Has anyone in the group used an e-Sourcing solution? What are your thoughts?

I have been a buyer for raw material and responsible for new suppliers development for almost 8 years and never had the opportunity to work with an eSourcing Solution. Now I am a Product Owner for a Strategic Sourcing Solution in a Tech Company and just can't see myself going back to Procurement without it... Please let me know your thoughts if you experienced working with it. Thank you so much! https://www.linkedin.com/pulse/procurement-teams-super-heroes-isabela-may?trk=prof-post
