Shopify payments on hold means the payment provider paused payouts or new charges. The theme did not do that. The admin banner and the email from Shopify Payments say what they need. A developer cannot click a secret button and release the money.
Read the payout or payments notice in Shopify admin and complete the identity or bank steps it lists. Reply in that thread. Separately, stop the store problems that create refunds: overselling, unclear shipping, and checkout errors.
What a developer can fix while you wait
- Checkout errors that create failed orders and angry buyers. See checkout drop-off
- Stock that sells units you cannot ship. See inventory that does not match
- Order mail that never arrives, so people dispute the charge. See order emails
- A second gateway for a country where Shopify Payments is unavailable
Gateway setup for India is separate from a US or Australian Shopify Payments account. Currency display is Markets showing the wrong currency. Store work around those payments is Shopify development and, after launch, monthly maintenance.
We will not promise to lift a hold. We can fix the storefront issues around it. Send the store URL.
