Creating an invoice that includes one off items for a job, is it possible to not have to 'create' every single item and instead just write it in the line?

I'm here to share some information in creating an invoice, userearthcorelandsca.

When creating an invoice, it is advisable to record the item. It helps us to track and identify which items does the income comes from.

If we don't record the products, the system will automatically recognize, Sales as the default items on the invoice.
