Congratulations on your new business, @wahabtawab400.
There are a lot of good options for laptops or desktop computers you can use to get the best QuickBooks Desktop (QBDT) experience. The DELL XPS 13 is also a good choice of computer hardware. However, it'll be up to you to decide which is the best one to use.
You just need to make sure the laptop or desktop computer meets the minimum system requirements for the QBDT program. This will ensure the system is compatible with your setup and help avoid any possible issues when installing and using it in the future.
Depending on the version of the QBDT program you want to install on your computer, you can refer to this article about the operating system, hardware, software, and other requirements to run QBDT: System requirements for QuickBooks Desktop 2021.
Please know that you're always welcome to comment below if you have other concerns or follow-up inquiries about system requirements and managing your business using QBDT. I'm just around to help. Take care.
