We are a large university and are seeking vendors who currently have other higher education clients with their solution. Can you please provide me the vendors currently in this market niche?
We don't maintain a list of automation vendors specifically tailored to higher education. I was able to find this whitepaper discussing P2P in higher education: https://www.corcentric.com/resources/whitepaper-purchase-pay-higher-education/, which you may find useful.
A few vendors that seem to have a presence in the higher education space are Corcentric (https://www.corcentric.com/), Lexmark (http://www.lexmark.com/en_us/solutions/higher-education.html), Concur (https://www.concur.com/newsroom/t/ap-automation), and Chrome River (https://www.chromeriver.com/customers/universities-colleges-need-expense-management). That was just through a quick Google search; you will probably find others. Also, please understand that we cannot recommend any of these, as we have not worked with them and cannot endorse them.
Finally, I would direct you to this PowerPoint presentation on our IOFM AP&P2P Network that addresses automation in higher education: http://iofm.com/conference-spring/wp-content/uploads/2016/01/Unique-Nature-of-AP-in-Higher-Education1.pdf. That may provide you with some helpful information as you explore your options.
