@esolzsales

I understand you need an internal system to manage the team and your daily workings I would love to discuss how you create quotes, how you utilise them and what does team have permissions to do A detailed discussion would be helpful in giving a fair budget and timeline Let me know if we can connect and go over things

With over a decade of experience in full-stack architecture and high-scale systems, I understand the need for a streamlined HVAC Estimate & Proposal Platform for your contracting company. My background in creating high-security systems for over 1 million users directly applies to the challenges of developing a web-based system with companion Android and iOS apps that streamlines job estimates and proposal creation. A strategic insight for this project would be to implement a centralized back-end logic that calculates material, labor, markup, and tax to ensure accurate estimates and proposals. My past success in building Telegram Mini Apps for scaling user interactions showcases my ability to handle the complexity of this project. I encourage you to reach out to discuss your project roadmap further. Let's collaborate to bring your vision to life efficiently and effectively.

Hi, Your HVAC Estimate & Proposal Platform caught my eye. I've built strong visual identities for Uzbekistan brands across logo, illustration, UI/UX, and character design. Design work I've done: - Brand identities & logo systems - UI/UX design in Figma (web & mobile) - Character design & mascots - Illustration & icon systems - Web mockups & design systems - Adobe Creative Suite (Photoshop, Illustrator, After Effects) - Brand guidelines & design documentation - Social media & marketing assets My skills: PHP, Mobile App Development, Android, HTML5, Proposal Writing, UI / User Interface, Web Development, iOS Development + Figma prototyping, user research, design thinking, accessibility, animation, and brand strategy. Key question before I quote: Who is your audience and what feeling should this design give them? The best design isn't pretty—it's strategic. It communicates and converts. Let's do a 20-min call to understand your vision, audience, and goals. What timezone are you in? I respond within 1 hour. Kausar & Team

Hi there, I’ve read your HVAC Estimate & Proposal Platform brief and I’m confident I can deliver a clean, minimal, browser-first web app with rock-solid cross‑platform mobile support. I’ve built end-to-end quoting and proposal systems for service industries, with a focus on simple data entry, real-time pricing, and branded client documents. What I’ll build for you: a responsive web app (plus Android/iOS) that lets your team enter job details, choose equipment, and instantly see itemized estimates (materials, labor, markup, tax). A single click generates a polished client proposal (PDF and shareable web link) that preloads the exact figures, scope, and terms. Admin controls to update price tables, equipment, and branding. A minimalist UI that stays fast and distraction-free in the field. Tech approach: React or Vue frontend, a robust Node.js or Laravel backend, and a cross‑platform mobile layer via Flutter or React Native to cover Android and iOS with a consistent UX. I’ll tailor the data model to your pricing spreadsheets and deliver a secure, scalable system with a 30‑day post‑launch support window. 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. What is the preferred invoice/branding style for the PDF (fonts, colors, and logo usage), and do you want the on-site quotes to require online connectivity or should offline caching be supported for field work

@espsofttech

Hi there, In one of our recent projects we delivered a field-quoting and proposal system for a service-based business where technicians could build estimates on-site and instantly convert them into branded client-ready proposals without using spreadsheets or external tools. As this is very similar in nature—where speed, accuracy, and a clean estimation flow are more important than anything else—we can build you a single unified system that replaces your current manual quoting process with a real-time, browser-based estimator + proposal generator. We will build a web-based application where your team can enter HVAC job details, select equipment, and instantly see live calculations for material, labour, markup, and tax, and then generate a professional PDF or shareable proposal link directly from the same data. We will also extend the same system into mobile apps so your technicians can create and adjust quotes on-site, with everything syncing back to one central system. I would request to connect once so we can quickly go through your current pricing format and map it properly into the system. Thanks, Rahul A.

I will create a fully functional web application with Android and iOS builds, a back-end logic system for accurate estimates, a proposal generator for client-ready documents, and an admin area for easy updates. - MY WORK STATS: ✨ https://www.freelancer.com/u/XanvraTECH I would appreciate the opportunity to discuss this project further and showcase how my experience can benefit your company. Best regards, Warda Haider

@Srashtasoft

Hi there, We can build this as a unified system using React or Vue for the web dashboard, Flutter for cross-platform mobile apps, and a robust backend (Node.js or Laravel) with a structured pricing engine. The system will calculate materials, labor, markup, and tax dynamically, then convert estimates into branded, client-ready proposals. Admin controls will allow easy updates to pricing tables, equipment, and branding. The focus will be on speed, clarity, and a distraction-free user experience. Our approach includes architecture planning, UI/UX design based on your brand, pricing logic implementation, proposal generation module, and deployment with scalable cloud infrastructure. We also ensure responsive performance across devices and provide post-launch support. Questions: ========= Do you want offline functionality for technicians while quoting on-site? Should proposals support e-signatures or approval tracking? Do you have fixed pricing formulas or do they vary per project/job type? Will there be multiple user roles (admin, estimator, technician)? Best Regards, Srashtasoft Team

@Herculesz

Hi I can build a web-based HVAC estimating and proposal system with companion iOS and Android apps so your office team and field technicians can quote jobs from one streamlined platform. The main technical challenge is converting your pricing spreadsheets into accurate calculation logic for material, labor, markup, tax, equipment options, and proposal-ready outputs without requiring extra software. I would recommend React or Vue for the web dashboard, Node.js/NestJS or Laravel for the backend, PostgreSQL for pricing and estimate data, and React Native or Flutter for the mobile apps. The system can include a clean estimating workflow, real-time price updates, admin-managed price tables, equipment lists, branding controls, PDF generation, and shareable proposal links. I can also structure the proposal engine to pull calculated figures, scope of work, terms, company branding, and itemized breakdowns into a polished client-facing document. The final platform will be responsive, secure, easy to manage, and designed around a minimalist interface that keeps quoting fast for technicians and office staff. Thanks, Hercules

@kishanbwts

I’ve built similar end-to-end quoting platforms for service businesses that needed fast estimate updates and seamless proposal generation. Based on your needs, I’d suggest React for the web front end paired with Node.js on the back end—this combo offers real-time updates and clean API support. For mobile apps, React Native keeps the UI consistent across Android and iOS while sharing much of the codebase. The core logic will handle material, labor, markup, and tax calculations dynamically, so any input change instantly refreshes the price. The proposal generator will produce branded PDFs and web links pulling data from the estimate without manual input. The admin panel will let you update price tables and assets easily, keeping everything centralized. A couple of questions: How complex are your current pricing rules—in particular, do any calculations depend on variable job factors or tiered pricing? Also, do you need offline quoting capabilities on the mobile apps for sites with poor connectivity? I estimate 8 to 10 weeks for a full rollout, including testing on multiple devices. Ready to start once you share your sample spreadsheets and branding.
