Step 6: Install Bank Bundle
In NetSuite: Go to Customization → SuiteBundler → Search & Install Bundles

NOTE: If the Install button is not visible for the bundle, you may not have been granted access to the bundle. If this is the case, please contact Support.
To search for the bundle, type “Vantage Connect” in the Keywords box and select Search. Ensure the bundle ID is 409974 before selecting. Select Install to review the bundle, then select Install again to confirm. Select Ok when the pop up box appears and wait for the bundle to install (this may take a few moments). Once the bundle has installed, the Vantage Connect plugin tab will appear on your NetSuite menu.
Then, head back to the wizard and select Next Step.

Note: If you will be using Payables, you will also need to install and configure the Entity Bank Details bundle ID 323878.
