Adding Sub account categories

Re. my machinery repair business, I need to add sub accounts to sales so that I can differentiate between labour costs, parts, sub contract costs etc.
Would I be able to do this under ‘sales’ account or would it need to be somewhere else,
Than you in advance

You can create account groups. But the things you describe are expenses, not categories of income.

Thank you Tut, I’m new to this!. what I really want to do is be able to list on a customer invoice the type of parts used and have them appear on an invoice.

And to have them appear in a drop down box when completing invoices

Then you need to create inventory items or non-inventory items. These questions are all answered in the Guides:
