-#redmine_qbo
+# Redmine QuickBooks Online
 
-##About
+A plugin for Redmine to connect to QuickBooks Online.
 
-This is a simple plugin for Redmine to connect to Quickbooks Online
+The goal of this project is to allow Redmine to connect with QuickBooks Online to create Time Activity Entries for billable hours logged when an Issue is closed.
 
-The goal of this project is to allow redmine to connect with Quickbooks Online to create time activity entries for completed work when an issue is closed.
+## Disclaimer
 
-####How it works
-* A QBO customer and service item can now be assigned to an issue. 
-* When a issue is closed, a new QBO Time Activity is created
-  - The total time for the Time Activity will be total spent time.
-  - The rate will be the set be the service item
+**Note:** Although the core functionality is complete, this project is still under development and the master branch may be unstable. Tags should be stable and are recommended.
 
-*Warning: * This is under heavy development
+## Compatibility
 
-##Prerequisites
+| 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 |
 
-Sign up to become a developer for Intuit https://developer.intuit.com/
+## Features
 
-##The Install
+* **Customer Assignment:** Issues can be assigned to a Customer via a dropdown in the edit Issue form.
+    * Once a customer is attached to an Issue, you can attach an Estimate to the issue via a dropdown menu.
+* **Employee Mapping:** An Employee is assigned to a Redmine User via a dropdown in the User Administration page.
+* **Automatic Billing:** If an Issue has been assigned a Customer, the following happens when the Issue is closed:
+    * A new Time Activity will be billed against the Customer assigned to the issue for each Redmine Time Entry.
+    * Time Entries will be totalled up by Activity name. This allows billing for different activities without having to create separate Issues.
+    * The Time Activity names are used to dynamically lookup Items in QuickBooks.
+    * If there are no Items that match the Activity name, it will be skipped and will not be billed to the Customer.
+    * Labor Rates are set by the corresponding Item in QuickBooks.
+* **Customer Management:** 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/edited via the Customer page.
+* **Webhook Support:**
+    * **Invoices:** Automatically attached to an Issue if a line item contains a hashtag number (e.g., `#123`).
+    * **Custom Fields:** Invoice Custom Fields are matched to Issue Custom Fields and are automatically updated in QuickBooks. (Useful for extracting Mileage In/Out from the Issue to update the Invoice).
+    * **Sync:** Customers are automatically updated in the local database.
+* **Plugin View Hooks** Allows intergration of other features supported by companion plugins, for example [redmine_qbo_vehicles](https://github.com/rickbarrette/redmine_qbo_vehicles) adds customer vehicle interation
