What is causing the Pricebook task to not show up when trying to add it to an invoice?

Problem

The Pricebook task is missing when adding a task to an Invoice. This happens because of its setup in the pricebook.

Solution

Make the pricebook task show up for invoices.

Note: Depending on your account's configuration, you might see one or more of the following:
Items and Pricing instead of Pricebook.
Customer instead of Homeowner.
Procurement instead of Inventory.
The names are different, but everything works the same way. For more, see Commercial Personalization Platform - FAQ.
