There are different approaches:

1. Create Client components living in a Clients folder that can contain 
invoices. I use this pattern in my book.

2. Create Client components living in a Clients folder that have an attribute 
called invoices that is a folder. This one is used sometimes in Zope 3 core.

3. Create Client and Invoice components that live in Clients and Invoices 
folders respectively and create relationship objects linking them to each 
other. This approach is used by SchoolTool and I like it a lot. You can use 
SchoolTool's relationship package.

Well, different people use different patterns. It's up to you.
