Why Seal can't charge renewals in India
Seal charges renewals automatically only on Shopify Payments, Stripe, PayPal Express and a few similar gateways. For a brand selling in India, it falls back to recurring invoices: every cycle, the customer gets an email with a checkout link and has to pay by hand. Every renewal waits on the customer.

How StackBack works in India
AutoPay on UPI and cards. The customer buys on StackBack's subscription checkout through your Razorpay account, paying for the first delivery and setting up AutoPay in one step. Every renewal after that is charged automatically, with a notice before each charge, and a failed charge is retried up to 3 times.
Prepaid and pay-as-you-go. These plans go into the cart like any product and check out on your Shopify checkout or any quick checkout, with your connected gateway.
Shopify-native. Every order and renewal lands in Shopify as a normal order, so inventory, shipping and reports keep working.
