Clients call to ask where their matter is.Usually because nobody has told them.

“Any update on my matter?”

Status calls interrupt fee earners all day, and most end with nothing new to report.

Intake in pieces

Other parties’ names, ID copies and background documents trickle in by phone and email before you can clear conflicts.

Confidential documents in inboxes

Drafts, advice and evidence sent as attachments that anyone can forward.

The life of a matter

Give each client one secure place for everything on their matter, and give your team one place to see what’s outstanding.

A web form on your site or a portal form collects client details, other parties and a summary of the matter before the first call.

For legal practices

Built around confidential client work

Secure document exchange

Choose which files each client sees, switch downloads off and let them preview documents in the browser.

Clients raise a new instruction or a question as a service request, which you assign and track to completion.

Corporate clients, many contacts

Add directors, in-house counsel and finance contacts to one client, with a primary contact for notices.

Data rooms for transactions

Run NDA-gated rooms for due diligence and M&A, with user groups, watermarks and an activity feed.

What to expect, explained

Publish guides on your process, costs and timelines so clients have answers before they call.

No passwords to forget

Clients sign in with a one-time code by SMS or email, and your team protects their accounts with two-factor authentication.

Activity

The activity feed shows when a client opens, previews or downloads each file, and you can be notified the moment it happens. No more wondering whether the letter of advice was ever read.

  • Hide a file from the client until it’s ready
  • Switch downloads off for drafts
  • Notify the client when you upload something new

FAQ

Questions from law firms

Can Portalstack run our conflict checks?
No. Portalstack collects the information you need for a conflict check, such as other parties’ names, through your intake form. You run the check in your own system and can comment on or approve individual answers in the submission.
Can clients sign a fee agreement electronically?
Yes. Upload the PDF, place signature, name and date fields, and send it. Each signed document comes with an audit certificate listing when it was sent, viewed and signed, with IP addresses. Check any formal signing requirements that apply to your jurisdiction and matter type.
How do we keep confidential documents out of email?
Share them in the client’s folder instead. Clients sign in with a one-time code, files are stored privately on Amazon Web Services and served through short-lived links, and the activity feed records every preview and download.
Can we share documents with the other side in a transaction?
Yes, with a data room on the Premium plan. Visitors accept your NDA before they see anything, user groups control folder access, and you can watermark files and switch downloads off.
Can clients see the progress of their matter?
Yes. Add a milestone board to the client’s portal with the stages of the matter, due dates and notes. The client can be notified when a milestone moves.
