Summary:

Recalculate WHT during Invoice Payment for Prompt Payment Discount Applied to the Invoice

Content (please ensure you mask any confidential information):
Our customer currently has a requirement to compute for the WHT during both invoicing and payment time.

During invoicing, WHT should be computed based on the gross invoice amount and be accounted.

Payment term of the invoice includes a discount if it is paid within the discount window.

If the invoice is paid within the discount window, a prompt payment discount should be calculated during payment for which another WHT calculation should happen specifically for the discount.

This additional WHT calculation during payment time should be a reduction to the original WHT computed during invoicing.
