- Payment Gateway Errors: Fixing Stripe, PayPal, Authorize.net, or Klarna API errors, holds, and rejections.
- Tax & Currency Glitches: Setting up automated sales tax rules (Shopify Tax, TaxCloud) and fixing multi-currency checkout bugs.
- Script Conflicts: Resolving broken tracking pixels and modern Checkout Extensibility migration errors.

FAQ
Why is my Shopify checkout or payment gateway failing?
Checkout failures usually happen due to expired API keys, rejected payment account verifications, broken tracking scripts, or outdated theme code. I run a full diagnostic audit to find the exact root cause and fix it fast.
Will fixing my checkout or payment gateway disrupt my live store?
No I work safely inside your backend settings or test theme duplicate. Your store remains live and fully accessible to visitors while I resolve the error.
How do you verify that the payment gateway fix actually works?
I place live developer test transactions directly on your checkout page to confirm that the payment routes successfully, confirmation emails trigger, and order statuses process before delivering your order.
