Offer your clients the option to self-serve.

Client portals do not replace the human touch; rather, they simply provide your clients with a self-service option to access and provide information and documents, at a time and place that’s convenient for them. This saves time, enabling both you and your clients to focus on more productive discussions during in-person meetings.


Your clients deserve a unified portal experience.

It might start with an innocent link to a Dropbox folder, then it’s another link for e-signing, and another for online forms…soon enough, your clients and partners are on the receiving end of a messy experience. Make it easy for your clients and partners to do business with you using our simple client portal software solution.

It's time to ditch email threads for secure client portals.

While email still has utility as a general comms tool, its usefulness for managing client workflows, such as onboarding or collecting client data and documents, has long expired.

Version Control Nightmare

Exchanging multiple versions of documents buried in emails can result in confusion, leading to mistakes and delays.

Massive Time Suck

Trawling through emails results in lost productivity and wasted time trying to locate specific information or attachments.

Lack of Encryption

Emails are not encrypted by default, which means they can be intercepted and read by unauthorized individuals.

Loss of Control

You don’t have control over how it is forwarded, saved, or shared, which can result in unintentional exposure of data.

Attachment Vulnerabilities

Email attachments have the potential to contain harmful malware or viruses that could infect the recipients’ systems.

Risk of Fines & Penalties

With the rise in privacy and data protection fines and legal actions, handling client files and data securely is more important than ever.

Top 3 reasons why your business should adopt client portals

The rate of software innovation is continually growing, introducing a multitude of new software options for professional services firms. The challenge for many of these firms is determining how to allocate the technology investment budget to maximize return on investment.

A common mistake is to adopt a “bottoms-up” approach to technology, starting by focusing on internal processes. This may seem logical, but there is a risk. As the technology stack is being developed, the client experience can often become secondary, or even be completely overlooked.

A more effective approach is to consider technology enablement from a client-centric perspective. Begin by asking questions such as ‘how can technology improve our clients’ interactions with us?’ or ‘what is the best software solution to simplify our clients’ experience?’. Use these considerations as the foundational tech layer, then concentrate on enhancing internal operational efficiency.

Introducing client portals

Establishing a client portal is a great way to leverage technology to enhance both client experience and security. It acts as a digital intermediary between your business and your clients, providing a secure method for handling routine tasks such as collecting client data, sharing files, signing contracts, and tracking service requests.

Here are the top 3 reasons why your business should adopt client portals.

#1 - Your clients have a central place to access important documents

Imagine it’s nearly midnight, and a client is urgently sifting through their email inbox, looking for a document or work item you delivered over a year ago. A client portal solves this issue by providing a central location for all documents.

#2 - It’s more secure than email

client portals are more secure than email

Email has become the primary communication channel for most businesses due to its simplicity and reliability. However, does it serve as a trusted medium for handling sensitive information?

Think about the journey of a typical email. When you press ‘send’, the email and its attachments don’t simply transfer from your inbox to the recipient’s. Instead, they traverse the internet, unprotected, passing through multiple servers before arriving at their destination. At each server transition, your email is vulnerable to server administrators who, theoretically, could modify or even erase your email content.

We’re not suggesting that you completely abandon emails. However, client portals offer a more secure method for exchanging sensitive client information over the internet.

#3 - Data collection is easier and less prone to error

Using paper or PDF forms to gather and manage client data is not only inefficient but also prone to translation errors. Plus, completing static forms can be monotonous. Modern client portals, such as Portalstack, incorporates an intelligent digital form builder. These digital forms enable you to design interactive forms dynamically, simplifying your data collection process and making it less tedious for your clients.

The bottom line

Portalstack’s client portal software solution strengthens the bond between your clients and your business by offering a unified and user-friendly platform for collaboration. This secure area reassures both you and your clients that sensitive information is well-protected against potential cyber threats.
