-# Redmine Quickbooks Online
+# Redmine QuickBooks Online Plugin
 
-A plugin for Redmine to connect to Quickbooks Online
+A plugin for **Redmine** that integrates with **QuickBooks Online (QBO)** to automatically create **Time Activity entries** from billable hours logged on Issues.
 
-The goal of this project is to allow Redmine to connect with Quickbooks Online to create Time Activity Entries for billable hours loged when an Issue is closed.
+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
+---
 
-Note: Although the core functionality is complete, this project is still under development & the master branch may be unstable. Tags should be stable and are recommended
+# Disclaimer
 
-Use tags for the following Redmine Versions
+The core functionality is implemented, but the project is **under active development**.
-* Version 2.0.0+ for Redmine 5+
-* Version 1.0.0+ for Redmine 4+ 
-* Version 0.8.1 for Redine 3
 
-#### Features
+The `master` branch may contain unstable changes.  
-* Issues can be assigned to a Customer via drop down in the edit Issue form
+For production deployments, **use a tagged release**.
-  - Once a customer is attached to an Issue, you can attach an Estimate to the issue via a drop down menu
-* Employee is assigned to a user via a drop down in the user admistration page.
-* IF an Issue has been assined a Customer when an Issue is closed the following will happen:
-  - A new Time Activity will be billed agaist the Customer assinged to the issue for each Redmine Time Entery. 
-    + Time Entries will be totalled up by Activity name. This will allow billing for diffrent activities without having to create seperate Issues.
-    + The Time Activity names are used to dynamically lookup Items in Quickbooks.
-    + IF there isn't any Items that match the Activity name it will be skipped, and will not be billed to the Customer 
-  - Labor Rates are set by corresponding the Item in Quickbooks
-* Customers Can be created via the New Customer Page
-  - Customers can be searched by name or phone number
-  - Basic information for the Customer can be viewed/edit via the Customer page
-* Webhook Support
-  - Invoices are automaticly attached to an Issue if a line item has a hashtag number in a Line Item
-    + Invoice Custom Fields are matched Issue Custom Fileds and are automaticly updated in Quickbooks. For example, this is usefull for extracting the Mileage In / Out from the Issue and updating the Invoice with the information.
-  - Customers are automaticly updated in local database
 
-## Prerequisites
+---
 
-* Sign up to become a developer for Intuit https://developer.intuit.com/
+# Compatibility
-* Create your own aplication to obtain your API keys
-* Set up webhook service to https://redmine.yourdomain.com/qbo/webhook
 
-## The Install
+| Plugin Version | Redmine Version |
+| :--- | :--- |
+| Version 2026.1.0+ | Redmine 6.1 |
+| Version 2.0.0+ | Redmine 5 |
+| Version 1.0.0+ | Redmine 4 |
+| Version 0.8.1 | Redmine 3 |
 
-1. To install, clone this repo into your plugin folder & checkout a tagged version
+---
 
-  `git clone git@github.com:rickbarrette/redmine_qbo.git` 
+# Features
-  
-  then
-  
-  `git checkout <tag>`
-  
-2. Migrate your database
 
-  `rake redmine:plugins:migrate RAILS_ENV=production`
+## Issue Billing Integration
-  
-3. Navigate to the plugin configuration page and suppy your own OAuth key & secret. 
 
-4. After saving your key & secret, you need to click on the Authenticate link on the plugin configuration page to authenticate with QBO.
+*   Assign a **QuickBooks Customer** to a Redmine Issue.
+    
+*   Optionally associate a **QuickBooks Estimate** with the Issue.
 
-5. Assign an Employee to each of your users via the User Administration Page
+*   Automatically associates a **QuickBooks Invoice** with the Issue.
+    
 
-## Usage
+---
 
-  To enable automatic Time Activity entries for an Issue , you need only to assign a Customer to an Issue via drop downs in the issue creation/update form.
+## Automatic Time Activity Creation
 
-Note: After the inital synchronization, this plugin will recieve push notifications via Intuit's webhook service.
+When an Issue with an assigned Customer is closed:
 
-## TODO
+*   A **Time Activity** is created in QuickBooks for each relevant Redmine Time Entry.
-  * Add Setting for Sandbox Mode
+    
-  * Seperate Vehicles into a seperate plugin (I use redmine for my automotive shop management 😉)
+*   Time Entries are **grouped by Activity name**.
-  * MORE Stuff as I make it up...
+    
+*   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|Note
+|--|--|--|
+View Hook|:pdf_left, { issue: issue }  | Used to add text to left side of PDF
+View Hook|:pdf_right, { issue: issue }  | Used to add text to right side of PDF
+Hook|process_invoice_custom_fields, { issue: issue, invoice: invoice }  | Used to process invoice custom fields
+View Hook|:show_customer_view_right, { customer: customer } | Used to show partials on right side of customer view
+Hook| :qbo_additional_entities | Used to add additional entites to be processed by the WebhookProcessJob
+Hook| :qbo_full_sync | Used to add a Class to be called by the QboSyncDispatcher
+
+---
+
+# Prerequisites
+
+Before installing the plugin:
+
+1.  Create a QuickBooks developer account:
+    
+
+[https://developer.intuit.com/](https://developer.intuit.com/)
+
+2.  Create an **Intuit application** to obtain:
+    
+
+*   Client ID
+    
+*   Client Secret
+    
+
+3.  Configure the QuickBooks webhook endpoint:
+    
+
+https://redmine.yourdomain.com/qbo/webhook
+
+---
+
+# Installation
+
+## 1\. Clone the Plugin
+
+Install the plugin into your Redmine plugins directory.
+
+```bash
+cd /path/to/redmine/plugins  
+git clone https://github.com/rickbarrette/redmine_qbo.git  
+cd redmine_qbo  
+git checkout <tag>
+```
+
+Use a **tagged release** for stability.
+
+---
+
+## 2\. Install Dependencies
+
+```bash
+bundle install
+```
+
+Required for **Redmine 6 / Rails 7 compatibility**.
+
+---
+
+## 3\. Run Database Migrations
+
+```bash
+bundle exec rake redmine:plugins:migrate RAILS_ENV=production
+```
+
+---
+
+## 4\. Restart Redmine
+
+Restart your Redmine server so the plugin and hooks are loaded.
+
+---
+
+# Configuration
+
+1.  Navigate to:
+    
+
+Administration → Plugins → Configure
+
+2.  Enter your **QuickBooks Client ID and Client Secret**.
+    
+3.  Save the configuration.
+    
+4.  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:
+
+1.  Assign a **Customer** to an Issue.
+    
+2.  Log billable time using **Redmine Time Entries**.
+    
+3.  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.
