First of all, congratulations on becoming a part of the GSTP community. Obtaining the GST Practitioner designation is an excellent opportunity for anyone as it provides him/her with the recognition and the approval from the Government. There is a lot of demand for professionals with GST expertise in the market as most of the businesses running are unorganised and are highly unautomated and need help to comply with the new concepts of Eway bill, to file GST returns and to adapt their businesses according to the GST environment.
See, getting this certification is just the first step in the long journey and it doesn't result in ready-made clients and customers. You have to understand that you still have to compete with the advocates, CA/CS Professionals and other GSTPs. Like any other degree/qualification, your ultimate success would depend on your hardwork, dedication and quality of work. Being a certified practitioner, expert knowledge would be expected from you and for that, you need to ensure that you remain well versed with the constant changes and updations in the GST law. As Mr Ajay has rightly pointed out, Networking plays a really big role. You can make use of this amazing platform like CAClubIndia forum to exhibit your skills and GST expertise as a lot of people looking for services use it.
Obtaining the GSTP certification provides one with the advantage that you get listed as a local area service provider on the Govt. portal. Now, any individual/organisation requiring assistance professional work in your locality can locate and contact you.
