From my understanding of the ERP/CLM space - the reason SAP or coupa etc are expensive is because of the customization and implementation costs associated with deployments.
Even 50-100 person companies have highly customised procurement processes with inter location approvals, transfers etc. How does the system handle all of that?
Do you integrate with other modules like finance & accounting, budgeting, inventory?
There is really a need for a self service SAAS in this space..but this is a very difficult segment to compete in with the majors due to implementation complexities. Wishing you the best!
