Fields
While creating a purchase request in Zoho Expense, you may be prompted to enter data in several fields. These fields might not be required or sufficient for your organization. In order to make your expense reporting experience more efficient, Zoho Expense provides you with the ability to customise existing fields or add more fields based on your organization’s needs.
You can add more fields by creating custom fields to receive additional information and choose the input fields your users would view.
Approvals
You can set up either hierarchical approval or custom approval based on the approval process for the purchase requests in your organization.
Links and Buttons
In Zoho Expense, there are default buttons that are used to execute pre-defined functions. If you want to create a new button apart from the default buttons provided in Zoho Expense, you can create a new custom button and define a set of custom actions that can be executed when you click the custom button.
Custom links are external links that you can configure in Zoho Expense, which when clicked, will take you to external websites or resources in a new tab. You can also add placeholders in these links to redirect users to a specific record or page.
Page Layouts
Customize the purchase request form by creating page layouts to determine the fields shown when users create new purchase requests.
Validation Rules
Validation Rules in Zoho Expense help you create new rules that set restrictions for the data being recorded.
If the value entered in the field violates the condition you’ve set, an alert message is displayed, and the record is not created. The user will also be able to set multiple validation criteria for a single validation rule.
