Yes, you can set either, minimum cart quantity or minimum order amount ($), or both for the discount to be applied. You can do this by going into Discount Groups and scrolling over to the minimum requirements section (remember it’s optional).
Notes:
1. If minimum cart requirements are not met then our app will not apply any discounts and shipping rates on the checkout page.
2. Minimum cart requirements don't apply to the Net Term orders and Manual Orders.
