Smart Billing System for Small Retailers – POS Software
Problem
Our client, a regional bookstore chain with legacy systems, faced slow billing, manual inventory tracking, and compliance issues with invoicing. Staff were frustrated with error-prone spreadsheets and lost sales data.
Challenge
Replace outdated, manual billing and inventory processes with an efficient, user-friendly desktop POS that meets new compliance standards and minimizes training time for non-technical staff.
Solution
Megicode designed and delivered a desktop POS system using JavaFX. The solution featured real-time inventory CRUD, batch product import, a visual sales dashboard, and one-click PDF invoice generation with tax calculations. We provided hands-on training and a migration script for legacy data.
Impact
Billing time dropped by 30%. Monthly revenue tracking improved, and manual errors in inventory management were reduced by 80%. The system enabled compliance with new tax regulations and improved customer checkout experience.
Implementation
The project was delivered over 6 weeks, with weekly check-ins and a dedicated phase for data migration. The final rollout included in-person training for all store staff and a two-week support window for post-launch troubleshooting.
