GST compliance for Shopify, solved.

It's a Shopify app that makes your store Indian-GST-compliant: it captures and validates GSTINs, computes the CGST/SGST/IGST split on every order, and generates GST Tax Invoices and Credit Notes as PDFs. It also produces GSTR-1 sectioned reports, a GSTR-3B summary, and GSTN-portal JSON for filing.

It's a port of our WHMCS and WooCommerce GST Manager plugins, rebuilt natively on Shopify's Remix/Polaris stack.

Yes. GST Manager works on every Shopify plan from Basic to Plus. GSTIN capture uses a cart-page Theme App Embed and order attributes rather than a Checkout UI Extension, so you don't need Shopify Plus and you don't need to touch checkout.

GST Manager treats your product prices as tax-inclusive and back-solves the GST out of them, so the invoice total always equals what the customer actually paid. For that to line up, Shopify itself must not add tax of its own. You set every region's rate to 0% and turn off the Global tax settings — the dashboard's Setup Health card detects this and links you straight to the right Shopify settings page.

To compute GST automatically, the app subscribes to order, fulfilment, and customer webhooks — and Shopify requires Protected Customer Data approval for those. You request it once in the Partner Dashboard. Until it's approved, the app still works through a "Generate now / Regenerate" button on the order page that produces invoices on demand without webhooks.

Orders are classified as B2B, B2CL, or B2CS based on the GSTIN and order value, which keeps your GSTR-1 sections clean. B2B Company orders (native Shopify B2B) get a Proforma first, then transition to a numbered Tax Invoice on the correct time-of-supply trigger. B2C orders skip the Proforma stage entirely. (B2B + Proforma is a Pro-tier feature.)

A full catalog: GSTR-1 sectioned exports (B2B, B2CL, B2CS, CDNR, CDNUR, B2CSA, HSN, DOCS), a GSTR-3B summary, and GSTN-portal JSON — all in the current GSTN format. Generation runs in the background and a History tab lets you re-download any past run. Reports are available from the Starter plan up.

On the legally correct time-of-supply trigger, which you choose: on first fulfilment (the default for goods, per GST §31), on payment (for services), or on order creation. For COD, the Tax Invoice issues at fulfilment and an RTO cancellation auto-generates a full-value credit note. You can also issue or regenerate any invoice manually from the order page.

The Free plan covers up to 50 orders/month and includes Tax Invoice + Credit Note PDFs (with a small "Powered by GST Manager" footer), cart-page GSTIN capture, custom invoice numbering, branding, all admin extensions, and the Customers list. GST report exports, bulk tools, and the customer-account download button start on the Starter plan.

Paid plans are billed in USD through Shopify Billing, so charges appear on your regular Shopify invoice. Every paid plan includes a 7-day free trial, granted once per store. The quota is order count per month with a hard cap (no surprise overage charges), and annual billing saves up to 45%. You can upgrade, downgrade, or cancel anytime — downgrading never deletes your existing data.
