Combining multiple individual SKUs into a single package or bundle before shipping.

Why It Matters

Kitting enables bundle sales, subscription boxes, and gift sets without creating new product SKUs. Pre-kitting bestselling bundles speeds fulfillment; on-demand kitting provides flexibility. The choice between them depends on volume and predictability.

Practical Example

Scenario

A skincare brand sells a popular 'Starter Kit' containing 4 products.

Calculation

On-demand kitting: pick 4 items + assemble = 4 minutes/kit. Pre-kitted: pick 1 kit = 30 seconds. 500 monthly kit orders × 3.5 minutes saved = 29 hours/month saved

Result

Pre-kitting the bestselling bundle saves $600/month in labor and reduces shipping errors from 3% to 0.5%.

Pro Tips

1Pre-kit high-volume, consistent bundles for efficiency
2Use on-demand kitting for custom bundles or low-volume combinations
3Create a 'kit' SKU for inventory tracking even if components have individual SKUs
4Include packing instructions/QC checklists for consistent presentation

Common Mistakes to Avoid

Pre-kitting too much inventory that doesn't sell as bundles (can't undo easily)

Not tracking kit components' inventory separately (stockout surprises)

Inconsistent kit presentation when multiple people assemble

Frequently asked questions

Pre-kit when: volume is high (50+ kits/week), bundle is consistent (doesn't change), and you have storage space. Kit on-demand when: bundles vary (customizable), volume is unpredictable, or you can't afford to tie up component inventory in pre-made kits.

Two approaches: 1) Create a 'kit SKU' and deduct component inventory when kit is assembled (pre-kit). 2) Sell the kit but deduct component inventory at order time (on-demand). Most inventory systems support both. Key is preventing overselling of components needed for kits.
