GST worked out for you
CGST and SGST inside your state, IGST outside it, with HSN codes picked from the official list.

Questions shop owners ask

Do I need a GSTIN to start?

No. Without one, Lekkasari issues Bills of Supply without GST. Add your GSTIN later and GST is charged from your next invoice.

Can my CA see my accounts?

Yes. Add your CA as an Auditor. They can see everything and download reports, but cannot change anything.

Does it work on my phone?

Yes. It runs in the browser on any phone, tablet or computer, in light or night mode.

Can I file GSTR-1 from it?

Lekkasari prepares the GSTR-1 tables as files for the GST offline tool and shows your GSTR-3B figures. Check them with your CA, then file on the GST portal.

What if I make a mistake on an invoice?

Drafts can be edited freely. An issued invoice can be cancelled with a reason, and paid invoices are corrected with a credit note, the way GST expects.
