Add Product in Booking Customizations with Undefined Price

You may want to upsell a product in your party packages or events but have the price be defined at the time of selling it. Like being able to charge any price for that product. Here's how to do it:

1. First, you will need to create that product in the Register Management and give it any name you want. Click here to read more about how to create a product in Register Management.
2. Then, on the Pricing tab of the product settings, check the box for Undefined Price and click Save. NOTE: this will only allow you to input positive numbers for the price. If you want to be able to put a negative amount, you will need to check the box for "Allow Negative Undefined Price".
3. Now, go to the Event Management > Assignment, and search for the Assignment that your Event Package is using. NOTE: If your event package uses multiple assignments, you will need to do this on each of the assignments for that package.
4. After adding the product to the assignment upsell area, make sure to uncheck the box to "Show in Portal". Unchecking this option means you can only add this product using the Bookings module via employees access and not by customers who book the parties themselves online. The undefined price feature only works on the employee portal, not in the event portal for customers online.
5. Finally, you should be able to upsell that product in the Customizations section of the booking and input the price that you want for that product.
