CASH Tool
Cash Application tool allows the linkage and relationship to be reestablished between invoice number sent to customer and the group of invoices from LeasePak. Thus it helps to avoid the research and determination of which LeasePack invoices to apply the cash manually. Cash is received from the customer is in three forms; an image of check received into lockbox, direct wires and ACH. Cash Application tool receives EDI file for all checks that go through the BoFA lockbox. It Validates the EDI file, the exceptions will be corrected and the payments will be applied to referenced customer invoice(s) that is then linked to the related LP invoices. Payment is then applied to the LeasePak invoice on nightly basis. Cash Application interface would be used for wire and ACH payments and manually executed exceptions. Besides transaction process, the Cash Application interface allows to generate reports with respect to check information, invoice information, batch information and EDI exceptions.

There are several internal systems that currently perform the business functions to serve Prosumer and Enterprise users. The Business Life System called as BLiS is a main system which maintains the Prosumer account, product and service SKUs, credit card charging and settlement. BLiS provides SOAP interface for all its Prosumer APIs. These APIs can be used by other internal systems within WebEx to integrate and build an application with necessary business logic and validation. Web applications are typical client applications that are built using these APIs. Also, a key aspect to mention of BLiS and the interfaces exposed is that they are stateless. It is the responsibility of the client application to implement appropriate state / session functionality on behalf of the end users.
Knowledge Base contains a rich collection of articles are made available on the kb.webex.com site to help end users of WebEx products and services. This site provides anonymous access to these articles that are meant for end users. The articles are typically textual in nature and occasionally contain references to documents which may be flash or PDF files.
