Automatic debit to customer, if customer fails to pay within due date

Question

Dear Gurus,
i belong to consumer products company. we give incentives to our customer in form of different discounts e.g. booking discount, monthly discount, trade discount, foreign tours etc etc.
At present our payment terms ranges 30 to 60 days and we book invoice at gross rate and above mentioned discounts are subject to clearance of payment so we create accrual of discount in invoice and if payment is received within due date discount is given to customer through credit memo process
Accounting entries are as follow ---example
At the time of invoice
AR                                                10,000   Dr
discount expense                          2,000   Dr
Sales                                                               10,000      Cr
Discount provision                                             2,000     Cr
as payment is cleared credit note is issued
Discount provision                         2,000 Dr
AR                                                                    2,000     Cr
now our credit control deparment says its not easy to handle separate credit notes to customer. there wish is as follow
At the time of INvoice
AR                                                 8000   Dr
Discount Expense                        2000   Dr
Sales                                                              10,000 Cr
and if payment is not received on time, system should raise debit note automatically by passing this entry
AR                                            2000 Dr
Discount Expense 2000 Cr
please advice in this regard
