Red Flag? Accounts Receivable skyrocketed to $711,xxx from $66,xxx the year before. Is that because of revenue growth or because collections are slow?
That's worrisome for several reasons, especially:
"Concentration of accounts receivable "Two customers accounted for 64% of accounts receivable as of December 31, 2021. There were no customers that accounted for more than 10% of accounts receivable as of December 31, 2020 except as noted in the related party transactions."
