Why teams connect Bill and Supabase
Work with Bill's financial data straight from Supabase: 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 Vendors, Invoices, Customers, Payments from Bill into JSONB Columns, Database Functions, Storage Object Metadata, Tables in Supabase and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Supabase, 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 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 Push product events captured in Supabase Postgres to marketing tools for lifecycle campaigns
- 04 Consolidate Supabase project data into a warehouse for analytics while keeping the app database as the system of record
Common sync patterns
Write back safely
Updates written to the synced tables in Supabase propagate into Bill, so automations can create or correct finance records without custom integration code.
React to financial events
Changes in Bill appear in Supabase 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 Supabase as regular tables or collections your team can join, index, and query.
What you can sync between Bill and Supabase
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 | Supabase objects | How this pairing syncs | |
|---|---|---|---|
| Chart of Accounts GL accounts used to code bills and invoices; typically mastered in the accounting system and written into BILL for consistent coding. | Database Functions Postgres functions that can transform or validate synced rows. | Chart of Accounts is specific to Bill and Database Functions to Supabase — each maps to any object or custom field on the other side. | |
| Bank Accounts Funding and deposit accounts; read to reconcile payments and posted transactions against the ledger. | Storage Object Metadata File metadata rows that can be joined to synced application data. | Bank Accounts is specific to Bill and Storage Object Metadata to Supabase — 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. | Tables Standard Postgres tables; the primary two-way sync target. | Vendor Credits and Credit Memos is specific to Bill and Tables to Supabase — 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. | Views Read-side projections exposed to outbound syncs. | Bills is specific to Bill and Views to Supabase — 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. | Schemas Namespaces (public and custom) that scope sync access. | Vendors is specific to Bill and Schemas to Supabase — 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. | auth.users Managed authentication users, often mirrored into CRM or support systems. | Invoices is specific to Bill and auth.users to Supabase — each maps to any object or custom field on the other side. |
How changes propagate between Bill and Supabase
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 Supabase 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 Supabase as a row-level write, with types converted between the two schemas.
Supabase Bill Sub-second propagation
DetectionSupabase pushes changes as they happen — webhook events backed by change data capture. Log-based CDC via Postgres logical replication, the same WAL feed that powers Supabase Realtime.
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.
- Supabase: SQL access is bounded by connection limits (pooled connections are provided); the REST layer is subject to the platform's limits.

FAQ
Bill and Supabase integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Bill and Supabase: authenticate both systems, choose the objects to sync (such as Bill's Chart of Accounts and Bank Accounts), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Common patterns for Bill and Supabase: Write back safely; React to financial events; Query finance data like any other data. Updates written to the synced tables in Supabase propagate into Bill, so automations can create or correct finance records without custom integration code.

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. Supabase: Direct PostgreSQL wire protocol connection, plus an auto-generated REST API (PostgREST). Authentication: Database credentials (connection string) for SQL access; API keys (anon / service role) for the REST layer. 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. Supabase: PostgREST auto-generates a REST endpoint per table, with Row Level Security policies gating access at the row level. Stacksync's field mapping accounts for these differences between Bill and Supabase 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 Supabase records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Bill and Supabase connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Bill–Supabase integration in-house.
