This feature lets you select a custom NetSuite field to display as the identifier instead of the default transaction number that appears on your Payment Links.. For example, instead of showing the standard NetSuite Sales Order number, you can choose to display a Salesforce Quote Number to provide a more familiar reference for your customers.
Go to PayPack → Setup → Configuration → Payment Link, and select a Custom Transaction Details Field.
When using Invoice Group payment links, select a Custom Invoice Group Details Field.
Ensure the NetSuite transaction has a field value populated. Otherwise, the PayPack payment link will default to the original transaction number.
