Sometimes you may be unable to collect payment on an invoice. This could be the result of a member leaving your space or a payment dispute. You can Write Off any unpaid invoices when you're sure that the invoice amount is uncollectible.
When you Write Off an invoice it will be marked as 'Written Off' instead of 'Paid or 'Unpaid'. The benefit of this is that the amount will be removed from your unpaid accounts and appear as lost income.
Writing off invoices can affect both your bookkeeping and your taxable income so be sure to research whether or not this is the correct choice for you.
