On our last purchase order, the bank automatically deducted USD20 as handling charges which was supposed to be paid by your company. On this new purchase order, we can reimburse USD100 as bank charges but not that USD20. As such, all your company needs to do is to provide a debit note of USD80.
Please be informed that we are paying the bank charges for this new purchase order, but the handling charges of USD20 still will be automatically deducted from the order amount. Thank you.

Because on an order form, the bank deducted handling charge UDS20 automatically, is bank charges which the expensive department deals with, we may repay BANK CHARGES USD100 in this order form, but USD20 will repay no longer, therefore expensive Si Zhixu provides DEBIT NOTE USD80 then.
But this new order form's BANK CHARGES USD100 we give as required by rule unmistakably, but will still have the bank charges approximately USD20, this expense will deduct automatically in the order form am
