Bills receivables a/c

Commission receivables a/c

To H a/c

(Invoice received from H and recorded it as purchases on accrual basis)

Purchases a/c

To Cash a/c

(Paid 100% cash for the above order to S)

Bank a/c 

To Bills receivable a/c

To Commission receivables a/c

(When money is received from H to K)

These are the entries in your books. 

Your credit note sent to H from S is due to purchase returns. Otherwise, it is always a debit note you will receive from S to all customers.

Refer to bills of exchange journal entries for further clarity because the above entries needs further adjustments in regards to H account after he pays cash. Eg. in the example, K is entitled only to commission and should record his variable pay. However, if we imagine that K is actually reselling the goods to H,

H a/c

To Bills receivables 

To Commission receivables a/c

a reconciliation should be done for the above because both of the above receivables are credited and banks should b debited. 

On a second thought, to simplify the process,

Debtors H a/c

To Credit Sales a/c

(invoiced recorded and sales recorded in income statement)

Purchases a/c 

To Cash or creditors S (payables) a/c

(purchased goods or paid in advance to S)

Bank a/c 

To Debtors H a/c 

(cash+commission received in full) 

This should be sufficient for the time being I hope.
