Key Features

Multi-branch POS Barcode scanner billing Cashier shifts Sales 360 view Barcode label printing Stock per branch Branch stock transfers Purchases and suppliers Customers register Supabase login and database Secret key in Apps Script Google Sheet backup Drive image uploads Dashboard themes In-app notifications Free Blogger hosting

Description

A complete multi-branch point of sale system that runs on a free Blogger website. Supabase holds the login and the database, and a small Google Apps Script web app sits in the middle: it keeps the Supabase secret key safe in Script Properties, backs the data up to a Google Sheet and stores product images in Google Drive.

What the POS does

Cashiers open a shift and bill with a barcode scanner. Every sale has a 360 view, products get printable barcode labels, and stock is kept per branch, with transfers between branches, purchases from suppliers and a customer register. The dashboard comes with themes and notifications.

How it is set up

  • Upload the blogger.xml theme to a new Blogger blog with Edit HTML
  • Create a Supabase project and build the database with schema.sql in the SQL editor
  • Paste code.gs into a new Apps Script project, deploy it as a web app and add the Supabase keys to Script Properties
  • Sign up the first Admin, confirm the email, set up the store and load the demo data

The full setup is shown step by step in the video, and a setup guide page ships with the code.

Who it is for

Shops with more than one branch that want one POS for every counter without paying for hosting: Blogger hosts the app for free and the Supabase free plan is enough to start.

Brilliant project! πŸ‘πŸ”₯ Combining Blogger, Supabase, and Google Apps Script to build a complete multi-branch POS system is a very creative and cost-effective approach. I especially like the secure secret key management, barcode billing, branch-wise inventory, stock transfers, sales tracking, and Google Drive integration. Using Blogger as the frontend with Supabase as the database opens up exciting possibilities for building scalable business applications without expensive hosting. Excellent work! Looking forward to more innovative ERP and POS projects. πŸš€πŸ’»
