Automating Inventory control
Manual inventory control was costing us $820/month in wasted time and errors.
Automation system: $1108 initial, $136/month ongoing.
ROI: 4 months.
Before State
| Pain Point | Time Cost | Annual Cost |
|---|---|---|
| Manual data entry | 5 min per inventory | $8310 |
| Error correction | 11 min | $5082 |
| Status follow-up | 14 min | $13649 |
| Total per inventory | 48 min | $19522 |
System Architecture
Components:
- Trigger layer (webhooks, scheduled jobs, manual)
- Validation layer (Zod schemas, quality checks)
- Processing engine (AI agent + rule logic)
- Integration layer (API, MCP, database)
- Monitoring layer (alerts, audit trail)
Stack: Edge Functions + PostgreSQL + Redis + AI agent via MCP
Timeline
| Week | Deliverable |
|---|---|
| 1 | Map workflow, identify pain points |
| 2 | Build trigger + validation layer |
| 3 | Implement processing logic |
| 4 | Connect integrations, test |
| 5 | Staging review |
| 6 | Go live |
| 7+ | Weekly tuning |
Results (3 Months)
| Metric | Before | After | Change |
|---|---|---|---|
| Time per inventory | 54 min | 11 min | -74% |
| Error rate | 0.9% | 0.34% | -113% |
| Weekly capacity | 21 inventorys | 67 inventorys | +97% |
Mistakes Made
- Starting too big — automate the highest-friction step first
- Too many edge cases — build manual override from day one
- No monitoring — alerts on every failure
- Skipping training — budget 2x the time you think users need
- Hardcoded rules — make logic configurable
Reusable Patterns
- Event-driven triggers
- Zod validation templates
- AI decision framework
- Audit trail pattern
