Piroei review for GST Pro ‑ Invoices for India

We understand you are frustrated. We have sent you an email with our direct phone number and calendly link to book a call with us to resolve this issue. - We cannot pick taxes directly because Shopify does not provide an API for tax overrides - We have not "set up the percentage on their own in the app". I think you are referring to the default tax values under each product. The defaults should be updated with the exact tax amount you want. Hope you book a call with us to resolve this issue :)
