Internal Landed Cost Calculator

@AwaisChaudhry

Hello, I’m Muhammad Awais. I’ll deliver a fast, login-protected web app where staff drag-and-drop an Excel file and instantly receive the same sheet enriched with DHL and FedEx data, while preserving the original formatting and formulas. Tech approach: a React frontend with a Node.js/Express API and Python services for Excel processing. The flow is straightforward: sign-in, upload, read each row, call DHL and FedEx APIs to list available services for that origin-destination, and append per-service columns for fully-loaded landed cost (freight + duties) and expected transit time. If a dimension is blank, I’ll fill a sensible default. If receiver details are incomplete, I’ll auto-complete the address so calls aren’t rejected. After all rows finish, the app streams back the original file with the new columns on the right, no extra steps for staff. I’ll aim for a working version quickly with core flow and secure auth, then iterate to add more carriers and UI polish. The plan aligns with your requirements: Python, Data Processing, Web App, Node.js, API Integration, Excel, React.js and JavaScript. Can you confirm API access for DHL and FedEx (keys, sandbox vs prod), and if there are any other carriers to include?\n\nDo you have an Excel template (headers, data types), and how should missing or malformed rows be treated?\n\nWhat security/compliance needs apply to login, data storage, and processing of shipment data?\n\nWhich deployment target and environment (cloud provider, sta

The original formatting and formulas will stay untouched, with new columns added neatly at the end. My focus will be speed, reliability, and keeping the whole flow simple so the file goes in and comes back out without any extra steps. Looking forward to discussing further. Regards, Kamran.

@faisal9263

Hello, I understand you need a secure, fast web app that enriches Excel shipment files using live DHL and FedEx API data—while preserving formatting, formulas, and minimizing manual effort. I’m experienced in building login-protected web apps, integrating carrier APIs (DHL/FedEx), handling Excel (.xlsx) files safely, and optimizing for speed and accuracy. My approach: I’ll build a secure upload interface → parse each row → auto-fill missing dimensions/addresses → query all carrier accounts for valid services → calculate landed cost and transit time → write new columns without altering existing formatting → enable one-click download. I prioritize accuracy, reliability, and rapid delivery. Let’s connect and get a working version live quickly.

@TheSecondSource

Hey! We can build a secure, login-protected web app that processes your shipment Excel files and enriches them with live DHL and FedEx logistics data automatically. We’re a team of 62 professionals with over 9 years of experience in full-stack web development, API integration, and automated spreadsheet processing. Here's how we can help: * Implement a user authentication system so only authorized staff can access the app * Enable drag-and-drop upload of Excel (.xlsx) files with multi-item shipment lines * Process each row by calling your DHL and FedEx APIs to fetch available services, landed costs, and estimated transit times * Auto-fill missing dimensions with defaults and complete incomplete receiver addresses to prevent API rejections * Append the enriched data as new columns on the right while preserving all original formatting and formulas * Provide a one-click download of the processed spreadsheet for immediate use A few clarifying questions: do you want this hosted internally, or on a cloud platform for remote access? Are there any API rate limits we need to account for, or should we batch requests to optimize speed? Do you have preferences for tech stack—Python backend with Node/React frontend, or a fully JavaScript/Node.js solution?

@yuliussmayoru

Hello! I’ll build a simple login protected web app: upload your .xlsx -> I call your 2 DHL, 4 FedEx accounts per row -> return the same file with new columns appended (landed cost, transit time per available service). My approach: I keep your workbook untouched (formats and formulas stay the same) and only write results into added columns on the far right. Before rate calls, I normalize rows, fill missing dimensions with your defaults, and autocomplete incomplete addresses so carrier APIs don’t reject. Calls run in controlled parallel with retries, rate-limit handling, and clear per-row error logs. Tech stack: FastAPI or Node, TypeScript (whichever you prefer), a small cache, log store for speed and auditability. To start, I need a sample XLSX, your default dimension rules, duty, tax rules, and DHL, FedEx API credentials. Warm regards, Yulius Mayoru

@Ussama91

I propose a Python-based web application using Flask or Django, leveraging pandas for Excel file manipulation and the requests library for API calls to DHL and FedEx, with a simple login system and a user-friendly drag-and-drop interface, adapting to the proposed budget and delivering a working version quickly. Waiting for your response in chat! Best Regards.

@MSaadJaved

Hi Mark L., I can build the login-protected web app you described. Staff will drag-and-drop an .xlsx, the app will read each line, call your DHL and FedEx accounts, list every available service for the route, and write landed cost and transit time into new columns. Blank dimensions will get defaults and incomplete receiver data will be auto-completed so carrier calls do not fail. The original formatting and formulas will be preserved. I am a full‑stack developer with experience in carrier API integration and spreadsheet automation. I use proven tools that speed delivery, such as Node.js/Express and SheetJS for safe .xlsx read/write, secure auth, and server-side caching to avoid repeat calls. Please see my profile and portfolio for similar work. Do you plan to provide the carrier credentials and an address-autocomplete source? Best regards, Saad J.
