Frequently asked questions

Is there a charge for client access?

No. You can add as many clients as you want. We only charge you for advisers (your internal users) under your subscription.

How will my clients access the portal?

When you sign up to Portalstack, you’ll be assigned a unique login URL. This URL will be used by both your clients and internal users to login. We recommend you create a ‘Client Login’ button on your website that links to this URL. Otherwise, you can share this URL with your team and clients.

We take data security seriously. Our platform is hosted on Amazon Web Services sitting behind their bank-grade infrastructure with 256-bit encryption. We’ve designed Portalstack with a security first architecture. You can find out more by reading our Security Policy.
