If you have prices that are customer-specific, i.e. Access prices, then the Customer Tag rule is a useful way of setting visibility.
With Customer Tag, you can set a rule that a price will only show for customers that have a certain Tag attached to their profile.
For Access customers, you can:
Add a Tag to certain customer profiles, e.g. access
Create an Access Variant on your Price Table
Add a Visibility Rule and select the Customer Tag is option
Select the Access tag you've created
This price will then only appear when these customers log into the Website booking flow
NOTE - You will need to have customer login enabled on your Customer-Facing Booking Flow for this to work.
