Why teams connect AWS Aurora MySQL and Bill

Work with Bill's financial data straight from AWS Aurora MySQL: 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 Stored procedures and triggers, Databases (schemas), Tables, Rows in AWS Aurora MySQL and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against AWS Aurora MySQL, 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 a production Aurora cluster with an analytics database while filtering out sensitive columns.
  • 04 Let operations teams edit records in a spreadsheet-style tool with changes written back to Aurora safely.

Common sync patterns

React to financial events

Changes in Bill appear in AWS Aurora MySQL 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 AWS Aurora MySQL 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 AWS Aurora MySQL; Stacksync handles the API calls, rate limits, and retries against Bill.

What you can sync between AWS Aurora MySQL and Bill

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.

AWS Aurora MySQL objects Bill objects How this pairing syncs
Columns MySQL data types are mapped to the paired system's field types during schema setup. 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. Columns is specific to AWS Aurora MySQL and Vendors to Bill — each maps to any object or custom field on the other side.
Primary keys and indexes Used to match rows across systems and keep incremental syncs efficient. Invoices Accounts-receivable invoices sent to customers; created and read via /v3/invoices to keep billing status aligned with the ERP or CRM. Primary keys and indexes is specific to AWS Aurora MySQL and Invoices to Bill — each maps to any object or custom field on the other side.
Views Can serve as read-only sync sources for derived or filtered datasets. Customers AR customer master records; mapped to customer/account records in a CRM or ERP so finance and sales share one view. Views is specific to AWS Aurora MySQL and Customers to Bill — each maps to any object or custom field on the other side.
Foreign keys Express relationships that syncs preserve when mapping to related objects elsewhere. Payments Outgoing vendor payments and received customer payments; read for reconciliation and created to schedule bill pay. Foreign keys is specific to AWS Aurora MySQL and Payments to Bill — each maps to any object or custom field on the other side.
Stored procedures and triggers Existing database logic keeps firing on rows written by a sync. Chart of Accounts GL accounts used to code bills and invoices; typically mastered in the accounting system and written into BILL for consistent coding. Stored procedures and triggers is specific to AWS Aurora MySQL and Chart of Accounts to Bill — each maps to any object or custom field on the other side.
Databases (schemas) Logical namespaces that scope which tables a sync connection can see. Bank Accounts Funding and deposit accounts; read to reconcile payments and posted transactions against the ledger. Databases (schemas) is specific to AWS Aurora MySQL and Bank Accounts to Bill — each maps to any object or custom field on the other side.

How changes propagate between AWS Aurora MySQL and Bill

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.

AWS Aurora MySQL Bill Sub-second propagation

DetectionChanges in AWS Aurora MySQL are captured at the source via change data capture — no polling loop against its API. Log-based CDC via the MySQL binary log (binlog), with polling on timestamp columns as a fallback.

DeliveryEach detected change is written to Bill through its API, with automatic retries and rate-limit backoff.

Bill AWS Aurora MySQL 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 AWS Aurora MySQL as a row-level write, with types converted between the two schemas.

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.
