B2b and b2c in case of service

Sashi (Service) (17 Points)

12 August 2017  

Sir,

Ours is a firm providing services of Catering, renting of immovable property (Commrcial) and some assistance like Event Decoration etc

which are taxable under GST @ 18%.   My question is  our business being a service ( Catering to Marriage Function / parties), I think

it is end user, thus treated to be as custoemr (B2C) but few customrs ( business men) are registered and have GST Number, they argue that they

can take input credit, and asked us to issue bill as usual that is b2b for registerd person.  How it is possible  them to take advantage of ITC,

Please clarify,   Please also let us know while making bills unregistered persons are to be treated customer or regular ?  If we add them regular gstr1 is not prepared and showing some error?

Confused  .. seeking help

 

Thanks

Nair
