I need a ready-to-install Shopify app or custom plugin that lets my customers see real-time shipping costs while they browse. The two core functions I must have are rate comparison across my predefined shipping options and clear delivery-time estimates next to every rate. Costs should be calculated strictly on a weight-based formula that I will supply. Because I am still evaluating carriers, the code should be flexible enough to accept additional APIs later; at launch it can pull data from any single carrier you already support. A clean settings panel inside the Shopify admin is important so that my team can adjust weight brackets and handling fees without touching code. Before we get started, please provide a live demo or staging-store link that shows the calculator in action inside the cart or checkout so I can verify speed and UX. Deliverables • Packaged Shopify app or installable custom plugin • Quick-start documentation covering setup, weight table editing, and carrier/API switching • Short loom or screen-share walkthrough of the live demo/store I’m ready to move quickly once I see a working example that matches the requirements.

Hello! I’d be glad to deliver a ready-to-install Shopify app (or custom plugin) that shows customers real-time, weight-based shipping costs while they browse, with clear delivery-time estimates and a smooth cart/checkout experience. Proposed Approach 1. Core Shipping Logic • Weight-based rate calculation using your provided formula • Side-by-side comparison of predefined shipping options • Delivery-time estimates displayed next to each rate 2. Carrier & API Flexibility • Initial integration with a supported carrier • Modular architecture so additional carrier APIs can be added later without refactoring • Clear abstraction layer for rate and ETA logic 3. Shopify Admin Settings Panel • Editable weight brackets and handling fees • Toggle shipping options on/off • No-code configuration for your team 4. Frontend Integration • Rates shown in cart and/or checkout (Shopify-compliant) • Fast response times and clean UX • Fully compatible with Shopify Online Store 2.0 Deliverables • Packaged Shopify app or installable custom plugin • Live demo / staging store showing the calculator in action • Quick-start documentation + short Loom walkthrough I’ve built Shopify shipping and pricing extensions before and can share a demo store immediately so you can verify speed and UX before we proceed. Let’s review the demo and move fast from there. Best regards, Jasmin

Hi there, I understand you want a ready-to-install Shopify app or a custom plugin for Woocommerce that shows real-time shipping costs in the cart, with rate comparison across predefined options and delivery-time estimates next to each rate. The code must be weight-based (your formula), flexible enough to plug in additional carrier APIs later, and include a clean settings panel in the Shopify admin for weight brackets and handling fees without touching code. I’ll deliver a packaged app or plugin, quick-start docs for setup and editing weight tables, a carrier/API switch, and a short Loom walkthrough of a live demo. The solution will be modular and well-documented so your team can swap in new carriers via configuration rather than code changes. What is the single most critical metric you want to optimize with this shipping calculator (speed, accuracy, or UX) and do you have a preferred data format for your weight table (CSV, JSON, or Admin UI only)? What you get: - A ready-to-install Shopify app or WooCommerce plugin with a weight-based shipping calculator, live rates, and ETA estimates. - A settings panel for weight brackets, handling fees, and carrier API switching. - Quick-start docs and a short loom walkthrough showing the live demo/store. - A lightweight structure that makes adding new carriers or APIs straightforward later. What is the single most critical metric you want to optimize with this shipping calculator (speed, accuracy, or UX) and do you have a preferred dat

Hi, I can build a ready-to-install Shopify app that shows real-time, weight-based shipping costs directly in the cart with clear delivery-time estimates. I’ve previously implemented custom shipping calculators and carrier integrations for Shopify stores, including dynamic rate comparison and admin-editable weight tables. I can share a staging demo that shows rates updating instantly in the cart so you can review speed and UX before we proceed. The app will calculate rates using your weight formula, display multiple predefined options with delivery timelines, and include a clean admin settings panel where your team can adjust brackets, handling fees, and carrier rules without code. The architecture will be modular so new carrier APIs can be added later with minimal changes. Deliverables include a packaged Shopify app/plugin, install instructions, documentation for editing weight tables and switching carriers, plus a short walkthrough video of the live demo. The solution will be optimized for performance, mobile responsiveness, and Shopify checkout compatibility. Once you review the demo and confirm the logic, I can finalize and deploy quickly.
