## Invoice system

The invoice system gives merchants a complete payment collection workflow. Create invoices with line items, send them by email, and track status from draft to paid — all from the dashboard or API.

## E-commerce payment suite

### Shopify plugin

The Shopify integration lets merchants install an AbabilPay app, connect through OAuth, and present a crypto payment option alongside existing checkout methods.

| Feature         | Detail                                                                   |

| Auto-convert    | Customers can pay with any supported token — merchant receives USDC.     |
| Order sync      | Confirmed payment marks the Shopify order as paid automatically.         |
| Refunds         | Merchant initiates refunds from the AbabilPay dashboard.                 |

### WooCommerce plugin

The WooCommerce plugin is installed as a standard WordPress plugin. It mirrors the Shopify payment flow and automatically synchronizes orders and refunds with your WooCommerce store.
