Build E-commerce AI That Actually Fits Your Business

Off-the-shelf AI is cheaper upfront but has scaling costs. Custom AI is a one-time build that becomes more cost-effective over time.

By Parker Gawne, Founder at Syntora|Updated Mar 5, 2026

Syntora offers specialized engineering engagements to develop custom AI solutions for e-commerce, such as dynamic pricing or advanced product recommendations. By leveraging robust data analysis and modern ML architectures, Syntora designs systems tailored to unique business rules and data. This approach helps e-commerce businesses achieve competitive advantages beyond off-the-shelf tools.

Custom AI is generally more effective when your business rules, data sources, or optimization goals are unique. For instance, while a basic product recommendation engine might leverage an off-the-shelf application, sophisticated dynamic pricing that integrates specific inventory levels, real-time competitor prices, and granular demand forecasts typically requires a custom model.

Syntora specializes in designing and building custom AI solutions for complex e-commerce challenges. The decision to pursue a custom solution depends on the specific problem's complexity, the volume and uniqueness of your data, and the required integration points with your existing systems. A typical engagement would start with a discovery phase to audit your current data and processes, defining a clear scope and expected outcomes. The client would provide access to their sales data, product catalogs, and key stakeholders to inform the model design.

What Problem Does This Solve?

Most stores start with a Shopify app for product recommendations. They install in minutes but offer limited control. Their AI often uses a simple rules engine based on data aggregated across all their customers, not just your store. This means a shop selling niche cycling gear gets recommendations influenced by trends from fast-fashion brands using the same app.

More advanced platforms like Nosto or Dynamic Yield offer personalization but come with high monthly minimums and long-term contracts. A 15-person business doing $3M in revenue cannot justify a $2,500 per month fee for a single feature. Their pricing model often scales with your traffic or revenue, penalizing you for growth and eating into your margins.

The core failure is that these tools cannot access your unique business logic. You cannot tell them to prioritize high-margin products or to recommend accessories before suggesting another primary product. This leads to generic recommendations, a 1.2% click-through rate, and a user experience that fails to capture your brand's expertise.

How Would Syntora Approach This?

Syntora would begin an engagement by performing a comprehensive data audit. This involves integrating with your existing e-commerce platforms, such as Shopify or BigCommerce, to extract 12-24 months of order history and your full product catalog. This data would be securely ingested into a dedicated Supabase database. Our engineers would then use Python and the pandas library to analyze this raw data, identifying key purchasing patterns, seasonal trends, and customer segments. This foundational analysis delivers a data audit report, providing a clear understanding of your data landscape before any model development commences.

Leveraging this prepared data, Syntora would design and train a robust recommendation engine. For established products, a collaborative filtering model, often implemented with the LightFM library, would learn nuanced user-product interactions, surpassing basic "people also bought" suggestions. For new products or those with limited sales data, a content-based model utilizing SentenceTransformers would analyze product descriptions to identify and recommend similar items. This hybrid strategy ensures comprehensive recommendations across your entire product catalog.

The developed machine learning model would be encapsulated within a high-performance FastAPI application. This API would be deployed as a serverless function on AWS Lambda, an architectural choice that offers scalability and cost-efficiency by only consuming resources when requests are active. The system would be designed to expose a clean API endpoint, returning recommended product IDs in response to user requests, for example, on a product page view. Syntora would provide comprehensive API documentation and support for your frontend team to integrate these recommendations directly into platforms like a Shopify Liquid theme.

For ongoing operational visibility, the deployed system would incorporate structured logging via structlog. While a full Vercel dashboard might be part of the client's existing observability stack, Syntora would ensure logging is compatible with common monitoring tools. An automated retraining pipeline would be established to refresh the model weekly or on a defined schedule using the latest order data, maintaining recommendation relevance and system performance without requiring manual intervention. The deliverable is a self-sustaining, production-ready system.

What Are the Key Benefits?

  • Your Data, Your Competitive Edge

    Off-the-shelf tools pool data from thousands of stores. Our models train only on your sales history, capturing the unique buying patterns of your specific customers.

  • Pay Once, Not Per Order

    A one-time development cost and minimal monthly hosting on AWS Lambda. No revenue-sharing or traffic-based fees that punish you for growing your business.

  • You Own The Source Code

    You receive the complete Python source code in a private GitHub repository. There is no vendor lock-in; you can modify or extend the system yourself.

  • Faster Than Any Shopify App

    Recommendations are served from a dedicated AWS Lambda function in under 150ms. This avoids the page-load slowdown caused by heavy third-party Shopify scripts.

  • Integrates, Doesn't Dictate

    We build a simple API your developers can call from your Shopify or BigCommerce store. No new dashboards or platforms for your team to learn.

What Does the Process Look Like?

  1. Week 1: Data Connection and Audit

    You provide API access to your e-commerce platform. We extract historical order and product data and deliver a data quality report outlining the modeling strategy.

  2. Weeks 2-3: Model Development and Review

    We build and train the core AI model. You receive a performance summary showing how the model identifies product relationships from your own sales data.

  3. Week 4: API Deployment and Integration

    We deploy the model as a production API. We provide your developers with API documentation and a test key to begin integration into your store's theme.

  4. Weeks 5-8: Monitoring and Handoff

    We monitor the API for performance and accuracy for 30 days post-launch. You receive a final runbook with instructions for monitoring and retraining.

Frequently Asked Questions

What does a custom e-commerce AI project typically cost?
Pricing depends on data complexity and the number of integrations. A product recommendation engine using clean Shopify data is straightforward. A dynamic pricing model pulling from three competitor sites is more involved. We provide a fixed-price proposal after a 30-minute discovery call where we review your specific requirements. Book a call at cal.com/syntora/discover.
What happens if the recommendation API goes down?
The API is on AWS Lambda, which is highly resilient. If an outage occurs, the API endpoint will fail to respond, and your store should gracefully hide the recommendation section. We use UptimeRobot for external monitoring, which sends an alert so we can restore service, typically within an hour. This is covered during our initial monitoring period.
How is this different from using a tool like Klayvio for personalization?
Klayvio is excellent for rule-based marketing automation. Our systems build predictive models. For example, Klayvio can segment users who bought a product; our model can predict which product they are most likely to buy next and serve that recommendation in real time on your site. We often integrate our models to send data into tools like Klayvio.
Do we need an engineer on our team to maintain this?
No. The system is designed to run with minimal intervention, including automated weekly retraining. We provide a runbook that a non-technical person can follow for basic monitoring. For code-level changes or new feature development, you would need a developer, but routine maintenance is handled by the system itself.
How do you measure the ROI of a project like this?
We help you set up A/B testing during integration. Half your traffic sees old recommendations (or none), and half sees the new AI recommendations. We track metrics like click-through rate, add-to-cart rate, and average order value for each group. The difference in revenue between the two groups over 30 days provides a clear ROI calculation.
Can you build other types of e-commerce AI?
Yes. We have built inventory forecasting models that reduce overstocking, dynamic pricing engines that adjust to competitor prices, and customer service bots using the Claude API to answer product questions. The core process is the same: connect to your data, build a custom model, and deploy it as a lightweight API for your business.
