How can I put an invoice on hold? Or, a customer on hold?

Let me help with your question about putting the customer on hold, proper.alexis.

You can temporary make the customer inactive in your QBO account. Here's how:

1. Go to the Sales menu and proceed to the Customers tab.
2. Look for the name of the customer and click on it.
3. Click the Edit button in the upper-right hand corner.
4. Select Make inactive.
5. Click Yes.

To make the customer active again, you can go back to the same page and click the Make Active button in the upper-right hand corner. Here's an article about this for more details: Add and Manage Customers in QuickBooks Online.

However, there's no option to do the same for invoices. You'll want to delete or void them instead. Check out this article as a guide: Void or Delete Transactions in QuickBooks Online.

Feel free to watch this video tutorial just in case you want to do the same for your vendors: How to Manage Your Vendors List.

This is not a good option.  Customer Service should be able to see that the account is on credit hold, so that they can notify the customer and ask them to contact accounting.  By simply making the customer inactive, could trigger someone with access to be able to reactivate.  It would be best if QuickBooks came up with an option to put the customer on credit hold so that everyone from customer service to production and shipping can see that and not process any orders without having hte release from the credit department.

There are many other softwares that offer this as an option.
