It is possible to set a minimum order value. If you set this up, the customer can only definitively place an order when the shopping basket value exceeds the set limit.
You can set the minimum order value in 2 steps in the following location:
"Starting point > My Webshop > Settings > Ordering process & stock > Settings ordering process".
1) Activate "Yes, as from a minimum order amount under "Ordering Allowed"
2) Under "Minimum Amount for an order to be allowed" enter the minimum order amount at which you want to allow ordering.
