1. My company is selling goods to customer. Whatever they are selling, that products will have validity date. If the material is damaged within the validity date then company will repair that goods and will be provided to customer with invoice 0 amounts.
2. If the damaged goods are under warranty if company is unable to fix / rectify the problem then company will provide a new material with invoice zero amounts.
3. If the damaged goods are out of validity then company will estimate that goods cost and will take that goods and will provide new material with remain amount.
4. Some time customer came with damaged good and technical guy will check and will immediately provide to customer because it is not having any problem and the problem is at the end of customer level.
Your comments are valid to me on this.
