FAQ ​

Quick answers to the questions merchants ask most about GST Manager for Shopify.

Does this replace Shopify's built-in tax? ​

Yes — for GST. GST Manager computes the CGST/SGST/IGST split and issues the tax invoice, so Shopify should charge 0% tax. Prices are treated as GST-inclusive and the tax is back-solved out of them, so the invoice total always equals what the customer paid. See Configure Shopify taxes.

How does it decide CGST/SGST vs IGST? ​

By comparing your registered state (from your GSTIN) with the order's place of supply: same state → CGST + SGST (half each); different state → IGST.

Where do product GST rates come from? ​

From a per-product HSN/SAC + GST rate you set under Products → Import HSN codes or the per-product HSN block. If a product has no rate, GST Manager uses your Default GST rate (typically 18%). A slab rule is available for clothing/footwear.

How do customers give their GSTIN? ​

Through the cart-page "Get GST Invoice" block (a Theme App Embed), from Shopify's native B2B Company tax ID, from their customer record, or by admin override. You control cart capture under Settings → Other Settings.

When is the tax invoice issued? ​

Immediately for regular orders. B2B Company orders get a Proforma first, and their Tax Invoice is issued when the order is fulfilled or paid — whichever happens first — matching the legal time-of-supply trigger.

Can I edit an order after the invoice is issued? ​

The invoice can freeze a party snapshot at issuance (Pro's "Lock invoice contents"), so later edits in Shopify don't drift into an already-issued document. The deliberate correction path is the order's Regenerate action, which refreshes the buyer block while keeping the same invoice number and date.

What GST reports can I export? ​

GSTR-1 (Full / B2B / B2C), GSTR-3B summary, offline-tool CSVs (B2B, B2C small, B2CSA amendments), an HSN-wise B2B summary, and a GSTN-portal JSON. Reports run in the background with a History tab for re-downloads. Reports need the Starter plan or higher. See Reports.

What is "Protected Customer Data" and do I have to do anything? ​

It's Shopify's platform rule for apps that read order/customer data. You approve it once in your Partner Dashboard so order webhooks are delivered. Until then, use Generate now on each order. See Data & privacy.

How much does it cost? ​

There's a Free plan (up to 50 orders/month) and paid Starter / Pro / Scale plans, each with a 7-day free trial. Billing runs through Shopify and appears on your Shopify invoice. See Billing.

Do I lose my invoices if I uninstall? ​

The GST data written to your orders/products stays on your store as metafields. Download offline copies (Reports → Bulk download) before uninstalling if you want them outside Shopify. See Uninstalling.

Is my data safe? ​

GST Manager reads only the data needed to produce invoices, over HTTPS, and implements Shopify's mandatory data-deletion webhooks. See Data & privacy.
