1) Firstly you need to obtain IEC because to establish export under GST, IEC is mandatory. In case of goods there are several other documents available like export manifest, shipping bills etc. In case of services there is no custom clearance or shipping bill therefore it is good practice to apply for IEC. It is one time registration and there is no need of renewal each year.
2) As you said you are exporting services to avoid GST in India therefore you need to obtain GST registration because in case of export there are two options available.
- Export with payment of taxes and claim refund of IGST paid on export.
- Export without payment of taxes. For that you need to submit LUT online.
You need to mention your GST No.on the invoices raised by you.
Note: Make sure it is export i.e. consumption of services outside India.
If you have already obtained GST No.,you just need to file LUT online to go for export without payment of taxes.
