Smart Inventory Automation | Google Sheets + Apps Script + APIs
Mohamed Zahran
This project was implemented in a real-world business environment and delivered measurable improvements for an e-commerce operation.
The solution is built with flexibility and scalability in mind, allowing easy adaptation to any e-commerce platform or industry vertical.
Its robust methodology for inventory synchronization, product visibility control, and error handling is customizable to suit various business requirements and data sources.
The Challenge
Managing inventory across multiple systems—e-commerce storefront, fulfillment center, and meta product catalog—was time-consuming and error-prone.
Manual updates caused:
❌ Inconsistent stock levels between systems.
❌ Products staying visible online even when most sizes were out of stock.
❌ Customer frustration from ordering unavailable products.
The business needed a robust, automated solution to ensure real-time inventory alignment and reduce operational workload.
The Solution
I developed a Google Sheets + Apps Script automation system that integrates directly with APIs from e-commerce storefront, fulfillment center, and meta product catalog.
The solution ensures stock is always consistent and products remain visible only when they are truly available.
Unified connection: APIs link e-commerce, warehouse, and advertising catalog.
Customizable rules: Automatically hide or update products when stock falls below defined thresholds.
Preserved settings: Pricing, visibility, and other critical attributes remain intact during updates.
Simultaneous updates: All systems are refreshed instantly—no lags or discrepancies.
Error-resilient workflow: Replaces manual updates with a fault-tolerant, automated process.
How It Works – Step by Step
Data Retrieval
Pulls live stock data from the fulfillment system.
Cross-checks with e-commerce product database.
Business Rules Application
Applies company-specific logic to determine product visibility.
Automated Sync
Pushes real-time API updates to storefront and catalog.
Ensures key fields (price, visibility) are never lost.
Error Handling & Reporting
Detects and logs discrepancies automatically.
Alerts team for reviews on sensitive changes.
Technical Highlights
Google Apps Script as the automation engine
Google Sheets for dashboard, control, and monitoring
API integration for seamless, multi-platform synchronization
Business rules engine for flexible, company-defined stock logic
Results & Value Delivered
⏱ Saved 2–3 hours of daily manual work (~80% reduction)
✅ Virtually eliminated cross-system errors and mismatches (>95% accuracy)
📦 Customers always see real-time accurate product availability
⚙️ Scalable: easily extendable to new platforms or more complex inventory rules
