A chartered accountancy firm with 200+ clients was spending enormous time on monthly GST return filing. Each filing required exporting data from Tally, reconciling with purchase registers, preparing returns in the correct format, and filing on the GST portal. We automated the entire pipeline from Tally export to portal submission.

Filing GST returns for 200+ clients each month required 10+ CA staff working overtime during filing periods. Data extraction from Tally was manual, reconciliation was error-prone, and the GST portal's slow interface made each filing take 20-30 minutes. Late filing penalties were a constant risk, and client satisfaction was declining.
We built an end-to-end automation pipeline that connects to Tally via its API, extracts and validates transaction data, prepares GSTR-1 and GSTR-3B returns, auto-fills the GST portal forms, and generates filing confirmation reports. The system handles the complete workflow including 2FA authentication and digital signature integration.

All credentials are stored using AES-256 encryption. The automation runs on the firm's own servers, and credentials never leave their infrastructure. Each access is logged for audit purposes.
Yes, the system can be extended to handle GSTR-9 and GSTR-9C annual returns. This was added as a Phase 2 enhancement for this client.
