Add a customizable one-click COD checkout form to product pages. Skip cart, skip checkout, more sales.

== Description ==

**COD Express Checkout** adds a streamlined, one-click checkout form directly beneath the product price on WooCommerce single product pages. This form appears **only when Cash on Delivery (COD) is enabled** as a payment method, allowing customers to bypass the traditional cart → checkout flow entirely.

= Perfect for COD-Heavy Markets =

Cash on Delivery dominates in specific regions:

* **Middle East**: 60-80% of e-commerce transactions are COD
* **South Asia** (India, Pakistan, Bangladesh): 50-70% COD preference
* **Southeast Asia**: 40-60% COD usage
* **Latin America**: Growing COD adoption

= Key Features =

* ⚡ **Express Checkout Form** - Displays directly on product page
* 🎯 **COD-Specific** - Only shows when COD payment is enabled
* 📱 **Mobile Optimized** - Responsive design for all devices
* ⚙️ **Fully Configurable** - Toggle fields, customize labels, reorder fields
* 🔄 **Variable Products** - Full support for variable products with variations
* 📝 **Order Notes** - Optional customer notes field
* 🔒 **Secure** - Nonce verification, input sanitization, rate limiting
* 🌐 **Translation Ready** - Full i18n support
* 🎨 **Theme Agnostic** - Works with any WordPress theme
* 🔗 **Developer Friendly** - Extensive hooks and filters
* 📍 **Shortcode Support** - Place the form anywhere on your site

= How It Works =

1. Customer lands on a product page
2. Sees the express checkout form below the price
3. For variable products, selects their preferred variation
4. Fills in name, phone, and address
5. Clicks "Order Now - Pay on Delivery"
6. Order is created instantly via AJAX
7. Customer sees confirmation message

No cart page. No checkout page. Just one form, one click!

= Conversion Benefits =

* **Reduce cart abandonment** by 50%+
* **Capture impulse buyers** at peak buying intent
* **Decrease checkout time** from 3-5 minutes to under 60 seconds
* **Improve mobile conversion rates** with simplified flow

[cod_express_checkout product_id="123"]

**Parameters:**
* `product_id` - (Required if not on product page) The WooCommerce product ID
* `button_text` - (Optional) Override the button text

**Examples:**
[cod_express_checkout product_id="123"]
