Drone Quote Calculator Web App

@Microlent

This is a straightforward project and I can build a clean, lightweight quote management application that uses Google Sheets as the database while remaining easy to maintain and deploy. The solution will include: ✓ Google OAuth authentication ✓ Email whitelist access control ✓ Live item/pricing data from your existing Google Sheet ✓ Quantity-based calculations with support for future pricing formulas ✓ Quote creation and editing ✓ Automatic write-back to a separate Quotes-Archive sheet ✓ Quote history and reopen/resave functionality ✓ Mobile-friendly responsive interface ✓ Clear deployment documentation Recommended Stack: ✓ React + Google Sheets API ✓ Firebase Authentication (Google OAuth) ✓ Firebase Hosting or Vercel ✓ Google Apps Script or lightweight Node.js backend Deliverables: ✓ Complete source code ✓ Google Sheets integration ✓ OAuth setup ✓ Deployment guide ✓ User documentation The architecture will keep your pricing sheet read-only while maintaining a structured quote archive for tracking and reporting. One question: Would you like quote PDFs (print/download/email) generated as well, or is saving and reopening quotes in Google Sheets sufficient for your workflow? Best regards, Microlent Team

Hi there, We understand you need a lightweight web app for creating spray-job quotes without using spreadsheets, utilizing Google Sheets for data storage and authentication through Google OAuth for secure access. Our team at Webbook Studio has experience with similar projects, such as building custom web applications using JavaScript, Node.js, and Vue.js, and integrating Google APIs for seamless data operations. For example, we developed a learning platform website for children using PHP, WordPress, and custom design, which involved reading and writing data to a database. We can deliver a user-friendly interface for quote calculation, with real-time price updates from your Google Sheet, and accurate archiving of quotes in a separate sheet. One question: Are there any specific UI/UX requirements or preferences you have for the web app, such as a particular color scheme or layout? Feel free to message us to discuss the details! — Webbook Studio

Hi — Elias here from Miami. I see you're looking for a web app to create spray-job quotes for your uncle and yourself. This sounds straightforward, but I understand the challenge lies in keeping it user-friendly while handling the calculations accurately. One common issue with similar projects is ensuring the calculations are correct, especially if you have multiple variables to consider. Another potential pitfall is making sure the interface is intuitive so you can both use it without stress. My approach would be to start with a simple layout, allowing you to input necessary details easily. I’d use PHP and JavaScript to handle the backend calculations while keeping the front end clean with Vue.js. This way, we can ensure the application is responsive and quick. I'd love to know what specific features you want in the quotes, and if you have any examples of similar tools you like. Let’s make this a tool that works seamlessly for you. Looking forward to your thoughts.

@n2rtechnologies

Hi there, I got it. This is not a large CRM or ERP system — it’s a lightweight internal quote generator that replaces your spreadsheet workflow and keeps everything simple for daily use between two people. What I feel the cleanest approach here is to keep Google Sheets as the single source of truth, use Google OAuth with an email whitelist for access control, and build a small responsive web app that reads live item prices, calculates quotes instantly, saves them into a separate archive sheet, and allows reopening/editing later without touching the original price sheet. I would build this using a lightweight React frontend with Google Sheets API integration and deploy it on Vercel so hosting and maintenance stay simple. The quote archive would store structured quote data (items, quantities, totals, user, date) so editing and resaving works cleanly. I would request to connect once so we can review your current Google Sheet structure, confirm the formula logic for pricing, and finalize the exact quote archive format before I start development. Thanks, Rahul A.

Building a drone quote calculator requires clean logic to handle variable inputs and provide accurate pricing estimates. I can structure this app to be user-friendly, responsive, and easy to integrate into your existing site. With 15 years of experience in PHP, JavaScript, and custom web development, I regularly build functional tools rather than just static pages. I understand how to manage the backend calculations and front-end interaction necessary to make this calculator perform reliably. I can complete this for $429.97 within 1 day. Send me a message so we can discuss the specific variables for your drone quotes and get this running.

@kamran2012

Hi, I will build your drone quote calculator — Google OAuth with email whitelist, live item/price pull from your Sheet, quantity-based totaling, and automatic write-back to your Quotes-Archive Sheet with edit/resave support. I will use a lightweight React frontend on Firebase Hosting with Firebase Functions handling the Sheets API calls. This keeps your Google credentials server-side rather than exposed in the browser, and Firebase Auth natively supports Google OAuth — so the whitelist check happens before any data loads. Questions: 1) Do you need the per-quantity rate formula to support tiered pricing (e.g., discount above a certain quantity), or is it strictly linear for now? 2) How many items does the price Sheet currently hold — dozens or hundreds? This affects whether I batch-load or paginate. Looking forward to discussing further. Best regards, Kamran

@extreamcode

Hi, I can already see the real pain point here: you don’t want another spreadsheet task, you want a simple quote tool that feels invisible in daily use. I’ve built lightweight web apps in PHP and JavaScript with clean software architecture, and this fits well with a small Flask/Node backend or a lean frontend around Google Sheets API. I’ll set up Google OAuth with whitelist access, pull live item data from Sheets, calculate quantities and totals in real time, and write every saved quote into Quotes-Archive without touching your source sheet. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I can also make quote reload/edit/resave smooth for two-person day-to-day use, with deployment notes for Firebase, Vercel, or similar. If you want, I’ll structure it so the formula can be tweaked later without rewriting the app. Could you confirm whether you want the saved quotes to reopen by quote ID, date, or a simple search list? Do you need any role separation beyond the whitelist, such as admin vs viewer? Should the archive sheet store one row per quote, or one row per line item? Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

@ahsansaleemnaz

I'll build this in React with a Node.js backend — Google OAuth with email whitelist, live price fetching from your Sheet, quantity-based calculation, quote archive write-back, and reopen/edit functionality. Deployed to Vercel with clear deployment instructions. Do you already have a Google Cloud project set up with Sheets API enabled, or does that need configuring from scratch?

@managersingh

Hi I will build a lightweight, mobile-friendly web app using Vanilla JS or React that integrates with the Google Sheets API for your spray-job quotes. I'll configure Google OAuth with an email whitelist for secure access and set up the interface to fetch item prices and calculate totals dynamically. The app will write quotes to a "Quotes-Archive" sheet and enable quick edits on saved entries, complete with clear Vercel or Firebase deployment steps. Best regards, Singh

@Herculesz

Hi I can build a lightweight quote web app using Google OAuth, Google Sheets API, and a simple React, Vue, or Node-based structure that stays easy to host and maintain. The main technical challenge is keeping the original pricing sheet untouched while securely reading live item data, calculating quote totals, and saving editable quote records into a separate archive sheet. I can solve this by setting up OAuth login, checking the signed-in email against a whitelist, then loading item names and base prices directly from your Google Sheet. The quote page can include quantity inputs, real-time line totals, a grand total, and a clean calculation layer that leaves room for future formula changes. On submission, the app will write the quote date, user email, items, quantities, line totals, and grand total into the Quotes-Archive sheet. I can also add a saved-quotes view so you and your uncle can reopen previous quotes, edit quantities, and resave updated versions without touching spreadsheets. I will keep the UI simple, mobile-friendly, and provide clear deployment instructions for Firebase, Vercel, or a similar hosting option. Thanks, Hercules
