Minimums and Multiples
Minimum Order Quantities
You can set minimum order quantities on a per SKU basis. Go to the Variants tab of the Product screen and enter the minimum quantity in the Minimum .... per variant box. The example below will enforce a minimum order quantity of 5 per variant.
You can specify order multiples from the same screen by entering the multiple in the Multiple ... per variant box. The example below will enforce a multiple of 2 per variant.
In both cases, if a customer tries to input quantities that do not meet these requirements, a warning message will be displayed detailing the issue. They won't be able to submit their order until they have amended the quantities.
