Vendor / Supplier

Vendors rarely invoice with 100% accuracy. Errors can arise simply from mispostings or from misinterpretation of complex contractual agreements. In today’s business environment where internal staff are challenged to review and process invoices on time, it is critical to have outside expertise available to identify and recover lost profits. A comprehensive AMS-PAR vendor review program will determine the current level of contract compliance of key suppliers without adding additional burden to the your staff. We will examine the agreements that are the basis for the commercial relationship, verify that the resulting invoice activity complies with the terms of those agreements and confirm that payments made under the agreements are accurate. AMS-PAR will also assess the vendor’s compliance with the client’s business ethics policy.

Our reports not only provide sufficient detail to facilitate collection, but they also include specific recommendations for improving contracting procedures and contract management processes to ensure that errors do not recur. With your concurrence, we also recover overpayments.
