Custom NetSuite Suitelet Portal for Customer Self-Service

A distribution company with hundreds of wholesale customers needed to provide self-service access to their NetSuite data without giving users direct NetSuite licenses. Their challenges included:

• Licensing Costs: NetSuite user licenses were too expensive to provide to all customers
• Support Burden: Customers constantly called to check order status, get invoices, and verify account balances
• Branding Requirements: Portal needed to match company branding, not generic NetSuite interface
• Security: Customers should only see their own data, with proper authentication and authorization
• Mobile Access: Many customers needed to access portal from phones and tablets
• Real-Time Data: Portal must show current NetSuite data, not stale snapshots

Suitelet Architecture

We built a comprehensive portal using NetSuite Suitelets with custom authentication:

1. Authentication and Security

• Custom login system tied to NetSuite customer records via email
• Password hashing and storage in custom fields (never plain text)
• Session management with timeout and secure cookie handling
• Row-level security ensuring customers only access their own data
• Failed login attempt tracking and account lockout protection

2. Portal Features
