Diesel TMS has all the tools and data just like all these other expensive PAID softwares... FOR FREE. This system is easy to use and fully customizable. Not to mention, Diesel support is always a quick chat away to help, they even built my interface the way that suits my workflow. Can accommodate to both the carrier and brokerage side with seamless transitions. Thanks to James for all his support!

This has been a really nice program to use & a great experience when having to call or email with the people working at Diesel TMS. We have used four different TMS systems over the past five years & Diesel has been the best one out of all of them. There is one main reason for our opinion & that is the willingness of the people at Diesel TMS to make sure the program has what you need. If you call them & explain a feature that the program does not have & they see the value in it for the program & their other users, they will add it to the program. This was really a welcome surprise. Other companies have offered to do this but ask for a ridiculous fee to add the feature. Diesel TMS has added a few features that we asked for & they never charged us anything extra for it. On top of that, any time we have called to ask them to show us a feature or walk us through something they have done it every time & with the utmost patience. Five stars for this company & highly recommended.

Easy to learn with plenty of features. I like how you can manage the asset side and brokerage side within the same software. Good support with people that understand the industry.

I still can't get over how you can offer such a comprehensive software for free. Having everything you need to run a brokerage or trucking company in one place. You really thought of everything. Great job Diesel 🙌
