Calendar and scheduling integration for Google Calendar, Outlook and Calendly, plus reminders, time zones and buffers. Custom integration development from $500 to $1,200 in 3 to 8 days.
The problem
Clinics, consultants, salons and coaching centres in Dubai and Bangalore still take bookings by phone and WhatsApp, then copy them into a calendar by hand. Slots get double-booked, time zones confuse overseas clients, and no-shows cost 20 to 30 percent of revenue because nobody sent a reminder. Generic booking widgets look off-brand and do not talk to your CRM or payment system.
What we build
We integrate Google Calendar, Microsoft Outlook or Calendly directly into your website or app, with live availability, buffers, time-zone handling, deposits via Stripe or Razorpay and automatic WhatsApp, SMS and email reminders. Using Claude Code and Cursor we scaffold the OAuth flow, availability engine and reminder jobs in a day, generate the edge-case tests with GPT, then verify the booking flow end to end on your real calendar. You keep the full source code at a fixed price between $500 and $1,200, never more than $2,500.

FAQ
Calendar & Scheduling Integration (Calendly, Google Calendar): common questions
How much does calendar integration cost?
From $500 for a single calendar with reminders to $1,200 for multi-staff availability, payments and CRM sync, delivered in 3 to 8 days. The price is fixed up-front and never exceeds $2,500.
Do you get access to my calendar?
No. The connection is authorised through Google or Microsoft OAuth in your own account, and tokens are stored encrypted in your database. We never see your events.
Can each staff member have their own availability?
Yes. Each team member connects their own calendar, sets working hours and services, and customers pick a person or the next available slot.
