we have about 3-5 disappear invoice every month, in simple terms is we will lost 2000-4000 dollar every month since invoice just gone, if search by invoice number a totally different invoice will come up with the wrong amount of payment apply to it and the invoice will just "over write" 3-5 times a month??????
when ever inventory below 0 it doesn't allow web user to create invoice.. get the following error message "Some managed inventory items have stock levels below zero (0). Please check your item list" is there any option to disable this? its good idea to get warning but just not allow cause me lot of pain...
