Description

A point of sale built specifically for mobile phone shops — because a phone shop is not a grocery. You sell handsets and accessories, you take devices in for repair, you buy used phones off customers, and you sell on instalments. This handles all four in one system on Google Sheets, with a permission matrix you edit without touching code.

IMEI lookup ties it together

Every handset that passes through the shop carries its IMEI — bought as used stock, brought in for repair, sold to a customer. Type an IMEI into the lookup and you get the full history of that device across your whole business in one screen. That is the difference between a generic POS and one built for this trade.

What it does

At the counter, search stock, pick a walk-in or saved customer, apply a discount, take payment and let it calculate the change — then print A4 or thermal, at 58mm or 80mm. Repairs are logged against a technician with the device IMEI, passcode, warranty days and the parts used, and those parts come straight out of inventory. Used-phone purchases record ID type, ID image, grade, battery health and screen and body condition, and print a purchase contract. Instalment plans track what is paid and what is due, with WhatsApp reminders.

Highlights

  • Returns that restock automatically, per line, with a reason and refund method
  • Cash drawer with opening float, expected, counted and the variance when you close the till
  • Loyalty points with earn rate and redemption value you configure — spend a set amount, earn a point, redeem it as tender
  • Supplier profiles showing exactly which products came from whom
  • Customer profiles combining their sales, repairs and payments in one view
  • Role and permission matrix — take edit rights off an employee and it applies immediately, no redeploy
  • Reports for revenue, collected, profit and loss, top products and payment breakdown

Who it is for

Mobile phone retailers and repair shops, especially those who also buy used handsets or sell on instalments and currently track repairs in a notebook.

Requirements

  • A Google account (Gmail or Google Workspace)
  • Google Sheets as the database — no server or MySQL needed
  • Google Apps Script web app deployment access
  • Google Drive space for product and ID images
  • Optional: 58mm or 80mm thermal printer for receipts
  • Optional: a WhatsApp API if you want automated customer messages
  • Modern browser (Chrome, Edge, Firefox or Safari)

Hi Rameez! 👋 First of all, congratulations on the channel and on the incredible work you've been doing with Apps Script, PHP, React, and AI. 350+ projects and 23K+ subscribers is a real achievement — your tutorials are a goldmine. I searched your channel but couldn't find anything for the legal/lawyer industry (case management, client intake, contracts, deadlines, etc.). Do you have any plan to build something for lawyers, or is this something you could develop as a custom project? Thanks and keep up the amazing work! 🙌

I want you to create a Car Rental Management System for car rental agencies. The system should support multiple user roles, including Administrator, Manager, and Employee, each with appropriate permissions. It should allow users to: * Add, edit, and manage vehicles. * Add, edit, and manage customers. * Manage vehicle documents (registration, insurance, inspection, etc.). * Track vehicle maintenance and service history. * Record expenses and operating costs. * Manage rentals, returns, and reservations. * Handle payments and invoices. * Monitor vehicle availability and status. * Generate reports and statistics. * Include any other essential features required for efficiently managing a car rental business.
