Accounts Receivable, net	Accounts Receivable, net The Company records accounts receivables for agreements where amounts due from customers are contractually required and are non-refundable. The carrying amount of accounts receivables is reduced by a valuation allowance that reflects the Company’s best estimate of the amounts that will not be collected. Net accounts receivable is comprised of the monthly, quarterly, or annual committed amounts due from customers pursuant to the terms of each respective customer’s agreement. Account receivable balances include amounts attributable to deferred revenues. The Company’s accounts receivable balances included $89,000 of unbilled receivables associated with contractually committed services provided to existing customers during the twelve months ended October 31, 2021, which will be invoiced subsequent to October 31, 2021. As of October 31, 2020, the Company’s accounts receivable balance included $53,000 of unbilled receivables associated with contractually committed services provided to existing customers. The Company has a history of successfully collecting all amounts due from its customers under the original terms of its subscription agreements without making concessions. However, during fiscal year 2020, several customers requested, and the Company agreed to, the suspension of certain services to those customers, or the provision of services free of charge during a specified period of time. Additionally, one customer requested extended terms of payment, which the Company also accepted. The Company believes that these decisions were in the best interests of the Company as a partner to the aviation industry and will benefit the Company in the longer term. The Company continues to believe that its products and professional service engagements are critical to the efficient operation of the air transportation market. The provision for doubtful accounts was $183,000 and $948,000 as of October 31, 2021 and 2020, respectively. In addition to reviewing delinquent accounts receivable, the Company considers many factors in estimating its reserve, including historical data, experience, customer types, credit worthiness, and economic trends. The Company monitors its outstanding accounts receivable balances and believes the provision is adequate.
