Choosing the right telecom expense management services partner can mean the difference between recovering 25-35% of your annual spend and continuing to pay for services nobody uses.

The onboarding period sets the tone for your entire TEM relationship. You want a partner that begins processing your invoices quickly, not one that spends months configuring software before delivering any value.
Ask how they handle data ingestion: do they build your service inventory from scratch, or do they rely on whatever records you already have? If your existing data is messy, and it usually is, a partner that accepts it at face value will inherit those same inaccuracies.
The BAZ Group begins invoice processing within 30 days of engagement start, even for complex multi-location environments. That speed matters because every month of delayed onboarding is another month of undetected billing errors and missed optimization.
Short-term savings from an initial audit are easy to quantify. The harder question is whether your TEM partner delivers value year after year, or whether the savings plateau after the first engagement.
Look at whether the partner offers ongoing invoice monitoring that catches new errors as they appear, not just a one-time audit. According to a 2026 report by Socium IT, 80% of telecom invoices contain billing errors averaging 5–12% of the total invoice amount. These errors recur monthly, so a single audit without ongoing management leaves significant money on the table.
The BAZ Group builds long-term strategy into every engagement. Its ongoing management relationship helps maintain data quality and capture new optimization opportunities as your business changes.
What separates The BAZ Group from software platforms and payment processors is the depth of human expertise applied to your environment. TEM software is a tool, and its value depends on the quality of data and processes behind it. The BAZ Group brings the specialized team that makes that tool work in practice.
The BAZ Group saves you money by auditing invoices at the line-item level, building verified inventories across locations, and negotiating contracts with current market knowledge. Its independence from carriers means your interests drive every recommendation.
For multi-location enterprises managing voice, data, mobile, and cloud services across dozens or hundreds of sites, The BAZ Group delivers the combination of telecom audit expertise and ongoing management that keeps savings compounding year over year. Schedule a complimentary strategy session to see what your environment could recover.
Telecom expense management is the process of auditing, tracking, and optimizing everything you spend on voice, data, mobile, and cloud services. For multi-location businesses, it matters because telecom waste compounds across every site. The BAZ Group helps you see and control that spend from a single vantage point.
If your reporting is unreliable, your costs are not declining year over year, or you cannot get a verified inventory of active services by location, your current provider may not be delivering full value. The BAZ Group offers a complimentary strategy session that can identify gaps in your current program.
It depends on your internal bandwidth. Software requires your team to maintain data quality and act on insights. A managed services partner like The BAZ Group handles that work for you, functioning as an extension of your staff. Many multi-location teams get more value from managed services because the complexity is too high for part-time attention.
Ask whether the firm has commercial relationships with any carriers, receives referral fees, or resells carrier services. The BAZ Group maintains independence from carriers and vendors. That structural independence helps ensure recommendations serve your financial interests rather than a carrier revenue target.
A capable partner should begin processing invoices in 30 days and surface initial savings opportunities in 60–90 days. The BAZ Group onboards clients quickly because its dedicated team builds your data foundation in parallel with active invoice monitoring, rather than waiting for a lengthy software implementation.
