Inventory System on Google Sheets

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:

- 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.
