Hello there, Darth.
Allow me to share some information with regard to accessing your company file on your office workstation at home.
Accessing your company file in a multi-user environment allows multiple users to access the file simultaneously in the same place. A multi-user network on the other hand allows you to access QBDT remotely from a host or server.
Since you want to access your company file on your office workstation at home, you'll need to use Network when setting up multi-user mode and yes, @Fiat is right that you'll need a third-party hosting provider to access QBDT securely anytime, anywhere.
While there are companies that are authorized to host QuickBooks, Intuit doesn't endorse, certify, sponsor, or guarantee the hosts' services. With this, I'll be giving you this article for you to choose one of these authorized providers: Hosting providers authorized by Intuit.
I've also added this article that'll serve as your reference on what tasks you can perform using a multi-user mode: Features available and tasks you can perform in single or multi-user mode.
I'll be right here if you've got additional queries with regard to managing and accessing your company file in QBDT. Take care and have a great day!
