Free Sales & Inventory App – Use, Explore, Learn, Customize | AppSheet Template

Introduction

Managing sales, purchases, and inventory is a common challenge for small businesses. Many people rely on spreadsheets, which are familiar but can become difficult to maintain as the data grows.

To provide an alternative, we created a small Sales & Inventory app with AppSheet. This app is shared for free, and anyone can:

• Use it as a ready-to-go tool for daily records.

• Explore how the app is built in AppSheet.

• Learn AppSheet functions by looking into the structure.

• Customize it for your own business needs.

It’s not a full ERP or accounting system, but rather a simple starting point.

Why We Built This App

We noticed similar problems across different users:

• Sales and purchase data scattered in multiple files.

• Inventory numbers not matching the actual stock.

• Unclear tracking of customer payments or supplier balances.

• No quick overview of best-selling products.

The app was built as a lightweight option: more structured than spreadsheets, but still accessible for anyone without technical skills.

About the App

This app was built using Google AppSheet, a no-code platform that turns spreadsheets into apps.

• Works on both desktop and mobile.

• Requires no coding.

• Data is stored in Google Sheets.

• Shared directly from AppSheet, so users can access it with their Google or Microsoft account.

👉 For small shops and end-users: this means you can use the app right away if you already sign in with Google or Microsoft.
👉 For developers and learners: this is a free template to explore how AppSheet apps are structured and try customizing it.

Key Features

• Sales Orders – Record sales with customer details, products, and quantities.

• Purchase Management – Log supplier purchases and stock entries.

• Inventory Tracking – View current stock levels with auto-updates.

• Payments & Balances – Track customer payments and supplier debts.

• Dashboards – Simple charts for the last 30 days: sales by channel, revenue, and top products.

• Master data management: products, customers, suppliers, product groups, and sales channels

Benefits

This app is not meant to be a “complete solution,” but it can be useful in different ways:

• For small business owners: a simple tool to keep records organized.

• For end-users: a lightweight way to manage sales and stock without setting up complicated systems.

• For developers/learners: a practical template to study AppSheet functions, experiment with customization, and speed up learning.
