GSTR-1 filing, generated from your marketplace exports.
Upload the Excel files you already download — Amazon MTR, Flipkart settlement, Meesho TCS, E-Invoice — and GST Filing turns them into GSTN-ready GSTR-1 files. No APIs to connect, no manual re-typing, no spreadsheet gymnastics.
Everything GST Filing does
From raw marketplace downloads to portal-ready files — with every check run before the GSTN sees anything.
Marketplace Excel in
Amazon MTR, Flipkart settlement, Meesho TCS and E-Invoice exports — the files every seller already downloads. Zero API onboarding.
GSTN-ready output
7 GSTN-compliant CSVs plus a ready-to-upload gstr1.json — generated per company, per month, organised automatically.
14 states covered
State-wise splits handled for multi-state sellers — the exact scenario where manual GSTR-1 prep falls apart.
155 validation checks
Mismatches, gaps and duplicates get caught before filing — including E-Invoice vs marketplace dedup — not after a GSTN rejection.
Audit vs previous month
Every run is compared against your previous filing so unusual swings stand out before you submit.
Multi-company built in
Manage multiple companies and GSTINs from one login with a company switcher — each with its own outputs and settings.
How it works
From download folder to filed return — four steps, once a month.
Download exports
Grab your monthly Excel reports from each marketplace, as you already do.
Upload to GST Filing
Drop the files in — the tool detects the format per marketplace.
Validate & review
155 checks run, E-Invoices dedupe, and the month is compared to your last filing.
File on GSTN
Download the 7 CSVs or gstr1.json and upload straight to the portal.
