Hi julie39, 

Thanks for your post! 

The account that the invoices post to will depend on the income account selected on the product/services, you can view or change this to 'Services' by going to Sales > Product/services > Edit > View 'income account' field.

If you change this account here, you'll see an option to 'Also update this account in historical transactions' so that these post to the Services account. 

Get back to us below if you have any further Q's. :smiling_face_with_smiling_eyes:

Thank you for your help.  Very much appreciated.
