A European company I have been consulting to asked seven of its major European law firms to submit bills electronically. The law department asked for them to comply with the standard LEDES 98b format.
Four or five of the law firms demurred. They responded that they could not report from their time and billing systems the data in the LEDES form. Before this recent experience, it had been my supposition that all law firms with a time and billing system can generate the requisite easy-to-format files. Perhaps the reluctance of these firms stemmed from something other than technical inability.
