NOTE 12 – CONCENTRATIONS

Concentrations of credit risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of trade accounts receivable and cash deposits.

The Company places its cash in banks at levels that, at times, may exceed federally insured limits. There were no balances in excess of FDIC insured levels as of December 31, 2019 and 2018. The Company has not experienced any losses in such accounts through December 31, 2019.

Geographic concentrations of sales

For the year ended December 31, 2019, approximately 80% of all sales were in the United States. No other geographical area accounting for more than 10% of total sales during the year ended December 31, 2019. For the year ended December 31, 2018, all sales were in the United States.

Customer concentrations

For the year ended December 31, 2019, two customers accounted for approximately 25.9% of total sales (13.9% and 12.0%, respectively). For the year ended December 31, 2018, three customers accounted for approximately 43.3% of total sales (11.2%, 13.9% and 18.2%, respectively). A reduction in sales from or loss of such customers would have a material adverse effect on the Company's consolidated results of operations and financial condition. At December 31, 2019, three customers accounted for 58.3% (15.8%, 25.5% and 17.0%, respectively) of the total accounts receivable balance. At December 31, 2018, two customers accounted for 82.4% of total accounts receivable (24.1% and 58.3%, respectively).

Vendor concentrations

Generally, the Company purchases substantially all of its inventory from two suppliers. The loss of these suppliers may have a material adverse effect on the Company's consolidated results of operations and financial condition. However, the Company believes that, if necessary, alternate vendors could supply similar products in adequate quantities to avoid material disruptions to operations.
