Commerce QuickBooks Integration

Commerce QuickBooks Integration connects Drupal Commerce with QuickBooks Online.

It automatically creates a QuickBooks invoice when a Drupal Commerce order becomes fully paid.

Features

* Connects Drupal with QuickBooks Online using OAuth 2.0.
* Automatically creates a QuickBooks invoice when a Drupal Commerce order becomes fully paid.
* Reuses an existing QuickBooks customer by email, or creates a new customer if one doesn't already exist.
* Builds the QuickBooks invoice from the paid Commerce order's details (line items, quantities, prices, totals).
* Processes synchronization asynchronously through Drupal's Queue API, so checkout performance isn't affected.

Post-Installation

After enabling the module:

1. Go to the Commerce QuickBooks configuration page at /admin/config/services/commerce-qb.
2. Enter the QuickBooks environment, Client ID, Client Secret, OAuth redirect information, and Default QuickBooks Item ID.
3. Authorize the Drupal site with QuickBooks Online.
4. Go to /admin/config/services/commerce-qb/test to use the connection test and verify the QuickBooks API connection.
5. Ensure Drupal cron is configured so the `commerce_qb_sync` queue is processed automatically.

Once configured, fully paid Commerce orders are automatically queued for QuickBooks synchronization.

Additional Requirements

This module requires:

* Drupal Commerce.
* Drupal Commerce Order.
* Drupal Commerce Payment.
* A QuickBooks Online account.
