Why teams connect Bill and Materialize
Land the financial records from Bill in Materialize 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 Payments, Chart of Accounts, Bank Accounts, Vendor Credits and Credit Memos from Bill into tables in Materialize in real time, and the connection works in both directions: values computed in Materialize 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 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 Read computed view results back into a CRM or application database as derived fields.
- 04 Drive alerting and operational tooling from SUBSCRIBE change streams instead of scheduled queries.
Common sync patterns
Write-back of computed fields
Scores or segments computed in Materialize, 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 Materialize 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 Materialize as queryable tables, current within seconds instead of a day behind.
What you can sync between Bill and Materialize
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 | Materialize objects | How this pairing syncs | |
|---|---|---|---|
| Vendor Credits and Credit Memos AP and AR adjustments applied against bills and invoices; synced so balances stay accurate on both sides. | Schemas & Databases Namespaces that organize objects a sync targets. | Vendor Credits and Credit Memos is specific to Bill and Schemas & Databases to Materialize — 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. | Tables User-managed tables that accept INSERT/UPDATE/DELETE from sync pipelines. | Bills is specific to Bill and Tables to Materialize — 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. | Sources Ingestion points (Kafka, Postgres CDC, MySQL CDC, webhook) that feed external data into Materialize. | Vendors is specific to Bill and Sources to Materialize — 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. | Materialized Views Incrementally maintained query results that syncs read as continuously up-to-date datasets. | Invoices is specific to Bill and Materialized Views to Materialize — 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. | Sinks Outbound connections that emit view changes to Kafka topics. | Customers is specific to Bill and Sinks to Materialize — 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. | Indexes In-memory arrangements that make view reads fast for serving workloads. | Payments is specific to Bill and Indexes to Materialize — each maps to any object or custom field on the other side. |
How changes propagate between Bill and Materialize
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 Materialize 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 Materialize as a row-level write, with types converted between the two schemas.
Materialize Bill Sub-second propagation
DetectionChanges in Materialize are captured at the source via change data capture — no polling loop against its API. SUBSCRIBE queries stream row-level changes of any view or table to the client.
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.

FAQ
Bill and Materialize integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Bill and Materialize: authenticate both systems, choose the objects to sync (such as Bill's Vendor Credits and Credit Memos and Bills), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Bill: List endpoints support filtering and sorting on createdTime and updatedTime with ISO 8601 date-time ranges, which sync engines use to pull only incremental changes. Materialize: It ingests CDC from Postgres and MySQL and streams from Kafka as first-class sources. Stacksync's field mapping accounts for these differences between Bill and Materialize without custom code.
-
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 Materialize records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Bill and Materialize connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Bill–Materialize integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Bill and Materialize. 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 Materialize: SUBSCRIBE queries stream row-level changes of any view or table to the client. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
