Agro Ledger - Smart Agricultural Finance Management
A specialized ledger and settlement system for agricultural businesses to manage complex customer debts, crop-based payments, and interest tracking.
Project Overview
A comprehensive enterprise solution designed for agricultural trade centers. Agro Ledger automates the complex process of settling customer bills using a mix of cash and crop payments (Paddy/Corn). The system handles real-time interest calculations, manages inventory-based payments, and features a custom-built thermal printing engine designed to solve Unicode rendering issues in regional languages.

Challenges & Solutions
Regional Language POS Printing
Standard thermal printers do not natively support Sinhala Unicode, leading to broken glyphs and unreadable receipts.
Engineered a bitmap-based printing pipeline using html2canvas. Implemented a font-ready synchronization layer with a precise rendering delay to ensure complex ligatures are fully shaped before image capture.
Crop-to-Cash Settlements
Calculating final balances when payments are made in fluctuating commodity weights (Paddy/Corn) mixed with cash and interest.
Developed a robust settlement algorithm that normalizes commodity values based on unit prices and deducts them from a prioritized list of outstanding debts.
Offline Local Environment
The system must operate in remote agricultural hubs without reliable internet connectivity.
Optimized the entire stack for local Laragon/WAMP environments, removing all external CDN dependencies and implementing local asset management for libraries like SweetAlert and html2canvas.
