How to account(financial) for difference between PGI qty and POD qty in Sales?

Hi,

I have done a lot of research on this topic on this forum but not found a complete answer. so posting here.

Lets say the Sales order was for 100 qty, delivery and PGI done for 100 qty. But customer reported through POD that he has received 95 qty. So we did the POD for 95 qty and hence invoice created for 95 qty.

Now, the inventory was reduced for this material by 100 qty as PGI was done for 100 qty. COGS is also for 100 qty. But actually only 95 have been invoiced. So how to financially account for the difference 5 qty? what will be detailed accounting entries? How to deal with it?

Please give your valuable inputs

Regards,
