What Our Customers 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 put their opinions in writing. You'll notice some recurring themes.

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

David Webber - ABC Burglar Alarm Systems

"As a company owner, I have been involved in the Alarm industry for over 40 years, many years ago our billing and service system crashed, and we lost most of our customer data. We were referred to Cornerstone Billing Solutions who swiftly restored our operations, re-entering our data and getting our billing and service back on track.

I will say this is the best Company by far regarding the billing solutions, service, and installation tracking required for any Alarm Company with installation service scheduling and monitoring RMR needs. They were able to get our data entered and our billing and service restarted successfully. 

I highly recommend Cornerstone and have only positive comments about the Company and will continue to recommend them to any alarm company. They are the best in the industry by far!"

“I have been in this business for almost 20 years and we have continued to grow as a small business. We decided to switch to Cornerstone after the program we were using became outdated.  

I was very nervous going into it because I don’t like change. It was honestly one of the best business decisions I ever made. The program itself is slick in every way. Recurring charges, credit card processing, and report features are a few of the things I love about the program.

Most importantly, their customer service and tech support are outstanding. The training never stops. They will hold your hand until you understand everything.  I highly recommend Cornerstone.”

“I like that there is flexibility in the software's features to run our business seamlessly. The mobile app has made my job much easier because the techs can complete jobs and invoice in the field, reducing office work! Billing Plus is great too, it makes it easier to stay on top of slow payers with a text. And, their customer service team is beyond anything we've ever worked with!

"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!

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

“In a nutshell, customer service sets them apart from the rest. If you have a question, they respond right away. We don't have to wait to fix the problem. They are always there when we need them. Plus, the software is easy to use! That alone is worth its weight in gold.”
