I started using quickbooks online for 2019. I want to set up a new comany for 2020 as I now have a better understanding of everything and don't like how I set up 2019.
I'm glad to have you as a member of the QuickBooks Online family. I can appreciate needing to set up your books in a different way now that you're more familiar with the program and I want to make sure you have the tools and know-how to start a new QuickBooks Online account and get going on the right foot.
It's absolutely possible to set up a new QuickBooks Online account using the same login credentials of your existing account, just as Fiat Lux mentioned. I wanted to chime in to share an article we have that can help you with that process if that's the route you choose to go with creating a new QuickBooks Online: Create a new company and add subscriptions. Keep in mind that QuickBooks Online works on a one account per subscription basis, meaning each subscription only holds one set of data.
You can explore the third-party options that Fiat Lux brings up, but keep in mind how these might affect the setup you have in place. If you're only looking to bring over certain data from the old QuickBooks Online company, You can learn what export and import options are built into QuickBooks Online by going to the Gear icon in your account and choosing Import Data or Export Data.
Once you're all set up in the new QuickBooks Online account, don't forget to cancel the old account if you're not longer going to use it. Doing this will ensure that you're not getting double charged. Learn how to do that here: Cancel your QuickBooks Online subscription
