Urgent Help request (accounting module)

Dear @isoscent
I really appreciate your help and support.
I was wondering why i cannot use under Billing | Payment under Sales tax to make a payment on 31 Dec 2021 (with the amount of credit needed) please correct me if i was wrong with this workaround

for Cheques/Third parties I’m thinking of creating invoices for each Cheques/Credit/debit on 31 Dec 2021 (linked to the cheques customers )

waiting for your advice
