Common Problems with Billing Codes
"Project" Tab Is Not Visible in the Admin Interface
You do not have a license with the "Project tracking" feature.
Listing and Displaying Billing Codes Is Too Slow
Check whether you have followed the guideline for creating billing codes.
Too Many "Orphaned" Billing Codes
The file that defines billing codes must also contain all billing codes up to the root. If there is no such path, then the importer will not be able to enter a billing code into the tree.
