What it does

Your CA, without the back-and-forth

Give your accountant a read-only link to your reports, or have the monthly filing pack emailed to them automatically on a day you choose. No Shopify account needed on their side.

GSTR-1, GSTR-3B and IFF

Filing-ready JSON for whichever scheme you're on. On QRMP, the app knows the first two months of each quarter are furnished as IFF and warns you if you reach for the wrong file.

Rule 48 and Rule 55 done properly

Invoices print marked Original / Duplicate / Triplicate as the rules require, in one job or one at a time. Moving goods without a sale — an exchange, a stock transfer, items to a job worker — issues a delivery challan in its own series.

HSN codes without the typing

Pulls HS codes straight from your Shopify products, applies one code across a whole catalogue in a click, and warns you before you file if any line is still missing one.

Already been selling?

Backfill invoices for past orders from any start date, and pick up your existing numbering exactly where your old system left off.

Automatic GST invoices

Every order generates a proper Tax Invoice or Bill of Supply automatically — CGST+SGST for same-state, IGST for inter-state, worked out per order.

Credit & debit notes

Cancellations and refunds raise credit notes automatically. Price corrections and extra charges get a manual debit note in a couple of clicks.

GSTR-1 / GSTR-3B exports

Download filing-ready JSON for your return period, built directly from your own invoices — no manual reconciliation.

Your numbering, your way

Define your own invoice/credit note/debit note number format. Migrating from another app? Continue exactly where you left off.

Reports, on demand

Export invoices, credit notes, and debit notes as CSV, PDF, or Excel for any date range, or email them straight to your accountant.

Choose how it looks

Three PDF layouts to pick from, your logo and signature hosted on Shopify's own CDN, and a brand-color accent option.

Pricing

Free right now — every feature, no order limits. No trial to expire and no card to enter.

A $9.99/month plan is available from inside the app if you'd like to support it. It unlocks nothing extra today; paid plans will only ever gate features added later, never take away what you already use.
