I strongly believe any decision making process privileges that one can grant to employees can be very beneficial as stated above in the example. This shows trust in employees, and I believe giving employees extra responsibilities can have a very positive effect. In a group decision making environment, this also promotes team work. Having a department making decisions together is a great way to encourage this.
I believe this is something the whole organisation should be aware of, this way any client facing employees can better explain this to customers/clients in the event questions or queries are raised. Stakeholders would include clients/ customers so I believe a communication in the form of a letter/ email should be sent out to all client base explaining how the new payment process work and how it will benefit them. The most important part is to promote it as a positive change for the client/customers.
