Hi Pro Grade Enterprises Inc,

We want to help you with your concern about reactivating clients. However, we need more information to provide the correct resolution and sort this out promptly.

Did you filter the list to show inactive clients? Are they not showing on the list? If you could provide some screenshots, it would greatly help.

In the meantime, you can check this article for additional guidance on exporting reports like customer lists in QuickBooks: Export reports as Excel workbooks in QuickBooks Desktop.

Please know that you're always welcome to post questions in this space. Have a great day ahead.
