Has a carrier sales representative ever pitched you on the benefits of a single invoice for all of your telecom services? This may sound convenient, but it often costs you in the long run. . .
The main reason is that a single invoice tends to obscure important details. Payment of the bill is done as a single item, as that is how it is delivered.
The danger is in not looking at the details to see exactly what is being paid for.
Let's say that your company has 10 offices around the country and decides to consolidate a few. In the process someone fails to have the telecom circuits turned off at one (or more) of the closed locations. This actually happens all the time.
As time passes everyone forgets. Because your company receives a single telecom invoice for all locations it keeps paying that bill without realizing that it is being charged for circuits (or other services) that are no longer in use.
Without TEM, it's easy for errors and oversights like this to occur. With TEM, the automated comparison of invoice details against the contract ensures that such errors come to the surface immediately.
