Black Friday Inventory Buffer Planning
Running out of stock on your best-sellers during Black Friday is one of the most costly mistakes a Shopify store can make. A 20-30% inventory buffer protects against demand forecast errors, unexpected viral moments, and supplier delivery issues.
| Product Tier | Buffer % | Reasoning |
|---|---|---|
| Hero products (top 3) | 30-40% | Highest demand, most costly to stockout |
| Core range (top 20%) | 20-30% | Significant volume, moderate uncertainty |
| Secondary products | 10-20% | Lower volume, easier to manage |
| Long-tail / niche | 0-10% | Unpredictable, buffer cost high relative to volume |

Buffer calculation formula
Base forecast x 1.25 (25% buffer) = order quantity. For first-year BF: base forecast x 1.4 (40% buffer) due to higher uncertainty.
