Add 3 Upsell Products To The Website Cart Page
Product Requirements Document

Product Requirements Document: Upsell Products on Cart Page

1. Introduction/Overview

This feature adds three upsell product recommendations to the website's cart page. The goal is to increase average order value by suggesting relevant products to customers before they proceed to checkout.

2. Goals

  • Increase average order value by 5% within one month of launch.
  • Increase conversion rate from cart page to checkout by 2%.
  • Drive more visibility to related product offerings.

3. User Stories

(Due to the limited information, user stories are generic. More specific stories would be added with more user context.)

  • As a customer, I want to see recommended products on the cart page so that I can easily add related items to my order.
  • As a website owner, I want to increase sales by promoting relevant products to customers during the checkout process.

4. Functional Requirements

  1. The system must display three upsell product recommendations on the cart page.
  2. The upsell products must be visually distinct from the items already in the cart.
  3. Each upsell product display must include:
    • Product image
    • Product name
    • Product price
    • An "Add to Cart" button or link.
  4. Clicking the "Add to Cart" button or link for an upsell product must add the product to the cart without navigating away from the cart page (AJAX implementation suggested).
  5. The system should dynamically select upsell products based on the items already in the cart (recommendation engine logic - see Technical Considerations).
  6. If there are fewer than three suitable upsell products based on cart contents, the system must display the available products and not display any empty product slots. For example, if only two relevant upsell products are found, only two upsell products should be displayed.
  7. The system must handle cases where no upsell recommendations can be determined. In such instances, a message communicating this should be displayed to the user (e.g. "No recommendations found, browse our site for more great products!").

5. Non-Goals (Out of Scope)

  • Personalized upsell recommendations based on user browsing history (only cart contents will be used).
  • A/B testing of upsell product selection algorithms in the initial release.
  • Upsell recommendations on any pages other than the cart page.
  • Integration with third party upsell recommendation services.

6. Design Considerations

  • The upsell product display should be placed below the cart contents summary on the cart page.
  • The design should be responsive and adapt to different screen sizes.
  • Follow existing website UI guidelines for fonts, colors, and button styles.

7. Technical Considerations

  • The upsell product recommendation logic should be implemented as a separate module or service. This will facilitate future improvements and A/B testing of recommendation algorithms.
  • Consider using AJAX to add upsell products to the cart without a page refresh.
  • Integrate with the existing product catalog and shopping cart modules.
  • The recommendation engine should handle edge cases such as empty carts, carts with only discounted items, and carts with products that have no associated upsell suggestions.

8. Success Metrics

  • Average Order Value (AOV): Track the percentage change in AOV after launch.
  • Cart Conversion Rate: Monitor the conversion rate from cart page to checkout.
  • Upsell Product Sales: Track the number of upsell products sold as a percentage of total sales.

9. Open Questions

  • What is the specific algorithm or logic for selecting upsell products? (e.g., based on category, tags, frequently bought together)
  • Should the upsell products be filtered based on inventory availability?
  • What error handling should be implemented for adding products to the cart (e.g., out of stock)?
  • What analytics events should be tracked for user interactions with the upsell product recommendations?
