Hi there, @derjamREM.
Thanks for reaching out to us. I understand the importance of having the option to automatically apply expenses to various classes in QuickBooks Desktop (QBDT). Currently, this feature is unavailable.
Our platform allows you to easily assign expenses to specific classes by selecting the appropriate class during the expense entry process. This way, you can accurately track and categorize your expenses according to your desired classes. Thus, I recommend manually entering the expenses into classes in QBDT. While this may require a bit more effort on your part, it will ensure accurate tracking and organization of your expenses.
In the meantime, feel free to take a look at Set up and use class tracking in QuickBooks Desktop for more details about the class.
You can use this information on how to filter, sort, or total reports by Class in QBDT. Also, here's a reference that provides more information about the class: How to use class tracking in QuickBooks.
