# Taiwanese invoices and eGUI information

When the selling entity for a shopper transaction is Digital River Taiwan, you need to collect specific information from customers and use it to populate a Government Uniform Invoice (GUI or eGUI). You can do this by capturing information collected in a specific custom invoice related to that transaction. The Taiwanese government uses this invoice to collect tax revenue and minimize tax avoidance. 

The Digital River Extension automatically displays the required **Invoice** fields during checkout where appropriate (for example, for local online sales to shoppers in Taiwan). During checkout, the type of invoicing information you need to collect depends on whether the transaction is for an individual or a business.

## Collect invoice information from an individual's transaction

To collect the invoice information from an individual's purchase, you must:

1. Choose one of the following options:
   1. Select a carrier from the **E-invoice Carrier** dropdown list. This is the carrier you associate with your GUI number (your personal identity), assuming that the GUI is tied to your personal identity. Complete the fields.\

   2. Select a charity from the **E-invoice Carrier list** and donate your GUI number to a charity. Complete the fields.\

3. Click **Submit**.

## Collect invoice information from a business transaction

To collect the needed invoice information from a business purchase, you must:

1. On the shipping or billing address page, select the **This is a business purchase** check box.\

**Note:** In both of the described order flows, the payment instrument input fields do not appear until you have added your Invoice or Tax ID information and have clicked the appropriate button to **Submit** or **Apply**.
{% endhint %}

{% hint style="info" %}
**Note:** If your order total changes while checking out (for example, you apply a coupon or a store credit to your purchase), you need to resubmit your **Invoice** or **Tax ID** information. Your information is persisted, but you need to press the **Submit** or **Apply** button again. A message is provided in the checkout modal to remind you. The following shows an example of this message:\
