I Built a Complete POS System for Mobile Phone Shops (WhatsApp + Repairs + Inventory)

Build a complete FREE mobile shop management system in Google Sheets — with a full POS, inventory tracking, repair jobs, IMEI tracking, automated WhatsApp messages, EMI installments, and multi-user roles. No coding required. $0/month hosting.

If you run a mobile phone shop, phone repair business, or electronics store, this Google Sheets inventory management system will replace expensive software with a professional, fully custom solution you own for free.

🛒 Point of Sale (POS) — process sales, apply discounts, print thermal & A4 invoices
📦 Inventory Management — real-time stock adjustments, accurate stock valuation
🔧 Repair Job Management — log jobs, assign technicians, track status & send WhatsApp updates
📱 Buy Used Phones — IMEI capture, grading, condition tracking & auto purchase contracts
🔍 IMEI Lookup — full device history (sales, repairs, purchases) across your entire business
💬 Automated WhatsApp Messages — notify customers on sales receipts & repair completion
💳 EMI & Installment Plans — create payment plans, track paid and pending installments
👥 Multi-User Role Access — Owner, Manager, Employee roles with granular permissions (no code changes)
🏪 Supplier & Customer Profiles — complete records with purchase and repair history
