    I am a service provider.
    My annual turnover is FAR LESS than Rs. 20.00 lakhs.
    As per Sec. 22, I need not obtain the Regn. number.
    But my clients, who have computerised their data-base, want me to mention the GSTN in their data-format.
    I am threatended that I will loose my clients, due to no fault of mine.
    Kindly advise me, what should I do to tide over this hassle.
    What are Govt. guidelines in such cases.
    Does the Govt. want small and tiny service providers to fall in line with farmers.
