Hello Romi,
Thanks for the details of what you're hoping to achieve in QuickBooks Desktop Enterprise. It's important to me that you're able to get a solid answer one way or the other about what you're looking to do, so it may be worth a call in to explain in more detail what you're looking for.
Based on what you've described here, it sounds like you may be looking at creating assembly items. Assembly items are products and services that are made up of other products and services in your system. Take a look at the Item Types drop down in the follow article to learn more: Add, edit, and delete items
As an Enterprise user, you can also take a look at the Advanced Inventory add on to see if the option you're looking for is available. Learn about that feature here: Set up Advanced Inventory
One of the awesome things about QuickBooks Enterprise is support costs are included in your subscription rate. Here's how you can get in touch: dial 1-877-772-9158 from Monday to Friday between 9 a.m. and 8 p.m. ET. Follow the prompts for QuickBooks Desktop and choose Enterprise to connect with an Enterprise agent.
I hope that helps!
