A plugin for Redmine that integrates with QuickBooks Online (QBO) to automatically create Time Activity entries from billable hours logged on Issues.

When an Issue associated with a Customer is closed, the plugin generates corresponding Time Activities in QuickBooks based on the Redmine Time Entries recorded for that Issue.

Disclaimer

The core functionality is implemented, but the project is under active development.

The master branch may contain unstable changes.
For production deployments, use a tagged release.

Compatibility

Plugin Version	Redmine Version

Features

Issue Billing Integration

Assign a QuickBooks Customer to a Redmine Issue.
Optionally associate a QuickBooks Estimate with the Issue.
Automatically associates a QuickBooks Invoice with the Issue.

Automatic Time Activity Creation

When an Issue with an assigned Customer is closed:

A Time Activity is created in QuickBooks for each relevant Redmine Time Entry.
Time Entries are grouped by Activity name.
Activity names are used to dynamically match Items in QuickBooks.
If no matching Item exists, the activity is skipped.
Labor rates are determined by the associated QuickBooks Item.

Employee Mapping

Redmine Users can be mapped to QuickBooks Employees through the User Administration page.

This ensures Time Activities are recorded under the correct employee in QuickBooks.

Customer Management

The plugin provides basic Customer management:

Create Customers directly from Redmine
Search Customers by name or phone number
View and edit Customer information

Customers are synchronized with QuickBooks.

Webhook Support

The plugin listens for QuickBooks webhook events.

Supported automation:

Invoice Linking

Invoices containing an Issue reference (e.g. #123) automatically attach to the corresponding Issue.

Custom Field Synchronization

Invoice custom fields can be mapped to Issue custom fields.

Example use case:

Mileage In/Out recorded in Redmine
Automatically synchronized to the QuickBooks invoice.

Customer Synchronization

Customer records are automatically updated in the local database when changes occur in QuickBooks.

Plugin Hooks

The plugin exposes several hooks for extending functionality through companion plugins.

Example:

redmine_qbo_vehicles
Adds support for tracking customer vehicles associated with Issues.

Available hooks:

Type	Hook
View Hook	:pdf_left, { issue: issue }
View Hook	:pdf_right, { issue: issue }
Hook	process_invoice_custom_fields, { issue: issue, invoice: invoice }
View Hook	:show_customer_view_right, { customer: customer }

Prerequisites

Before installing the plugin:

Create a QuickBooks developer account:

https://developer.intuit.com/

Create an Intuit application to obtain:

Client ID
Client Secret

Configure the QuickBooks webhook endpoint:

https://redmine.yourdomain.com/qbo/webhook

Installation

1. Clone the Plugin

Install the plugin into your Redmine plugins directory.

cd /path/to/redmine/plugins
git clone https://github.com/rickbarrette/redmine_qbo.git
cd redmine_qbo
git checkout

Use a tagged release for stability.

2. Install Dependencies

bundle install

Required for Redmine 6 / Rails 7 compatibility.

3. Run Database Migrations

bundle exec rake redmine:plugins:migrate RAILS_ENV=production

4. Restart Redmine

Restart your Redmine server so the plugin and hooks are loaded.

Configuration

Navigate to:

Administration → Plugins → Configure

Enter your QuickBooks Client ID and Client Secret.
Save the configuration.
Click Authenticate to complete the OAuth connection with QuickBooks Online.

Once authentication succeeds, the plugin performs an initial synchronization.

User Mapping

Each Redmine user must be mapped to a QuickBooks Employee.

Navigate to:

Administration → Users

Then assign the corresponding QuickBooks Employee to each user.

Usage

To enable automatic billing:

Assign a Customer to an Issue.
Log billable time using Redmine Time Entries.
Close the Issue.

When the Issue is closed, the plugin automatically generates the corresponding Time Activity entries in QuickBooks Online.

After the initial synchronization, the plugin receives updates through Intuit webhooks.

Troubleshooting

Time Activities Not Created

Verify that:

The Issue has a Customer assigned
Time Entries exist for the Issue
Activity names match QuickBooks Item names

Webhooks Not Triggering

Ensure the QuickBooks webhook endpoint is reachable:

https://redmine.yourdomain.com/qbo/webhook

Also verify webhook configuration in the Intuit developer dashboard.
