Hi,

We regularly receive cash payments from customers. Many times the customer does not have an exact change & they round it off to the nearest value & rest is considered as a discount.  We particularly face an issue recording that discount, as there is no discount field on the payment, received page for EMEA. So we have to manually edit the invoice & enter the correct amount for each. As per ZOHO support discounts can only be added to individual line items as per VAT rules. 

This becomes very difficult as we have many transactions & it happens the same with most of them.

Is there a way to add a custom button that will apply the discount on the payment received page?

Any help would be greatly appreciated.
