Clients see their own matters. Nothing else. Documents, status and invoices in one place.

Each client sees only their own matters, documents and invoices, exchanges files securely and sees what happens next. Every access is logged, and we keep it patched.

What we usually hear

What firms usually tell us before a portal, and what we change first

“Clients email every week for an update.”

Each matter shows where it stands, what is needed and the next date.

“Confidential documents travel by email.”

Uploads and downloads in the portal, stored where no outsider can open them.

“Nobody knows who opened what.”

Every view, upload and download logged with who and when.

“Invoices and requests get lost in inboxes.”

Invoices, document requests and sign-offs kept with the matter.

“Former staff may still have access.”

Roles per person, reviewed when staff join or leave, and removed in one place.

What you get

Six things the portal does, built and run by the same engineers

01

Each client sees only their own

Access per client and per matter, checked on the server for every page and file, so nobody sees a matter that is not theirs.

02

Documents exchanged securely

Clients upload and download in the portal instead of by email, and files are stored where no outsider can open them.

03

Status without the status email

Each matter shows where it stands, what is needed from the client and the next date, updated by your team.

04

Every access logged

Who opened, uploaded or downloaded what, and when, kept in a log your firm can show when asked.

05

Invoices and requests in one place

Invoices, document requests and sign-offs live with the matter, not in separate email threads.

06

Kept patched and watched

Updates tested on a copy first, monitoring, backups we have restored, and access reviewed when staff change.

Who it is for

For firms that handle confidential work for many clients

A good fit

Status and documents take hours every week.

Every status email and every attachment costs time and leaves another copy of confidential data in an inbox.

  • You handle confidential matters for many clients at once.
  • Status emails and document exchange take real hours every week.
  • You want each client to see only their own work, with every access logged.
Law firms · Tax advisers · Accountants · In-house legal

Not a fit yet

A few clients you see in person?

Email and a well-kept folder are enough, and we will say so.

Come back when the client list grows.

Want to replace your practice software?

We do not build practice management software. The portal is what your clients see.

Keep it. The portal works alongside it.

How a portal gets built

Who sees what first, then the portal

  1. Step 01

    Agree who sees what

    Clients, matters, roles and what each one may see and do, written down with your partners before anything is built.

  2. Step 02

    Build the portal

    Matters, documents, status, invoices and logs on a test copy your team and a few trusted clients can try.

  3. Step 03

    Connect your systems

    Matters and invoices pulled from your practice management or accounting software where it allows, so nobody retypes them.

  4. Step 04

    Run it every month

    Patches, monitoring, backups and access reviews, with the same engineers every month.

FAQ

Questions firms ask before a client portal

Every page and every file checks on the server who is asking and what they may see. We test it with a second client account before launch and after every change.
In the EU, on our server in Frankfurt, by default. If your professional rules need somewhere else, we agree it with you before we build. We sign our Data Processing Agreement as your processor and an NDA before any access. For firms in Türkiye we sign the KVKK standard contract on request; the agreement is in Turkish too. You contract with Reaktör Teknoloji Tic. Ltd. Şti.
No. The portal is what clients see; your practice management or accounting software stays where your team works. We connect the two where your software allows it.
They can review and confirm in the portal, and we can connect the e-signature service you already use.
We do, on a monthly plan: patches, monitoring, backups we have restored, and access reviewed when staff join or leave.
