# What if I need to build more than one System on one job?
If the job you're assessing / proposal you're building requires more than one system, *once you've completed one system and have reached the [**final page of the fastquote**](https://helpcenter.unicosystem.com/knowledge/finalizing-a-fastquote?hsLang=en)*, you can hit "**add system**".
From here, you'll be walked through each step of the guide once more. Don't worry, ***your material list from the first system will stay saved*** as you build additional systems for this proposal.
Once your additional system has been created, you can toggle over to it at the top of your page
By toggling to each system, you'll see the list of ***core system products for that system*** on the right side of the page, for example:
Once you've built both systems in the app, the [**material list**](https://helpcenter.unicosystem.com/knowledge/how-do-i-build-a-material-list?hsLang=en) of line items found on the summary page includes all materials of ***all systems***:
Your **quote/price created** will be for ***all systems*** within that proposal.
