We want to be organized by approval for customers , so that we can give some goods to our close customers as an approval without making bills. And then tag the goods which the customer likes, and make a bill from within the approval , and the other goods should be returned.
Providing Items to customers without actual POS Bill will defeat the purpose of tracking of items; although you can issue the items to the customer as a credit sale. As a workaround you can do the following:
Allow credit sale for the customers you want to do trust business with. Then issue credit sale or Debit Note while tagging all the items. Once the customer decides on the item to retain, take a adhoc deposit for the same customer (only the retained items amount) and adjust the previously issued Debit Note; then save the deposit by issuing another debit note (amount of the returned Items). Finally do a return bill (by activating Return mode ON) of the return items. This time adjust the 2nd Debit Note against the bill and save the bill.
Do let us know if this resolves your requirement.
