How Heavenshop Achieved $394K in Revenue Uplift

The Challenge

Navigating a Complex Product Catalog

Heavenshop has built a reputation as a go-to destination for quality bathroom fixtures and components in Slovakia. Operating with thousands of products spanning faucets, shower enclosures, bathtubs, sinks, WC modules, and bathroom furniture, the company faced a familiar e-commerce challenge: helping customers find the right products in a vast and technically complex catalog.

Key pain points included:

• Technical Complexity — Bathroom renovations involve compatibility concerns (pipe sizes, mounting types, water pressure requirements) that overwhelm typical online shoppers
• High Consideration Purchase — Bathroom fixtures are significant investments requiring confidence in quality, fit, and style matching
• Customer Support Volume — Repetitive questions about product specifications, compatibility, and installation consumed valuable support team resources
• Conversion Drop-off — Uncertain shoppers frequently abandoned their sessions, unsure which products would work for their specific bathroom setup
• Limited Expert Guidance — The existing shopping experience lacked the consultative expertise customers would receive from a specialized bathroom consultant

The Goal

Heavenshop sought a solution that could replicate the expertise of a professional bathroom consultant in the digital environment—providing personalized recommendations, answering technical questions instantly, and guiding uncertain shoppers toward confident purchase decisions, all while operating 24/7 without scaling support costs.

The Solution

Selzee: An AI Bathroom Consultant That Never Sleeps

Selzee is an AI-powered shopping assistant designed specifically for e-commerce, functioning as a virtual bathroom consultant that actively engages visitors, recommends products, and resolves customer inquiries in real-time.

Core capabilities deployed for Heavenshop:

• Personalized Product Recommendations — AI trained on the full Heavenshop catalog to suggest fixtures based on customer bathroom dimensions, style preferences, and technical requirements
• Technical Compatibility Guidance — Ability to explain mounting types, water connections, and product specifications in simple terms
• 24/7 Availability — Round-the-clock support ensuring no customer inquiry goes unanswered, regardless of time or shopping hours
• Slovak Language Support — Native assistance for Slovak customers with localized product knowledge
• Seamless Integration — One-line code implementation with daily retraining on updated product catalog

Implementation Approach

The deployment followed Selzee's streamlined integration process:

• Catalog Ingestion — Full synchronization with Heavenshop's extensive product database, including technical specifications, compatibility data, and installation requirements
• Brand Voice Training — AI calibrated to match Heavenshop's helpful, expert brand personality
• Use Case Configuration — Custom workflows for common customer journeys including bathroom renovation planning, product comparison, and order support
• A/B Test Setup — Rigorous split-testing framework to measure true incremental impact

The Methodology

A/B Test Design

To ensure statistically rigorous measurement of Selzee's impact, Heavenshop implemented a controlled A/B test:

The near-equal distribution between groups confirms proper randomization and eliminates selection bias concerns.

Metrics Measured

• Conversion Rate (CR) — Percentage of visitors completing a purchase
• Average Order Value (AOV) — Mean transaction value per order
• Revenue Per Visitor (RPV/ARPU) — Total revenue divided by total visitors
• Chat Conversion Rate — Conversion rate specifically for visitors who engaged with the AI assistant

The Results

Performance Comparison

The Power of Engaged Shoppers

This demonstrates the transformative power of proactive engagement: when customers receive personalized guidance at the moment of uncertainty, they convert at dramatically higher rates.

Understanding the Numbers

The 11.41% RPV improvement represents the impact of better conversion working across the entire visitor base. While AOV remained stable, the increased conversion rate drove meaningful revenue gains.

Breaking down the $394,000 projected uplift: During the A/B test, only 50% of traffic saw Selzee. With full deployment to 100% of visitors, the annual revenue impact doubles. This figure represents the additional annual revenue Heavenshop can expect from deploying Selzee across their full traffic base.
