The best QuickBooks Desktop & Enterprise API on the planet
Real-time access to every QuickBooks Desktop object via Python, Node.js/TypeScript, and REST.
In just a few lines, get real-time access to 256 fully-typed endpoints for QuickBooks Desktop and Enterprise.
Even if you know nothing about QuickBooks, integrating with Conductor will take less dev time and be more robust and flexible than any other approach, all by leveraging our autocomplete, type-safety, inline docs, and multi-layered error handling.
Conductor completely abstracts away the fragility and quirks of QuickBooks Desktop, the Web Connector, qbXML, SOAP, and so much more.

Create, manage, monitor, and debug your end-user connections from our lightning-fast dashboard. Set up new end-users, keep watch over live connections, and track down problems as soon as they come up, all from one place.
Conductor’s MCP server connects QuickBooks Desktop to the AI tools you already use, even though it runs on-premises:
Your AI tools can read, create, and update any record supported by the Conductor API.
Works with any MCP-compatible client, including Claude, ChatGPT, and Cursor.
Every request goes through the same authenticated connection as your app.

Which invoices are 30+ days overdue?
Thought for 4s
I’ll use Conductor to pull open invoices from QuickBooks Desktop, keep the ones 30+ days overdue, and add customer names.
Conductor found 2 invoices 30+ days overdue, totaling $7,970:
Hartwell Construction
$4,820.00
Bluepine Landscaping
$3,150.00
Add “Follow up Oct 20” to both memos
Thought for 2s
Conductor can write the memo field on each invoice directly.
Updating invoice memos with Conductor
Done. Conductor updated both memos in QuickBooks Desktop.
Ask a follow-up…
Conductor is designed to be entirely self-service for your end-users to require zero customer support from you:
Straightforward, interactive auth flow for end-users to connect their QuickBooks Desktop to your app.
A growing library of guides for your end-users to resolve any Windows or QuickBooks issue they encounter.
Every error has a user-friendly message with resolution instructions and a link to a related help guide.
Normally, QuickBooks Desktop's errors are cryptic and unhelpful and can arise from several sources each with a different format. Sometimes, their errors do not even describe what went wrong when they could!
Conductor unifies QuickBook's errors into a single, consistent error format and augments each with our own user-friendly error message that describes how to resolve the issue.
