Stop Stockouts and Cut Costs with AI Inventory Automation
An AI automation agency builds forecasting models that reduce stockouts and prevent overstocking. This cuts carrying costs and increases revenue by ensuring top-selling products are always available.
Syntora designs and engineers custom AI inventory management systems for e-commerce businesses. Our approach focuses on robust data integration, advanced forecasting models like LightGBM, and scalable cloud deployments using AWS Lambda. We deliver tailored solutions that optimize inventory, reduce stockouts, and integrate seamlessly with your existing operations.
The complexity of such a system depends heavily on your existing data quality and the number of SKUs. A store with two years of clean Shopify sales history, stable supplier lead times, and 500 SKUs represents a more straightforward technical build. A brand with 10,000 SKUs, multiple suppliers, and inconsistent historical data would require more extensive data engineering and feature development. Syntora's engagements for this type of solution typically involve a discovery phase, system design, development, and a handover, ensuring the client gains a robust, custom-engineered tool.
What Problem Does This Solve?
Most e-commerce stores rely on the simple low-stock alerts built into Shopify or BigCommerce. These systems trigger a notification when inventory drops below a static number, like 50 units. This approach fails to account for seasonality, supplier lead times, or changes in demand from a marketing campaign. The alternative is manual forecasting in a spreadsheet, which is time-consuming and prone to human error.
A CPG brand we worked with used a simple reorder point for their best-selling product. In November, a TikTok video went viral, and they sold 300 units in one day. The low-stock alert triggered too late. With a 14-day supplier lead time, they were out of stock for two weeks during the crucial Black Friday period, losing an estimated 400 sales. The static threshold system failed because it could not see the sudden demand trend.
These systems are fundamentally reactive, not predictive. They look at the current inventory level, not the rate of change in demand or external factors. A spreadsheet cannot model the complex, non-linear relationships between sales velocity, marketing spend, seasonality, and website traffic. This leads directly to missed revenue from stockouts and wasted capital on overstocked slow-movers.
How Would Syntora Approach This?
Syntora's approach to e-commerce inventory management starts with a discovery and data audit phase. We would establish secure data connections, integrating with your Shopify API for historical order data, and potentially augmenting this with Google Analytics for traffic trends and your marketing calendar from a Google Sheet or internal system.
The core data processing would utilize Python with the pandas library. Syntora's engineers would clean raw data, handling outlier sales events and engineering critical features like rolling 7-day sales velocity and day-of-week effects for your key SKUs. We have extensive experience building robust data pipelines using Python and pandas for complex financial and operational datasets, applying these proven methodologies directly to inventory data.
A time-series forecasting model, typically LightGBM or Prophet, would then be trained. These models are chosen for their ability to capture seasonal patterns and promotional impacts, aiming for high accuracy in predicting demand for a defined horizon such as the next 30 days. The client would provide historical sales data, supplier lead times, and relevant promotional calendars.
The engineered model would be deployed as a scalable, serverless function using AWS Lambda. An Amazon CloudWatch event would trigger this function on a defined schedule (e.g., every 24 hours) to retrieve latest Shopify inventory, execute the updated forecast, and compute optimal reorder quantities based on supplier lead times stored in a structured database like Supabase.
The system's output would be tailored to your operations, such as a CSV file to your team, a direct update to a Google Sheet formatted as a purchase order, or integration into an existing ERP. For observability, we configure structured logging with `structlog` and implement real-time Datadog alerts. For example, if the model's forecast error consistently exceeds a defined threshold, an alert would trigger for manual review and potential recalibration. Typical engagement timelines for a system of this scope range from 6 to 12 weeks, depending on data complexity and integration needs.
What Are the Key Benefits?
Cut Stockouts Without Creating Overstock
Our models forecast demand for each SKU individually, preventing stockouts on best-sellers while reducing carrying costs on slow-movers by up to 25%.
Daily Purchase Orders in 5 Minutes
The system runs automatically every night. Your team receives a precise purchase order recommendation by 8 AM daily, ending 10+ hours of weekly manual spreadsheet work.
You Own the Forecasting Engine
We deliver the complete Python codebase in your private GitHub repository. You are not locked into a SaaS platform and can modify the system as your business grows.
Alerts When Forecasts Go Wrong
We set up automated monitoring using Datadog. If forecast accuracy for a key product category drops, you receive a Slack alert before it impacts inventory levels.
Connects Shopify, Analytics, and Ads
The model ingests data from your Shopify store, Google Analytics, and even Facebook Ads campaign schedules to create more accurate, context-aware demand forecasts.
What Does the Process Look Like?
Week 1: Data Integration
You provide API access to Shopify and Google Analytics. We pull and audit your historical sales and traffic data, delivering a data quality report highlighting any gaps.
Weeks 2-3: Model Training
We build and test multiple forecasting models on your data. You receive a model performance summary showing backtested accuracy and key demand drivers for your top products.
Week 4: Deployment & Workflow
We deploy the production model on AWS Lambda and connect it to your workflow. You get your first automated purchase order recommendation in a shared Google Sheet.
Weeks 5-8: Monitoring & Handoff
We monitor daily forecasts for accuracy and make adjustments. At the end of the period, you receive a full runbook and system documentation for ongoing maintenance.
Frequently Asked Questions
- How much does a custom inventory forecasting system cost?
- Pricing depends on the number of SKUs, data sources, and the complexity of your supply chain. A business with 500 SKUs and one supplier has a different scope than one with 10,000 SKUs and multiple international suppliers. After a 30-minute discovery call, we provide a fixed-price proposal. Book a call at cal.com/syntora/discover.
- What happens if a forecast is completely wrong and we over-order?
- The system includes sanity checks. If a forecast suggests ordering 10x the historical monthly average for a product, it flags the item for manual review instead of including it in the automated PO. This prevents a single data glitch from causing a major inventory issue. The alert is sent via Slack for immediate attention.
- How is this different from a SaaS tool like Inventory Planner?
- Inventory Planner provides excellent general forecasting but uses a one-size-fits-all model. We build a model trained exclusively on your data, incorporating unique factors like your specific marketing calendar or supplier reliability quirks. You also own the code, so you're not paying a recurring per-order or per-SKU fee that grows as you do.
- What if we don't have 24 months of clean data?
- We can typically build a reliable model with as little as 12 months of consistent sales data. For newer stores with less history, we can supplement the model with data from Google Trends or similar products to capture seasonality. We assess data viability in the first week before the main build begins.
- Does this system handle product bundles or kits?
- Yes. We can model bundles in two ways: either as their own unique SKU or by breaking them down into their component parts. The system can then forecast demand for the components based on the sales velocity of the bundles they are in. This requires mapping your bundle composition, which we handle during the data integration phase.
- Who on my team manages this after you hand it off?
- The system runs automatically and requires no daily management. The provided runbook covers common maintenance tasks, like adding a new supplier's lead time to the Supabase table, which can be done by a non-technical person. Retraining the model is a script that a developer can run. We offer a monthly retainer for ongoing support.
