You can create custom formulas to calculate new values based on information Practifi. For example, you might create a formula to return "VIP" if a customer has an account balance above a given threshold.
Formulas can be created using custom fields in the Salesforce Platform, or using UI-only fields using the Skuid page composer. Formulas in Salesforce are great for calculating values to be displayed in multiple pages. Skuid UI-only fields have the benefit of updating in real-time as the user edits information, but are limited to use in a single page.
