Compliance Is a Cycle, Not a Filing

Every stage in one place, each one informing the next

icons
1. Reconcile Before You File

Match GSTR-2A and GSTR-2B against your purchase register and GSTR-1 against GSTR-3B. Mismatches are cheaper to fix before a return goes in than after.

icons
2. File the Return

GSTR-1, GSTR-3B and GSTR-9 filed from the same dashboard the reconciliation ran in, with no platform fee for the filing itself.

icons
3. Pay and Track Challans

Create challans for tax, interest, late fees and penalties, and keep every challan since July 2017 in one searchable place.

icons
4. Answer Notices

Notices fetched from the portal automatically and tied back to the reconciliation that explains them, then tracked through to closure.

Why Teams Move Their Compliance Here

icons
Deadlines Per Client, Per Return

Due dates tracked across every GSTIN you handle, so an approaching deadline is visible rather than remembered.

icons
Audit-Ready by Default

Filings, reconciliations, challans and notice responses stay linked, so the working behind any number is still there when someone asks.

icons
20+ Reconciliation Reports

Including e-invoice against sales register and annual GSTR-9 workings — the checks that catch what a filing-only tool never looks at.
