Secure Client Portals

A place your clients trust with their work.

Per-client workspaces for the files, documents, and updates you share — branded as your firm, versioned, e-signable, and logged. One link instead of an email thread, with a permission model that never leaks data across customers.

Confidential client work, shared somewhere safe.

01The idea

Your client's most sensitive documents are sitting in an email thread.

You do confidential, high-trust work — and then you share it the least trustworthy way there is: as an attachment that lives forever in inboxes you don't control, with no current version and no record of who opened it. A client portal replaces that with one branded place per client, where the latest documents live, access is scoped and logged, and signing happens in the same room. It doesn't just look more professional. It quietly removes a category of risk you've been carrying.

02The signs

You already feel the risk.

Each familiar worry has the same answer — a place built for trust.

  • 01

    You email files and worry where they end up

    One controlled workspace — not an attachment loose in the world.

  • 02

    Clients keep asking “can I see the latest X?”

    Versioned documents they can always reach, current by default.

  • 03

    Compliance requires access logs

    A precise record of who opened what, and when.

  • 04

    Contracts bounce around as scanned PDFs

    E-signature in the same place the work already lives.

  • 05

    Different clients, different confidential data

    Strict per-client isolation, enforced on the server.

03What we build

One link that holds the whole relationship.

Everything you currently scatter across email, drives, and signing tools — gathered into one place, per client.

04Branded per-client workspaces

It feels like working with you.

A portal is the part of your service a client touches every week, so it should look like your firm — not like an app you bolted on. Each workspace carries your logo, colours, and domain, with a layout shaped to how you actually work with clients. For enterprise clients it can live on your own subdomain with their single sign-on.

  • Your logo, colours, domain, and tone
  • A layout shaped to your service
  • On your own subdomain for enterprise
  • An extension of the relationship, not a tool

Versioned documents
05Versioned document sharing

One current version. Always.

The endless 'final_v3_REALLY_final.pdf' over email ends here. Documents are versioned, so there is always one clearly current file with the full history behind it. Clients see the latest automatically and can review what changed — and you can see whether they have actually opened it. The recurring 'can I see the latest?' email simply stops.

  • One clearly current file, with history
  • Clients always reach the latest
  • See what changed, and who opened it
  • Folders and structure that match your work
06E-signature, built in

Sign where the work already lives.

Contracts, engagement letters, and statements of work get sent, reviewed, and signed in the same place as everything else — no separate signing tool, no chasing scanned PDFs back over email. The signed document is filed, versioned, and logged automatically, which is exactly what your records and your auditor want.

  • Send and sign without leaving the portal
  • Signed copies filed and versioned automatically
  • A clean audit trail on every signature
  • Less chasing, faster turnaround

Access logs and permissions
07Isolation & access logs

Know exactly who saw what.

Two things keep a portal trustworthy: nobody sees another client's data, and you can prove who saw yours. We enforce per-client isolation on the server for every request, and keep an audit log of opens, downloads, signatures, and permission changes. When a client, a regulator, or compliance asks 'who accessed this?', you answer with a record, not a guess.

  • Strict per-client data isolation
  • Audit log of every access and change
  • Exportable evidence for compliance
  • Permissions that are simple to reason about
08Trust, made visible

The portal that makes you look as careful as you are.

Fast, clear, and obviously secure — the kind of experience that tells a client their work is in good hands before you say a word.

09How we work

Built for trust before it is built for features.

01

Map the relationship

We learn how you actually work with clients — what you share, who needs to see it, and where the confidentiality lines are.

02

Design the workspace

We design a branded per-client workspace and the permission model, so isolation and access are right by design, not by patch.

03

Build documents & signing

Versioned document sharing, e-signature, billing visibility, and tickets — the parts of the relationship that live online.

04

Harden & log

We test the cross-client cases deliberately, wire up access logging and SSO, and prepare the evidence compliance will ask for.

05

Migrate & launch

We bring across your existing files, organise them per client, and roll the portal out — to your team first, then your clients.

10Right when

The email thread has outgrown its job.

  • You email files and worry where they end up

    Every attachment is a copy you can't recall, in an inbox you don't control. A portal keeps the file in one place you do.

  • Clients keep asking to see things

    Documents, invoices, status — if a client has to email you to see them, that's a portal waiting to be built.

  • Compliance needs access logs

    When the answer to 'who saw this?' has to be exact, hope and email search don't qualify. A record does.

12Questions

The things firms ask us first.

Email feels easy until you think about where those files end up. Once sent, an attachment lives forever in inboxes you don't control, gets forwarded to people you never met, and leaves you no record of who opened it. There's no single current version, so clients work from last month's draft. A portal replaces all of that with one branded place per client where the latest documents live, access is controlled, and every view is logged — so you stop hoping a sensitive file behaved itself.

Give every client a place they trust.

Tell us how you share work with clients today — the files, the signing, the back-and-forth. We'll design a branded, secure portal that replaces the email thread and gives you a record you can stand behind.
