Shopify Setup with Booking System Integration

I need a developer who knows Shopify inside-out to add an appointment-scheduling system to my store. The key requirement is reliable Google Calendar sync so every new booking instantly shows up in my business calendar and any changes propagate both ways.

Here’s how I picture the flow: a customer picks a time slot on the storefront, pays or confirms (the payment workflow is already handled by my current checkout), and the slot is immediately written to Google Calendar. Staff will also need to see updates if a customer reschedules or cancels.

If you already have a preferred Shopify app or custom approach that handles Google Calendar sync smoothly, I’m open to it as long as it stays lightweight and doesn’t slow page speed. Suggested apps include Cowlendar, Apntly, Easy Appointment Booking, BookX, or Meety, but I’m flexible as long as the solution meets my requirements. Experience working with Shopify APIs, app configuration, Liquid tweaks, and basic theme styling will help us move fast.

Deliverables:
• Install and configure the appointment-scheduling solution on my live Shopify theme
• Activate two-way Google Calendar sync and prove it with test bookings
• Provide a short guide or screen recording so I can add, disable, or edit time slots myself in the future

The store is live, so I’d like minimal downtime. If you can start soon and have done similar integrations before, let’s talk.
