Example Raju at the counter tries to bill 10 packets of Tata Salt 1 kg. Only 6 are in stock because today's purchase is not entered yet. With Dont Allow Negative Stock, the bill stops at 6. The owner enters the purchase first, and the bill goes through.
Which one to pick A shop that enters every purchase on time should choose Warn and ask me or Dont Allow Negative Stock. A shop that bills first and enters purchases at night can choose Warn me, then check the Stock Report with the Negative Stock tick every evening.

Questions and answers

The bill says "Stock is Going Negative". What should I do?

The item has less stock than you are billing. Check whether the purchase is entered. If it is a genuine sale, enter the purchase, or answer Yes if your setting allows it.
