Could you set up a custom field for Send Yes/No and then run the bills in separate batches for each selection?

Take a look at client custom fields if you don't already use them. Setup a list type custom field called "bill hold" with yes or no values as choices and make it required so you can't save a new client without providing that value. Then you can process bills filtering for your normal date range as well as whether the clients are "held" or not. You could still use the charges on hold analysis report filtering in the same manner but when you approve bills that are "held" and not sent to clients you are booking A/R that the client has not seen yet. Hope this helps!

Thank you, Marc. I will look into setting up a custom field. I appreciate your response!

Thank you, Allen. As booking A/R was the reason for taking the clients off hold, I will certainly try this. I appreciate your help!
