Product walkthrough

From invoice upload to ARN — in five steps

Step 01 · Invoice intake

Upload invoices in the format you already use

Drag PDFs, phone photos, or Excel exports into File Mitra. Each invoice is queued for extraction — no portal login, no manual re-entry into spreadsheets.

Step 02 · AI validation

Every invoice is read, matched, and flagged for review

GSTIN, HSN codes, taxable value, and ITC eligibility are extracted and cross-checked. Issues surface before they reach your return — you approve corrections, not surprises.

Step 03 · Return preparation

GSTR-1 and GSTR-3B built from your reconciled ledger

Outward supplies roll into GSTR-1. Tax liability and ITC flow into GSTR-3B. Both returns stay linked to the same invoice ledger you uploaded.

Step 04 · Human approval

Nothing files until you explicitly approve

Review net payable, confirm return details, then authorize filing. When GSTN requests captcha or OTP, the handoff happens in File Mitra — you complete verification, we continue the session.

Captcha prompts follow the same handoff — you verify, File Mitra continues the session.

Step 05 · Filed & recorded

ARN captured and stored in your filing history

Every successful filing saves the acknowledgement reference, timestamp, and return type. Past periods stay searchable for audits, reconciliations, and client reporting.

The problem

GST filing shouldn't consume your month

01

Monthly deadline pressure

GST due dates pile up while you juggle invoices, clients, and the GSTN portal — one missed step means penalties.

02

Portal friction at every step

Captcha, OTP, session timeouts, and form errors turn a routine filing into an hour-long ordeal.

03

Spreadsheet chaos

Invoices, PDFs, and portal screens never stay in sync — reconciliation eats your evening.

You stay in control

Guided automation with human checkpoints

File Mitra is built for business owners who need compliance help — not black-box portal access.

01

You approve every filing

Returns are not submitted without your explicit confirmation in the dashboard.

02

Captcha and OTP stay with you

When GSTN requests verification, you complete it in File Mitra — not unattended access.

03

Encrypted credentials and audit trail

GSTN credentials are encrypted. Every action is logged in your filing history.

Features

Focused tools for monthly GST compliance

Everything you need for monthly GSTR-1 and GSTR-3B — without portal juggling.

GSTR-1 preparation

Invoice-led return preparation with review before filing.

GSTR-3B filing

Guided GSTR-3B workflow with portal-aware automation and live status.

AI-assisted invoice processing

HSN codes, tax values, and party details extracted for your approval.

ARN tracking and filing history

Acknowledgement references and past filings kept in one audit-friendly view.

Trust & security

Built for credential-sensitive workflows

  • 01

    Encrypted credential storage

    GSTN credentials encrypted with AES-256 — never stored in plain text.

  • 02

    User-approved filing

    Guided automation stops at your approval gate before any return is filed.

  • 03

    Complete audit trail

    Login, handoff, preparation, and filing events logged in your dashboard.

Clear boundaries

What File Mitra does not do

Honest automation for compliance — not overpromised magic.

  • File returns without your explicit approval
  • Auto-submit captcha or OTP
  • Replace your accountant or tax advisor
  • Guarantee filing outcomes, zero notices, or tax savings
