Salesforce is a more complete CRM with service-specific capabilities, while ServiceNow is dedicated ITSM software that can dabble in customer relationship management. Salesforce is versatile and can be used for managing some IT workflows, but it's not as robust as an ITSM product. ServiceNow is the industry standard for managing back-end IT workflows and is more effective in this area. Both platforms have powerful automation and integration capabilities, allowing users to build custom apps. However, ServiceNow is better suited for issue resolution and has more advanced AI features specifically designed for IT use cases. Ultimately, Salesforce is a better choice for managing customer-facing tasks, while ServiceNow is better suited for back-end IT operations and management.
