FAQ
Why is my Shopify checkout not working or payments not going through?
Shopify checkout not working usually comes from payment gateway errors, test mode left on, app or theme conflicts, or currency mismatch. I diagnose the exact cause behind Stripe, PayPal, or Shopify Payments failures and fix it so customers can complete checkout again.
Can you fix Stripe and PayPal payment gateway errors on Shopify?
Yes. I fix Stripe and PayPal gateway errors on Shopify, including failed payments, checkout errors, sandbox and live connection issues, webhook failures, and payment method not showing. I also integrate and setup new Stripe or PayPal accounts if needed. Region specific gateways included.
Why is Klarna, Afterpay, or Affirm not showing at checkout?
Klarna, Afterpay, or Affirm often disappear at checkout due to currency mismatch, unmet cart minimums, country eligibility rules, or theme and script conflicts. I check the eligibility logic and fix the setup so your buy now pay later option reappears at checkout.
Can you fix declined payments and do not honor errors?
Yes. I resolve declined payments, do not honor errors, and false declines caused by fraud filters, 3D secure verification, or bank issuing rules. I also fix chargebacks related settings and test mode issues so real customers stop getting blocked at checkout.
Do you integrate new payment gateways like Paystack, Flutterwave, or Razorpay?
Yes. I integrate and set up Paystack, Flutterwave, Razorpay, and other regional payment gateways for Shopify, alongside Stripe, PayPal, and Klarna. Every integration is tested on sandbox and live mode before delivery so payments process correctly. COD and bank transfer setup available.
Can you fix PayPal button not showing or not working?
Yes. I fix PayPal button not showing, not loading, or not working at checkout, along with Express Checkout errors and redirect failures. I test the fix live so your customers can complete payment through PayPal without interruption. Standard and Express PayPal issues covered.
Can you fix Shopify Scripts to Functions migration issues affecting checkout?
Yes. If Shopify Scripts stopped working after migration, I rebuild your payment rules and checkout logic using Shopify Functions, GraphQL, and Liquid code so discounts, payment gating, and checkout extensibility keep working as before. Deprecated Scripts editor issues fixed too.
Do you fix mobile checkout issues and cart abandonment caused by payment errors?
Yes. Payment errors, slow gateway response, and confusing checkout steps are major causes of mobile checkout issues and cart abandonment. I fix mobile checkout bugs, express wallet setup, and payment flow so more mobile visitors complete their order. This lowers cart abandonment fast.
Can you integrate crypto payments like Bitcoin or USDT into my Shopify store?
Yes. I integrate Shopify supported crypto gateways like Coinbase Commerce and BitPay so you can accept Bitcoin, Ethereum, and other cryptocurrencies at checkout. Note Shopify only allows officially approved crypto providers, not custom APIs, at native checkout.
Can you fix credit card declined or invalid card errors at checkout?
Yes. I fix credit card declined, invalid card number, expired card, and CVV mismatch errors, plus 3D secure verification failures. I also check for issuing bank blocks, fraud filter false declines, and gateway settings causing genuine cards to fail at checkout.
