The preliminary file checks that take place in Corridor are:
LEDES 1998B, 1998BI/1998BI V2, and LEDES 2000 (if submitting a LEDES formatted invoice file)
Client's Matter Number
Vendor's Tax ID Number (matches Tax ID in Corridor)
Client ID (matches Client ID in Corridor)
Invoice Number
Invoice Total
Invoice Date
In addition, Corridor validates the Client ID field in the invoice file against the Client ID field in Corridor for the receiving client company. If these do not match, Corridor will return an error message.
Further
validation occurs once the invoice reaches the matter management application.
For example, the file may pass initial checks because a value is entered
in the Client Matter Number field, but may be rejected once it reaches
the matter management application because the client matter number does
not exist in eCounsel or LawManager. Additionally, eCounsel will reject
an invoice that does not have a unique Invoice Number.
