6 AI Engineering Services for E-commerce Sites That Need Real-Time Product Recommendations

E-commerce runs on relevance.

Show a returning customer the same bestsellers as a first-time visitor. That customer leaves. Send generic SMS blasts about storewide sales. Unsubscribe rates climb. Recommend winter coats to someone in Miami. They do not buy.

Real-time product recommendations fix this. A recommendation engine watches what a user clicks. It learns from purchase history. It adjusts suggestions within the same session.

Here are six firms that build these systems.

What Real-Time Recommendations Require

Most e-commerce platforms offer basic “customers also bought” sections. That is not real-time. That is batch processing updated once a day.

A proper real-time recommendation engine does four things differently:

• Processes clickstream data within seconds, not overnight
• Adapts suggestions when a user switches from phone to desktop
• Filters out-of-stock items instantly instead of showing unavailable products
• Learns from the current session without needing historical data on new users

The firms below build engines that handle all four.

1. GetDevDone™

Ideal for: E-commerce brands running on Shopify with mobile apps and loyalty systems. No internal ML team required.

GetDevDone™ is the engineering partner for digital agencies.

Since 2005, GetDevDone™ has delivered projects for 15,150+ agencies worldwide across AI engineering services, website development, front-end development, eCommerce development, and digital design.

AI engineering services from GetDevDone™ deliver real-time inventory intelligence for e-commerce brands. The firm prevents overselling, keeps marketplace reputations intact, and maintains a 95% client return rate.

A U.S. clothing seller pulled in 18 million dollars yearly. Black Friday discounts created brief sales jumps. Then revenue fell back down. Checkout abandonment sat at 72%. Generic SMS and email campaigns pushed unsubscribe rates higher.

GetDevDone™ built a mobile app using React Native and tied it to Shopify Plus. The app displayed Black Friday products customized to each shopper’s saved items and past clicks. Tapping Apple Pay or Google Pay completes purchases in one motion. Gamified rewards turned spending into sharing opportunities.

Sales conversion rose 22 percent. That brought in an extra 420,000 dollars. Check-out time shortened by 40 percent. Cart abandonment dropped 8 percentage points, recovering around 110,000 dollars in lost sales. The app collected 7,000 downloads across six weeks. One out of every four downloaders bought something again within two months.

For a French fashion retailer with 35 million euros in annual turnover, GetDevDone™ solved a different problem. Inventory overselling hit 7% of orders. ERP disconnects force hours of manual reconciliation each week. Leadership had no visibility into margin performance by channel.

The engineering team wrote a custom Shopify to Odoo connector using Python and Node.js. A Prophet forecasting model in Python ran on AWS EC2 to predict demand. Margin visibility dashboards inside Metabase showed leadership real-time profit data by channel.

Overselling across all SKUs fell from 7 percent to 1.5 percent. Skipping costly SaaS subscriptions saved about 4,000 euros monthly. The client’s IT staff now runs daily operations alone.

2. InData Labs

Ideal for: E-commerce companies with sparse user data that need recommendation engines trained on limited purchase history.

Since 2014, InData Labs has completed more than 200 artificial intelligence projects. Predictive analytics and recommendation systems for e-commerce, fintech, and healthcare are their focus areas.

A company selling products across more than 50 different brands asked for recommendations. Transaction records existed. Product browsing, star ratings, and written feedback did not. Most customers bought something once or twice. Conventional recommendation algorithms could not handle such sparse information.

InData Labs built a system using implicit ALS matrix factorization. The team trained the model to emphasize items purchased multiple times over items purchased once. Additional filters ensured recommendations only showed in-stock products that users had not already bought. The final model could recommend items to a given user, find similar users based on preferences, and recommend similar products.

• Collaborative filtering works even when each user has only a few transactions
• Confidence metrics train models to prioritize repeat purchases over one-offs
• The system filters out already-purchased and out-of-stock products before showing suggestions.

Another client received a campaign management system from InData Labs. The module distributes ad budgets across Shopify, Google Ads, and Google Analytics automatically. Machine learning predicts which campaigns will perform best and moves money without human input. Users build personalized advertising strategies without touching spreadsheet software.

For e-commerce businesses operating with limited user information, InData Labs creates recommendation engines that work with whatever data exists.

3. LeewayHertz

Ideal for: E-commerce brands that want recommendation engines powered by large language models.

The company builds enterprise AI systems for e-commerce, healthcare, and manufacturing. Generative AI applications and custom LLM deployments are their main offerings.

A wine seller based in Switzerland wanted something better than standard collaborative filtering. Wine shoppers look for taste profiles, growing regions, food pairings, and price ranges. A basic “customers also bought” engine cannot tell the difference between “a bold red under 30 dollars that goes with steak” and “a crisp white for summer drinking.”

LeewayHertz developed a custom application using GPT-4. The system pulls from proprietary wine data, including tasting notes, regions, vintages, and customer reviews. It answers plain language questions in real time. Multiple languages work without extra setup. Live inventory checks make sure recommendations only display products currently in stock.

For O’Reilly Auto Parts, LeewayHertz built an e-commerce platform with a vehicle matching system. Shoppers find compatible parts without typing complex search strings. The system recognizes the correct components and displays only parts that fit the customer’s specific car or truck.

For e-commerce brands where customers search by attributes rather than product names, LeewayHertz delivers LLM-powered discovery that understands everyday speech.

4. Vention

Ideal for: E-commerce companies needing dedicated engineering teams embedded directly into their operations.

The firm supplies engineering teams acting as an extension of the client’s own staff. Three thousand engineers work across delivery centers in Europe, Latin America, and Asia.

The AI practice includes machine learning model development, computer vision, NLP, and generative AI applications. For e-commerce clients, Vention builds real-time personalization engines that integrate with existing platforms like Shopify, Magento, and custom storefronts.

• Dedicated teams use the client’s existing project management tools and communication platforms
• Daily standups and sprint planning follow client schedules
• No minimum contract length for team engagement

Vention’s white-label approach keeps the client’s brand on all deliverables. Engineering teams work across time zones to provide coverage for real-time systems that need monitoring outside business hours.

For e-commerce companies that need AI engineering services from a dedicated team that feels like an in-house department, Vention provides embedded engineers who follow existing processes.

5. Ailoitte

Ideal for: E-commerce brands needing AI-powered copilots and sidekicks integrated directly into Shopify stores.

Ailoitte builds AI and mobile applications for e-commerce companies. They released Ailee, an AI assistant for Shopify stores running on ChatGPT technology.

Ailee examines a Shopify store and identifies improvement opportunities. The assistant writes SEO-friendly product descriptions, ad copy for Google and social networks, and email campaign text. It studies sales funnels and checkout abandonment behavior. The system recommends new top-selling products using store data and generates content calendars.

• Ailee Score provides a performance scan showing where the store needs improvement
• Chat interface lets store owners ask questions about their data instead of digging through reports
• Unlimited monthly responses on the Expert plan

Pricing starts free for basic scans and chat credits. The Pro plan runs 29 dollars per month for 250 credits. The Expert plan runs 99 dollars per month for unlimited responses.

One Shopify store owner described Ailee as feeling like having a 24/7 content writer without extra costs. The system turns sales data analysis into a chat-oriented task.

For e-commerce brands already on Shopify, Ailoitte delivers an AI copilot that integrates without engineering work.

6. Instinctools

Ideal for: E-commerce retailers needing recommendation engines that combine historical data with real-time session analysis.

The company grew from a local startup into a global digital transformation firm with over 400 professionals. Fortune 500 clients across ecommerce, healthcare, and manufacturing use their services.

A prescription eyewear retailer came to Instinctools with a problem. Standard product recommendations failed for glasses. Shoppers need suggestions based on face shape, prescription strength, frame material preferences, and budget. Two different people searching for “glasses” want completely different products.

Instinctools implemented an AI-enhanced recommendation system combining historical purchase data with real-time session analysis. The engine tracks what a customer browses during the current visit and adjusts suggestions immediately. The result: revenue per user increased by 73%.

The firm’s CEO, Alexey Spas, notes that e-commerce companies can implement intelligent conversational interfaces that provide real-time assistance at the same level as human support agents.

Deep learning models handle cold start problems when new users have no history

Behavioral relevance tracked across multiple visits, not just the current session

Dynamic bestseller rankings personalized to individual preferences

For e-commerce retailers where standard recommendation engines miss the mark, Instinctools builds custom systems that understand niche product categories.
