I'm happy to know that you're interested in using QuickBooks Enterprise. I can provide some insight about setting up inventory in this version that I'm sure you'll find helpful.
Yes, you can add these doors at 24 square foot each. To do this, we'll need to activate the Unit of Measure feature first, let me walk you through the steps on how to do it:
From the Edit menu, choose Preferences.
In the left navigation menu, select Items & Inventory.
Go to the CompanyPreferences tab.
In the Unit of Measure section, click Enable.
Select Multiple U/M Per Item.
Next, we'll need to create the item (door) with the correct setup to ensure QuickBooks will calculate the right amount when you enter it on an invoice. The following steps will guide you through the process.
To create the inventory item:
From the Lists menu, choose Item List.
Click the Item drop-down menu at the lower left corner of the page.
From the Type drop-down menu, choose Inventory Part.
Name this item.
Enter the Cost and SalesPrice of this item.
From the Income Account drop-down menu, make sure to select the right account.
To set up the unit of measure for this item:
Still on the Item List page, double-click the item you just created.
Click the U/M Set drop-down menu, then select Add New.
In the Unitof Measure window, here's what you need to do on the corresponding pages: - Select a Unit of Measure Type: Choose Area (square foot, acre, square meter, etc.), then click Next. - Select a Base Unit of Measure: Select Square foot (sqft), then click Next. - Skip the Add Related Units page by clicking Next.
Enter a Set Name, then hit Finish.
Click the Edit button.
In the Related Units section, enter the appropriate details on each field. I've attached a screenshot to show you an example.
