This plugin allows billable line items to be attached to a Redmine issue. When the issue is closed, the plugin automatically generates a QuickBooks Online estimate containing those line items.

Requirements

Redmine: 6.1+
Ruby: 3.2+
Parent Plugin: Redmine QuickBooks Online (must be installed and configured)

Compatibility

Plugin Version	Redmine Version	Ruby Version
2026.3.2+	6.1.x	3.2+

Features

Billable Line Items: Attach billable products or services directly to any Redmine issue.
Automated Estimate Creation: Automatically generates a QuickBooks Online Estimate when an issue is closed, streamlining the billing workflow.

Why Estimates?

Intuit does not currently provide an API for creating Delayed Charges in QuickBooks Online.

Because of this limitation, the plugin generates an Estimate when an issue is closed. This estimate can later be converted into an invoice within QuickBooks.

The alternative approach would be to modify an invoice directly after it is associated with an issue, which introduces additional complexity and potential synchronization issues.

Installation

Clone the plugin

Navigate to your Redmine plugins directory:

cd /path/to/redmine/plugins
git clone git@github.com:rickbarrette/z_redmine_qbo_lineitems.git
cd z_redmine_qbo_lineitems

# Optional: checkout a specific version
git checkout

Install dependencies

bundle install

Migrate your database

bundle exec rake redmine:plugins:migrate RAILS_ENV=production

Restart Redmine

Restart your application server (Puma, Passenger, etc.) to initialize the plugin hooks.

Configuration

This plugin depends on the Redmine QuickBooks Online plugin.

Before using this plugin:

Install and configure the parent plugin.
Ensure your QuickBooks Online company file is connected.
Verify that the products or services referenced in line items exist in QuickBooks.

Usage

Configure: Ensure the parent QuickBooks Online plugin is connected to your company file.
Add Items: On the issue page, use the new Line Items section to add billable products or services.
Generate Estimate: When the work is complete, change the issue status to a state marked as closed in Redmine. The plugin will then trigger the creation of a new estimate in QuickBooks Online.
