Why teams connect Bill and Scaleway Postgres
Work with Bill's financial data straight from Scaleway Postgres: 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 Sequences, Columns, Tables, Views in Scaleway Postgres and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Scaleway Postgres, 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 production tables from Scaleway Postgres into a CRM so sales and support see live product usage on customer records
- 04 Run a two-way sync between Scaleway Postgres and SaaS tools so edits made in either system converge on the same rows
Common sync patterns
React to financial events
Changes in Bill appear in Scaleway Postgres as row changes, so you can trigger downstream logic with the database tooling you already use.
Query finance data like any other data
Customers, invoices, and payments from Bill live in Scaleway Postgres as regular tables or collections your team can join, index, and query.
Internal tools without API plumbing
Build dashboards and back-office tools directly on Scaleway Postgres; Stacksync handles the API calls, rate limits, and retries against Bill.
What you can sync between Bill and Scaleway Postgres
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 | Scaleway Postgres 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. | Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. | Vendor Credits and Credit Memos is specific to Bill and Columns to Scaleway Postgres — 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 Primary sync unit; each table maps to an object or table on the other side of the sync. | Bills is specific to Bill and Tables to Scaleway Postgres — 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 Read-only sources for shaping data before it leaves the database. | Vendors is specific to Bill and Views to Scaleway Postgres — 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 Precomputed result sets that can be read on a schedule for downstream syncs. | Invoices is specific to Bill and Materialized views to Scaleway Postgres — 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. | Schemas Namespace tables so multiple applications or environments can be synced selectively. | Customers is specific to Bill and Schemas to Scaleway Postgres — 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. | Sequences Generate primary keys; sync tooling must respect them when writing rows. | Payments is specific to Bill and Sequences to Scaleway Postgres — each maps to any object or custom field on the other side. |
How changes propagate between Bill and Scaleway Postgres
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 Scaleway Postgres 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 Scaleway Postgres as a row-level write, with types converted between the two schemas.
Scaleway Postgres Bill Sub-second propagation
DetectionChanges in Scaleway Postgres are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication where the managed instance permits it.
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.
- Scaleway Postgres: Throughput is bounded by instance size and connection limits rather than API quotas.

FAQ
Bill and Scaleway Postgres integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Bill and Scaleway Postgres: 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.
-
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 Scaleway Postgres records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Bill and Scaleway Postgres connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Bill–Scaleway Postgres integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Bill and Scaleway Postgres. 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 Scaleway Postgres: Log-based CDC via PostgreSQL logical replication where the managed instance permits it; otherwise timestamp or query-based polling. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
