About Us

  • Andy was hired to work as Global Project Manager for our Concur T&E implementation during 18 months for rolling out 12 countries which covered 6 different languages. His excellent ability to project manage, communicate and understand the cultural needs across our cross functional teams which included Purchasing, AP, IT and Finance made for great success and exceeded our expectations
    We needed a professional who had both Finance and IT/SAAS System proficiency. Additionally, Andy’s wide range of language skills plus working with multinational companies made him the best candidate.
    ​I would highly recommend Andy and his team to any company looking to roll out Concur.
  • ​We engaged Andy to work on a project for one of our multinational end-user clients deploying Concur. We have had nothing but extremely positive feedback for his work - they say Andy is a true subject matter expert in Concur in addition to having excellent business facing consulting and project management skills.
