I tick wrongly for suppliers make inactive , how i reactive back the suppliers?

Hello, catherinelim. 

Thank you for reaching out to the Community. Reactivating your supplier is super easy, I'll be here to guide you on how to do it:  

1. Go to the Expenses menu and select Suppliers.
2. Above the Action column, click the Gear icon, then check the Include inactive. 

I've added an article for you to check. This will show you how to change some info on your supplier's profile: How to edit, delete, and restore list elements. 

That's it. Now you have your inactive supplier back to active. Let me know if there's anything else I can help with. I'm just a post away. Take care!
