How does Cal.com work?

Audit & scope
Doctors, therapists, consultants, coaches, sales teams, and service businesses use Mithtech-deployed Cal.com to eliminate phone-based scheduling — clients self-serve, pay at booking where relevant, and get automated WhatsApp + email confirmations + reminders that crash no-show rates. A free 30-minute call maps where Cal.com pays back inside year one and locks the scope — with an honest read on where Cal.com doesn't fit.
Deploy on your infrastructure
MithTech stands Cal.com up on infrastructure you own — your cloud or servers, with Indian data residency. Your Cal.com source code, schemas, and operational keys stay with you.
Customise & integrate
We connect Cal.com to the tools (including Polygin, Polygin, ERPNext) and tailor fields, roles, and booking workflows so Cal.com matches how your team actually works.
Train & roll out
Every team that will use Cal.com gets onboarding and documentation written for your tenant, and MithTech stays on the support thread through the first 30 days of Cal.com go-live.
Operate & evolve
Optional managed operations keep Cal.com monitored, patched, and upgraded as its booking roadmap moves — with Cal.com you pay only for what you use.
