Why teams connect Bill and TimescaleDB
Work with Bill's financial data straight from TimescaleDB: 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 Invoices, Customers, Payments, Chart of Accounts from Bill into Views, Schemas, Hypertables, Chunks in TimescaleDB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against TimescaleDB, 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 Sync product or IoT telemetry stored in TimescaleDB into a CRM so account teams see usage metrics next to the customer record.
- 04 Replicate subscription and billing events from operational Postgres tables into Timescale hypertables for time-series analysis.
Common sync patterns
Internal tools without API plumbing
Build dashboards and back-office tools directly on TimescaleDB; Stacksync handles the API calls, rate limits, and retries against Bill.
Write back safely
Updates written to the synced tables in TimescaleDB propagate into Bill, so automations can create or correct finance records without custom integration code.
React to financial events
Changes in Bill appear in TimescaleDB as row changes, so you can trigger downstream logic with the database tooling you already use.
What you can sync between Bill and TimescaleDB
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 | TimescaleDB objects | How this pairing syncs | |
|---|---|---|---|
| Bank Accounts Funding and deposit accounts; read to reconcile payments and posted transactions against the ledger. | Chunks Time-bounded partitions of a hypertable; syncs read and write through the parent hypertable and never address chunks directly. | Bank Accounts is specific to Bill and Chunks to TimescaleDB — 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. | Continuous Aggregates Incrementally maintained rollups that serve as pre-aggregated read sources for downstream systems. | Vendor Credits and Credit Memos is specific to Bill and Continuous Aggregates to TimescaleDB — 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. | Regular PostgreSQL Tables Relational reference data such as devices, tenants, or accounts synced alongside the series data. | Bills is specific to Bill and Regular PostgreSQL Tables to TimescaleDB — 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. | Views Standard SQL views used to shape or filter data for consumers. | Vendors is specific to Bill and Views to TimescaleDB — 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. | Schemas Postgres namespaces used to separate synced datasets by team or environment. | Invoices is specific to Bill and Schemas to TimescaleDB — 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. | Hypertables Time-partitioned tables that hold the main time-series data; the primary read and write target in syncs. | Customers is specific to Bill and Hypertables to TimescaleDB — each maps to any object or custom field on the other side. |
How changes propagate between Bill and TimescaleDB
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 TimescaleDB 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 TimescaleDB as a row-level write, with types converted between the two schemas.
TimescaleDB Bill Sub-second propagation
DetectionChanges in TimescaleDB are captured at the source via change data capture — no polling loop against its API. Log-based capture via PostgreSQL logical decoding where the deployment allows it — hypertable changes surface on the underlying chunk tables and must.
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.
- TimescaleDB: No API rate limits; throughput is bounded by database resources and connection limits.

FAQ
Bill and TimescaleDB integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Bill and TimescaleDB: authenticate both systems, choose the objects to sync (such as Bill's Bank Accounts and Vendor Credits and Credit Memos), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
On the Bill side: Invoices, Customers, Payments, Chart of Accounts, plus custom fields where Bill exposes them. On the TimescaleDB side: Views, Schemas, Hypertables, Chunks. Stacksync auto-detects both schemas and converts types between the two systems.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Bill and TimescaleDB: Internal tools without API plumbing; Write back safely; React to financial events. Build dashboards and back-office tools directly on TimescaleDB; Stacksync handles the API calls, rate limits, and retries against Bill.

Bill: REST/JSON (BILL v3 Connect API). Authentication: Session-based: POST /v3/login with username, password, organizationId, and a developer key (devKey) returns a sessionId that is passed with the devKey as headers on every subsequent call; OAuth is available for partner/embedded apps. TimescaleDB: SQL wire protocol (PostgreSQL). Authentication: Database credentials. Stacksync manages authentication, retries, and rate limits on both sides.
-
Bill: BILL exposes separate AP and AR object sets plus a distinct Spend & Expense API that uses its own token and a lower 60-calls-per-minute limit. TimescaleDB: Native compression converts older chunks to a columnar layout while keeping them queryable with the same SQL. Stacksync's field mapping accounts for these differences between Bill and TimescaleDB without custom code.
