    My Shopify store is ready to launch, but PayPal still isn’t connected. I already hold a PayPal Business account; I simply haven’t begun the integration inside Shopify yet. I need you to: • Add PayPal as the primary payment processor, using the standard Shopify-PayPal flow (Express Checkout), enable test transactions, and confirm funds settle correctly. • Walk me through any settings that must be adjusted in PayPal or Shopify so refunds, multi-currency, and order status updates work automatically. Once PayPal is live and tested, I’ll move straight to phase two—fine-tuning shipping rules (zone rates, carrier-calculated options, or bespoke price tiers, depending on what you recommend). If you’re comfortable handling that as well, let me know so we can...

    I need PayPal fully integrated into my Shopify store so customers in Albania can pay however they prefer. At the moment I don’t even have a PayPal account, so the first step will be helping me open and verify a PayPal Business account that is eligible for Albanian merchants. Once the account is live, connect it to my Shopify Payments settings and make sure the following methods all work smoothly: • Credit/Debit Card Payments • PayPal Balance Payments • Bank Transfers Please handle the API credential generation inside PayPal, add them to Shopify, set up any required webhooks or IPN settings for order confirmation, and run a few real-world test transactions (sandbox first, then a small live purchase) to confirm the flow from checkout to payout. Deliverables will...

    I have a WIX site that is almost ready to launch. Before I publish, I need a specialist to run a final health-check on the build and wire up full PayPal checkout. Here is what I’m after: • Review the existing pages, store settings, and Wix dashboard to be sure nothing is mis-configured or missing. • Configure and verify PayPal as the live payment gateway, including sandbox tests so I can see a successful purchase flow from cart to confirmation email. • Flag any issues that could block transactions—tax rules, SSL, mobile display, or checkout wording—and suggest quick fixes. I’m not looking for shipping-setup help right now, and the catalog, cart, and inventory pieces are already in place, so the focus really is on PayPal connectivity and a t...

    My site is live but customers can’t complete credit / debit card payments. Everything else works, so the task is strictly about restoring that payment-processing functionality. I need you to pinpoint the root cause, apply the necessary code or configuration fix, and confirm that transactions go through from checkout to confirmation. To make expectations crystal-clear, here’s what I’d like back from you: • brief diagnosis summary outlining the fault you found • corrected code or settings applied (gateway keys, webhook, API call, etc.) • proof of at least one successful test charge in both sandbox and live mode Please be comfortable working directly on a production site—safeguarding existing data is essential—and be ready to start right ...

    I’m building an online directory where companies can publish a profile only after completing a paid registration. During sign-up the user enters both personal and company details, reviews the fee, and then checks out through their preferred method—credit or debit card, direct bank transfer, or Zelle. As soon as the payment clears, the profile goes live. Visitors anywhere in the world will be able to search the directory. Each listing should show public-facing information such as the company’s location, the services it offers, and client testimonials, while withholding any direct contact details unless the owner explicitly chooses to display them. The job covers: • A frictionless registration flow that captures the required information and locks progress until paym...

    My WordPress site, United Global Public, doesn't run any e-commerce at the moment. But it can be activated, a plug-in, I believe. I use PayPal for donations, but I haven't run any fundraising yet. The scope is straightforward: 1. Discovery & Requirements Review the existing website platform (WordPress, Wix, Squarespace, custom HTML, etc). Identify the e‑commerce plug‑in or platform (WooCommerce, Shopify Buy Button, Ecwid, BigCommerce plug‑in, etc). Confirm product types: physical, digital, services, subscriptions. Confirm payment methods needed (Stripe, PayPal, Apple Pay, etc). Confirm shipping rules, tax rules, and fulfillment workflow. Identify design requirements so the shop matches your brand. 2. Installation & Configuration Install the chosen e‑commerce plu...
