How to Create an Excel Inventory Tracker Based on Customer Orders
Question details
The user needs to build an automated Excel workbook to track inventory for products by subtracting ordered quantities from starting stock based on attributes like brand, color, size, and category.
- Product
- Excel
- Device & OS
- not provided
- Scenario
- Setting up a dynamic inventory management system to track product stock levels based on incoming customer orders.
- Observed behavior
- Inventory levels must update automatically when customer orders are entered, accurately matching items by their specific variations and subtracting the ordered quantities.
Gather all your starting stock levels and clearly define the attributes such as brand, color, size, and category for each product variation before setting up your tables.
Use Normalized Tables and SUMIFS to Calculate Available Stock
The most robust way to track inventory is by separating starting stock, customer orders, and calculated current stock into distinct, normalized tables and using the SUMIFS function.
By structuring your workbook into separated tables, you ensure that manual data entry does not interfere with dynamic formulas. This method relies on exact matches for product variations to maintain accurate inventory counts.
Create a 'Starting Inventory' table with columns for product type, brand, color, size, category, and the initial stock quantity for each unique combination.
Create a separate 'Customer Orders' table containing the exact same identifying columns (brand, color, size, etc.) plus an 'Ordered Quantity' column for new entries.
Create a 'Current Stock' summary table containing a single row for every unique product combination.
In the 'Current Stock' table, use the SUMIFS function to sum the 'Ordered Quantity' from the Customer Orders table, setting the criteria to match the specific brand, color, size, and category.
Subtract the SUMIFS result from your starting inventory quantity to display the real-time available stock that updates automatically as new orders are added.
Start with a Built-in Inventory Tracking Template
If you prefer not to build formulas from scratch, you can modify an existing inventory template to suit your specific product attributes.
Create Dynamic Inventory Trackers with WPS Spreadsheet
WPS Spreadsheet provides powerful data processing tools, including dynamic arrays, PivotTables, and advanced formulas like SUMIFS, making it easy to build automated inventory trackers from scratch or customize built-in templates.
- 1. Launch WPS Spreadsheet: Open WPS Office and launch the Spreadsheet application to start a new blank workbook or search the template library for 'Inventory'.
- 2. Structure Your Tables: Create dedicated sheets for 'Starting Stock' and 'Customer Orders', ensuring you have columns for brand, color, size, and category.
- 3. Apply Formulas: Use the built-in formula builder to insert the SUMIFS function, linking your order quantities to your starting stock for automatic deductions.
Frequently Asked Questions
Why should I keep order entry and inventory tables separate?
Keeping your starting stock, order entries, and calculated stock in separate tables prevents circular references and data corruption. It ensures that manual data entry, such as logging new customer orders, does not overwrite the dynamic formulas used to calculate the current stock.
Can I use a PivotTable instead of SUMIFS to track inventory?
Yes. You can consolidate all transactions into a single master log—recording starting stock as positive numbers and customer orders as negative numbers. You can then insert a PivotTable to summarize the current stock level by grouping the items by brand, color, size, and category.
What does it mean to have a 'normalized' inventory table?
A normalized inventory table means organizing your data so that each unique combination of product attributes (e.g., brand, color, size, category) has exactly one row. This eliminates duplicate entries and guarantees that conditional formulas like SUMIFS accurately aggregate the data.
