Mobile Retail POS & Operations App

A tailored point-of-sale and business management Android application built for a high-volume mobile phone retail and repair counter. Built specifically around the fast-paced nature of physical electronics shops, the app merges hardware sales, trade-ins, and technician repair ticketing into a frictionless single-screen workflow.

The retailer relied on handwritten bill books and disjointed desktop software that proved too rigid for counter sales. When a single customer purchased an accessory, submitted a device for screen replacement, and negotiated an old phone trade-in, generic POS tools failed to bundle these operations, causing counter congestion, unrecorded repair status, and missing invoice archives.

Rajni Techie built a lightning-fast, mobile-first Android POS application. Counter staff can snap device condition photos on intake, select parts or accessories from an indexed catalog, apply discounts, generate formatted PDF receipts, and dispatch them to the customer via WhatsApp in seconds.

• Unified checkout handling retail product sales, repair labor, and device trade-ins
• Device camera integration to photograph physical item conditions and serial numbers
• Instant branded PDF invoice generation with itemized parts and warranty terms
• One-touch WhatsApp invoice and repair completion dispatch
• Live inventory tracking and low-stock alerts for high-demand accessories
• Customer purchase and repair history lookup by phone number
• Daily counter cash reconciliation and end-of-day sales overview

Transformed counter operations into a swift, searchable, and professional experience. Checkout times dropped dramatically, customer disputes over device condition were eliminated through photo logs, and the shop owner gained effortless daily sales tracking.
