Project Title:
BuildQuote TMT – Construction Material & Steel Rod ERP, Estimator & Billing App
Project Overview:
BuildQuote TMT is a full-featured, offline-first Android ERP and Quotation Management application engineered specifically for steel dealers, TMT bar distributors, hardware merchants, and civil construction contractors. It eliminates manual calculation errors by automating weight-to-price conversions, GST taxation, labor/freight charges, and instant PDF invoice generation.
Key Features Implemented:
Automated TMT Steel & Rod Estimator:
Supports 13+ industry-standard rod diameters (3mm to 32mm, including 8mm lite) with customizable per-rod unit weights and daily per-KG market rates.
Pre-loaded with top steel manufacturers (Tata Tiscon, Vizag Steel, JSW Neosteel, Simhadri TMT, Jindal Panther, Kamdhenu, etc.) plus custom brand creation.
Built-in calculator for Binding Wire requirements, Loading/Unloading labor auto-calculation (per metric ton), transportation/freight charges, and commercial site taxes.
Dedicated Cement Estimation Module:
Standalone estimation workflow for 23+ major cement brands (UltraTech, Ambuja, ACC, Shree, Dalmia, Ramco, etc.) with bag-count pricing, freight, and tax calculation.
Smart Optical Scanner (OCR & Image Recognition):
Allows dealers to snap a photo via Camera or pick from Gallery to scan handwritten site notes or structural bundles and automatically populate rod counts into the estimation sheet.
Instant PDF Tax Invoice & WhatsApp Sharing:
Generates branded, print-ready A4 PDF quotations and tax invoices complete with custom Company Logo, GSTIN, Bank Account/IFSC details, and Authorized Digital Signature.
One-tap sharing via WhatsApp (formatted text summary or direct PDF attachment).
Construction Vault (ERP Records & CRM):
Local SQLite/Room database storing all historical quotations with one-click duplicate, edit, delete, and re-share capabilities.
Includes Customer & Supplier directories and stock/inventory tracking by rod size.
Enterprise Offline Licensing & Anti-Tamper Security:
Protected by a 6-digit PIN Lock Screen and a cryptographic SHA-256 Offline Subscription License Key system tied to Store IDs and expiration dates.
Features System Clock Tamper Detection to prevent users from rolling back device dates to bypass subscription expiry.
Multi-Language Localization:
Seamless real-time switching between English, Telugu (తెలుగు), and Hindi (हिन्दी) for regional business accessibility.
Tech Stack & Architecture:
Language & UI: 100% Kotlin, Jetpack Compose (Material Design 3), Smooth 90Hz/120Hz High-Refresh-Rate Hardware Accelerated UI
Architecture: MVVM with Clean Repository Pattern & Kotlin Coroutines
Local Persistence: Android Jetpack Room Database (SQLite) & SharedPreferences
Networking & Scanning: OkHttp, Retrofit, Moshi JSON, Multimodal Image Processing
Document Engine: Native Android PdfDocument Canvas rendering for crisp, zero-dependency PDF invoice generation
