The customer service is excellent! I have been working with them for several years now, but they are always willing to help me out when I need it. They are very organized and efficient in their workflows. They know how to get things done efficiently. I don't have any complaints at this time, however, if there is anything that could be improved I would like to see the ability to use a different font size than 10pt. It's easier to read smaller text and there are times where I am doing quotes or other documents where the text needs to be larger. I've seen many companies offer quote and document creation, but I haven't found one that has the same level of quality as House of Printing. We do all our invoicing, proposals, contracts, etc. through House of Printing. I also love having all my files in one place.
