Note 4 - Accounts Receivable | 6 Months Ended

Loans, Notes, Trade and Other Receivables Disclosure [Text Block] | 4. Accounts Receivable Accounts receivable consists of the following:
|  | May 31, 2025 |  |  | November 30, 2024 |
Gross accounts receivable |  | $ | 13,435 |  |  | $ | 14,278 |
Allowance for credit losses |  |  | (552 | ) |  |  | (1,097 | )
Accounts receivable, net |  | $ | 12,883 |  |  | $ | 13,181 |
We maintain an allowance for credit losses for estimated losses resulting from the inability of our customers to make required payments. The allowance for credit losses is based on a review of specifically identified accounts in addition to an overall aging analysis which is applied to accounts pooled on the basis of similar risk characteristics. Judgments are made with respect to the collectability of accounts receivable within each pool based on historical experience, current payment practices and current economic trends based on our expectations over the expected life of the receivables, which is generally ninety days or less. Actual credit losses could differ from those estimates. Activity in the allowance for credit losses for the six months ended May 31, 2025 was as follows:
Balance at November 30, 2024 |  | $ | 1,097 |
Additions charged to expense |  |  | 40 |
Write-offs against allowance |  |  | (585 | )
Balance at May 31, 2025 |  | $ | 552 |
Substantially all of the accounts receivable written off against the reserve during the three and six months ended May 31, 2025 originated during fiscal 2024. We believe that the carrying value of our net accounts receivable approximates fair value. The inputs into these fair value estimates reflect our market assumptions and are not observable. Consequently, the inputs are considered to be Level 3 as specified in the fair value hierarchy in ASC Topic 820, Fair Value Measurements and Disclosures.
