Dear Querist,
Most ASMT-10 are system generated within little/no intervention by officers. Therefore, the parameters set of trading/manufacture of goods etc.. are not distinguished for service sector by Department leading to such ASMT-10s.
Kindly examine the factual aspects relating to the e-way bill issued by clients of cold storage, both to and from the cold storage. As mentioned by Experts, value of goods in e-way bill will not co-relate with taxable value of service in GSTR-3B.
That being said, one practical approach would be to prepare a reconciliation between each consignment stored in the cold storage during FY (along with to-and-from e-way bill details) and the corresponding service invoice issued for the cold storage. This will help you to convince the officer about the actual factual aspects.
Practically, if some vague reply is given to ASMT-10/ officer is not convinced, it will result in SCN proceedings. Though the SCN may be easily defendable, it is always better to close the proceedings as early as possible.
