Hi, 

When recording a payment to vendor, I need to apply additional discounts for making payments in certain days, can you please advise how to do that? 

For Example: 

Bill due is $10,000.00

- (Minus) Discount for Promo applied at the time of placing purchase order 4%

- (Minus) Making Payments within 10 days (take additional 2%) 

= Payment to be made $9,400.00

Please help and advise...
