Employee and supplier accounts don't show Cost Rate/hr, only billable rate, why? on my other QB account they're exist, how can i add them?

Let's why this is happening, Kay84.

You might have not marked the Show Items table for expenses in your Account and Settings. Here's how:

1. Click the Gear icon in the upper-right corner and select Account and Settings.
2. Select the Expenses tab and go to the Bills and expenses section.
3. Mark the Show Items table on expense and purchase forms box.
4. Click Save and Done.

That should allow you to see the costs of the billable items. Also, I'd recommend reviewing the affected items. Then, ensure that the costs were already added. Here's how:

1. Click the Gear icon in the upper-right corner and select Products and services.
2. Look for the item and click Edit.
3. In the Product/Service information window, scroll-down to the Purchasing information section.
4. Make sure the I purchase this product/service from a vendor box is marked.
5. Enter the Cost and the Expense account.
6. Click Save and close.
