My WooCommerce store is almost ready to go live, but I still need a developer who can tie up the final loose ends—most importantly integrating a payment gateway that supports card-less EMI and plugging in three popular pay-later services: Snapmint, ZestMoney and LazyPay. Here is what I need you to handle from start to finish: • Recommend and configure the most suitable gateway for India that works seamlessly with cardless EMI options (Razorpay, PayU, Cashfree or any other you can justify). • Integrate Snapmint, ZestMoney and LazyPay through their respective APIs; I do not have merchant accounts yet, so you will also guide me through the onboarding and credential setup. • Build out multi-inventory logic so the catalog can track stock city-wise; product pages, checkout and admin should all reflect the correct availability. • Polish the remaining small tasks on the web app—minor UI tweaks, shipping rules by city, and any backend adjustments that surface during testing. Acceptance criteria 1. End-to-end test payments succeed for each EMI provider in both sandbox and live mode. 2. Gateway transactions appear in WooCommerce orders with proper status updates and refunds tested once. 3. Inventory deducts correctly per city, with an admin interface to add or edit stocks easily. 4. No console errors or broken layouts on mobile or desktop after your changes. The stack is WordPress + WooCommerce on a VPS (PHP 8.1, MySQL, nginx). I have SSH and cPanel access ready for you. Time is a factor, so please outline how many days you’ll need and any previous integrations you’ve done with similar pay-later services when you respond.
