Inventory System on Google Sheets
- Thread starter dburd

Hello Dburd,
Thank you for sharing your file. The structure you’ve created is a solid starting point for an inventory system. To make it more automated and efficient in Google Sheets, I would suggest a few improvements.
1. Separate Product List and Transactions
Instead of updating stock numbers manually, it is better to separate your data into:
Sheet 1: Products (Master List)
2. Automate Stock Calculation
In the Master sheet, you can calculate stock dynamically using formulas:
Total Stock In:
=SUMIF('Stock In'!B:B, A2, 'Stock In'!C:C)
Total Stock Out:
=SUMIF('Stock Out'!B:B, A2, 'Stock Out'!C:C)
Current Stock:
=Opening Stock + Total Stock In - Total Stock Out
This way, you never need to manually adjust stock levels.
3. Add Low Stock Alerts
You can add Conditional Formatting to highlight items that need restocking using:
=Current_Stock <= Reorder_Level
This will automatically alert you when inventory is low.
4. Improve Accuracy

1. Separate Product List and Transactions
Instead of updating stock numbers manually, it is better to separate your data into:
Sheet 1: Products (Master List)
- Item ID
- Item Name
- Category
- Unit Price
- Opening Stock
- Reorder Level
- Date
- Item ID
- Quantity
- Date
- Item ID
- Quantity
In the Master sheet, you can calculate stock dynamically using formulas:
Total Stock In:
=SUMIF('Stock In'!B:B, A2, 'Stock In'!C:C)
Total Stock Out:
=SUMIF('Stock Out'!B:B, A2, 'Stock Out'!C:C)
Current Stock:
=Opening Stock + Total Stock In - Total Stock Out
This way, you never need to manually adjust stock levels.

=Current_Stock <= Reorder_Level
This will automatically alert you when inventory is low.
- Use Data Validation dropdowns for Item ID to avoid typing mistakes.
- Protect formula columns so they are not accidentally edited.
- Optionally, create a small dashboard to show total inventory value and low-stock items.

You can handle this with a timestamp script rather than formulas, since formulas will keep updating. A simple Apps Script on edit can lock the date and then you can use a formula to carry the last value forward. Do you want the timestamp only on first entry or every change?

Hello Jasperstone62,
Thanks for your contribution. If you're referring to building or improving an inventory system in Google Sheets, the approach usually depends on how dynamic and automated you want it to be. A basic setup can work well with formulas (like SUMIF, FILTER, or QUERY) to track stock in/out and current balance.
However, for more advanced features such as automatic updates, alerts for low stock, form-based entry, or multi-user interaction, you may need to use Google Apps Script (the Google Sheets equivalent of VBA). This allows you to automate tasks and create a more robust system.
