I made an account inactive by mistake - how do i activate that account.

Hello useretinney,

Thanks for connecting with us here in the Community. QuickBooks offers the flexibility you need to automate your accounting with ease. I'll be happy to show you how to activate the account again so you can get back to doing what you love. 

Here are the steps to follow:

1. Go to Settings ⚙, then select Chart of accounts.
2. Select the Gear icon ⚙ next to the printer icon. Then select Include inactive.
3. Find the account you want to use again, then select Make active.

It's important to not that, QuickBooks won't add transactions back to the account or edit any journal entries it made to balance your accounts.

Give this a try and let me know how you make out. I'll be a message away in case you need anything else.
