You can set up Book4Time to calculate tax before applying a discount or after applying it.
To ensure that tax is applied to the POS before any discount:
- Navigate to Admin > System Settings > POS Settings > Defaults.
The list of settings appears on the right.
- Click Edit.
- Select the Calculate Tax Before Discount checkbox.
Now, Book4Time will calculate tax before discount or based on the original price.
Important: That this is a global setting. Once this is enabled it will apply to all locations.
