To Whom It May Concern:

For years we suspected that we were being overcharged by our credit card processor. However, no one here had the time or knowledge to get at the details behind our monthly processor charges. PE Systems Inc. stepped in and found the information for us. They then negotiated with our processor to get us the lowest rates possible. Additionally, they got the credit card processor to refund some of the overcharges. Not only did PE Systems find that we were being overcharged, they pointed out very simple changes that we could do, that would keep us at the lower rates.

I strongly recommend the services of PE Systems Inc. if you wish to be assured that you are receiving the best credit card processing rates possible for your business.

Sincerely,
...
