Two-way sync
Changes in DuckDB or QuickBooks instantly reflect in both systems. No stale data, no manual imports.
Keep DuckDB and QuickBooks in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 Journal entries, Estimates, Purchase orders, Credit memos from QuickBooks into Views, External files (Parquet/CSV/JSON), Attached databases, Database files in DuckDB and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against DuckDB, and rows your code writes or updates flow back into QuickBooks with validation, so the finance system stays the system of record.
Build dashboards and back-office tools directly on DuckDB; Stacksync handles the API calls, rate limits, and retries against QuickBooks.
Updates written to the synced tables in DuckDB propagate into QuickBooks, so automations can create or correct finance records without custom integration code.
Changes in QuickBooks appear in DuckDB as row changes, so you can trigger downstream logic with the database tooling you already use.
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.
| DuckDB objects | QuickBooks objects | |
|---|---|---|
| Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. | Vendors Supplier records aligned with purchasing and spend tools | |
| Schemas Namespaces within a database used to organize tables in sync outputs. | Items Products and services referenced on invoice and bill lines | |
| Tables Columnar tables created via SQL; the destination for materialized sync data. | Accounts The chart of accounts, mirrored so external postings map to the right ledger lines | |
| Views SQL views used to shape or filter data for downstream consumers. | Journal entries Manual postings exported for consolidated financial reporting | |
| External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. | Estimates Quotes that convert to invoices, synced with CRM quoting flows | |
| Attached databases Additional database files or external systems attached into one session for cross-source queries. | Purchase orders Procurement documents synced with inventory and ordering systems |
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every DuckDB–QuickBooks connection.
Changes in DuckDB or QuickBooks instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever DuckDB or QuickBooks data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single DuckDB or QuickBooks record.
Track your DuckDB ⇄ QuickBooks sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between DuckDB and QuickBooks.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate DuckDB and QuickBooks with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the DuckDB and QuickBooks objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between DuckDB and QuickBooks: authenticate both systems, choose the objects to sync (such as DuckDB's Database files and Schemas), map fields visually, and changes propagate both ways in milliseconds — no code required.
DuckDB: In-process SQL engine via client libraries (Python, Node.js, JDBC, CLI); no server or network API by default. Authentication: None built in; access control is file-system level (MotherDuck adds token auth for its hosted service). QuickBooks: REST API (QuickBooks Online). Authentication: OAuth 2.0. Stacksync manages authentication, retries, and rate limits on both sides.
QuickBooks: The QuickBooks Online API includes a Change Data Capture operation that returns entities modified since a given timestamp, which incremental syncs use directly. DuckDB: DuckDB runs in-process like SQLite; there is no server, so integrations embed the engine or operate on the single-file databases it produces. Stacksync's field mapping accounts for these differences between DuckDB and QuickBooks 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 DuckDB and QuickBooks records are not retained after a sync operation.
Stacksync pricing is usage-based and starts at $1,000/month, including the managed DuckDB and QuickBooks connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom DuckDB–QuickBooks integration in-house.
Yes — Stacksync ships production-grade connectors for both DuckDB and QuickBooks. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
