2.⁠ ⁠Treatwell - https://www.treatwell.com/
3.⁠ ⁠Ovatu - https://ovatu.com/

Here are the required functionalities which much be written in Node.js as a script or API:
1.⁠ ⁠Data Retrieval either by browser scraping or the CRM's API:

- Get services offered by the salon (categories, name of service, type of service, etc)
- Get bookings and calendar data (given date range)

- Get customer details (name, email, phone number, birthday, booking/appointment history, etc)
- Get products/retails/inventory information (product name, sku, product details, discounts/promotions, remaining stock, etc)

2.⁠ ⁠Automation:

This is Phase 1 and we target to complete it by June 30th.
