How can I set the sales price of a bundle as there does not seem to be this option in the setup?

The price of a bundle is the total price of all its items, peter25.

For now, there's no option to enter the sales price when creating a bundle. You'll need to edit the item and enter the amount on each one of them. Here's how:

1. Select an item that is part of the bundle, then click Edit under the Action column.
2. Scroll-down and look for the Sales price/rate field.
3. Enter the amount and click Save and close.

Once done, QuickBooks will automatically use the total sales price whenever the bundle is used in invoices or sales receipt.
