+# Purchase Invoice Subtotal with Taxes
+
+## Description
+
+This module adds two optional columns to purchase orders and invoices to display the subtotal both with and without taxes, regardless of the tax configuration in Odoo.
+
+### Problem
+
+By default, Odoo only shows one subtotal column in purchase orders and invoices based on the tax configuration:
+- If taxes are configured as "included in price", it shows the total with taxes
+- If taxes are configured as "excluded from price", it shows the total without taxes
+
+However, in some cases, users need to see **both** values at the same time for comparison or reporting purposes.
+
+### Solution
+
+This module adds two new optional columns:
+- **Subtotal (No Tax)**: Always shows the line subtotal without taxes included
+- **Subtotal (Tax Incl.)**: Always shows the line subtotal with taxes included
+
+These columns are available in:
+- Purchase order lines
+- Invoice lines (customer and vendor invoices)
+
+Both columns are hidden by default (optional="hide") and can be shown by users as needed using the column visibility controls.
+
+## Installation
+
+1. Install the module from the Apps menu
+2. No additional configuration is required
+
+## Usage
+
+After installation:
+1. Go to a purchase order or invoice
+2. In the lines view, click on the column selector (≡ icon)
+3. Enable "Subtotal (No Tax)" and/or "Subtotal (Tax Incl.)" columns
+4. Both values will be displayed regardless of your tax configuration
+
+## Technical Details
+
+The module creates two computed fields on:
+- `purchase.order.line`: `price_subtotal_no_tax` and `price_subtotal_with_tax`
+- `account.move.line`: `price_subtotal_no_tax` and `price_subtotal_with_tax`
+
+These fields are based on the existing `price_subtotal` (without tax) and `price_total` (with tax) fields, ensuring consistency with Odoo's core calculations.
