When you receive the check from your Client as the advance for a vendor payment, deposit it in your Operating Account and enter it in Orion as a Retainer Deposit (RDP).  Once the Retainer Balance is established, go into AP Manager, enter a Voucher on the Operating Account payable to the correct Vendor.  Distribute the Voucher to the Client-Matter and use the RDS code.  Pay the Voucher.

NOTE: Based on your Firm’s procedures, you may wish to treat this advance payment as trust rather than retainer.  The procedures to follow are the same except you deposit the check in your Trust account and enter it in Orion as a Trust Deposit (TDP).  The Voucher will be created and written on the Trust account and distributed to the Client as a TDS.
