Over the years our firm has worked with several Office Supply companies, and I must say that DOS has been the best one to deal with to date. Their customer service is the best I have seen to date. They are more than competitive with …

I've been working with DOS for 12 years and what began as leasing a copier turning into a full service provider for all my office supplies. Their attention to detail has led me to saving time and money. A refreshing feeling to work with an honest and fair sales team.

I needed some high quality prints to showcase my growing progress and they helped me find the best looking options! Better service than any major chain I've been to

DOS and Andrew were a pleasure to work with. Very attentive service from start to finish including after sales service. Would highly recommend DOS and Andrew.

I have been dealing with the team from DOS for over 20 years and it has been an extreme pleasure. The service on our fleet has been excellent as well as the pricing and attention provided to us. The company is very trustworthy, responsive to our needs and can always be counted on in any type of emergency. I would highly recommend them.

We recently leased a Xerox AltaLink colour MFP and was shocked that the quote I received from DOS was half of what I was quoted by Xerox. I was worried that it was too good to be true but went ahead with DOS. The service from DOS with respect to their flexibility with delivery and installation has been excellent. We are now also purchasing paper and toner for our other network printers from DOS since their prices are very competetive and next day delivery is important for us. Highly recommended!

Great company to deal with both for sales and service. I was asked to lease a multi functional copier for my office and didn't know where to begin. DOS helped me choose the right machine which made me a hero in my office. My rep was very responsive and knew his stuff and the support staff is just as impressive. I also switched over to DOS for office supplies and am equall as happy. Highly recommend DOS to anyone looking for a reliable machine that appreciates good service.
