Please confirm to us,

Note 3 - Accounts Receivable, page F-20

6.       We note from page 62 that the increase in accounts receivable during

revise the note to
         address the following:

                Briefly describe the circumstances relating to your extending
that customer   s credit
              terms from 90 days to 120 days.
                Disclose an aging of your accounts receivable at September 30,
2021 in tabular form
              and show the allowance for losses related to each age group of

7.       We note from page 76 that for customers located in certain regions you
have established
         certain measures, such as factoring arrangements, to protect you from
excessive exposure
         to credit risks. Please revise the notes to financial statements to
describe your factoring
         arrangements and how you account for them. In addition, revise the
Liquidity and Capital
         Resources section of MD&A to discuss the impact of your factoring
arrangements on your
         liquidity position during each reported period and disclose any
related known risks and
         trends.
8.       You disclose here that you recorded bad debt expense of $96,166 in
fiscal 2021. Please
         reconcile this disclosure to the bad debt expense adjustment of

         statement of cash flows for the year ended September 30, 2021, or
revise your financial
         statements to resolve the inconsistency.
