Why teams connect Bill and SingleStore

Work with Bill's financial data straight from SingleStore: 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 Payments, Chart of Accounts, Bank Accounts, Vendor Credits and Credit Memos from Bill into Stored Procedures, Indexes and Shard Keys, Databases, Tables (rowstore and columnstore) in SingleStore and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against SingleStore, 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 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 Feed synced operational data into applications that need low-latency responses over fresh data.
  • 04 Mirror CRM and SaaS objects into SingleStore tables to serve low-latency operational dashboards.

Common sync patterns

Query finance data like any other data

Customers, invoices, and payments from Bill live in SingleStore 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 SingleStore; Stacksync handles the API calls, rate limits, and retries against Bill.

Write back safely

Updates written to the synced tables in SingleStore propagate into Bill, so automations can create or correct finance records without custom integration code.

What you can sync between Bill and SingleStore

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 SingleStore objects How this pairing syncs
Bank Accounts Funding and deposit accounts; read to reconcile payments and posted transactions against the ledger. Stored Procedures Existing logic sometimes invoked on write paths. Bank Accounts is specific to Bill and Stored Procedures to SingleStore — 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. Indexes and Shard Keys Determine data distribution and lookup speed for sync match keys. Vendor Credits and Credit Memos is specific to Bill and Indexes and Shard Keys to SingleStore — 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. Databases The connection target containing the tables a sync addresses. Bills is specific to Bill and Databases to SingleStore — 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. Tables (rowstore and columnstore) Primary read/write target; storage type affects whether a table suits point lookups or scans. Vendors is specific to Bill and Tables (rowstore and columnstore) to SingleStore — 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. Views Read-only projections used as curated sync sources. Invoices is specific to Bill and Views to SingleStore — 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. Reference Tables Small tables replicated to every node, often used for dimension data in syncs. Customers is specific to Bill and Reference Tables to SingleStore — each maps to any object or custom field on the other side.

How changes propagate between Bill and SingleStore

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 SingleStore 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 SingleStore as a row-level write, with types converted between the two schemas.

SingleStore Bill Interval-based propagation

DetectionStacksync polls SingleStore for changes on an incremental schedule, reading only records changed since the previous pass. Polling on timestamp or watermark columns.

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.
  • SingleStore: No API rate limits; throughput is bounded by workspace or cluster size.
