Frequently asked
Does it generate GST returns?
Yes — GSTR-1 and GSTR-3B JSON offline, plus GSTR-2B reconciliation. Live filing works through your own GST Suvidha Provider (GSP) connection; without it, the same documents export as JSON.
Does it support e-invoice and e-way bill?
Yes — e-invoice (IRN) and e-way bill JSON are generated offline; connect your GSP for live IRN / e-way-bill generation.
Is the tax calculation reliable?
Yes — CGST/SGST/IGST and CESS are derived from the place of supply and HSN/SAC by construction, so a bill is correct without any manual tax entry.
Does it work without the internet?
Yes. It is an offline-first Windows app — billing, returns JSON and your ledger all work offline, with your books stored locally.
