Why teams connect Bill and Dynamo DB

Work with Bill's financial data straight from Dynamo DB: 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 Bills, Vendors, Invoices, Customers from Bill into Global Tables, Tables, Items, Attributes in Dynamo DB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against Dynamo DB, 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 Stream item changes from DynamoDB application tables into a Postgres or warehouse copy for SQL analytics.
  • 04 Sync customer records between DynamoDB-backed services and a CRM so support and sales see live application state.

Common sync patterns

Internal tools without API plumbing

Build dashboards and back-office tools directly on Dynamo DB; Stacksync handles the API calls, rate limits, and retries against Bill.

Write back safely

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

React to financial events

Changes in Bill appear in Dynamo DB as row changes, so you can trigger downstream logic with the database tooling you already use.

What you can sync between Bill and Dynamo DB

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 Dynamo DB objects How this pairing syncs
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. Global Secondary Indexes Alternate access paths used when sync queries filter on non-key attributes. Bills is specific to Bill and Global Secondary Indexes to Dynamo DB — 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. DynamoDB Streams Ordered item-level change records consumed for incremental sync. Vendors is specific to Bill and DynamoDB Streams to Dynamo DB — 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. Global Tables Multi-region replicas relevant when syncs must read from a specific region. Invoices is specific to Bill and Global Tables to Dynamo DB — 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. Tables The top-level containers a sync targets; each table is addressed independently. Customers is specific to Bill and Tables to Dynamo DB — 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. Items Schemaless records keyed by partition (and optional sort) key, mapped to rows or SaaS objects in syncs. Payments is specific to Bill and Items to Dynamo DB — each maps to any object or custom field on the other side.
Chart of Accounts GL accounts used to code bills and invoices; typically mastered in the accounting system and written into BILL for consistent coding. Attributes Per-item fields, including nested maps and lists, flattened or mapped during sync. Chart of Accounts is specific to Bill and Attributes to Dynamo DB — each maps to any object or custom field on the other side.

How changes propagate between Bill and Dynamo DB

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

Dynamo DB Bill Sub-second propagation

DetectionChanges in Dynamo DB are captured at the source via change data capture — no polling loop against its API. Item-level change streams via DynamoDB Streams or Kinesis Data Streams integration.

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.
  • Dynamo DB: Throughput is governed by the table's provisioned or on-demand capacity mode.
