Im a certified salsforce administrator with over 2 years expertise with implementations for various countries and industries.
Salesforce is the #1 CRM in the world, not that I say it, and it has been recently rewarded by Forbes as the World´s most innovative company of the entire world.
I have read the list of requirements and I´m 100% confident that according to your needs, it´s the best tool you may probably find out there. You can have your outlook integration setup easily and mobile version is one of the most powerful.
I think you still have a huge opportunity to make the right choice.
Please let me know if there´s anything I might do to take the decision and migrate to salesforce.
Thanks in advance.
Sebastian
