The DOKU Checkout Page now begins with a dedicated Customer Information step, collecting essential details before customers proceed to payment.

Fields collected:

* Name
* Email Address
* Phone Number
* Postal Code – City – District – Province (dropdown selection)
* Address (free text)

This update ensures:

* Complete and accurate customer data captured at checkout
* Fewer failed deliveries due to missing or incomplete address information
* No need for separate forms or CRM flows to collect customer data

### How the is Customer Data Collection is Working

#### 🔄 **Before This Update**&#x20;

Today, customers proceed directly to payment selection without a standardized way to provide their personal and shipping information at checkout. While functional, this often results in incomplete or inconsistent customer data, requiring merchants to follow up manually after payment to confirm delivery details.

Steps:

1. Customer reaches Checkout Page
2. Customer selects payment method directly
3. Customer completes payment
4. Merchant manually follows up to collect missing customer or shipping information (if needed)

#### 🆕 **After This Update**

With Customer Data Collection, the checkout now follows a structured 2-step flow, ensuring every transaction comes with complete and verified customer information from the start.

Steps:

1. Customer fills in name, email, phone number, location, and address. The 'Next' button stays disabled until all required fields are complete.
2. Customer selects a payment method. Submitted customer data appears in the Order Summary panel under "Customer Information," with an option to edit.
3. If the customer clicks 'Edit' in Step 2, a confirmation modal warns that unsaved payment data will be lost, with options to 'Cancel' or 'Edit Customer'.
4. Customer completes payment.
