AR vs statement of account contact - difference and use case - SOA contact update to existing invoices and calculated SOAs

QUESTION: Is there a reason when we update a client/matter contact and flag them as the Accounts receivable contact that they are not automatically the person who appears on the Statement of Account? Where can you execute this change to update the statement of account at the same time without using the SOA module?  I updated a client contact but in the SOA module the contact was still the old person?

RESPONSE: Whereas the “AR Contact” is the final authority if there is an issue with the client’s ability to meet its financial commitments, when the statement of account recipient is not the billing contact for a client and all its matters and/or someone else for specific matters, highlight the client or matter level party represented intended to receive the SOA and select “Flag as Statement of Account Contact”. This will set the contact as the SOA recipient.
