About this gig

Customers reaching checkout but not paying? A broken payment gateway quietly kills sales. I find the cause and fix it so orders go through again.

As a Shopify developer, I troubleshoot payment failures, declined transactions, checkout glitches, cart bugs, and gateway conflicts. I work with Shopify Payments, Stripe, PayPal, Klarna, and other processors, including webhook and API connections that stopped syncing.

I can also handle custom checkout code in Liquid, cookie consent and GDPR setup, high-risk payment processor integration, and Whop checkout connections when your business needs them.

What you get:

Root cause diagnosis

Clean, tested fix on a duplicate theme first

Test orders to confirm payments work

Mobile and desktop checkout check

Simple notes on what was changed

Your live store stays safe throughout, and I never need your payment credentials or bank details. Message me with a short description or screenshot of the error before ordering, and Ill confirm the best package.
