LEDES file formats

LEDES, pronounced Leeds, stands for Legal Electronic Data Exchange Standard. It's a standardized invoice file format in the legal industry and was created for the electronic exchange of billing and other information between corporations and law firms.
You can post invoices in any of these formats.

Types of billing formats

  • LEDES 1998B: A pipe delimited format containing 24 fields. It's the most-widely used e-billing standard in the US legal industry.
  • LEDES 1998BI: Builds on from the 1998B version to allow for international billing. It includes 51 fields to allow more information such as timekeeper classifications, tax rate, and law firm and client addresses.
  • LEDES XML: Contains more than LEDES 1998B and is made more robust to accommodate the complexity of fee arrangements between corporations and law firms.
