Great to have you here, toddshoemaker.

QuickBooks Desktop hides markups from the customer by printing only the price or rate after the markup. If you want your customers to see the markup, just customize your estimates so that the original cost and markup appear when printing your estimates. Just follow the steps below:

1. Go to Lists on the top menu.
2. Choose Templates.
3. Select template for Estimate, 
4. Tap the Additional Customization button. Then, tick the Columns tab.
5. In the Markup row, select the Print check box.
6. Enter a name for the template and press OK.

If you want to hide the Markup column when printing and from your customer, just choose the Screen option only. Just go back to the Columns tab in the Additional Customization page. 

On the other hand, QuickBooks Desktop has a default markup percentage. Where it uses this percentage to calculate the sales price of items that have both a cost and a sales price. If you'll want to hide MarkUp on Invoice, just select the "Print selected time and costs as invoice item" at the bottom. See attached screenshot below for reference.

However, you can't edit the markup percentage when creating an invoice. I've added these articles for additional reference. It provides steps on how to manage your templates in QuickBooks:

• Import custom form styles for invoices or estimates
