What Our Security Dealers Say...

It's not our style to brag. But we keep hearing from our dealers, "More companies should know about Cornerstone!" So we asked for a few of them to record their opinions of us... and this is the result. You'll notice some recurring themes.

Give us a call at 224.577.1197 to see if we are the right fit for you.

I count on Cornerstone to be there for me, so I can be there for my customers.

They save our office time, they save us a lot of aggravation, and most importantly they save us money!

Their customer service is phenomenal, they always pickup immediately when we call, it’s always a live person I’m talking to, and they always solve any issue we have in a timely manner.

On a 1 to 10 scale, I give Cornerstone a solid 13!

Cornerstone has helped our business numerous ways: streamlining our billing, our collections, accounting processes. Made life much simpler, requiring less personnel and less aggravation on our end.

Easy to Learn and Use

Pioneer Security Services

Cornerstone has been a pleasure to work with.   I’m so glad we made the switch from Quickbooks.  The software is easy to learn and use, and their staff is outstanding, and so willing to help.   We referred another dealer to Cornerstone, and they were very reluctant to “give up control.”  But after they switched, they thanked us profusely for the recommendation.

What’s not to love about not handling printing, mailing, or posting payments?   We also happily use Cornerstone’s Billing Plus to track down slow payers, and we have the BEST LOOKING aged accounts receivable ever!
