How do I enter a training related expense in QB?

Hi mel14,

If you do not already have an expense account within your chart of accounts that you wish to assign this to then you can create a new one by going to accounting > chart of accounts > new. 

You could create an account, for example Account type - 'Other expense', Detail Type - 'Other expense', *Name 'Training', and then select this account on the category drop-down when entering the expense transaction.
