Product Requirements Document: Upsell Cart Feature

1. Introduction/Overview

This document outlines the requirements for implementing an upsell feature within the shopping cart. The goal is to increase the average order value and promote specific products by strategically offering relevant upsells to users during their shopping journey, specifically when adding a product to the cart and proceeding to checkout. This feature will address the need to present targeted product recommendations to users, thereby enhancing their shopping experience and encouraging them to purchase more.

2. Goals

Increase Average Order Value (AOV): Increase the average order value by X% within the first month of launch.
Promote Specific Products: Increase the sales of selected promotional products by Y% within the first two weeks of launch.
Reduced cart abandonment rate: Decrease cart abandonment rate by Z% within the first month of launch.

3. User Stories

As a returning user, I want to see personalized upsell recommendations based on my browsing history, so I can easily find relevant products I might be interested in.
As a new user, I want to see popular or trending products as upsell options when I add an item to my cart, so I can discover new items that might interest me.
As any user, I want to be able to add upsell products to my cart with one click, so I can quickly and easily add them to my order.
As a user in a specific geographic location, I want to see upsell products popular in my region, so I can find relevant items.

4. Functional Requirements

The system must display upsell product recommendations when a user adds a product to the cart.
The system must display upsell product recommendations when the user proceeds to checkout.
The system must personalize upsell offers based on user browsing history.
The system must personalize upsell offers based on user location.
The system must display products that are currently on sale as upsell options.
The system must allow users to add upsell products to their cart with a single click.
The system must limit the number of upsell products displayed to a maximum of three.
The system must clearly display the price and a brief description of each upsell product.
The system must track which upsell products are added to the cart.
The system must have a back-end admin interface to configure the rules for upsell product selection (e.g., products on sale, trending products, location-based products).

5. Non-Goals (Out of Scope)

Cross-selling functionality (recommending products from different categories).
Integration with third-party recommendation engines (at initial launch). This might be considered in future iterations.
A/B testing of different upsell strategies within the initial release.
Complex rule-based upsell logic beyond sale items, browsing history, and geographic location for version 1.0.

6. Design Considerations (Optional)

The upsell products should be displayed in a visually appealing manner, perhaps using a carousel or grid layout. Ensure the design is responsive and works well on both desktop and mobile devices. Follow the existing UI/UX patterns of the e-commerce platform to maintain consistency. See mockups [Link to Mockups].

7. Technical Considerations (Optional)

The upsell feature should integrate with the existing product catalog and shopping cart modules.
Consider using a caching mechanism to improve performance, as the upsell recommendations may require querying the database.
Ensure the upsell logic is easily configurable through the admin interface.
Consider using the existing user profile data for personalization.

8. Success Metrics

Average Order Value (AOV): Track the average order value before and after the implementation of the upsell feature. A successful implementation should result in an increase in AOV.
Upsell Conversion Rate: Measure the percentage of users who add an upsell product to their cart.
Sales of Promotional Products: Track the sales of the specific products being promoted through the upsell feature.
Cart Abandonment Rate: Monitor the cart abandonment rate to see if the upsell feature influences users to complete their purchase.
User Engagement: Track user engagement metrics such as time spent on site and number of pages visited.

9. Open Questions

What is the specific algorithm for determining trending products?
What data sources are available for determining user location?
What is the process for adding new promotional products to the upsell rotation?
