Under Web > Buttons, you can create custom "Book Now" buttons for your website - or any other place that accepts HTML code (like blogs, email, etc.). You can change the color, size, call-to-action - even pre-select the service or provider.
By default, the button links to your landing page on Full Slate so clients can select from the full list of services that you offer. If you want to bypass that list and jump straight to available times for a specific service or staff member, just change where it links to. For example, if you already have a menu or price list on your website, you could add buttons that link to openings for each service. Or say you have a new staff member who's offering a discount to help build clientele - you could put a button next to their bio that links to openings with that specific provider.
Once the button looks the way you want it, copy the code at the bottom of the page and paste it into your webpage wherever you want the button to appear. If someone manages your website for you, you can paste the code into an email and send it to them instead.
