When a customer ran into other solutions, i.e., enabling Invoice as payment to the webstore using One Page Checkout (27523), the Terms field needs to be set.
Sometimes, user cannot locate where the Terms field is from the customer record that should be under the Financial subtab.
To display the Terms field, the AR feature needs to be enabled:
1. Using an Administrator role, log on to NetSuite
2. Navigate to Setup> Company> Enable Features
3. Click the Accounting tab
4. Check A/R
5. Save the changes
