Accounts Receivable	Accounts receivable Accounts receivable consist of trade accounts arising in the normal course of business and are classified as current assets and carried at original invoice amounts less an estimate for doubtful receivables based on a review of outstanding balances on a monthly basis. The estimate of allowance for doubtful accounts is based on the Company's bad debt experience, market conditions, and aging of accounts receivable, among other factors. If the financial condition of the Company's customers deteriorates resulting in the customer's inability to pay the Company's receivables as they come due, additional allowances for doubtful accounts will be required. At September 30, 2018 and December 31, 2017, the Company has recorded an allowance for doubtful accounts in the amount of $31,843 and $73,105, respectively.
