Does the credit limit apply to invoices from Project Billing?

Summary:

The customer uses Project Management as the main source of AR transactions. They are interested in the credit limit feature available in AR (the fields available on the customer profile class and related setup). I've only seen it applied to invoices from Order Management. Is the credit limit checked during Import AutoInvoice when the source is Project Billing (same as it's done for the Source DOO)?

Content (please ensure you mask any confidential information):

The customer uses Project Management as the main source of AR transactions. They are interested in blocking the creation of invoices in AR if the credit limit has been exceeded. This implies they would need to fill the relevant Credit related info in the customer profile class.
