Auditing your telecom expenses is the first step to understanding how to control your company’s communications costs. According to analysts, 85% of the telecom invoices customers receive from vendors have billing errors, costing organizations up to 12% of their annual telecom expenses in inflated costs.

Working with the vendors to negotiate refunds for overbilling is often a very long and drawn-out process. In our experience, organizations that perform their own telecom audits can expect to cut expenses by 3-5% provided they have the learned knowledge, expertise, enough resources focused on the task, access to their provider tariffs, and effective negotiation skills to recover money from carriers. Through CDP’s experienced Professional Services team, organizations that take advantage of our Telecom Auditing service often experience reductions in excess of 25-40% of their annualized telecom expense.
