Managing stock manually can be frustrating, whether it’s tracking items, updating quantities, or monitoring low-stock alerts, things can easily get messy. With NotionApps, you can turn your Notion databases into a fully functional inventory management app that works seamlessly on desktop and mobile.
In this guide, I’ll walk you step by step through building a simple yet powerful inventory management system using Notion databases inside NotionApps.
Select the Notion databases you want to include and hit Build App.
For this project, the main screens we’ll be creating are:
Inventory – to view all stock items
Withdraw Stock – to track stock going out
Add Stock – to log new stock coming in
View Products – to display product details
Step 2: Add Users
From the left sidebar, go to the Users section.
Click on Selectuser database and choose Employees.
Login method - Email address + Login Code
Email address property - Email
Username property - Name
Turn the Allow users to sign up toggle on.\
Click Confirm.
This will allow you to tag employees whenever stock is withdrawn or added, keeping accountability clear.
Step 3: Clean the Workspace
Delete all the default screens that are auto-generated. We’ll start fresh with customized screens tailored for inventory management.
Step 4: Build the Inventory Screen
Create a new screen:
Click New Screen → Select Products Database → Choose List Update Items → Name the screen Inventory.
Style Settings:
Change View Type → Grid
Grid Size → Small
Grid Image → Square
Data Settings:
Title → Name
Description → Categories → Name
Caption → Current Stock
Color Tag → Low Stock < 5, By “Low Stock <5”, we’re setting a threshold: any item with current stock strictly less than 5 units will be highlighted with a specific color tag. You can adjust this threshold to suit your inventory norms.
Add 2 new tags - Stock Low (red) and Stock Ok (Green)
Image → Image
Behaviour Settings:
When an item is clicked, set action → Go to Update Screen.
Add new Logic → View name, View current stock, View Low Stock<5 & Update categories
Delete Logic → Update SKU & View Categories
Turn the Show Scanner toggle on.
Step 5: Configure Withdraw Stock
Under List Withdraw Stock:
Title → Date
Caption → Employee – Name
Color Tag → Quantity Withdrawn
Behaviour → Change Allow Adding → Direct Add
Configure Withdraw Form (click ➕):
Delete Name entry
Delete Employee section
Add Label - The current employee is automatically captured when withdrawing stock.
Add Action → Set Employee = Logged-in User
Behaviour → Change Save Button Text → WITHDRAW
Follow similar steps to configure the Add Stock. The only difference is you’ll track quantities coming in rather than going out.
Step 6: Build the View Products Screen
Create another screen:
New Screen → Select Product Database → Choose List View → Name it View Products.
Apply the same Style and Data settings as the Inventory screen.
Under Behaviour → Go to Screen, configure views:
View Name → Show Image + SKU
Include details: Categories, Withdrawn Stock, Add Stock, Low Stock Status
This screen acts like a detailed product catalog, showing all relevant product details.
Step 7: Add a Withdraw Stock Form Screen
Add a new screen:
Select Withdraw Stock Database → Choose Form Add Item.
Configure form fields:
Input Product → Required (Allow Multiple = OFF)
Quantity Withdrawn → Required
Input Date → Required
Employee Label → Auto-tag employees based on login
Add Action → Set Employee = Logged-in User.
Follow similar steps to create an Add Stock Form Screen, except here we will be adding stock data into the database.
This ensures each transaction is tied to a specific staff member for accountability.
Step 8: Update Navigation
Go to Edit Navigation and rename your tabs to match your app’s flow (Inventory, Add, Withdraw, Products).
Update icons for a more intuitive interface.
Wrapping It Up
And that’s it! You’ve now built a fully functional Inventory Management App in NotionApps. Your app can:
Show an organized Inventory Dashboard
Let employees add or withdraw stock with accountability
Display a product catalog with categories, stock levels, and SKU details
Track all stock movements with proper logs
This system is lightweight, customizable, and runs directly on your existing Notion databases. Once you’ve set it up, you can scale it further by adding analytics, supplier tracking, or automated notifications when stock runs low.
With a little setup effort, you’ve turned Notion into a full-fledged inventory tool.
Pro Tip: NotionApps already offers a ready-to-use Inventory Management template that you can customize to fit your needs, along with many other templates designed for different use cases.
