Does a Voucher have to be Paid before the Client-Matter File is Updated?

The writing or voiding of a check has no effect on Client-Matter files.  The posting/adjusting/voiding of the voucher is what modifies these files.  As soon as a Voucher is posted, Client Advances created by the voucher are saved on the Client-Matter file.  Any RDS, TDS or TAP transactions are also saved on the file and the relevant retainer or trust balances are reduced.  Client Advances can be billed to and paid by a Client-Matter before the vendor is ever paid.
