A pro forma invoice is the same as a commercial invoice which, when used in international trade, represents the details of an international sale to customs authorities.
TRID requires process changes to the loan origination life-cycle, particularly in the way that lenders approach the closing of loans. Under the new rule, the closing process needs to be at least three days ahead to meet the Closing Disclosure timing requirement.
The new rules (TILA RESPA Integrated Disclosure or TRID, if you really want to know) were completed two years ago, and the final date for implementation was even delayed three more months to make sure lenders could comply. At the heart of it are two forms, one providing the loan estimate and one the closing disclosure.
