Client Experience

Client Management and Portals

Clients judge a firm on the parts they can see: how they send you a document, how they sign something, and whether they can tell what is happening without emailing to ask. This pillar covers the design and security decisions behind a portal clients actually log into, and the ones that quietly push them back to email. The Accupe portal is isolated per client, branded to your firm, and reached with a client code and PIN, with a no-login deposit box for the clients who are never going to log in at all.

The fundamentals.

What every firm should have straight on this topic, whether or not it ever uses Accupe.

Isolation before features

One client must never be able to reach another client’s records, enforced in the database rather than in the interface. Ask a vendor how it is enforced, not whether it exists.

A login clients will accept

A password reset flow loses the client who signs in twice a year. A short code and PIN, or a link that needs no login at all, gets you the document.

Somewhere to drop a file

A no-login, upload-only page means a prospect can send you a document before they are a client, and a client can send one without hunting for credentials.

E-signature mechanics

Fields placed per signer, a signing order, reminders, an expiry date, and a decline that captures a reason. The detail is what makes the signature hold up rather than just look modern.

Proving who signed

A signing link on its own proves somebody had the link. A one-time code sent to the signer’s email address, recorded on the completion certificate, is the difference between a signature and an assertion.

Branding that goes all the way

A portal that looks like your firm until the moment an email arrives from somebody else’s domain is a portal that undoes its own work.

Field guide

Why portals fail, and what makes one stick.

Most firms that bought a client portal are not using it. The software works; the adoption did not. Almost every failure traces back to three things: signing in is harder than replying to an email, there is nothing inside worth the trip, and the firm kept accepting attachments anyway.

Adoption is the whole product

A portal that half your clients use is worse than no portal, because now documents arrive through two channels and neither is complete. The honest way to evaluate one is not by feature list but by asking what percentage of client document exchange actually goes through it after six months.

The three reliable killers are friction at the door, an empty room, and a firm that never closed the old door. Each has a straightforward fix, and none of them is a feature.

  • Friction at the door: a client who signs in twice a year will not remember a password, and a password reset that goes to an email they no longer check ends the relationship with the portal permanently
  • An empty room: if the only thing inside is a folder the client already has copies of, there is no reason to return. Put the thing they actually want in there, which is usually the current status of their work and the document they need to sign
  • The old door left open: if a client can still email an attachment and get a reply, they will. Adoption is a decision about how your firm responds, not about how the software is configured

Isolation, and the question to ask a vendor

A multi-tenant portal holds every client’s records in the same database. The question that matters is where the separation is enforced. If the application filters records by client identifier when it builds a page, then a bug, a crafted request or a stale link can return somebody else’s data, because the only thing stopping it was a line of application code.

The stronger design enforces the boundary in the database itself, so a query issued on behalf of one client cannot return another client’s rows even if the application asks for them. In Postgres that is row-level security. The right question to a vendor is therefore not "is client data separated" but "where is the separation enforced, and what happens if the application layer asks for the wrong record".

The related question is what a portal login can actually reach. A client identity should not be able to read staff-only notes, other clients, or firm-level records, and it should not be able to change its own permissions. Ask how that is tested, not whether it is true.

Login models, and the trade-off nobody states plainly

There is no perfect option here. There is a trade-off between security posture and the probability that an infrequent user gets in at all, and firms should choose it deliberately rather than inherit it.

How the common portal sign-in models behave for a client who logs in two or three times a year.
ModelWorks well whenFails when
Email and passwordClients log in often and use a password managerThe client forgets, resets to an unmonitored inbox, and gives up
Emailed link with no passwordYou want zero friction for a one-off actionThe link is forwarded, or spam filtering delays it past its expiry
Short client code plus a PINClients are infrequent and the firm issues and resets credentialsCredentials are shared casually, so PIN reset discipline matters
No login at all, upload onlyCollecting documents from prospects and reluctant clientsNever suitable for letting anyone read or download anything

A pragmatic pattern is to combine them: a credentialed portal for clients who will engage with it, and a no-login, upload-only page for the ones who never will, so a document you need still reaches you rather than sitting in an inbox. Accupe uses a client code and PIN for the portal, with a separate Secure Deposit Box page that accepts uploads against a client code without any sign-in and cannot be used to browse or download anything.

E-signatures: what makes one hold up

Electronic signatures are ordinary in UK business practice. The general position is that an electronic signature is capable of executing a document where the signatory intends to authenticate it, and the practical questions are evidential rather than existential: can you show who signed, what they signed, and when. The UAE likewise recognises electronic signatures under its electronic transactions and trust services legislation, with a higher tier available for authenticated signatures.

There are exceptions worth knowing rather than assuming. Deeds have their own execution formalities including witnessing, and certain instruments in both jurisdictions sit outside the general position or attract additional requirements. If a document class is unusual, check it once rather than per transaction.

Terminology also matters when a counterparty pushes back. A simple or advanced electronic signature is what almost all business agreements use. A qualified electronic signature involves a certificate authority and secure signature creation hardware, and is rarely required in ordinary practice. Accupe issues simple or advanced electronic signatures, and says so plainly rather than implying a qualified one.

  • Identity: how did you establish that the signer was the person you invited. A link on its own only proves somebody had the link. A one-time code sent to the signer’s own email address, recorded on the certificate, is materially stronger
  • Intent: an explicit act of signing and an attestation, not a checkbox buried in a page
  • Integrity: a cryptographic hash of the signed document, so any later alteration is detectable. Accupe records a SHA-256 hash of both the original and the signed file and exposes an integrity record anyone can check
  • Attribution and time: an audit trail of invitation, view, verification, signature and completion, with timestamps, and ideally an independent time stamp rather than only the vendor’s own clock
  • Completeness: per-signer fields so signer two cannot fill signer one’s boxes, a signing order where sequence matters, an expiry, and a decline that captures a reason

Branding that does not stop at the front door

Branding a portal is not vanity. It is the difference between a client trusting a document request and treating it as a phishing attempt. The weak point is almost always the email: a portal that carries your logo perfectly, announced by a message from a domain the client has never seen, undoes its own work at the only moment it mattered.

Decide how far you want to take it before you roll out. Logo and colours are the cheap part. A custom domain and white-labelled notification emails are the parts that need DNS work and, in most products, a higher plan. In Accupe the firm logo appears on the portal on every plan, while portal colours, a custom domain and white-labelled client emails are Elite features.

Offboarding, retention and the awkward questions

Portals accumulate. Every engagement letter, identity document and signed return sits there indefinitely unless somebody decided otherwise, which is a data protection position taken by default rather than by choice.

Answer four questions before you roll out rather than after a client asks: what happens to portal access when an engagement ends, how long documents are retained afterwards, what a client is entitled to take with them, and who at your firm can delete something. Handled at the start these are three lines in your engagement letter and a setting. Handled later they are a conversation with a former client.

In practice

How firms actually get a portal used.

Rollout beats configuration. The firms with high portal adoption did the same seven things, in roughly this order, and none of them involved a longer feature list.

  1. Start with one cohort, not the whole client base

    Pick twenty or thirty clients with an active piece of work in the next month. A rollout to everyone at once produces support load with no signal about what is going wrong.

  2. Seed every portal before you send the invitation

    Nobody logs in to an empty folder. Put last year’s accounts, the current job status and anything awaiting signature in there first, so the first visit is worth making.

  3. Send credentials the way the client already hears from you

    A message from your firm, with the code and a link, at a moment they are expecting to hear from you. Credentials arriving out of context read as phishing and get deleted.

  4. Move one workflow entirely, and be firm about it

    Signatures are usually the best first candidate, because there is a genuine reason to use the portal and no realistic email equivalent. One workflow moved completely beats five moved partially.

  5. Change how the firm responds to attachments

    When a document arrives by email, reply with the portal link rather than processing it silently. Adoption is a staff behaviour before it is a client behaviour, and staff will take the path of least resistance too.

  6. Use it for chasing, not just for storing

    Outstanding items, pending signatures and task status visible to the client turn a portal from an archive into something they check. This is also what removes the phone call asking where things are.

  7. Measure logins per client per quarter and act on the tail

    The clients who never log in are not a failure of the software. They are the ones who need the no-login upload route, and knowing who they are lets you stop chasing them into a portal they will never use.

What to check before you commit to a portal

These are the questions that are difficult to answer after migration and cheap to answer before it.

  • Where client separation is enforced, and what happens if the application requests the wrong record
  • What a client login can reach, and whether it can alter its own permissions
  • How an infrequent client gets back in after losing their credentials, and who at your firm can reset them
  • Whether there is a route for a client, or a prospect, who will never log in at all
  • What the signer is asked to prove, and what the completion certificate actually records
  • Which branding elements are included on your plan and which require a higher one
  • What happens to documents and access when an engagement ends, and who can delete them

Questions

Straight answers.

The questions firms ask about client management and portals, including the ones where the answer is no.

Will clients actually use a portal?

Some will, and it depends far more on rollout than on software. The clients who adopt fastest are the ones with something waiting for them on the first visit and a workflow that has no email alternative. Expect a tail of clients who never log in, and plan for them with a no-login upload route rather than treating them as a problem to be solved with more reminders.

Is a client code and PIN less secure than a password?

Different rather than simply weaker. A PIN has less entropy than a strong password, but most portal passwords are not strong, and the practical failure of password logins is the abandoned reset rather than a brute force attack. The relevant controls are how PINs are issued and reset, whether attempts are rate-limited, and what a session can reach once it is open. Judge the model on those, not on the credential type alone.

Can one client see another client’s documents?

They must not be able to, and the answer worth having is where that is enforced. If the separation is only applied when the application builds a page, a bug or a crafted request can defeat it. If it is enforced in the database, the query cannot return another client’s rows even when the application asks. Accupe enforces per-client isolation with row-level security in the database.

Are electronic signatures legally valid for accountancy work?

For ordinary business documents such as engagement letters, approvals and most tax authorisations, yes in both the UK and the UAE. The questions that decide whether a signature stands up are evidential: who signed, what they signed, when, and whether the document has changed since. Deeds and a small number of other instruments have additional formalities, so check those document classes once rather than assuming.

What is the difference between a simple, advanced and qualified electronic signature?

Broadly, a simple signature is any electronic indication of intent, an advanced signature is uniquely linked to the signer with tamper detection on the signed document, and a qualified signature adds a certificate from a trust service provider and secure signature creation hardware. Almost all professional services work sits comfortably at the simple or advanced level; a qualified signature is rarely needed and is a much heavier process.

What about the clients who will never log in?

Give them a route that requires no login at all. A page that accepts uploads against a client reference, and cannot be used to browse or download anything, gets you the document without provisioning access. It also works for prospects, who cannot have portal credentials because they are not clients yet. Treat it as a lower-security intake channel and keep anything sensitive behind the real login.

Do we need our own domain for the portal?

Not to function, but it helps with the thing portals are worst at, which is looking legitimate to a client who was not expecting the message. If you cannot have a custom domain, the higher-value fix is usually the notification emails: a client is far more likely to be suspicious of an email from an unfamiliar sender than of a URL they never look at.

What happens to a client portal when the engagement ends?

Decide before you roll out. Access should be withdrawable, retention should be a policy rather than a default, the client should know what they can take with them, and deletion should be restricted to named people. Three lines in the engagement letter now avoids a difficult conversation with a former client later, and it also answers the data protection question you would otherwise have to answer under pressure.

Why does portal sign-in use a client code and PIN rather than an email link?

Because a professional services client is often not a single person. A company’s file may be touched by two directors, a bookkeeper and a spouse, and an email-addressed link ties access to one inbox and leaks when it is forwarded. A client code identifies the client record and a PIN authenticates the person holding it, which keeps access attached to the relationship rather than to whoever happens to control a mailbox. It also means a firm can reissue access without waiting on a mail provider.

What should a client never see in their own portal?

Anything that represents the firm’s internal reasoning rather than the client’s business: staff notes, internal review comments, time entries, margin, and any document filed for the firm’s own compliance rather than the client’s benefit. Accupe defaults new tasks to hidden and requires an explicit opt-in per task for exactly that reason. The safe default is that visibility is a decision somebody made, never something that happened because nobody checked.

What is the realistic adoption curve for a client portal?

Slower than the firm expects and highly segmented. Clients who already work digitally will use it immediately. Clients who send everything by email will keep sending everything by email until the firm stops answering that way, and a portal introduced without changing the firm’s own habits simply becomes a second place documents live. The firms that get adoption tend to do two things: they route new clients through the portal from onboarding so it is the only channel those clients ever know, and they set a date after which document requests for existing clients go out as portal links rather than attachments. Expect a long tail who never adopt, and decide in advance whether that is acceptable or whether those relationships need a conversation.
