Why Connect Cal.com to Deputy?

Student enrolment data in Cal.com and billing records in Deputy are managed separately, causing discrepancies

Cal.com limitations compound the integration challenge: self-hosted version requires technical setup and maintenance, including database management and deployment configuration

Manually copying data between Cal.com and Deputy wastes hours every week that could be spent on revenue-generating work

New team members take longer to onboard because they must learn manual workarounds to keep Cal.com and Deputy aligned

Reporting across Cal.com and Deputy requires painful manual exports and spreadsheet merges
