the other side.
Rows and columns Standard relational records with typed columns; primary keys anchor upserts. Invoices Accounts-receivable invoices sent to customers; created and read via /v3/invoices to keep billing status aligned with the ERP or CRM. Rows and columns is specific to Azure SQL Database and Invoices to Bill — each maps to any object or custom field on the other side.
Stored procedures Existing business logic that some teams invoke on write instead of direct table inserts. Customers AR customer master records; mapped to customer/account records in a CRM or ERP so finance and sales share one view. Stored procedures is specific to Azure SQL Database and Customers to Bill — each maps to any object or custom field on the other side.
Change tracking / CDC tables System-maintained change records used to drive incremental sync. Payments Outgoing vendor payments and received customer payments; read for reconciliation and created to schedule bill pay. Change tracking / CDC tables is specific to Azure SQL Database and Payments to Bill — each maps to any object or custom field on the other side.

How changes propagate between Azure SQL Database 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 SQL Database Bill Sub-second propagation

DetectionChanges in Azure SQL Database are captured at the source via change data capture — no polling loop against its API. Change data capture or change tracking, both supported on Azure SQL Database.

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

Bill Azure SQL Database 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 Azure SQL Database as a row-level write, with types converted between the two schemas.

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.
