Note 5.  Accounts Receivable

Credit is extended based on the evaluation of a customer’s financial condition and collateral is generally not required.  Accounts that are outstanding longer than the contractual payment terms are considered past due.The Company writes off accounts receivable when they become uncollectible; payments subsequently received on such receivables are credited to the allowance for doubtful accounts.  At both December 31, 2013 and September 30, 2013, the balance in the allowance for doubtful accounts was $97,950.  See Note 7, “Major Customer Concentration” for further information regarding accounts receivable.
