GST InvoiceIndia Pro
Turn Shopify orders into tax invoices, bills of supply and credit notes with CGST, SGST and IGST calculated automatically, then export GSTR-ready reports your accountant can file from.
By Wyron Technologies
GST-compliant invoices for Shopify stores in India.
Built for the way GST actually works: place of supply, HSN and SAC rates, gap-free numbering, credit notes, SEZ and export supplies, and the reports your accountant asks for on the 11th and 20th of every month.
Everything GST asks of an invoice, nothing you have to remember
Every GST document
Tax invoices, bills of supply, credit notes and debit notes generated from any Shopify order, one at a time or in bulk.
Tax worked out for you
Place of supply is detected from the shipping address, then CGST and SGST/UTGST or IGST are applied from the HSN or SAC code on each product.
Gap-free numbering
A sequential series for each financial year, document type and GSTIN location, with your own prefix, suffix and padding. Cancelled documents keep their number.
Multiple GSTINs
Map each Shopify location to its own GSTIN, address and number series. Orders are invoiced under the GSTIN of the location that fulfils them.
SEZ, exports and composition
Zero-rated SEZ and export supplies under LUT, reverse charge, and bills of supply for composition-scheme dealers.
Templates that look like you
25 ready-made designs across seven layouts, with your logo, colours, bank details, terms and signatory. Or paste your own invoice HTML.
Email from your own address
Connect your SMTP server and send invoices with the PDF attached, automatically when a document is generated, an order is paid or fulfilled.
Credit notes for refunds
Issue a credit note against the original invoice for any refund, by hand or automatically, with exactly one note per Shopify refund.
GSTR-ready reports
GSTR-1 tables for B2B, B2C, CDNR, CDNUR, exports and SEZ, GSTR-3B supply summary, HSN summary and a GSTR-9 yearly view, all exported as CSV.
Purchases and input tax credit
Record inward supplies and expenses with ITC eligibility, so eligible credit flows into your GSTR-3B figures.
E-invoice ready
Prepare the INV-01 e-invoice payload, IRN hash and QR code for B2B documents, following the GSTN schema.
Audit trail built in
Every generation, cancellation, email and settings change is logged. Supplier details are frozen on each document so reprints match the original.
Set up once, invoice forever
Add your GST identity
Enter your legal name, GSTIN, address and bank details in Settings. The app validates the GSTIN and detects your state code.
Map products to HSN and rates
Set the HSN or SAC code and GST rate for your products, or keep a store-wide default. Add extra GSTIN locations if you ship from more than one state.
Generate, send, report
Pick orders in Generate Invoices or let the app issue documents automatically. Download PDFs, email them, and export GSTR reports at month end.
Read-only access, by design
The app reads
- Orders: line items, prices, taxes, discounts, payment and fulfilment status, refunds
- Customers on those orders: name, email, billing and shipping address
- Products and variants, for HSN and GST rate mapping
- Locations, for multi-GSTIN invoicing
The app writes
- Your invoice logo, saved to your own Shopify Files. Nothing else in your store is modified.
Full details of what we store, where, for how long and how to have it deleted are in the privacy policy.
Questions merchants ask us
Who is GST Invoice India Pro for?+
Shopify merchants registered under GST in India, whether regular or composition scheme, selling B2B, B2C or both. The app runs inside the Shopify admin and works with any sales channel.
Does the app change my Shopify orders or tax settings?+
No. It reads orders, products, customers and locations to build documents, and never edits them. The only thing it writes to your store is the logo you upload, which is saved to your own Shopify Files.
Does it need the Online Store channel or Shopify POS?+
No. The app is an embedded admin app and does not install theme code. It works for stores selling through any channel.
Are e-invoices registered with the Invoice Registration Portal?+
The app prepares the GSTN INV-01 payload, computes the IRN hash and generates the QR code for B2B documents. Direct submission to an IRP is being added; until then, use the payload with your IRP or GSP.
Can I use my own invoice design?+
Yes. Choose from 25 presets and customise the logo, colours, fields, terms and signatory, or switch to your own HTML template for full control.
Where is my data stored, and who can see it?+
Store and invoice data is held on Google Cloud in Mumbai and a managed PostgreSQL database, encrypted in transit. SMTP passwords are encrypted at rest. We never sell data or use it for advertising. See the privacy policy for the full detail.
What happens when I uninstall?+
Access tokens, SMTP credentials and automations are removed immediately. Forty-eight hours later, Shopify instructs us to erase everything else, including invoices. GST law requires you to keep tax records for 72 months, so export your documents and reports before uninstalling.
