Get in touch


Infor and Crescendo Systems have partnered to provide
an innovative solution to the scheduling puzzle in libraries!

“For years, our customers have been asking me if we have a scheduling solution. Guy introduced me to his solution, CredoPlanning. I was immediately seduced and we then started working on this partnership, based as much on the technical complementarities between our solutions as on the trust and credibility of Guy and his team”.
