Vendor / Supplier

Given the steady rise in maintenance, fuel, and feedstock costs, it is increasingly important for refinery and petrochemical companies to carefully monitor and control their contractual relationships. Most of these companies have seen significant increases in spending, but few are adding staff to track and control these increasing costs. As the spending grows, so does the need to have contracts analyzed for compliance with their terms and conditions. In today’s multi-million dollar contract environment, even small interpretational errors by a vendor can create large overpayments. Agreements that in the past were too small to warrant review are now substantial enough to receive attention.

For over 25 years, AMS-PAR and its staff have helped refining and petrochemical companies monitor their costs. A comprehensive AMS-PAR vendor review program will determine the current level of contract compliance of key suppliers without adding additional burden to existing staff. We will examine the agreements which are the basis for the refinery and petrochemical facility’s commercial relationships, verify that the resulting invoice activity complies with the terms of the agreements and confirm that payments made under the agreements are accurate. AMS-PAR will also assess compliance with your business ethics policy. Our reports provide sufficient detail to facilitate collection of erroneous payments. We also make specific recommendations to improve contracting procedures and contract management processes to ensure that these errors do not recur.

AMS-PAR conducts a wide variety of reviews for the refining and petrochemical business sector. Common types of compliance reviews include:
  • Material suppliers
  • Service suppliers
  • Turnaround services
  • Engineering and environmental service providers
  • Construction contractors
  • Business ethics
