Automated Billing & Inventory System

Cut invoicing time by 80% and eliminated manual stock errors with a unified digital ecosystem.

Client Context

PD Turbo Tech is a specialized automotive service center handling 50+ vehicles daily. They managed hundreds of distinct spare parts manually, generating invoices and tracking inventory primarily on paper and basic spreadsheets.

The Problem

Time-Consuming Invoicing

Service advisors spent up to 15 minutes manually writing invoices and cross-referencing part prices.

Stock Discrepancies

Without real-time inventory tracking, staff often committed parts to customers that were out of stock.

Missing Analytics

The owner had no immediate visibility into daily revenue, top-selling services, or inventory costs.

Our Solution

We deployed a comprehensive digital ecosystem using a React Native tablet app for advisors and a Node.js web dashboard for management, backed by a robust PostgreSQL database.

Digital Job Cards

Advisors can create job cards directly on tablets, instantly syncing with the parts department.

Live Inventory Sync

Stock levels update automatically as parts are assigned to jobs. Low-stock alerts are sent instantly.

1-Click Invoicing

Invoices are generated instantly from completed job cards containing accurate parts and labor costs.

Executive Dashboard

Real-time analytics for revenue, parts consumption, and mechanic performance trackable from anywhere.

Implementation

Week 1: System architecture and database design. Audited their existing parts spreadsheet to prepare for migration.

Week 2-3: Front-end app development and back-end inventory logic construction. Conducted pilot testing with senior advisors.

Week 4: Full deployment and staff training. Migrated all previous service records into the new system.
