Contract Compliance

QuisLex assists clients in developing and implementing contract and regulatory compliance programs across a wide spectrum of areas. Our work includes remediation efforts to bring existing contracts into compliance and designing programs to help ensure new contracts will meet both regulatory and internal compliance standards.

Our compliance work, which is often performed in conjunction with broader contract management workflow design and ongoing contract lifecycle management, has been recognized by the International Association of Commercial and Contract Management (IACCM), which selected QuisLex as its Outstanding Service Provider for our work in this area.

M&A Contract Due Diligence

QuisLex has extensive experience supporting organizations, many operating globally, with pre- and post-transaction contract due diligence for M&A, spin-offs, and corporate restructurings.

Companies active in M&A often need to complete contract due diligence under significant time constraints and frequently for multiple targets simultaneously. Resource constraints may make it impractical to do this internally, and the costs of engaging a law firm for the heavy lifting can be significant. QuisLex provides an alternative solution that effectively manages risk without incurring outsized costs allowing companies to:

  1. Increase ROI for deals that close
  2. Mitigate bottom line impact of unconsummated deals
  3. Consider a wider range of targets than they might have leveraging the more favorable transactional cost structure, and

Incorporate post-transaction integration considerations into the due diligence process to streamline the integration process and reduce integration risk. Learn more.

Open Source Compliance

QuisLex has a broad range of experience enabling our clients to fully realize the benefits of open source software licensing while managing for the associated risks. We have developed a detailed set of best practices for supporting open source initiatives and ensuring necessary compliance.

As a result, clients are better able to identify and manage risks associated with open source software use, facilitate compliance with license requirements, and produce a permanent record of open source software use.

Our support functions include:

  • Client and third party open source use review to identify risks and help ensure license compliance
  • Draft compliance obligations and identify license incompatibilities
  • Provide an open source text file for distribution with product
  • Analyze open source obligations and risks for M&A due diligence
  • Create and maintain a permanent record of open source software use.Learn more.

Legal Spend Management

QuisLex’s Legal Spend Management services help legal departments understand, control, and better leverage their spend. QuisLex has expertise in designing and implementing legal spend management programs to not only identify non-compliant charges through invoice review, but also to provide the support analyses needed to continually improve your legal spend profile.

Through accurate legal spend data collection, analysis and benchmarking, legal departments can control costs and gain better budget predictability while continuing to focus on their main goal: legal and business outcomes.

Accurate and consistent data is essential to meaningful key performance indicators, understanding return on investment and calculating total cost of legal spend to answer the question: “Where does my legal spend go?” Learn more.
