there is a flaw with your price list
You cant have just 2 ways of discounting , what if there are more than 200 items that needs discounting and same item discount is not valid for other customer. and if i select price list that will discount my whole sales voucher which i obviously dont want. it shud be item specific, and there should be provision for making group for particular item and that list should have discount, so when i add pricelist , any item that falls under that price list will be discounted and all other items in sales voucher should have normal prices. please check tally erp for same, where you can give discount at individual level also and at item level also, and also if you add anything outside that list, discount will not be applicable. cant use zoho, as its useless for distributors and wholesalers
