--Cross posted-- I have a client asking about putting a Sales Order on hold and I am not sure the best answer. In this situation the SO have been Approved by accounting and cleared for shipping... The status is Pending Fulfillment. Then, for a few different possible reasons, they want to 'pause' the shipment pending some other unspecified event. They have asked about a new status but I dont think that is even possible, and if it was I would not like to do that. So my question to you is, how to HOLD an Pending Fulfillment Sales Order? I know I could just put a check box on the form and they MAY be what I do but I wanted to see if there are other ideas?

One native option you might consider is putting the customer on a credit hold and then setting your accounting preferences to enforce holds. Maybe doesn't work for your particular scenario (e.g. if you want to allow other transactions to process for that customer or if you don't want to enforce credit holds for other customers) but it is a potential solution that doesn't require any custom stuff (and just two dropdown selections to implement).

I am way late to this convo @Sean Murphy but I'd probably just add a checkbox to the sales order, and then on the fulfillment transaction, return a user error if that box is checked on the SO.
