We bill customers for power platform and power platform component sales based on certain contractual milestones being reached. We bill service agreements based on the contract price and billing terms of the contracts. Generally, our Advanced Technologies contracts are billed based on actual revenues recorded, typically in the subsequent month. Some Advanced Technologies contracts are billed based on contractual milestones or costs incurred. Unbilled receivables relate to revenue recognized on customer contracts that have not been billed. The Company had no allowance for doubtful accounts as of April 30, 2022 and October 31, 2021. Uncollectible accounts receivable, including unbilled receivables, are charged against the allowance for doubtful accounts when all collection efforts have failed and it is deemed unlikely that the amount will be recovered or if the Company calculates expected credit loss estimates based upon forward-looking information.
