What Is Managing Inventory With Excel?

Inventory management involves utilizing Excel spreadsheets to track and manage inventory sourcing, storage, and sale. This is implemented so that inventory managers and staff may utilize and update documentation throughout the business and supply chain. Businesses may have a better understanding of product performance and areas where the inventory management process can be improved by doing so.

How To Manage Inventory With Excel? Create Your Own Template

Before you can utilize Excel spreadsheets, you must first become familiar with the program and learn how to organize your inventory using category columns and manual product entry. In this part, we’ll explain to you how to manage inventory in excel in-depth with two main tasks:

  • Create an inventory in and out table and update both with your inventory movements
  • Calculate inventory valuations

Now, let’s start!

Step 1: Create a spreadsheet

Create a new spreadsheet in Microsoft Excel to manage your inventory. Select New from the menu in Excel. To start a new Excel sheet, click the Blank workbook or press Ctrl + N. Then, navigate to the spreadsheet work area and fill in your details.

Step 2: Determine what to track

The key to making the most of Excel as an inventory management tool in determining which details to track and which categories to use to organize your data. Here are some examples of items to keep track of:

  • Description
  • Barcode or QR code numbers
  • SKU
  • Location
  • Bin number
  • Units
  • Quantity
  • Reorder quantity
  • Cost
  • Inventory value
  • Reorder flag

Step 3: Fill in your Inventory list

You can create an inventory listing for your items as well as a plan for inventory movement. Each product you sell may be entered into the relevant category column. It's up to you how specific you want to be, but including the product name, quantity, cost of the product, and code or SKU is undoubtedly beneficial. The following table is an example of an inventory list.

Step 4: Create Inventory Movement Schedule

Create a new table of Inventory In & Out Schedule in the same spreadsheet with your inventory list like the image below. 

Inventory-Movement-Schedule
 Inventory Movement Schedule
  • Define Type of Movement

In ‘In & Out Schedule’ table, we need to define the Type of Movement we want valid entries to be either Sales Receipts or Adjustments. You need to create a new small table of these three types of movement. Then, define that table with the new name Select table > ‘Formulas’ > ‘Define Name’ > Type the name field of the table you want to define. 

Define-the-name-of-your-table-min
Define the name of your table

Next, we need to enter a drop-down box in cell I4. With the I4 selected, choose the data ribbon > Data validation tool.

In the allow box below, select ‘List’. In the source field, enter “=TYPE” (the table name of types of movements that you’ve defined before).

Enter the source field into the drop-down box

Now you can select three options from the type lists.

Drag and copy the formula on cell I4 down to the last cell in the column. So all the rows for the type column contain the type list dropdown box.

  • Define The Code

Similar to part 1 above, first you need to define the code column in the table ‘Inventory list’ with the new name ‘CODE’. Next, create a drop-down box on cell J4 and copy the formula down to the last cell.

Step 5: Fill in the details of the movements

Now you can start checking your inventory with the very first phase. You need to fill in the ‘In & Out Schedule’ with Date, Type, and Code first, then Product Name, Qty, Cost, and Value.

  • Product name

With the product name, we have the formula to double-check it following its code. First, define the ‘Inventory List’ table with the new name ‘DETAIL’, then the ‘In & Out Schedule’ table will populate with the value from the ‘DETAIL’ tables. 

Define-Inventory-List-to-DETAILS
Define Inventory List to DETAILS

Use Vlookup function with the following formula to find the product name from ‘Inventory List’: =VLOOKUP(J4,DETAIL,2,FALSE) 

Find-the-product-name-by-Vlookup
 Find the product name by Vlookup
  • Cost

Similarly to the Cost, use the Vlookup function with the following formula to find the Cost from ‘Inventory List’: =VLOOKUP(J4,DETAIL,3,FALSE)

Find-the-Cost-by-Vlookup
 Find the Cost by Vlookup
  • Value

Now. let’s complete the first line with the Qty of 15 in cell M4. The value in cell N4 is simply the quantity in M4 multiplied by the cost in I4. In other words, Value = Qty*Cost 

Calculate-the-value
 Calculate the value

Note: In order not to receive an error message in the cells Product, Cost, Value (which totally depend on Code) when Code is invalid. You need to add some elements on Vlookup formulas on Product, and Cost cells. =IF(J4="","",VLOOKUP(J4,DETAIL,2,FALSE)) =IF(J4="","",VLOOKUP(J4,DETAIL,3,FALSE)) =IF(J4="","",+M4*L4) That’s most of the work done in the ‘Inventory In & Out Schedule’ table. Next, you need to add a couple of totals for Qty and Value and change the number formatting.

  • Selecting both Qty and Value column > Right-click your mouse > Format cells > Number Category. Set to two decimal places and set the negative number to be in red.
Change-the-number-formatting
Change the number formatting
  • Do the same to Qty column except set the decimals to zero
Change-the-number-formatting (2)
Change the number formatting
  • Subtotal

Enter these two formulas at the end of the Qty and Value column to count the total: =SUBTOTAL(9,M4:M18) =SUBTOTAL(9,N4:N18) Then, create a Filter for ‘In & Out’ table. 

Count-the-total
Count the total

After step 5, you will get full of ‘In & Out’ Schedule like this:

Full-of-‘In-&-Out’-Schedule-table

Step 6: Calculate the running or the cumulative totals for each product

We’ve arrived at the final step! After one week of working, we’ve recorded the inventory movements like step 5. Now it’s time to summarize the running or the cumulative totals for each product. Let’s return to ‘Inventory List’ and enter the formula to automatically calculate the running or the cumulative totals for each product together with a valuation for each product line. To do this, we use the SUMIF command which will add up both the positive and negative values for each product based on the movements in the inventory. To easily use the SUMIF command, it’s better to name the range we will use: Code and Qty. We will define these two ranges as INOUTCODE and INOUTQTY. 

Define-INOUTCODE
Define INOUTCODE

Now, enter the formulas: =SUMIF(INOUTCODE,B4,INOUTQTY)

Define-INOUTQTY
INOUTQTY

Define T-shirt White has the quantity of 53 which is a cumulative total. The Value = Qty*Cost 

Count qty-and-value
 Count qty and value

Drag Qty and Value down to the last cell and create a Sum at the end of the Value column. The final result will be like this: 

Final-result
 Final result

Note: Remember to make sure the 0 value not be displayed. Now you’ve already known how to manage stock in Excel. However, even after you've entered all of the relevant product data, you'll still need to keep track of your spreadsheet on a regular basis. Because Excel is a static system (i.e., it lacks automation and integrations), you'll need to go to it regularly and modify your different inventory levels when sales and product movements occur. Keeping track of your inventory counts is critical, as neglecting to do so can cause delays in your supply chain and a variety of inventory problems.
