I have Account Hierarchy enabled and would like to display the child's company name in the Parent invoice.

Summary 

If you have a setup where the child account’s invoices are sent to the customer, then you can create a subscription-level custom field and input the child’s company name which will then be displayed as a part of the consolidated invoice sent to the parent. 

Solution

The current product behavior is such that the customer name is displayed as a part of the consolidated invoice, and not the child company name.

To achieve this, we have recorded a video here detailing a workaround that can be achieved by creating a subscription-level custom field- https://www.loom.com/share/4929ec11b23244cdb87a4997f0937e3c

Note: This is applicable to configurations with Account Hierarchy + Consolidated invoicing.
