To register the expenses of your company without taxes you must access Purchases > Tickets and other expenses. In this section you must register all the expenses of your company that are not invoices or for which you do not have an invoice, but that do affect, in the same way as the expense invoices, the result of your activity.
These non-tax expenses can be payroll, taxes, withholdings, social security or any non-tax expenses.
In this section click on New and you will be able to indicate the Supplier, amount, expense category, description.
To mark that expense as paid, click on the Status field and indicate Paid so you can indicate the user and date of payment.
You can likewise upload Attachments so that they are recorded on that expense.
