Hello MODA Windows & Doors team, your goal to manage Lead → Customer → Quotation → Follow-up → Closing → Invoice → Receipt → Installation → Reporting in Google Sheets + AppSheet is exactly what I excel at. This is my speciality: turning fragmented sales processes into a single, auditable workflow that speeds decisions and improves forecast accuracy. I'm Iosif Peterfi, 15+ years helping businesses design practical, outcome-driven systems. I bring a business-minded approach that reduces admin time while boosting visibility for leadership and sales teams. My approach: I'll deliver a fully integrated system with core features: 1) Customer Management 2) Quotation with multiple items and sqm pricing 3) Discount controls with admin approvals 4) Sales Pipeline from Lead to Closed Won/Lost 5) Sales Activity Tracking 6) KPI tracking aligned to targets 7) Invoicing & Receipts 8) Project tracking (installation, warranty) 9) Photo uploads 10) Real-time dashboards and alerts. The result is faster quotes, tighter discount governance, stronger cash flow, and clear performance insights. Milestones cover data model setup, rule-based automation, dashboards, user training, and go-live support, with risk reduced by role-based access and audit trails. Last month I helped a regional furniture retailer migrate their sales workflow to Sheets + AppSheet; onboarding time dropped from 3 days to 1 day and quotes accuracy improved by 18%.

@mayankinnovative

Hi, As per my understanding: You need a complete business management system built on Google Sheets + AppSheet that covers your full sales lifecycle—from lead capture to installation and reporting—while handling quotations, approvals, KPIs, and real-time tracking in a structured and automated way. Implementation approach: I will design a scalable data structure in Google Sheets (customers, leads, quotes, invoices, activities, etc.) ensuring relational integrity. Then, I’ll build an AppSheet app with role-based access, automated workflows, and conditional logic (e.g., discount approval triggers). The quotation module will support multi-item sqm pricing, while pipelines and KPI tracking will be visualized via dashboards. I’ll also integrate photo uploads, alerts, and reporting for real-time insights. The system will be tested thoroughly to ensure smooth end-to-end flow from lead to project completion. A few quick questions: 1. Do you have an existing Google Sheet structure or starting from scratch? 2. How many user roles (admin, sales, manager) are needed? 3. Any specific format for quotations/invoices? 4. Do you need mobile-first usability for your sales team?

@Aaleen110

I understand you need a robust AppSheet and Google Sheets system to streamline your premium window and door CRM, automated quotation generation, and sales KPI tracking. I will design a normalized backend architecture in Google Sheets to serve as the single source of truth for your CRM and KPI data. I will then configure AppSheet automation pipelines to handle server-side PDF generation for quotations and real-time data sync for sales performance monitoring. Do you have an existing quotation template that I should integrate into the AppSheet PDF automation? I am ready to start immediately and can share a draft data structure for your feedback. Best regards, Aaleen
