Create a Payment Request for the amount you want to pay. This will go through the approval process and pay based on the supplier payment terms.  If the deposit payment needs to be accelerated, then during the checkout process, navigate to Special Handling & AP and edit the check delivery to: Mail to Supplier. By changing this field, AP will be made aware that payment needs special handling.

If the deposit needs to be applied to a PO: Create a PO for the full amount. Email the deposit form (referencing the PO #) and the invoice (if available) to: AP_Invoices@harvard.edu. Indicate on the Deposit form any special handling.
