Checked as they type
Format, state code and the check digit are verified before the order is placed, so a typo never reaches your invoice.
Shopify app for Indian sellers
Collect your buyers’ GSTIN. On every Shopify plan.
Basic plan stores can’t add fields to checkout. GST Capture adds a GSTIN field to your cart, checks it as the buyer types, and saves it on the order so the invoice is right the first time.

Everything a B2B order needs, without Shopify Plus
Your business buyers want input tax credit. You want clean invoices and a GSTR-1 that files without edits.
Cart page and cart drawer
One switch in the theme editor. The field sits above the checkout button and picks up your theme's fonts.
After checkout too
Buyers who used Buy now can add their GSTIN on the Thank you or order status page, right up until you ship.
On the order, tagged
GSTIN, business name and state appear on the order page, and every B2B order gets a GST B2B tag you can filter by.
GSTR-1 ready export
Download B2B table 4A as CSV, with place of supply and taxable value split by tax rate. Hand it straight to your CA.
IGST or CGST + SGST
The widget compares the buyer's state with yours and shows which tax applies, so nobody is surprised by the invoice.
Live in three steps
No theme code to edit. The app’s home page walks you through each step with direct links.

Questions
Does it work on the Basic plan?
Yes. Shopify only lets Plus stores add fields inside checkout. GST Capture uses the cart, the Thank you page and the order status page, which every plan except Starter can customise.
Is the GSTIN checked with the GST portal?
It checks the format, the state code and the check digit, which catches almost every typo. It does not look up the business name on the GST portal, because that needs a paid GST service provider.
Does it create GST invoices?
No. It puts the GSTIN, business name and state on the order as additional details, where your invoice app or order printer template can read them.
Where is the data kept?
In your Shopify store, on the order and the customer. Our server only holds a GSTIN for a few minutes if a buyer adds it before Shopify finishes creating the order.
