Interim UX guidelines for user choice billing pilot

Note: Google is sunsetting manual implementation of the interim UX guidelines. Learn more about migration deadlines here. If you are offering user choice billing through alternative billing APIs, you can meet the user experience requirements by integrating with and using the client-side APIs. In this case, you don't need to separately follow the interim user experience guidelines outlined in this topic.

Overview

The user choice billing pilot allows participating developers to test offering an alternative billing option next to Google Play's billing system and is designed to help us explore offering this choice to users. These UX guidelines aim to maintain a consistent user experience and help users make an informed decision.

You are required to display an information screen and a separate billing choice screen if you are participating in the pilot. The information screen only needs to be shown to each user the first time the user initiates a purchase, while the billing choice screen must be shown before every purchase. The user-facing messages and UI specifications for both screens must be implemented according to the following guidelines.

Information for users

The information screen helps users understand the context of the change and gives more information to help them make an informed choice.

When to display

The information screen must be shown to users at the start of their first purchase after you add an alternative billing system. This message does not need to be displayed on subsequent purchases by the same user. Display the information screen immediately after a user has taken explicit action to initiate a purchase.

When to display price

The purchase price must be visible and obvious to users before they are shown either the information screen or the billing choice screen.

How to display

The information screen must be displayed in a modal bottom sheet. A modal bottom sheet is similar to a modal dialog that animates up from the bottom of the screen and stays pinned to the bottom. It is elevated above all UI elements on the underlying screen. The underlying screen is obscured behind a dark scrim to indicate that it will not respond to user interaction.

Refer to Google Material Design for more information on the design and implementation of modal bottom sheets.

User actions

The bottom sheet should be triggered when a user taps on a button or other UI element in your app that initiates a purchase. The user can take three possible actions from the information screen:

Continue

Tapping the “Continue” button dismisses the information screen and launches the billing choice screen.

Learn more

Tapping the “Learn more” button launches a Google Help Center article in a web browser.

Dismiss

If users want to dismiss the bottom sheet and return to the underlying screen, they can dismiss the bottom sheet by:

• Tapping outside of the bottom sheet container
• Tapping the Android system "Back" button

The information screen does not need to be displayed again after it has been dismissed or after the user has tapped “Continue”.

Example: When the user taps to purchase in your app, the button will trigger the information screen.

Design specifications

The information screen is divided into three components: title, message, and buttons. All three components are required and must contain the exact text and UI elements defined in these guidelines. Do not include any additional text or imagery on this screen, but you are free to include additional text and imagery on other screens.

Billing choice screen

The billing choice screen presents users with two checkout options to complete their purchase. To help users make an informed decision, each billing service option also displays their available forms of payment. Once users make their choice, they will continue to complete their purchase through that billing system.

When to display

If the user has already seen the information screen during a previous purchase, the billing choice screen should appear immediately after the user has taken explicit action to initiate a purchase.

How to display

The billing choice screen must be displayed in a modal bottom sheet and follow the same specifications as the information screen.

Equal visual representation

The buttons for the alternative billing system and Google Play’s billing system should be represented in a fair and equal manner. This includes but is not limited to equal button sizes, text size/style, tap targets, and icon sizes. Please do not add any additional text, images, or style changes not defined in these guidelines.

Example: When a user taps to purchase in your app, the button will trigger the billing choice screen, only if the user has already seen the information screen during a previous purchase.

Design specifications

The billing choice screen has four distinct components: title, description, developer button, and the Google Play button. All components must be used, and must contain the exact text and UI elements defined in these guidelines. We ask you not to include any additional text or imagery on this screen, but you are free to include additional text and imagery on other screens owned by you.

Visual assets for Google Play and payment icons are available through the links provided below.

Example: In portrait view, the bottom sheet should span 100% of the total screen width.
