Setup

Google Sheet is the shop ledger. Set it up once on a computer, then open this app on every phone.

Saving on this phone only

PIN •••••• · other phones cannot see this stock

1. Create the sheet

  1. 1On a computer, open sheets.new and name it Arifa Telecom.
  2. 2Menu: Extensions → Apps Script. Delete the starter code.
  3. 3Paste the script below and click the disk to save. The PIN •••••• is already inside it.

2. Publish it as a web app

  1. 4In Apps Script: Deploy → New deployment.
  2. 5Type: Web app. Execute as Me. Who has access: Anyone — not “Anyone with a Google account”.
  3. 6Click Deploy. Google may say the app isn’t verified: Advanced → Go to Arifa Telecom (unsafe). It is your own script. Click Allow.
  4. 7Copy the Web app URL. It ends with /exec.

3. Paste the URL

Use “empty sheet” for a real shop start. Use “copy this phone’s stock” if you already typed real items here (not the sample list).

4. Other phones

On the next phone, open this app → Setup, and paste the connection code. Same Google Sheet, same PIN.

Connect a sheet first to get a code.

This phone only

Fine for trying the app. Stock will not follow him to a second phone until the sheet is connected.
