Kasowitz has established the country’s foremost practice devoted to representing companies and public entities in the recovery of damages arising out of failed and problematic implementations of enterprise resource planning (ERP) business software.  Few corporate initiatives are as fraught with risk as these high-priced projects, which often deliver a new software platform that is scarcely better than the legacy system it replaced.  Even worse are ERP catastrophes – mission-critical projects that fail upon go-live, decimating customer relationships, financial results, growth and acquisition plans, investors’ and lenders’ confidence and employee morale.  Many companies that have faced the business disruption and chaos stemming from an oversold and improperly designed and implemented ERP rollout have turned to our attorneys to obtain compensation from the responsible consulting or software firms.
