Can I convert an existing listing to a business-only offer?
No. You must create a new offer using a category-specific feed. Learn more
What happens if I provide both a "price" and a "business price" in my business-only offer?
If you provide a "price" as well as a "business price", your offer will be available to all customers on Amazon.com. It will no longer be a business-only offer. Business-only offers can only have a business price ("business-price"), and no regular customer price ("price").
