Hi lmm0211
Time billing is used for businesses that predominantly sell time. You can specify billing rates based on the activity, and the system will use the activity slips to create the time billing invoice. As the workflow for creating this type of invoice is created from an activity slip, it is not possible to create a time-billing recurring transaction.
You mentioned using activity items, can I confirm; are you trying to use items or time billing activities in your invoice? If you want to use items then you can make it a recurring transaction, however, if you want to use time billing then you would need to create it from the activity slips.
Hope that explanation clarifies it for you, but if you still have further questions, feel free to reply with a screenshot of the transaction so I can give you more specific advice.
