How you guys handle GST and Taxes?

For those of you who actually posted a game on steam, google play store or IOS app store how did you manage the taxes?

I talked with bunch of local CAs and they have no clue about it. All of them giving me different confusing process.

The common thing that all of them said is that we must have a GST regardless of what we are earning from it as it comes under services category. The 15L limit to register is not applicable.
