System

Billing & Inventory Management System is a custom SaaS billing and inventory platform built for a marble and tiles trading business to replace manual, paper-based operations. It handles GST-compliant billing with instant PDF invoice export, centralized customer and order management, a services/items catalogue, and store profile management for consistent branding. A standout feature is the customer share page, letting buyers view invoices without logging in, paired with WhatsApp reminders for unpaid orders to speed up collections. A real-time dashboard gives the owner instant visibility into recent sales — all accessible from any browser, with no installation needed.

Challenge

The client, a marble and tiles trading business, was managing billing, GST calculations, and stock records manually across registers and spreadsheets. This made it hard to track which customers had pending payments, generate GST-compliant invoices quickly, or get a clear picture of daily sales — leading to billing errors, delayed follow-ups, and lost time during peak order periods.

Solutions

Built a web-based billing and inventory platform covering the full sales cycle: GST-compliant billing, a customer database with order history, a services/items catalogue for the store's product range, and store profile management for invoice branding. Every invoice can be exported as a shareable PDF, and a customer-facing share page lets buyers view their bill from any device without logging in. To close the loop on collections, unpaid orders trigger a one-click WhatsApp reminder to the customer, and a dashboard surfaces recent sales at a glance so the owner always knows where the business stands — accessible from anywhere, not just one desktop.

Success Metric

Replaced manual, error-prone billing with a cloud-accessible system that generates accurate GST invoices in seconds, keeps every customer's order and payment history in one place, and gives the owner a real-time view of sales and outstanding dues — from the shop, home, or on the move. Payment follow-ups that used to rely on memory or phone calls are now a single WhatsApp tap.
