One of our client have made an Import on 30.04.2021 and now they have realized that the commercial invoice ( 1000 $ ) through which they have imported the goods doesn't had shipping and handling charges and they have got another invoice from the overseas vendor with Shipping and Handling charges .The invoice number remained same and the invoice date and the Invoice value was amended to 1250 $. Based on the amended invoice our client have made the payment to overseas vendor and now the Bank people is calling for the BOE proof of the same.
Can the BOE be amended now as its almost an year, and if so can it be done online.
