How to override Price for a product/service?

Hi, I have a client who want’s her bakery set up but there will be a custom field for the pricing. This type of service pricing may be custom as it’s a custom service. At the moment, there is no base price.

Is there anyway to override this? I attempted to create a new pricing field but Webflow won’t allow the default pricing field to be $0.

Thank you,

Dan
