A variation is a choice for one product, such as a small or large shirt.
- Open Inventory > Variations.
- Choose Add Variation and enter a name, such as Sizes.
- Under Varieties, use Add variant to enter values such as Small and Large. Choose Save Variation.
- Open the Groups tab. Choose Create Item Variations and select the source inventory item.
- Select the values, then choose Next: Preview Generated Items.
- Check the items, prices, and stock. Each new item starts with the source item's stock quantity and online-sale setting. The quantity is not split between sizes or colors, and this preview does not let you edit stock. Check the source settings before creating online items. The Create button shows how many items will be created. Use it only when the preview is right.
Before selling the new items, edit each item in Inventory so its quantity matches the stock you have.
Use Groups to edit linked items later. Add Existing Item links an item already in Inventory. Generate Variations Only lets you preview missing items for the group. Check each item's barcode and choose Save Group after editing the group. Check that each value is linked to the correct item.
