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

As software options for service-based businesses continue to expand, deciding where to invest your technology budget can be challenging. Many businesses make the mistake of prioritizing internal processes over the client experience.

A better approach is to focus on the client first. Ask yourself, “How can technology enhance the way I interact with my clients?”. By prioritizing the clients’ needs, you can build a strong foundation for your tech stack while also improving internal efficiency. This approach ensures that your investment in a client portal software is impactful.

Client portals - your new digital front desk

Think of client portal software as like having a friendly digital assistant for your business interactions. 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. Client portals solve this issue by providing a central location for all documents, accessible 24/7.

#2 - It’s more secure than email

client portals are more secure than email

Yes, email has become the primary comms channel for most businesses due to its simplicity and reliability. But 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 could modify or even erase your email content. Client portals offer a more secure method for exchanging 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, let’s be real – who enjoys completing static PDF or word forms? 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 strengthens the bond between your clients and your business by offering a unified and user-friendly platform for collaboration. Having a  secure space reassures your clients that sensitive information is well-protected.
