before proceed further

my company using now

Basically, small companies are using small volume of accounting software version do cater their business needs whereas Multinational companies/conglomerate companies/Manufacturing usually deploy ERP/SAP to cater their business needs
Therefore, I can said all accounting software are good. just depends on the company needs and requirements to run the business transactions

Autocount is good for SME

precisely
but very useful for SME firm

for less 100 users working fine.
Sage ERP seems like under utilized for 108 employees

Max employees depends on the Server hardware size NOT the system
Now ERP can perform near to SAP

cloud is ease of maintenance but depends what kind of apps put into cloud.
For Finance perspective, I think most of the companies still prefer on premise instead of cloud on privacy and security concern

any accounting software come with feature eProcurement system?

one of the portion.
more detail is:
users can submit PR on system with workflow approval process, followed by PO and invoicing as well
