DataDrillers experience auditing outsourced call center invoicing has found that invoices frequently contain significant errors, and errors most often favor the service providers.

If you use outsourced call center services provider, chances are that you receive a monthly invoice that summarizes hundreds of thousands call records into a few line items. These line items provide little visibility of the charges behind them, and you have no real way to determine accuracy of invoiced charges.

The internals of call center billing is complex. It's based on calculations of call center specific metrics such as work time, talk time, handle time, and agent productivity. Each of these measures can be assembled from multiple switch specific and agent detailed work states. Different rates can apply to different campaign and phone number combinations, agents can perform work on multiple calls at a time, and possibly work for more than one customer at a time.

With this type of environment, the opportunity for billing errors is large. Small errors in billing formulas can have a major impact on amounts charged. We have found that many providers have not automated their backend billing processes and rely on manual processes that involve cut-and-paste into spreadsheets for invoicing on multi-million dollar accounts.

Any discrepancies are noted and worked out as needed with the vendors. If significant errors are identified, we can easily bring more historical data into the system to determine their extent.
