Validate Accurate Payment for Your Supplier Services

Manual invoice validation is often slow, error-prone, and lacks capacity. Complex contracts lead to missed discounts, overcharges and wasted spend. Contractual agreements contain significant financial details beyond what companies may validate within the fees section of invoices.  Current validation processes may be incomplete or require standardization. ISG finds most enterprises are unknowingly overpaying suppliers by 3-10%.

Using ISG’s years of procurement and supplier expertise, we meticulously analyze historical invoices to uncover discrepancies and excess charges. ISG’s proven methodology and decades of negotiating and managing contracts drives higher validation accuracy using a 4-way data match. We also work with our clients to build a proactive vendor management organization to drive maturity and prevent future errors.

We deliver real outcomes: recovered spend, improved accuracy and streamlined vendor relationships.
