When to use it
Use a write-off when you have stopped chasing the money and you want the balance closed in Jomioz. Do not use it for these:
The dialog is Internal write-off only. It names the invoice and says the customer will no longer be able to pay it online. Cancel leaves the balance due. Write off internally closes it. Status becomes Bad debt.
Where your country can recover tax on a bad debt, that is a separate button from this dialog. The write-off itself only closes the balance in Jomioz. The recovery steps are in Rules for your country.
