Why teams connect Azure Synapse Analytics and Bill

Land the financial records from Bill in Azure Synapse Analytics continuously, and write results back, without building or maintaining a pipeline.

Finance data belongs in the warehouse: revenue, invoices, payments, and customers joined with everything else the business measures. Getting it there usually means an extraction pipeline that breaks quietly and delivers yesterday's numbers.

Stacksync syncs Vendors, Invoices, Customers, Payments from Bill into tables in Azure Synapse Analytics in real time, and the connection works in both directions: values computed in Azure Synapse Analytics can be written back to fields in Bill where you want them operational. Schema changes are handled, API limits are managed, and the sync is something you configure rather than code you maintain.

Common use cases

  • 01 Read approved Bills and their line items into a Postgres warehouse for spend, accrual, and cash-flow reporting without CSV exports.
  • 02 Sync Customers and Invoices from BILL AR into a CRM or ERP so sales and finance see billing and payment status on the account.
  • 03 Load CRM and ERP records into Synapse dedicated SQL pool tables for enterprise reporting.
  • 04 Publish warehouse aggregates (account health scores, LTV) from Synapse back into operational tools like a CRM.

Common sync patterns

Write-back of computed fields

Scores or segments computed in Azure Synapse Analytics, like payment-risk flags or customer tiers, sync back onto records in Bill where the finance team can act on them.

Queryable history for audit and reconciliation

A continuously synced copy in Azure Synapse Analytics gives you a durable, queryable record of financial data for month-end and audit questions.

Finance analytics without ETL

Invoices, payments, and customer records from Bill arrive in Azure Synapse Analytics as queryable tables, current within seconds instead of a day behind.

What you can sync between Azure Synapse Analytics 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 Synapse Analytics objects Bill objects How this pairing syncs
SQL pools Dedicated or serverless compute contexts that determine how and where queries run. 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. SQL pools is specific to Azure Synapse Analytics and Bills to Bill — each maps to any object or custom field on the other side.
Tables (dedicated SQL pool) Distributed warehouse tables that serve as sync destinations for analytics workloads. 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. Tables (dedicated SQL pool) is specific to Azure Synapse Analytics and Vendors to Bill — each maps to any object or custom field on the other side.
External tables Tables over files in the data lake, queried through serverless SQL and often read-only in syncs. Invoices Accounts-receivable invoices sent to customers; created and read via /v3/invoices to keep billing status aligned with the ERP or CRM. External tables is specific to Azure Synapse Analytics and Invoices to Bill — each maps to any object or custom field on the other side.
Views Curated projections used when downstream tools should not read base tables directly. Customers AR customer master records; mapped to customer/account records in a CRM or ERP so finance and sales share one view. Views is specific to Azure Synapse Analytics and Customers to Bill — each maps to any object or custom field on the other side.
Schemas Namespaces that separate staging, integration, and presentation layers. Payments Outgoing vendor payments and received customer payments; read for reconciliation and created to schedule bill pay. Schemas is specific to Azure Synapse Analytics and Payments to Bill — each maps to any object or custom field on the other side.
Materialized views Precomputed aggregates that speed reads of frequently synced result sets. Chart of Accounts GL accounts used to code bills and invoices; typically mastered in the accounting system and written into BILL for consistent coding. Materialized views is specific to Azure Synapse Analytics and Chart of Accounts to Bill — each maps to any object or custom field on the other side.

How changes propagate between Azure Synapse Analytics 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 Synapse Analytics Bill Interval-based propagation

DetectionStacksync polls Azure Synapse Analytics for changes on an incremental schedule, reading only records changed since the previous pass. Polling on watermark columns.

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

Bill Azure Synapse Analytics 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 Synapse Analytics 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.
