Invoice gross amount crediting vendor and WHT tax amount debiting the same

Dear experts,

our customer from Pakistan is managing for the first time withholding tax calculated in invoice posting.

For audit purpose, they want  to trace the gross invoice amount (corresponding to the actual amount on the invoice received), by posting it in credit of the vendor account and  posting  the withholding tax amount in debit of the same account.

Please find below an example:

1) Logisitc invoice:

Account               Description                                                         Amount

4xxxxx                  Vendor account                                                 351,912 – (Cr)

4yyyyy                  ST Accruals Supplier                                        302,416.58 [Grouped] (Dr)

6xxxxx                  Spare parts                                                         1,636.58- (Cr)

4zzzzz                  VAT on purch & Imp.                                          51,132+(Dr)               

2) Then as a separate automated process initiated by WHT marker, system would post the following entry, as credit note:

Account               Description                                                               Amount

4xxxxx                      Vendor account                                                    10,226.4+ (Dr)

4wwwww                  W/H S T Payable RTO                                        10,226.4 – (Cr)         

we would need to know if this kind of posting could be correct and feasible.

we proposed standard withholding tax report S_P00_07000134 but they need to post the gross amount on the vendor account.

Thank you.

Best regards,

Sara
