I will fix shoplazza shopline checkout errors and failed payment gateway setup
Ethan carter
About this gig
Buyers reach your Shoplazza or SHOPLINE checkout, tap pay, and the card declines. They do not email you about it. They just leave, and you never learn why.
A checkout that quietly rejects good cards is the most expensive bug in ecommerce. You already paid for that traffic.
I diagnose and repair checkout and payment problems on Shoplazza and SHOPLINE.
WHAT I FIX
Declined or failed card payments and unclear gateway error codes
3D Secure set so it blocks fraud without scaring off small orders
Apple Pay and Google Pay that will not display or verify on mobile
Multi currency and multi country routing sending buyers to the wrong gateway
PayPal, Stripe, Airwallex, Payoneer and alternative payment method redirects
Cash on delivery rules, shipping tax conflicts and address validation errors
Mobile checkout friction and unnecessary form fields killing conversion
WHAT YOU GET
A test transaction from a real device, a written error log showing what failed and why, and a checkout that accepts money instead of politely refusing it.
Send me your store link and the error your customers see. I will diagnose it before you order.

I work on two platforms only: SHOPLINE and Shoplazza. That narrowness is deliberate.
Most freelancers list fifteen platforms and know one. I went the other way. When your Meta CAPI is double counting, your checkout is declining good cards, or your TikTok Shop stock is out of sync with your store, those are specific technical faults with specific causes, and guessing costs you a week.
I diagnose before I quote, I record proof of every fix, and I tell you when something is not worth doing.
Send me your store URL. I will tell you what is wrong before you spend anything.

FAQ
Apple Pay and Google Pay do not show on my checkout. Can you fix it?
Yes. That is nearly always domain verification, an unsupported gateway, or a theme conflict blocking the button. I fix the cause and confirm it on a live iOS and Android device.
Should I turn 3D Secure on or off?
Neither by default. I set it by order value, so high value orders get verification and small orders check out fast. That protects your dispute rate without taxing your conversion rate.
My customers say their card is declined but their card works elsewhere. Why?
Usually gateway routing, 3DS misconfiguration, or a currency and country mismatch on the card channel. I read the actual decline codes rather than guessing, then correct the routing rules.
Which payment providers can you configure?
Shoplazza Payments, SHOPLINE Payments, PayPal, Stripe, Airwallex, 2Checkout, Payoneer, Klarna and most alternative payment methods, plus regional gateways and cash on delivery in supported markets.
Can you help if Shoplazza Payments has restricted my store?
I can prepare and organise your appeal documentation and correct the underlying issues, such as dispute rate and fulfilment delays. I cannot guarantee any platform decision, and I will never claim otherwise.
Will you test with a real order?
Yes. I run a live low value transaction on desktop and mobile, then refund it. You get the screen recording so you can see exactly what your buyer sees.
Do you fix abandoned checkout issues too?
Yes, on Standard and Premium. I remove unnecessary fields, fix mobile layout breaks, enable express checkout, and set up abandoned cart recovery inside your platform.
