Stock for a product is managed in the Inventory section of the product form. Open a product from Products in the main navigation menu and scroll to Inventory.

​
Quantity

With location-based inventory on, you can also manage inventory and view history for a product from the products list.

​
Stock source

Bundles choose how their available quantity is worked out:
  • Managed — the bundle holds a stock figure of its own
  • Derived from constituent items — the figure comes from the items the bundle contains
A derived bundle updates on its own as its parts move. Each item limits the bundle by how many whole bundles it can supply, worked out at each inventory location, so a mixed case is bounded by its scarcest item. Restocking a part makes every bundle containing it available again.
Use Derived for a case you assemble from stock you already hold, and Managed for a pre-pack the warehouse holds under its own SKU.

​
Purchase rules

  • Limit per customer — cap how many of this product a single customer can buy
  • Allow overselling — let customers buy the product even when it’s out of stock
  • Overselling limit — extra units that can be sold on top of the stock level. Leave blank for no limit.
The overselling limit is an allowance on top of the current stock figure rather than a total, so it rebases whenever stock is resynced. Use it when you hold stock somewhere Marzipan can’t see, such as a second warehouse, and want to sell a set number beyond the figure on screen rather than sell forever.
Overselling doesn’t apply to events, untracked products, or bundles taking their stock from constituent items, none of which carry a figure for an allowance to sit on.

​
Low-stock badge

The low-stock badge tells customers when stock is running low. On the product you can:
  • Show or hide the badge
  • Set the threshold at which it appears
  • Set the badge text
  • Or fall back to your global default
Set the badge once under Inventory settings and only override it on the products that need something different.
