Regarding AR write off, Create a receipt source as Write Off with your write off account and apply it to all your invoices. If you are looking for multiple write-offs together then that's not available yet but we plan to have writeoff as a line item in Receipt line in version 0.5.1
Please use inoerp forum for http://inoideas.org/ for such generic questions
