Benefits of a modern client portal for agencies.

Clients pay you for your expertise in designing digital experiences, not for non-value-added admin work such as chasing documents and content or trawling through inboxes to find information.

Win and retain more business

Differentiate your business by delivering your clients an integrated digital experience.

A faster way to collect information

Make collecting data, content, documents and signatures from clients stress-free.

Improve productivity with digital workflows

Replace manual paperwork to free up your time, so you can focus on higher-value client work.


Still using email to exchange client information?

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.

Any of this strike a chord?

If I got a dollar every time a client asks me to urgently resend project files (mockups, web copies etc) when I’m offline or in a meeting, so can’t respond immediately…well, let’s just say I could comfortably retire in Bali surfing all day!

I’m embarrassed to admit this, but I’ve been in hot waters with clients for working off outdated files (totally missed that last email with an updated version! my bad). The rework was brutal, but more importantly, it made me look like an amateur. 

Truth be told, I’m not helping myself (or my clients) by allowing email to be the default communication channel for sharing files and collaborating with my clients. As an agency, we need a smarter solution.

Keep client interactions organized in one secure client portal.

Portalstack offers all the tools you need to build meaningful business relationships with your clients – client management just got easier.

Create, send and track digital documents.

Block-styled document editor to create web documents. Use rich content such as images and videos to make your documents more engaging. Get notified when your clients view or approve your documents.


Securely exchange sensitive documents.

Avoid the inherent risks of sharing files and attachments via email. Get notified when your clients open, preview, or download a file. Save time by uploading files to a common folder across all clients.


Get your documents and agreements signed faster.

Simply upload your document, drag and drop your input blocks, assign them to a client, and hit send – it’s that easy. Transactional data, such as the date, time, and IP addresses of all signatories, is recorded. Keep track of documents pending signatures and schedule automated reminders if needed.


Keep your clients updated on your service milestones.

Minimize client follow-ups by sharing and updating the statuses of your key service delivery milestones. Centralize communication with persistent chat messaging. Add tasks to provide your clients with a more detailed work breakdown.


Centralize new client service requests.

Allow your clients to raise and track new service requests. This will make it easier to plan, prioritize, and deliver your services. You can triage and assign new service requests to team members, as required.
