Kintsugi (powered by Vertex) now supports a read-only integration with NetSuite. This integration syncs your NetSuite transaction data into Kintsugi, supporting both Legacy Tax and SuiteTax environments.

Get your Account ID.
Go to Setup > Company > Company Information.
On your Company Information page, scroll down until you see your Account ID

Copy the Account ID.
To grant access to the Netsuite, you need to create a user role to get Access Tokens using Token-Based Authentication
Go to Setup > Users/Roles > Manage Roles > New
Give the role a name (e.g. Kintsugi Role).
Under the 'Permissions' tab, select the appropriate permissions for the role. The role needs the necessary permissions to perform the integration tasks.
