Onboard new clients up to 80% faster with Portalstack client onboarding software

Client onboarding is one of the most important processes in the client engagement journey – it’s an opportunity to make a good first impression post-sale (nobody likes to experience buyer’s remorse). But collecting information to onboard new clients can often be a real pain (for both you and your clients).

It's time-consuming

Collecting information to onboard new clients is time-consuming. This inevitably delays the service delivery phase of work (the value-added part your clients actually pay for).

Client experience suffers

The traditional PDF forms and back-and-forth email threads no longer cut the mustard. Your clients deserve a modern client onboarding experience.

Version control is messy

Client onboarding via endless streams of emails is a version control nightmare. You run the risk of actioning services based on information buried within superseded emails.

Use rich content for better engagement

Don’t overload your clients with text-heavy instructions buried in static docs. A better approach is to incorporate a mix of dynamic text with rich content such as images and videos.


Always be informed of progress

Get notified immediately when an onboarding form is ready for your review. Get daily notifications of the completion rate for all in-progress forms.

Frequently asked questions

No. Unlike other client onboarding software, Portalstack does not impose a limit on monthly ‘active requests’ (i.e. the number of monthly onboarding forms you can send to clients requesting information).

Essentially anything that your clients can input or upload can be collected – for example, client data, business information, content, documents, images, files, etc.

Is there a charge for client access?

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

How secure is the data?

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.
