Calendly
Calendly is the best scheduling software for small teams (we use Calendly) and enterprise companies considering their stringent employee vetting process and security certifications covering SAML SSO & SCIM provisioning, GDPR compliance, SOC 2 Type II compliance, and much more! In addition, Calendly covers most native integrations such as Google Workspace, video services, and chat tools. If you can't find your application that integrates with Calendly there is always Zapier!
We work with two other scheduling products: OnceHub & Acuity Scheduling - see here for a detailed product comparison. Although, if you have a pre-existing scheduling product you want to use, we are more than happy to integrate it with your software solution.
