Set a maximum order quantity

A maximum order quantity limits how many units a buyer can purchase in a single order on Amazon. You can set it for one listing, or set a default so that new listings get it automatically.

Set it for one listing

  1. Find the product. On Inventory, for example.
  2. Click Set Max Order Quantity. It's on the row's Link Menu. The popup shows the limit on the listing now.
  3. Enter the new limit and save. Use a whole number of 1 or more.

STK then sends the change to your Amazon listing. It can take a little while to show on Amazon.

Set a default for new listings

  1. Open Settings. Go to the Maximum Order Quantity section.
  2. Tick the fulfilment type you want. Tick Set a maximum order quantity on new FBA listings, the same option for new FBM listings, or both.
  3. Enter your limit. FBA and FBM each have their own box, so they can differ.
  4. Click Update Maximum Order Quantity.

New listings get your limit. A listing that already has a limit is always left as it is.

Apply it to your existing listings

Your default only affects new listings at first. To cover existing listings that don't have a limit yet, tick Also apply the limit to my existing listings (not just new ones) in the same section, then click Update Maximum Order Quantity.

On a large catalogue this can take a little while.

Check the current limit

On Inventory, look for Max Order Qty in the Listing box of any row:

  • A number is the limit on that listing.
  • No limit means there isn't one.
  • A dash means no value is available yet.

If the button is greyed out

Changing a listing needs edit rights on Inventory. Ask the account holder to give you access. See how to add team users.
