Utilising "Payment Methods" can be another way of ensuring that Sales Orders are not credit held. 

Via the Search function in Business Central, type "Payment Methods". Here, the available payment methods can be setup. Notice that now Clever Credit is installed, there is a new field called Exclude from Credit Hold. Where this is 'Yes', any Customer using this Payment Method Code on a "Sales Order" will be excluded from having their documents held if they exceed the credit limit or have an Overdue balance.
