After analyzing our manual inventory system, we identified critical inefficiencies: stock updates took 45+ minutes daily and shortage alerts were reactive, not proactive.
The Problem:
๐ฆ Manual stock entry 4x daily
๐ No real-time shortage visibility
๐ง Late supplier notifications
๐ Disconnected recipe-to-stock calculations
โ Frequent stockouts from poor forecasting
Reality: Managing inventory for 200+ daily orders meant 3+ hours on spreadsheets plus costly last-minute supplier orders.
The Solution:
Built an intelligent n8n workflow automating inventory from entry to alerts:
1. Smart Stock Addition
Scheduled forms (4x daily)
Auto-updates to Google Sheets
Instant Telegram confirmations
2. Predictive Shortage Analysis
Recipe-based calculations (100 units)
Real-time stock comparison
Fuzzy matching for ingredients
3. Automated Reporting
3 daily reports (10:00, 15:00, 20:00)
Formatted HTML emails
Priority Gmail labels
4. Multi-Product Support
Burger + Pizza tracking
Separate recipe databases
Merged shortage reports
๐ฐ Impact:
Time: 3+ hrs/day โ 20 min = 12+ hrs saved weekly
Cost:
Labor: $576/month saved
Emergency orders: $400+/month prevented
Annual ROI: ~$11,700+
๐ฏ Key Lessons:
Predictive > reactive - Calculate needs before shortages hit
Recipe integration - Connect formulas to inventory
Scheduled automation - Regular checks prevent crises
Smart matching - Fuzzy logic handles typos
Tech: n8n, Google Sheets, Telegram, Gmail, JavaScript
The Bottom Line: Simple automation transformed chaotic inventory into a predictive system that saves 600+ hours annually and cuts costs by ~$12,000/year.
