The management of the bill of sale process is handled comprehensively by the LeaseWave® AP lease accounting software system. This is done in conjunction with the vendor management functionality through the workflow management module, allowing the association of a given bill with its relevant vendor and leasing customer. In some businesses, the clearance of a lien given by the vendor or equipment supplier is a vital component of the overall lease transaction. The bill of sale allows the lessor unencumbered ownership to the assets in question. It can also drive certain decisions made on a given lease application, including remarketing of assets when they are returned from the lease.
