How to work with linked computers

Hello Abacus2,

Welcome to the Community. I'll be glad to guide you in the right direction so you're on the right track. 

QuickBooks Desktop allows you to use multiple computers on the same network. This process is called hosting and I encourage you to learn more about this using the following article: Host your company data in multi-user mode in QuickBooks Desktop. When you say update, are you referring to the subscription? 

Feel free to get back to me in the comments below. I'll be here.

Make sure you have a QB Desktop license for 2 users or more. You can't use 2 licenses for single user to work.
