What causes a sales receipt not to show the total cost?

Hi Frank, I'm glad you posted here in the Community forum. Let me share a few things about the sales receipt not showing the cost of its item in QuickBooks Online (QBO).

If you're referring to the cost of the item you purchased, it won't appear on the sales receipt since it is a sales transaction. Only the sales price/amount will appear on the item that you will sell. However, if you are referring to the sales price/amount that didn't show in your sales receipt, the most common cause for it is due to corrupted cache files in your browser. 

To rectify this, you can access your QBO account using a private or incognito window. If it's working, go back to your regular browser and clear its cache. Otherwise, use other supported web engines to learn what computer and browser are needed for the best experience when using QuickBooks.

Another common cause is not selecting the correct form template when creating your sales receipt. To ensure you're selecting the right one, click on Customize at the bottom of the sales transaction page. Then select your template. 

Also, I recommend reviewing your template to check if the amount column is enabled. To do this, go to the Gear icon > Custom form styles > Choose the template then click on Edit. See the screenshot below for your visual guide.
