What Diligent Delivery System's customers have to say about the service they receive.

Customer Testimonials


I just got a personal visit from the President of my company.  He was so pleased and impressed with Diligent that he would like to use you again –without all the extra work of course!  You really did it!

And I am now in a position where mere words cannot tell you what this means to me –thank you is simply not enough –but it is all that I have. I have such sincere gratitude for what you just accomplished that it is impossible to express.  Kindest regards.

Logistics Coordinator

I just wanted to say Thank you for your services. I recently had another company come in and ask to give me quotes because they guaranteed lower pricing. I sent them my last 5 with you and they didn’t even come close. I would also like to say how nice it is that you have prompt and polite drivers.
Thank you.

Director of Operations

"Our company selected Diligent Delivery Systems to decrease our operational expenses and minimize the number of operational headaches on a daily/weekly basis. Diligent has been able to provide our company with an excellent staff, competitive price, and most importantly a promise to provide our customers the same service that has enabled us to become one of the largest Motorcraft Distributors in the country. The move to Diligent has decreased our operational expenses and allowed us to allocate our existing resources in other areas of the business. Our Operations productivity has increased simply on the time and reliability Diligent has allowed us to gain. By using Diligent as your delivery service, operations issues will decrease; allowing more time to be spent on others areas of your business. This has not only been big savings, but also a great business decision for our company. Diligent is, in a sense, a part of our organization. 'One TEAM working towards a common goal'."
