Good morning, @Albertmwa. 

Thanks for following the thread. I hope you're enjoying the day so far. I'm happy to provide insight into adding class to bills. 

When assigning class to bills, you'll need to ensure you do so when creating the bill. The option to add class from the bill payment screen is currently unavailable. 

Since the option to assign class isn't available in the bill payment screen, this is why the class isn't reflecting on your reports. However, if you add class to the bill, it will carry over to the report. 

On the other hand, I can see how assigning class to a bill payment would be beneficial for you and your business. I've submitted a feedback request to our product development team, so this can be considered in a future update.
