Accounts Receivable

We grant credit to our customers located within the United States of America; and do not require collateral. Our ability to collect receivables is affected by economic fluctuations in the geographic areas and industries served by us.  Reserves for un-collectable amounts are provided, based on past experience and a specific analysis of the accounts.  Although we expect to collect amounts due, actual collections may differ from the estimated amounts. As of March 31, 2019, and December 31, 2018, we had a reserve for potentially un-collectable accounts of $57,000.  Five (5) customers accounted for approximately 94% of accounts receivable at March 31, 2019. Our trade accounts primarily represent unsecured receivables.  Historically, our bad debt write-offs related to these trade accounts have been insignificant.
