Native desktop, direct integration
Real Windows and macOS apps — not a browser tab — that sync two-way with Tally and file straight to the GST portal. That's the unfair advantage behind every reconciliation, return and notice.
Built for your machine, not a tab
One full compliance suite, compiled for Windows and Apple silicon — fast on huge datasets, offline-capable, and quietly kept up to date.

Plugged into the two systems Indian GST actually runs on
No brittle CSV round-trips. GST365 talks to Tally and the government portal directly, so your books, returns and filings stay in lockstep.
Tally
Accounting sync
Keep Tally for your books and add intelligence on top. GST365 syncs vouchers and ledgers both ways — reconcile, file and answer notices without leaving your workflow.
- Two-way sync of sales, purchase & ledger data
- Push reconciled returns back to Tally
- Works across the huge TallyPrime install base
- No manual export/import between books and portal
GST Portal (GSTN)
Direct filing
A native GSP/ASP connection to the government portal. Pull GSTR-2B and IMS data, prepare returns, and file GSTR-1, 3B and 9/9C with a single click.
- One-click GSTR-1, 3B, 9 & 9C filing
- Live GSTR-2B & IMS invoice pulls
- e-Invoice IRN + QR via the IRP
- e-way bill generation and tracking
Engineered for the way GST actually works
Local-first performance, GSTN-scale matching, always-current rules and privacy that stays on your machine.
Local-first & offline-capable
Reconcile and draft even when the portal is slow or you're offline. Your data stays on your machine until you choose to sync.
Built for GSTN scale
Match tens of thousands of invoices in seconds — engineered for the same volumes the GST network handles every day.
Always up to date
Rates, rules and forms update automatically — including GST 2.0's two-slab structure — so your logic never goes stale.
Private by design
Encryption at rest, granular permissions, and a full audit trail. Your financial data is never used to train third-party models.
Works with your stack
From TallyPrime and the GST portal to SAP, Zoho, Busy and plain Excel — GST365 slots into the tools your team already lives in.
