Can you deactivate several customers at one time

Hello there, @ecotecinsulation.

Yes, you can deactivate several customers at one time in QuickBooks Online (QBO). Let's utilize the Batch actions feature in the Customers tab to do this and help you manage your customer list accordingly.

QuickBooks make sure you can easily manage your customer list. Before doing so, please know that even if a customer is inactive, all their transactions will still be available on reports. To deactivate multiple customers, follow these steps:

1. Go to ​Get paid & pay or the Sales menu, then Customers.
2. Select the boxes beside the customers' names of all the ones you want to deactivate.
3. Click the Batch actions dropdown ▼.
4. Select Make inactive, then Yes to confirm. 

Once you're done, there should be a "(deleted)" statement indicated beside the name of all your deactivated customers.
