The problem
CAs handle hundreds of clients on deadline, on unreliable internet, with data they can't put on someone else's cloud.
The approach
A desktop suite that runs entirely on the CA's own PC — GSTR-1, 2B and 3B, an AI bill parser that reads client invoices, HSN/SAC typeahead, and byte-perfect exports into Tally, Miracle and Kuber. Machine-locked offline licensing (Ed25519).
