Uncollectible Invoice Status

A new status should be added to invoices, allowing merchants to mark them as "Uncollectible." When marked as uncollectible, the invoice amount should be removed from the Total Accounts Receivable balance. Currently, multiple unpaid invoices are inflating the Accounts Receivable balance, even though the merchant knows those payments are unlikely to be received. The merchant does not want to delete the invoices or add payments just to adjust the A/R balance. Alternatively, the merchant wants to retain these invoices in the system to keep a record of those customers. If a payment is received against any of these invoices in the future, the merchant should have the option to mark the invoice as paid.
