Sets up inventory tracking systems with reorder points, supplier management, and stockout prevention for product-based businesses.
Use this skill when you need to:
DO NOT use this skill for warehouse layout design, shipping logistics, or supply chain optimization at enterprise scale. This is for solopreneurs and small businesses managing product inventory.
INVENTORY MANAGEMENT IS A CASH FLOW DECISION — TOO MUCH INVENTORY TIES UP CAPITAL, TOO LITTLE LOSES SALES. THE GOAL IS FINDING THE MINIMUM STOCK THAT PREVENTS STOCKOUTS.
Understand the current inventory situation before building a system.
| Input | What to Ask | Default |
|---|
| Product count | "How many unique products/SKUs do you carry?" | Under 50 |
| Sales volume | "Roughly how many units do you sell per month?" | Varies |
| Current tracking | "How do you track inventory now? (spreadsheet, software, memory)" | Spreadsheet or none |
| Supplier count | "How many suppliers do you work with?" | 1-3 |
| Lead times | "How long from order to delivery for your main products?" | 2-4 weeks |
| Storage | "Where do you store inventory? (home, warehouse, 3PL, dropship)" | Home or small warehouse |
GATE: Confirm assessment before designing the system.
Build the inventory tracking framework.
## Product Catalog
| SKU | Product Name | Category | Unit Cost | Sell Price | Margin | Supplier | Lead Time |
|-----|-------------|----------|-----------|------------|--------|----------|-----------|
| [SKU-001] | [Name] | [Category] | $[X] | $[X] | [X]% | [Name] | [X] days |
For each product, calculate the reorder point:
Formula: Reorder Point = (Average Daily Sales x Lead Time in Days) + Safety Stock
Safety Stock: Average Daily Sales x Safety Days (typically 7-14 days for solopreneurs)
## Reorder Points
| Product | Daily Sales | Lead Time | Safety Stock | Reorder Point | Reorder Qty |
|---------|------------|-----------|-------------|---------------|-------------|
| [Name] | 5 units | 14 days | 35 units | 105 units | 150 units |
Categorize products by revenue contribution:
GATE: Present the system design for review.
Create the operational tracking templates.

|-----|---------|---------|----------|---------------|--------|-------------|
| [SKU] | [Name] | [qty] | [qty] | [qty] | OK / LOW / REORDER | [date] |
## Supplier Directory

Define alert thresholds:
Deliver ongoing management frameworks.
- [ ] Count A-items and reconcile with tracker
- [ ] Review products approaching reorder points
- [ ] Check supplier lead times (have any changed?)
- [ ] Review slow-moving C-items for discontinuation
- [ ] Update demand forecasts based on last 30 days
- [ ] Review cash tied up in inventory
Provide a basic forecasting approach:
